Laws in Yellowstone National Park are established and enforced through a combination of federal regulations and site-specific rules tailored to the park's unique needs. At the core of this legal framework is Title 36 of the Code of Federal Regulations (CFR), which outlines the general rules governing all National Park Service lands. However, each park also faces distinct challenges and conditions, which is why Yellowstone’s superintendent issues a compendium—a document that supplements the CFR with local regulations specific to the park. To know the full set of laws that apply in Yellowstone, you must review both the CFR (external link) and the compendium (published in full on this page). Together, they provide the legal basis for protecting Yellowstone’s natural and cultural resources while ensuring public safety and enjoyment.
The following commonly cited regulations outline activities that are prohibited in Yellowstone:
Bringing firearms (guns) in certain facilities in this park (such as visitor centers and government offices): those places are marked with signs at all public entrances. 18 USC §930(a)
Launching, landing, or operating unmanned aircraft (drones) on lands and waters. 36 CFR §1.5(f); SC p.16
Willfully remaining near or approaching wildlife, including nesting birds, within any distance that disturbs or displaces the animal. 36 CFR §1.5(f); SC p.24
Using electronic equipment capable of tracking wildlife. 36 CFR §1.5(f); SC p.24
Smoking is prohibited in geyser basins or on trails. There is no smoking in buildings or within 25 feet of building entrances. 36 CFR §2.21(a); SC p.43-44
Removing or possessing natural or cultural resources (such as wildflowers, antlers, rocks, and arrowheads). 36 CFR §2.1(a)(1)
Throwing anything into thermal features. 36 CFR §2.1(a)(3)
Hunting or feeding wildlife. 36 CFR §2.2 (a)
Spotlighting wildlife (viewing with lights). 36 CFR §2.2(e); SC p.33
Camping outside of designated areas. 36 CFR §2.10(b)(10)
Traveling off-road by vehicle. 36 CFR §4.10(a)
Traveling off-road by bicycle. 36 CFR §4.30(h)(1)
Traveling off boardwalks or designated trails in hydrothermal areas. 36 CFR §7.13(j)
Swimming in hot springs. 36 CFR §7.13(m)
Compendium
Last update: September 17, 2026
Read the Superintendent's Compendium below, or download the signed PDF with accurate line-by-line citations.
The Superintendent’s Compendium does not repeat regulations found in Title 36 Code of Federal Regulations (36 CFR), United States Code and other CFR Titles, which are enforced without further elaboration at the park level. The Superintendent’s Compendium is the summary of park specific rules implemented under 36 CFR. It serves as public notice, identifies areas closed to public use, provides a list of activities requiring either a special use permit or reservation, and elaborates on public use and resource protection regulations pertaining specifically to the administration of the park.
The regulations contained in 36 CFR, Parts 1-7, are the basic mechanism used by the National Park Service to preserve and protect the natural and cultural resources of the park and to protect visitors and property within the park. Parts 1 through 6 are general regulations applicable to all areas of the National Park system and Part 7 contains special regulations specific to individual parks. Each of these Parts has many sections and subsections articulating specific provisions. Within some of these Part 1-7 sections and subsections, the Superintendent is granted discretionary authority to develop local rules to be responsive to the needs of a specific park resource or activity, park plan, program, and/or special needs of the public.
This Compendium should be used in conjunction with Title 36 CFR, Parts 1-7, to more fully understand the regulations governing the use and enjoyment of all the areas of the National Park System.
A copy of Title 36, CFR, can be purchased from the U.S. Government Printing Office or found on the Internet at: https://www.ecfr.gov/current/title-36.
Laws and Policies Allowing the Superintendent to Develop This Compendium
The National Park Service is granted broad statutory authority under 54 United States Code (U.S.C.) Section 100101 et.seq. (Omnibus Public Land Management Act of 2009, previously Organic Act of 1916, as amended) to “…regulate the use of the National Park System by means and measures that conform to the fundamental purpose of the System units, which purpose is to conserve the scenery, natural and historic objects, and wild life in the System units and to provide for the enjoyment of the scenery, natural and historic objects, and wild life in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” [54 U.S.C. Section 100101(a)].
In 1970, Congress amended the National Park Service Organic Act to clarify its intentions as to the overall mission of the National Park Service. Through the General Authorities Act of 1970 (16 U.S.C. Sections 1a1-1a8), Congress brought all areas administered by the National Park Service into one National Park System and directed the National Park Service to manage all areas under its administration consistent with the Organic Act of 1916.
In 1978, Congress amended the General Authorities Act of 1970 and reasserted System-wide the high standard of protection defined in the original Organic Act by stating “Congress further reaffirms, declares, and directs that the promotion and regulation of the various areas of the National Park System, as defined by Section 1 of this Title, shall be consistent with and founded in the purpose established by Section 1 of this Title, to the common benefit of all people of the United States.”
54 U.S.C. Section 100501 defines the National Park System as “… any area of land and water administered by the Secretary, acting through the Director, for park, monument, historic, parkway, recreational, or other purposes.”
In addition to the above statutory authority, the Superintendent is guided by established National Park Service policy as found in the National Park Service Management Policies (2006). The Superintendent is also guided by more specific policies promulgated by the Director of the National Park Service, in the form of Director’s Orders. As stated in the Management Policies, the primary responsibility of the National Park Service is to protect and preserve our national natural and cultural resources while providing for the enjoyment of these resources by visitors and other users, as long as use does not impair specific park resources or overall visitor experience. The appropriateness of any particular visitor use or recreational experience is resource-based and will vary from park to park; therefore, a use or activity that is appropriate in one park area may not be appropriate in another. The Superintendent is directed to analyze overall park use and determine if any particular use is appropriate. Where conflict arises between use and resource protection, where the Superintendent has a reasonable basis to believe a resource is or would become impaired, then that Superintendent is obliged to place limitations on public use.
Consistency of This Compendium with Applicable Federal Law and Requirements
The Superintendent’s Compendium is not considered a significant rule requiring review by the Office of Management and Budget under Executive Order 12866. In addition, this Compendium will not have a significant economic effect on a number of small entities nor impose a significant cost on any local, state, or tribal government, or private organization, and therefore does not fall under the requirements of the Regulatory Flexibility Act or Unfunded Mandates Reform Act. The actions and requirements described in this Compendium are found to be categorically excluded from further compliance with the procedural requirements of the National Environmental Policy Act (NEPA) in Department of the Interior (DOI) Guidelines 516 DM 12 and as such, an Environmental Assessment will not be prepared.
Development of the Requirements of the Superintendent’s Compendium
As outlined above, the National Park Service has broad authority and responsibility to determine what types of uses and activities are appropriate in any particular National Park System area. The requirements of the Superintendent’s Compendium are developed through an analysis and determination process. The decision criteria used during this process are:
Is the use or activity consistent with the National Park Service Organic Act and National Park Service policy?
Is the use or activity consistent and compatible with the park’s enabling legislation, management objectives, and corresponding management plans?
Will the use or activity injure the park’s protected natural and cultural resources and other protected values?
Will the use or activity disturb or conflict with wildlife, vegetation, and environmental protection actions and values?
Will the use or activity conflict with or be incompatible with traditional park uses and activities?
Will the use or activity compromise employee or public safety?
Applicability of the Compendium
The rules contained in this Compendium apply to all persons entering, using, visiting, or otherwise present on federally owned lands, including submerged lands and waters administered by the National Park Service within the legislative boundaries of the park. This includes all waters subject to the jurisdiction of the United States, including all navigable waters.
The rules contained in this Compendium shall not be construed to prohibit administrative activities conducted by the National Park Service or its agents in accordance with approved general management and resource management plans, or in emergency operations involving threats to life, property, or park resources.
Enforcement of Compendium Requirements
National Park Service Law Enforcement Park Rangers enforce the requirements of the United States Code, 36 CFR, and this Superintendent’s Compendium.
Penalties for Not Adhering to the Compendium Requirements
A person who violates any provision of the regulations found in 36 CFR, Parts 1-7, or provisions of this Compendium, is subject to a fine as provided by law (18 U.S.C. 3571) up to $5,000 for individuals and $10,000 for organizations, or by imprisonment not exceeding six months (18 U.S.C. 3559), or both, and shall be adjudged to pay all court costs associated with any court proceedings. In addition to any fines or imprisonment, an individual may be subject to a period of probation not to exceed five years in length (18 USC 3561).

Determination: The Superintendent has determined these closures are necessary for the protection and repopulation of Grizzly Bears in Yellowstone National Park and the Greater Yellowstone Ecosystem.
Bird nesting closures
Annually, from May 1 through September 15, all lands within ¼ mile or any other distance designated on signs or maps of active sensitive bird nesting sites are closed to all public access.
The following locations are known, reoccurring nesting sites that close in accordance with this section:
Beula Lake
Blacktail Ponds
Floating Island Lake
Grebe Lake
Heart Lake
Ice Lake
The mouth of the Lewis Channel
Riddle Lake
Swan Lake
Tanager Lake
Wolf Lake
Yellowstone Lake locations
Between Campsite 7N2 and 7N4, South Arm of Yellowstone Lake
Campsite 7L7, South Arm of Yellowstone Lake
Frank Island, except the picnic area
Molly Islands
Peale Island
Stevenson Island
Determination: The Superintendent has determined that this closure is necessary for the protection of bird species during the sensitive nesting period and that a ¼ mile distance is reasonable considering U.S. Fish and Wildlife Service guidance. Should documentation of fledging or nesting failure occur earlier than September 15th, closures may be lifted by the removal of posted signs.
Caves
All caves within the park are closed to public use, except when a permit has been issued by the Superintendent.
Determination: This public use limit has been established in accordance with the Federal Cave Resource Protection Act of 1988 (16 USC § 4301-4309) and departmental policy, which states all caves located on National Park Service lands are “significant caves.” The permit requirement is done to protect sensitive cave resources and provides a protection for the public from potentially accessing areas with concentrated toxic gas.
McMinn Bench sheep closure
The McMinn Bench sheep wildlife protection area is closed to all public access (view full PDF with map).
Determination: The Superintendent has determined this closure is necessary for the protection and repopulation of Bighorn Sheep in Yellowstone National Park and the Greater Yellowstone Ecosystem.
Elk calving closures
Beginning in approximately mid-May through approximately mid-June and/or when signed as closed, the Mammoth Parade Grounds are closed to all foot travel (view full PDF with map).
Determination: The National Park Service has determined that cow elk become aggressive and territorial during the spring calving season and in recent years have caused serious injuries to employees and visitors in the Mammoth Hot Springs area. In an effort to protect humans from dangerous surprise encounters with elk, the Parade Grounds have been posted as closed to all travel during the duration of calving season (approximate dates of mid-May to mid-June). While elk may be present in many different locations of the Mammoth Hot Springs developed area, the Parade Grounds have pedestrian foot paths through sage brush areas where elk calves are easily stashed, and the elk can be difficult to see until a person is too close. An elk attack resulting in serious injury occurred on a pedestrian path on the Parade Ground during the 2019 calving season.
Construction areas
Construction or demolition areas are closed to public access except where a designated route and means of travel have been established by the Superintendent.
Determination: The Superintendent has determined that this prohibition is necessary for public and traffic safety.
Jumping, diving, rappelling
Jumping, diving, or rappelling off any bridge or structure in the park is prohibited.
Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.
Unmanned aerial systems
The term unmanned aircraft applies to restrictions listed in this section. Definitions can be found in "Part 1: 36 CFR § 1.4 – What terms do I need to know?" of this document.
Launching, landing, or operating an unmanned or remotely piloted aircraft from or on lands and waters administered by the National Park Service within the boundaries of Yellowstone National Park is prohibited except as approved in writing by the Superintendent.
Determination: The Superintendent has determined that unmanaged or unrestricted recreational use of unmanned aircraft within Yellowstone National Park will conflict with or impact a variety of park uses, including visitor experience of unimpaired view sheds; the disturbance, displacement, or harassment of park wildlife to include threatened and endangered species; present potential for impacts or damage to sensitive thermal areas; creation of public safety hazards per operation near roadways or large aggregations of visitors; and visual or aural impacts to wilderness character and values within the park backcountry. Less restrictive measures were not considered sufficient due to the rapidly expanding and evolving use of UAs throughout the world. Section 1.5 of National Park Service Management Policies 2006 provide that a new form of park use may be allowed within a park only after a determination has been made by the park Superintendent that it will not result in unacceptable impacts on park resources and values.
Firearm ranges
All firearm ranges, to include the administrative roads that access them, are closed to public access.
Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.
Obsidian Cliff
Obsidian Cliff is closed to all public access.
For the purposes of this part, “Obsidian Cliff” means all areas within the following exterior boundary: a straight line from 44°50’55.00” N, 110°44’07.94” to the peak of Horseshoe Hill; a straight line from the peak of Horseshoe Hill to the west bank of Solfatara Creek; along the western bank of Solfatara Creek to its intersection with the Solfatara Creek trail; 100 feet off the north edge of Solfatara Creek Trail to Solfatara North trailhead; 100 feet off the east edge of Grand Loop Road to 44°50’55.00”N, 110°44’07.94”.
Determination: The Superintendent has determined this closure is necessary to provide for the protection of cultural resources associated with Obsidian Cliff National Historic Landmark. The values associated with Obsidian Cliff are still strong today, making recreational activities at the site inappropriate.
Road closures
Roads closed to non-official use: All roads, including service and administrative roads, designated by signs and/or locked gates, or barricaded with logs and/or boulders. Foot traffic is permitted unless specifically posted otherwise. Pets and bicycles are prohibited.
Grand Loop Road and park Entrance Roads
Starting November 1 until spring opening in April or May, the Grand Loop Road and park entrance roads are closed to wheeled motor vehicle use by the public, except for the following sections of park road which remain open year-round:
North Entrance Station to Mammoth Hot Springs
Mammoth Hot Springs to Upper Terrace Drive
Mammoth Hot Springs to Tower Junction
Tower Junction to the Northeast Entrance Station
Firehole Canyon Drive is closed to wheeled buses, trailers, and recreational vehicles.
Firehole Lake Drive is closed to vehicles weighing six tons or more at the direction of Federal Highways.
Determination: The Superintendent has determined that these use prohibitions and restrictions are necessary for public safety and resource protection.
Stephens Creek Administrative Facility
The Stephens Creek Administrative Facility is closed to all public access.
For the purpose of this part, “Stephens Creek Administrative Facility” means Stephens Creek access road, Stephens Creek corral, Stephens Creek barn and infrastructure, Stephens Creek firearms range, and the surrounding area as fenced and signed and as shown on the map (view full PDF with map).
In addition, temporary closures may be implemented throughout the year in the Stephens Creek Administrative Facility area to accommodate wildlife management operations. All areas within these additional temporary closures are closed to public access.
Determination: The Superintendent has determined that this closure is necessary for resource protection, as well as public and employee safety.
Storm Point Trail area
The Storm Point Trail in the vicinity of Yellowstone Lake is closed to all off trail travel as marked in the map below and signs placed at the closure (view full PDF with map).
Determination: The Superintendent has determined this closure is necessary for the protection and repopulation of Sand Verbena, a rare endemic plant in Yellowstone National Park and the Greater Yellowstone Ecosystem.
Sylvan Pass avalanche control area
The Sylvan Pass avalanche control area is closed to all public access.
For the purposes of this part, “Sylvan Pass avalanche control Area” means the entire south aspect of Hoyt Peak, from a point 1.5 miles east of Avalanche Peak Trailhead to a point 1.6 miles east of Avalanche Peak Trailhead.
Determination: The Superintendent has closed this area year-round for public safety. Over the winter months, National Park Service staff conduct avalanche mitigation operations, to include the use of explosive rounds. Regardless of season, the area listed above may contain unexploded ordnance.
The Sylvan Pass howitzer platform and the administrative road that accesses the platform are closed to public access.
Determination: The Superintendent has closed this area for public safety. Over the winter months, National Park Service staff conduct avalanche mitigation operations, to include the use of explosive rounds fired off from this location. The tools used to conduct avalanche mitigation in the area are left on site and the nature of the equipment is dangerous.
Agricultural and domesticated wild animals
The possession of an agricultural or domesticated wild animal is prohibited unless the Superintendent has provided written authorization.
Determination: The Superintendent has determined that these use prohibitions and restrictions are necessary for public safety and resource protection.
Foot travel within Yellowstone Canyon
Foot travel within the Yellowstone Canyon between Chittenden Bridge and Upper Falls is restricted to designated trails and boardwalks.
Foot travel within the Yellowstone Canyon between Inspiration Point and Silver Cord Cascade is restricted to designated trails and boardwalks.
Determination: The Superintendent has determined the restrictions above are similar and connected to the areas closed in 36 CFR 7.13(j). Foot travel is also restricted to boardwalks and trails within the Yellowstone Canyon between the Upper Falls and Inspiration Point. These restrictions have been determined necessary to provide for visitor safety and protect thermal and natural resources.
36 CFR § 1.5(a)(2)
Designate areas for a specific use or activity or impose conditions or restrictions on a use or activity.
The terms invasive (nonnative) species and thermal area apply to restrictions listed in this section. Definitions can be found in "Part 1: 36 CFR § 1.4 – What terms do I need to know?" of this document.
Filming, still photography, and audio recording activity
May require a permit, consistent with 54 U.S.C. § 100905.
Filming, still photography, and audio recording activity that occurs in closed areas, requires exclusive use of a site or area, or involves a set or staging equipment other than handheld equipment (such as a tripod, monopod, and handheld lighting equipment) requires a permit, unless the activity is affiliated with an activity or event that has been allowed under a written authorization, such as a special use permit.
Filming, still photography, and audio recording that involves more than eight individuals requires a permit, unless the National Park Service has specifically notified an individual or group that a permit is not required, or if the activity is affiliated with an activity or event that has been allowed under a written authorization, such as a special use permit.
If a permit is required for the reasons stated above, or if the National Park Service otherwise determines and then notifies an individual or group that a permit is required for a filming, still photography, or audio recording activity, then engaging in that activity without a permit is prohibited. Violating a term or condition of a permit issued by the National Park Service for a filming, still photography, or audio recording activity is prohibited, and may result in the suspension or revocation of the permit, in addition to any penalties that may apply under 36 CFR § 1.3.
Determination: Federal law at 54 U.S.C. § 100905 states that permits and fees are not required for filming, still photography, or audio recording in park areas if certain requirements are met. These requirements address various topics, including, but not limited to, group size, location, equipment, potential impacts to resources and visitors, and the likelihood that the National Park Service will incur related administrative costs. If any of these requirements are not met, the law allows the Secretary of the Interior, acting through the National Park Service, to require a permit for the subject activity. Permit requirements are imposed by the superintendent under discretionary authority provided by 36 CFR § 1.5(a)(2), which allows the superintendent to impose conditions or restrictions on a use or activity, consistent with applicable legislation, to implement management responsibilities. The general regulations for permits in 36 CFR § 1.6 do not apply to permits issued for filming, still photography, and audio recording, which instead are governed by the statutory provisions in 54 U.S.C. § 100905. The imposition of permit requirements, on a case-by-case basis, for filming, still photography, or audio recording does not require rulemaking under 36 CFR § 1.5(b). Requiring a permit with reasonable terms and conditions in accordance with statutory requirements at 54 U.S.C. § 100905 is not highly controversial, will not result in a significant alteration in the public use pattern of the System unit, will not adversely affect the System unit’s natural, aesthetic, scenic or cultural values, or require a long-term or significant modification in the resource management objectives of the System unit, because the permit requirement is limited in time and scope to the specific activities authorized by the permit, which contain terms and conditions that protect the values, resources, and visitors of the System unit, and implements federal law.
Activity or use restriction
Use of unattended, automatic, motion-detection, or remote controlled still photography, videography, and audio recording devices is prohibited.
Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.
Boating and water use activities
A Yellowstone aquatic invasive species (AIS) inspection, as specified in the sections below, is required to obtain a general permit for boating in the park.
AIS inspections will be completed by an authorized inspector from the park on all vessels and related equipment that will contact park waters.
Following an AIS inspection, the Yellowstone AIS decal must be displayed on the boat permit decal, which must be displayed on the vessel in accordance with the boating regulations.
The following are required to obtain an AIS decal:
All vessels and related equipment must pass an AIS inspection. Yellowstone requires all watercraft to be cleaned, drained, and dried prior to launch.
All vessels must not have a ballast tank or similar areas that cannot be visually inspected, except as specifically authorized by the Superintendent.
Effective May 25, 2024, all vessels with inboard (v-drive and direct drive), inboard/outboard (sterndrive), or inboard jet propulsion systems, as well as sailboats, will be subject to a 30-day quarantine and sealed to their trailers prior to launching in park waters. Yellowstone National Park, Wyoming Game & Fish Department, Montana Fish, Wildlife & Parks, Idaho State Department of Agriculture, Colorado Parks & Wildlife, Utah Division of Wildlife Resources, Oregon Department of Fish & Wildlife, and Washington Department of Fish & Wildlife seals will be honored pending verification of the 30-day quarantine period by a certified Yellowstone inspector during the mandatory AIS inspection prior to launching. Proof of quarantine shall be provided to the inspector in the form of an intact seal and the accompanying agency inspection receipt from the date of the seal application.
A boat permit issued in accordance with this part is only valid during the dates specified on the AIS decal, or until the vessel or related equipment exits the park.
All vessels and related equipment, regardless of previous AIS inspections, must be re-inspected, in accordance with this part, upon reentry and intended launch into Yellowstone National Park waters.
Vessels and related equipment with evidence of dead or live Dreissenid mussels, as well as vessels and related equipment previously fouled by Dreissenid mussels, are prohibited regardless of cleaning or dry time.
It is prohibited to allow any vessel or related equipment to contact any park waters without a valid Yellowstone AIS inspection or seal as specified in this part.
Determination: The Superintendent established this restriction for the protection of natural resources and to address the risk of introducing Dreissenid mussels and other AIS to Yellowstone National Park waters. Dreissenid mussels are a highly invasive species and have caused irreversible changes in waterways in the Midwestern and Eastern United States and in the Colorado River basin, to include Lake Mead and Lake Powell. Sealed internal water ballast tanks pose an elevated risk of accidental transportation and introduction of AIS because they are less likely to completely drain or be fully decontaminated. In addition, Yellowstone National Park requires an inspection of all watercraft to make sure they are cleaned, drained, and dry, and this is not possible with sealed tanks. Large, complex, trailered watercraft with inboard, inboard/outboard, and inboard jet propulsion systems, as well as sailboats, pose the highest risk of transporting and introducing Dreissenids because they are difficult to inspect and less likely to completely drain/dry or be fully decontaminated (the manual application of hot water is not always 100% effective in removing all mussels). A 30-day quarantine provides sufficient drying time to mitigate the risk of Dreissenid mussel introduction associated with these watercraft, regardless of their use history, time spent in a waterbody, ambient temperature, humidity, etc. The launch of fouled watercraft increases the chances of false mussel detection by routine environmental DNA monitoring of park waters. A general permit is required to boat in the park, as referenced in 36 CFR § 7.13(d)(1)(i). The Superintendent has determined an AIS inspection and sections detailed in this part are necessary to obtain a general permit for boating in the park to prevent the introduction and spread of AIS in Yellowstone National Park waters.
All bilge and ballast plugs or other barriers that prevent water drainage from a vessel shall be removed and remain open while a vessel is being stored, left unattended, or transported by land within the park.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
Anchoring a vessel on Yellowstone Lake in the following locations is prohibited:
Bridge Bay Marina.
Grant Village Launch Ramp Lagoon.
Within 300 yards of the shoreline between Lake Hotel and the entrance to Bridge Bay Marina.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
Anchoring or beaching any vessel overnight in the park is prohibited, except if a person has an active and valid Yellowstone National Park Backcountry Use Permit.
Docks on Yellowstone Lake are designated for Yellowstone National Park Backcountry Use Permittees. Persons without a Yellowstone National Park Backcountry Use Permit may only use these docks when the associated backcountry campsite is not in use.
It is prohibited to transport a vessel or related equipment that is known to have invasive species attached through the park.
Landing or beaching a vessel in the following locations is prohibited:
In or within 25 yards of a thermal area, except at the designated boat landing area for Shoshone Geyser Basin.
In an area closed to public use.
In areas as designated by signs or as posted on maps in visitor use areas.
On the shoreline of Yellowstone Lake between Little Thumb Creek and the south end of West Thumb Geyser Basin.
Vessels are prohibited within 25 yards of shoreline thermal features (ie, West Thumb Geyser Basin, Potts Basin and Back Basin) and within 25 yards of submerged thermal features that emerge during periods of low water.
It is prohibited to operate a vessel over submerged thermal area(s) where doing so damages the thermal area. Striking a thermal area, both on shore or underwater, with a vessel or anything from a vessel, such as with a paddle, pole, or anchor is also prohibited.
Power-driven vessels on Yellowstone Lake may be used in areas restricted to hand-propelled vessels if the device that powers the vessel has been completely removed from the transom or is non-operational and completely fixed out of the water.
Power-driven vessels from Lewis Lake may be used on Shoshone Lake only if the device that powers the vessel has been removed. Storage requirements for the device are detailed in this Compendium under Part 2 – Resource Protection, Public Use, and Recreation: 36 CFR § 2.22(a)(2).
The park’s boating season begins the Saturday immediately prior to Memorial Day and ends October 31. Boating outside of these dates is prohibited.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
Cooke City, Montana, area resident permit restrictions
In lieu of paying a Yellowstone National Park Recreation Fee, Cooke City, Montana, area residents may obtain a free permit, as authorized by the Superintendent, for non-recreational travel through the park between the north and northeast entrances.
Determination: The Superintendent has determined that this is necessary to protect the resource and enhance public safety and accessibility.
Resource protection
The possession or consumption of food and beverages is prohibited in all thermal areas, except when contained in a pack-like container for carrying purposes. Water is not included in this prohibition.
Determination: The Superintendent has determined that this restriction is necessary to protect and prevent impact to thermal resources.
Transporting or hauling plant products, plant byproducts, plant waste products, or minerals into or through the park is prohibited, except when a person has received written authorization from the Superintendent. Only securely wrapped State certified weed-free forage including pelletized or steam rolled feed grains, or certified weed-free hay cubes may be used in the park.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
Wildlife protection
The term bear spray applies to restrictions listed in this section. Definitions can be found in "Part 1: 36 CFR § 1.4 – What terms do I need to know?" of this document.
The possession of bear spray for the strict purposes of protecting life and property against aggressive wildlife is permitted within the park.
Determination: The Superintendent has determined that the use of Bear Spray in a manner consistent with IGBC recommendation is appropriate as a deterrent to negative human/bear encounters.
The use or possession of any radio electronic signal receiving device capable of being set at wildlife research operation frequencies assigned to National Park Service, U.S. Fish and Wildlife Service, Interagency Bear Management Team, or any other permitted wildlife research organization within Yellowstone National Park is prohibited for the purposes of pursuing, tracking, harassing, or viewing wildlife or attempting to do any of the above.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
To protect park wildlife, the following are prohibited:
Knowingly approaching, remaining, viewing, or engaging in any activity:
Within 25 yards of any wildlife, except bears, wolves, and cougars.
Within 100 yards of bears, wolves, and cougars.
Within any distance that disturbs, displaces, or interferes with the free unimpeded movement of any wildlife.
Within any distance that creates or contributes to a potentially hazardous condition or situation.
Willfully using a motor vehicle to approach wildlife or in a manner that disturbs, displaces, or interferes with the free unimpeded movement of wildlife.
Failure to comply as directed by National Park Service staff (employees, volunteers, or agents) engaged in administering wildlife management protocols approved by the Superintendent.
Failing to remove oneself to prescribed distances during inadvertent, accidental, or surprise encounters with wildlife.
The prohibitions of this section do not apply to someone who is:
In compliance with written protocols approved by the Superintendent.
In accordance with the terms and conditions of a permit issued by the Superintendent.
Determination: The Superintendent has determined that these public use restrictions and requirements are necessary to maximize public safety, protect wildlife, and provide park staff with the flexibility to situationally manage dynamic, diverse, and rapidly evolving wildlife viewing opportunities.

Commercial tour group representatives may not accompany clients on hiking trails (other than the above listed areas), or guide outdoor recreation activities, unless conducted as an activity facilitated by a guide whom is authorized by a CUA, is the employee of an authorized CUA holder, or is the employee of a concessioner.
Entities that have a commercial use authorization application denied or an authorization suspended or revoked for administrative or criminal violations may not enter the park under the commercial entry fee for the applicable duration of denial or revocation. This restriction excludes entities that applied for a CUA but were denied based on the activity not fitting a CUA category, but who then opt to provide road-based tours under the commercial tour fee.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
Employee motor vehicle permits
Employee motor vehicle permits issued in accordance with 36 CFR § 7.13(b)(1) and 36 CFR § 7.13(b)(2) are only valid while the person is employed within the park and must be surrendered upon termination of employment.
Determination: The Superintendent has determined this condition is necessary for the proper use of the park by those no longer employed within the park.
Gyroscopically controlled mobility devices
The use of a Segway or other similar gyroscopically controlled device, in lieu of a manual or motorized wheelchair, is allowed by persons with disabilities who would otherwise only have the option of using a manual or power wheelchair under the following conditions:
A person using a Segway or a similar gyroscopically controlled device in the park would be medically determined to have a permanent disability that severely limits one or more major life functions. A permanent disability is a permanent physical, mental, or sensory impairment that substantially limits one or more major life activities, such as caring for oneself, performing manual task, walking, seeing, hearing, speaking, breathing, learning, and working.
Persons claiming disability will show proof of medically determined permanent disability or eligibility for receiving benefits under federal law following the guidelines in effect for obtaining an America the Beautiful Access Pass (e.g. a statement by a license physician).
When use of a gyroscopically controlled mobility device is permitted, the following conditions will apply:
Segways or similar gyroscopically controlled devices are permitted on sidewalks, formalized paved overlooks, and in campgrounds.
Segways are prohibited on park roads, to include their shoulders, and boardwalks.
Segways may not be operated at speeds greater than 3 mph.
Determination: The Superintendent has determined that these use conditions are necessary to ensure public safety and the safety of ADA defined users.

While stopped in traffic or a construction line.
While actively loading or unloading.
While warming up a motor vehicle’s engine for no longer than 10 minutes in developed areas or parking lots.
While warming up an engine or motor vehicle away from concentrated visitor use or residential area.
Determination: Idling engines and motor vehicles produce noise and noxious fumes that adversely affect air quality, park resources, and visitor health and experience. The Superintendent has established these conditions to protect park resources, promote better air quality in the park, and protect and enhance visitor experience. These conditions have been determined as the least restrictive means to ensure operators can still warm up engines or motor vehicles for optimum use and to heat and cool motor vehicle interiors for passenger comfort without negatively impacting park resources and the public.
Unattended pets in vehicles
It is prohibited to leave or confine a pet in an unattended motor vehicle under conditions that endanger the health or well-being of a pet due to heat, cold, lack of adequate ventilation, or lack of food or water, or other circumstances that could reasonably be expected to cause suffering, disability, or death to the pet.
Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

36 CFR § 2.10(d)
Food storage.
The terms bear resistant food container, core camp, equipment used to cook or store food, and food apply to restrictions listed in this section. Definitions can be found in "Part 1: 36 CFR § 1.4 – What terms do I need to know?" of this document.
In all park areas all food, lawfully taken fish or wildlife, garbage, and equipment used to cook or store food must be kept sealed in a vehicle, or in a camping unit that is constructed of solid, non-pliable material, or in a bear resistant food container (BRFC), or suspended at least 10 feet above the ground and 4 feet horizontally from a post, tree trunk, or other object, or suspended on an National Park Service established and designated food hanging pole. This restriction does not apply to park residents who are in compliance with the food storage conditions outlined in the Yellowstone National Park Housing Plan or to established National Park Service grills and fire grates in housing areas, picnic areas, and campgrounds.
Determination: The Superintendent has implemented food storage restrictions for the entire park to prevent park wildlife from obtaining food and becoming food conditioned, especially Black and Grizzly Bears. The Superintendent has determined these restrictions are necessary and the least restrictive means to protect park wildlife and the public. The Superintendent has added BRFCs and National Park Service established and designated food hanging poles as a legal means to store food because they are constructed to prevent park wildlife from obtaining food and becoming food conditioned. In some areas, National Park Service established bear resistant containers and food hanging poles may be the only food storage option aside from BRFCs. The Superintendent has determined these options help prevent further restrictions on the public while protecting park wildlife and the public.
The following conditions apply when using a BRFC for food storage:
In all areas, a BRFC must properly function in designed condition and be secured as prescribed by the manufacturer.
In backcountry campsites, a BRFC must be stored within core camp.
When undesignated camping, a BRFC must be stored 100 yards from any sleeping area.
In developed, frontcountry areas, a BRFC must be kept in a vehicle or in a camping unit that is constructed of solid, non-pliable material.
During the winter season BRFCs shall be utilized for frontcountry food storage in the interior, oversnow portions of the park. BRFCs may be stored on the exterior of a vehicle or on a snowmobile or tow sled.
Determination: Although BRFCs are designed to prohibit bears from accessing the contents within, the smells associated with them may still attract wildlife into camping areas. Requiring BRFCs to be stored in the manner above has been determined necessary by the Superintendent to prevent negative human and wildlife interactions, especially involving Black and Grizzly Bears. The Superintendent has determined these are the least restrictive means to protect park wildlife and the public.
All refuse receptacles placed outdoors are only designated as an approved method for dumping if it is of bear-proof construction or placed inside bear-proof enclosures.
Determination: The Superintendent has determined this condition is necessary to prevent park wildlife from becoming food conditioned, namely Black and Grizzly Bears. The Superintendent has determined this is the least restrictive means to protect park wildlife and the public.
Backcountry campsites and boat docks associated with backcountry campsites on Yellowstone Lake may be used for picnicking unless the backcountry site is being occupied by a person with an active and valid Yellowstone National Park Backcountry Use Permit.
Determination: The Superintendent has determined these picnicking restrictions are necessary and the least restrictive means to avoid conflict between park users.
36 CFR § 2.13(a)(1)
Designated areas, receptacles, and conditions for lighting and maintaining a fire:
A fire may be ignited and maintained only by using fuel sources designed and commonly used for warmth or the preparation of food, such as charcoal briquettes or natural firewood. Lighting or maintaining a fire with other materials including, but not limited to, flammable liquids, garbage, fireworks, plastics, aerosol canisters, batteries, or other manufactured or synthetic materials, is prohibited.
Determination: This action is necessary for the maintenance of public health and safety, protection of environmental or scenic values, protection of natural or cultural resources, and the implementation of management responsibilities. Materials other than approved combustibles – especially fire accelerants and substances prone to wind transport or explosion – creates serious risks when used to light or maintain fires. These combustibles can ignite or spread wildfires that directly threaten people and valuable resources and assets. The burning of manufactured or synthetic materials can contribute to air pollution, contaminate soil and water, and be toxic to humans and the environment. Less restrictive measures, such as an education campaign informing visitors of the risks of using certain materials to light or maintain a fire, would not be commensurate with the substantial risks associated with those activities and could lead to adverse outcomes that might be prevented by establishing an enforceable condition.
Except when seasonal fire restrictions based on local fire danger ratings have been established by the Superintendent, fires are permitted within the confines of National Park Service-designated and installed fire rings, grills, or grates in the following locations:
Picnic areas, unless the National Park Service has not designated and installed fire rings, grills, or grates.
All frontcountry campgrounds.
All backcountry sites, unless designated otherwise in a Yellowstone National Park Backcountry Use Permit.
Employee housing areas.
Determination: The Superintendent has determined the need for fires to be contained within National Park Service-designated fire receptacles to prevent unintentional wildfire ignitions. If seasonal restrictions are implemented on the use of fires within National Park Service-designated fire receptacles, the Superintendent has determined this process as the least restrictive means to manage their use. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.
Except when seasonal fire restrictions have been established by the Superintendent, fires contained within a commercially manufactured grill are permitted in all park areas.
Determination: The Superintendent has determined the need for fires to be contained within commercially manufactured charcoal grills to prevent unintentional wildfire ignitions. If seasonal restrictions are implemented on the use of fires within commercially manufactured charcoal grills, the Superintendent has determined this process as the least restrictive means to manage their use. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.
36 CFR § 2.13(a)(2)
Use restrictions for stoves and lanterns:
Except when seasonal fire restrictions have been established by the Superintendent, the use of stoves and lanterns are permitted in all park areas.
Determination: The Superintendent has determined no restrictions are necessary for the use of stoves and lanterns unless seasonal weather and fire danger dictate otherwise. If seasonal restrictions are implemented, the Superintendent has determined this process as the least restrictive means to manage the use of stoves and lanterns. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.
36 CFR § 2.13(b)
Conditions for extinguishing fires:
Any fuel used to light and maintain a fire, including coals and remains, must be cold to touch prior to abandonment.
Determination: The Superintendent has determined that these conditions are necessary and the least restrictive means to protect park resources and the public from an unintentional wildlife ignition.
