Boreal Toad Protection
For the protection of sensitive breading areas, fragile egg masses, tadpoles, young and adult populations of the Boreal Toad, Spruce Lake is closed annually from May 15 through September 30. This area may be subject to further closures.
Launching, landing, or operating an uncrewed or remotely piloted aircraft from or on lands and waters administered by the National Park Service within the boundaries of Rocky Mountain National Park is prohibited except as approved in writing by the Superintendent.
Justification: NPS Management Policies require caution when a park is confronted with a new park use such as unmanned aircraft. The majority of Rocky Mountain National Park is designated Wilderness where the use of motorized equipment is prohibited. Additionally, in 1998 Congress passed the Rocky Mountain National Park Overflights Act which prohibits commercial air tours over the park, the intent of which is to aid in the protection of park resources and values from such intrusions.
The 2013 Foundation Document identifies fundamental resource values that are essential to achieving the purpose of the park and maintaining its significance. Among these are the protection of wildlife in a natural setting, maintaining wilderness character such as opportunities for solitude, prevention of unreasonable noise that might interfere with public enjoyment, and protection of outstanding scenic vistas. Accordingly, consistent with Service-wide interim policy and until the National Park Service can determine whether specific uses of unmanned aircraft are appropriate and will not cause unacceptable impacts, this closure will remain in place.
(a)(2)Designate areas for a specific use or activity or impose conditions or restrictions on a use or activity.
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 NPS 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 NPS 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 NPS 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.
Federal law at 54 USC § 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 NPS will incur related administrative costs. If any of these requirements are not met, the law allows the Secretary of the Interior, acting through the NPS, 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 USC § 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 USC § 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.
Metal Equipment at Hidden Valley Snow Play Area
For public safety reasons, the use of metal sleds (runner type or otherwise) or any metal edged equipment is prohibited in the Hidden Valley Snow Play Area.
Research Natural Areas
Portions of Specimen Mountain, West Creek, and Paradise Park are managed as Research Natural Areas. Foot traffic is allowed but not encouraged. Only day use activities are authorized, with overnight stays and pack animal use prohibited.
Specimen Mountain
Specimen and Shipler Mountains above 10,800 feet elevation and Willow Creek drainage to the northwest boundary of the park at about 9,880 feet; an area of approximately 9,056 acres. Specimen Mountain (12,489 feet) lies on the Continental Divide draining both directions, while Willow Creek drains into the Cache la Poudre River, which flows east.
Paradise Park
Paradise Park includes the drainage of Paradise Creek above the 10,000 feet elevation level and covers approximately 6,032 acres. Paradise Creek lies west of the Continental Divide in the southwest corner of the park and drains into a tributary of the Colorado River.
West Creek
This area includes West Creek and Fox Creek drainage on the east slope of the Mummy Mountain Range. Elevations range from 8,000 feet at the east boundary of the park to 13,425 feet on Mummy Mountain, an area of approximately 9,043 acres. These drainages flow into a tributary of the Big Thompson River.
Day Use Picnicking
Day use picnicking is prohibited in the following campgrounds from the Friday before Memorial Day through the end of September:
Aspenglen Campground
Glacier Basin Campground
Longs Peak Campground
Moraine Park Campground
Timber Creek Campground
Any picnicking which interferes with overnight campers is prohibited at all times.
McGraw Ranch/Cow Creek Trailhead Parking Lot
The McGraw Ranch/Cow Creek Trailhead Parking Lot is designated as a first-come, first-served parking facility, which requires a parking permit for overnight parking associated with Wilderness camping. No parking fee is charged.
The facility will accommodate fifteen (15) passenger vehicles and one (1) horse trailer, parked parallel where posted signs allow, with all tires on the graveled roadway.
This public use limit is to manage visitor use for an area accessed by a private road. The facility borders a major wildlife corridor and is adjacent to the Comanche Peaks Wilderness Area.
Car Idling
Idling a diesel engine or any vehicle engine which produces noxious exhaust is restricted to loading or unloading passengers. This does not preclude a vehicle from a reasonable warm-up period away from concentrated visitor use areas.
Tundra Closure Areas
Restricting use in these areas is for the protection of fragile alpine tundra from damage caused by heavy, concentrated foot travel.
Note: All areas above tree line, along Trail Ridge Road and Old Fall River Road, are designated as Tundra Protection Zone. An additional focus on this area will be completed through outreach programs to ensure that this fragile resource is protected and utilized appropriately to ensure its protection commensurate with visitor enjoyment.
The three (3) designated Tundra Closure Areas are described as:
Alpine Visitor Center to Lava Cliffs
From Alpine Visitor Center to south of Lava Cliffs parking lot and between the contours of Trail Ridge Road and the adjacent ridge to the east, inclusive of Lava Cliffs and Iceberg Lake. South of and adjacent to Lava Cliffs parking lot to Tundra Curves and on both sides of Trail Ridge Road to Tundra Curves.
Rock Cut
Adjacent to the parking areas on both north and south side of Trail Ridge Road and along Tundra Communities Trail corridor. This includes all areas on either side of Tundra Communities Trail and its terminus at Toll Memorial. Alpine View Trail (Trail to Nowhere) is closed for restoration.
A two-option timed entry vehicle permit system has been put in place for the entirety of Rocky Mountain National Park from mid-May through the end of October.
This timed entry vehicle permit system has been enacted due to visitor crowding and congestion within Rocky Mountain National Park, which has led to increased negative impacts to visitor and staff safety, resource protection, visitor experience, and operational capacity.
Traction Laws
During storms or when other dangerous driving conditions exist, park roadways may be closed to public travel or prohibited to use thereof, unless motor vehicles are either:
Four-wheel drive or all-wheel drive vehicle equipped with any tires with a tread depth at least 3/16 inches.
Any vehicle equipped with winter tires, all-weather tires, or tires with a “mud and snow” designation from the manufacturer with a tire tread depth of at least 3/16 inches.
Any vehicle equipped with tire chains, cables, or a state-approved traction control device.
Such prohibition or restriction of use shall be effective when signs, including temporary or electronic signs, giving notice thereof are erected upon such portion of said roadway, and it shall be unlawful to proceed in violation of such notice.
Any person who operates a motor vehicle in violation of the restrictions where the result of the violation is an incident that causes the closure of a travel lane in one or both directions, or causes damage to government or personal property, or if the vehicle is involved in a motor vehicle collision, shall be found in violation of 36 CFR § 1.5(f).
Compliant devices must be listed on the Colorado Department of Transportation (CDOT) Approved Products List
36 CFR § 1.6: Permits

Artificial or Natural Means of Attracting or Disturbing Wildlife
All park areas are closed to the use of elk bugles, varmint calls, audio attractions, or other artificial or natural means of attracting or disturbing wildlife, including rattling antlers or verbal imitations.
Wildlife Protection
To assist in avoiding wildlife habituation, protect wildlife from injury or death, minimize and prevent visitor injuries because of preventable wildlife encounters, and provide a means to assist park staff for determining acceptable wildlife viewing opportunities, the following activities are prohibited:
Willfully approaching, remaining, viewing, or engaging in any activity within 300 feet (100 yards) of wolves, 120 feet (36 yards) of moose and black bears, and 75 feet (23 yards) of all other wildlife, including nesting birds; or within any distance that disturbs, displaces, or otherwise interferes with the free unimpeded movement of wildlife, or creates or contributes to a potentially hazardous condition or situation.
Failure to remove oneself to prescribed distances during inadvertent, accidental, casual or surprise encounters with wildlife.
Failure to comply as directed by NPS staff engaged in administering wildlife management operations or managing wildlife viewing opportunities.
The prohibitions in this paragraph do not apply to persons who are in compliance with written protocol approved by the Superintendent; in accordance with the terms and conditions of a permit from the Superintendent or park personnel acting within the scope of approved management activities.
(d) The Superintendent may establish conditions and procedures for transporting lawfully taken wildlife through the park area. Violation of these conditions and procedures is prohibited.
Retrieval of Game
Conditions for retrieval of legally hunted and wounded wildlife which enters the park:
Under no circumstances may a hunter pursue and shoot wildlife in the park.
Hunters must contact the park immediately if they wound an animal and it enters the park.
If an animal dies inside the park as the result of being legally shot and wounded outside the park, a park ranger will determine if the animal carcass can be tagged and removed from the park by the hunter.
If a wounded animal enters the park, the hunter may be required to show a park ranger the location outside the park from which the animal was shot.
Hunters must present their hunting license, carcass tag, and driver’s license to a park ranger upon request.
Hunters will be responsible for the removal of the animal as directed by a park ranger. In most cases, the entire animal must be removed from the park. In cases where the animal is field dressed within the park, no part of the animal will be left within 200 yards of a trail, foot path, water source, roadway, parking lot, campground or other developed area.
Transportation of Game
Wildlife legally taken outside the park in accordance with Colorado hunting laws and regulations, and properly tagged and identified, may be transported through the park via the following:
U.S. Highway 34 and U.S. Highway 36.
Hunter Access Corridors, located at Twin Sisters Trail, North Boundary Trail via Cow Creek Trail, Bowen Gulch/Continental Divide Trail, Baker Gulch Trail, and Holzwarth Historic Site Access Road.
Commuter Hunter Access Corridors: Columbine Lake Road (County Road 49) and Sun Valley Road (County Road 491).
