The below information is for reference only. We will continue to evaluate and adapt to changing COVID-19 guidance and adjust operations as needed.
Important Safety Notice
Effective February 5, 2021, individuals over the age of two years must wear masks, except when actively eating or drinking, in the following locations:
Masks must cover the nose and mouth and fit snugly around the nose and chin with no large gaps around the sides of the face. Masks not designed to be protective, masks with ventilation valves, and face shields do not meet the requirement.
Exceptions: CDC guidance recognizes that masks should not be worn by anyone whom has trouble breathing. Wearing masks may be difficult for some people with sensory, cognitive, or behavioral issues. If a visitor is unable to wear a mask properly or cannot tolerate a mask, they should not wear one and may be asked to leave any location where masks are required to be worn. Visitors may be asked to lower their masks briefly for identification purposes in compliance with safety and security requirements.
Roads and Construction
Most roads, except the road from the North Entrance to the Northeast Entrance, are closed for the season to automobile traffic. For current road status, check the map above or call (307) 344-2117 for recorded information. The park roads page lists current status, seasonal road opening/closing dates, as well as construction projects. The webcams provide a live look at traffic approaching the north and west entrances.
Expect delays and/or traffic pattern changes in these locations.
Spring bicycling may be permitted on park roads while they’re closed to motorized, public travel. Electric or pedal-assist bikes are considered to be bikes (as opposed to motor vehicles). They can ride anywhere bikes are allowed. Check out what is open for bicycling on the Spring and Fall Bicycling page.
Eating and Sleeping
Services are limited. The Mammoth General Store is open year-round except for Thanksgiving, Christmas, and New Year's Day. Please check out the Operating Hours page what other services are available in the Mammoth Hot Springs area.
The nearby attractions page provides links to services in surrounding communities.
Never approach animals or block traffic to view them. The animals in Yellowstone are wild and unpredictable, no matter how calm they appear to be. Always stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other animals, including bison and elk. Read more about safety in bear country.
Wildland fire danger is LOW. There are no backcountry fire restrictions. See the current fire activity page for more information.
The Natural Resource Conservation Service offers an interactive map that displays current data on snow depth, snow water equivalent, and more from SNOTEL stations in and around Yellowstone. Avalanche forecasts and other winter safety information are available from the Gallatin National Forest Avalanche Center and the Bridger Teton Avalanche Center.
Swim and Soak
Boiling River: Closed until further notice due to public health guidelines
Hiking Trails and Backcountry Campsites
Check the backcountry situation report or call the Backcountry Office at 307-344-2160 for trail and campsite conditions. Stream levels have risen in some areas with the recent rain and snow. Use caution when crossing streams.
The fishing season runs from the Saturday of Memorial Day weekend (usually the last weekend in May) and extends through the first Sunday in November.
