General Information
Backcountry Permits
- Permits are required for all overnight stays in the backcountry.
- Due to extreme temperatures and weather conditions overnight winter trips should be attempted only by experienced and well-equipped parties.
- Permits can be arranged at the Albright Visitor Center in Mammoth, and at the West Yellowstone Visitor Information Center, and during the winter season (December 15 through March 15) at the East Entrance or Snake River Ranger Station at the South Entrance. All offices are on call, it is recommended that you call or email the Central Backcountry Office about a week prior to your arrival.
Backcountry Access
Review the roads page, learn about the non-commercially guided snowmobile access program, or read about available guiding services.
Wildlife & Pets
- Survival during the long winter is difficult for wildlife. Human contact only adds unnecessary stress. Avoid approaching or startling any animals or birds. Exercise extreme caution in bear and mountain lion country.
- With exception of service animals, pets are not allowed on trails, unplowed roads, in the backcountry, or off leash. Dog sledding and ski-joring are prohibited.
- Do not leave food unattended at any time. All food, trash, and odorous items must be properly stored (hung 10 feet above ground and 4 feet from side supports or kept in one of the installed metal bear proof boxes, or an approved bear resistant food container) whenever the items are not in immediate use. See the list of bear resistant food containers (canisters, panniers, and coolers) that are approved for use in Yellowstone.
- On March 10th, several Bear Management Areas go into effect. if you are traveling during that time make sure to familiarize yourself with these closures.
Other Notable Regulations
- Fires are not allowed in the backcountry during the winter.
- Bicycles including bicycles modified for oversnow travel, are prohibited on oversnow routes.
