The National Park Service offers some advice on its website to skiers in the park:
Talk with park rangers
before you leave on any trip and get specific information on conditions. Some park areas could be closed to skiing or snowshoeing to protect wildlife.
- Plan your time generously. Include allowances for limited daylight, snow conditions, temperature extremes, and the number of people in the group, their experience and physical condition.
- Check out our maps and descriptions of ski trails in Yellowstone.
- Read the daily ski trail status (courtesy of Yellowstone Park Lodges)
- A permit is required for all overnight backcountry trips.
