The Mary Mountain-Nez Perce Trail traverses central Yellowstone National Park, stretching between Hayden Valley on the east and Nez Perce Creek on the west. Hikers encounter wide open meadows, forested ridges, and thermal features along this backcountry route. Because the surrounding area is prime habitat for bison and grizzly bears, visitors should exercise vigilant wildlife safety.
