On a busy day in summer, maybe six parties will fill out the trail register at the Avalanche Peak trailhead, so you won't have a lot of company on this hike. Yet many say it's one of the best-kept secrets in the park. Starting across from a parking area on the East Entrance Road, the difficult 4-mi, 4-hour round-trip climbs 2,150 feet to the peak's 10,566-foot summit, from which you'll see the rugged Absaroka Mountains running north and south. Some of these peaks have patches of snow year-round. Look around the talus and tundra near the top of Avalanche Peak for alpine wildflowers and butterflies. Don't try this trail before late June or after early September—it may be covered in deep snow. Also, rangers discourage hikers from attempting this hike in September or October because of bear activity. Whenever you decide to go, carry a jacket: the winds at the top are strong.
