ALERT: Due to recent bear activity, bear canisters are required for all backpackers in the Maroon Bells-Snowmass Wilderness. The trail begins ascending steeply and forks to the right in about one mile. The trailcontinues through spruce, aspen and pine forests for approximately 3 miles. It then breaks out into a meadow before continuing a moderately steep climb. There are some steeper sections that require caution. Once on East Snowmass Pass, the descent to Willow Lake is via switchbacks through a steep boulder field. The last mile meanders through rolling tundra to Willow Lake.
