The Coleman route is the most popular route on Mt. Baker. Begin three miles along the Heliotrope Ridge Trail, in old growth forest and climb through flower-filled avalanche chutes and over rocky moraines near the edge of the Coleman Glacier.

As the trail gains elevation the dense forest thins just before the trees peter out you arrive at the former site of Kulshan Cabin. Approximately 2.25 miles from the trailhead the path forks. The right fork leads to the Coleman Glacier climbing route.
