Review:
Arapaho Glacier is located in Roosevelt National Forest, bordering Colorado's North Arapaho Peak. This alpine glacier was once the largest glacier in Colorado but has lost more than half of its surface area over the last century. The trail is very popular and busy. From the Arapaho Glacier trailhead the trail leads to Arapaho Glacier Overlook after 6 miles and to the Fourth of July Mine after 7.8 miles.
Two trails intersect the Indian Peaks Wilderness, first through dense forests and then through the open tundra, from where the view of the entire city of Boulder watershed is spectacular. The highest point is South Arapaho, an overlook of the Arapaho Glacier, at 13,397 feet. There is a seasonal campground at Rainbow Lakes, but campfires are not allowed. Dogs are allowed at Arapaho Glacier but must be on a leash.
