A Colorado backcountry classic, Four Pass Loop travels around the Maroon Bells-Snowmass Wilderness area over four mountain passes that exceed 12,000 feet. The loop extends for a total of 27 miles and includes more than 8,000 feet of elevation gain. The route is a grand tour through meadows, valleys, alpine lakes, streams, and wildflowers. Wildlife is abundant as black bears, moose, mountain goats, elk, deer, porcupines, and a variety of birds all call the White River National Forest home.
