I visited the Aspen area to backpack the Maroon Bells Four Pass Loop, a 25 mile multi-day hike. Buckskin Pass is part of this loop, and has an incredible view on all sides. The pass is a 5 mile hike from the trailhead at the Maroon Bells Visitor Center, so it is 10 miles round trip. The hike is stunningly beautiful but also extremely strenuous, reaching an elevation of 12,500 feet at the pass. Please be careful and do not attempt without plenty of water.
