BPX 2-Day: Crater Lake from Monarch Lake TH

This difficult 15-mile trip is a beloved Colorado classic, ending at the photogenic Mirror Lake with Lone Eagle Peak's distinctive profile reflected in the still alpine waters. As one of the most popular destinations in Indian Peaks Wilderness, make sure you have the correct permits and camp only at designated sites around Mirror and Crater Lakes.

Description: Mostly flat for about 4 miles at the start, the trail ascends alongside Buchanan and Cascade Creeks offering gorgeous views of the surrounding wilderness and small waterfalls. The tranquil Mirror and Crater Lakes mark the end, sporting 12 designated campsites and stunning views of Lone Eagle Peak.
