Cathedral Lake - 5.6 Miles Round-Trip
Cathedral Lake is located 2.8 miles from the Cathderal Lake Trailhead south of Aspen, CO. It fills a large bowl ringed by Malamute Peak (13,348'), Cathedral Peak (13,943') and Leahy Peak (13,322').
This short but feature-filled hike follows Pine Creek through aspen forests into the upper valley, where the landscape opens over treeline up to the lake. Those with time and agreeable weather can divert to Electric Pass (13,485'), the highest pass accessible by trail in Colorado:
The trail rises quickly through tall aspen stands to the Maroon Bells - Snowmass Wilderness Boundary (.72 miles : 10,425'), where the forest opens across steep, open slopes over Pine Creek.
You'll gain 820' in the first mile before moderating on a long open arc with great views up valley (1.5 miles : 11,160'). It crosses a scree field (2.05 miles : 11,555') and scales very steep switchbacks that level to the first split for Electric Pass (2.3 miles : 11,780').
The trail undulates mildly in a thinning forest to an unmarked split for Electric Pass (right), and a sharp turn (left) that drops to a footbridge over the creek (2.58 miles : 11,810'). It continues through treeline across small glades and willow patches to Cathedral Lake (2.8 miles : 11,866').
The east side of Cathedral slopes gently with good social trails around much of the lake (the west side is steep and difficult to reach). Work your way up for aerial views of the lake, and great views down valley. High points around the lake reveal more of Malamute Peak (13,348'), Cathedral Peak (13,943') and a good look at Electric Pass.
