Boulder Trails

Boulder, CO: Mount Audubon

Compared to its jagged neighbors, this 13,000-foot summit is one of the easier peaks (no technical scrambling required) to tick off in the Indian Peaks Wilderness.

From the well-signed trailhead, hike northwest on Mount Audubon Trail. The first stretch is easy going as the path climbs gently through fragrant evergreens and passes a golden meadow with intermittent views of the Indian Peaks. At mile 1.3, cross a small boulder field dotted with stunted spruce before heading above treeline.

Pikas squeak and scurry across rocks as you climb through alpine meadows and cross another rocky landslide. On cloud-free days, Longs Peak (the highest peak in Rocky Mountain National Park) dominates the northern skyline from a grassy saddle at mile 3.4. The final 0.3-mile stretch slows down the pace and ascends talus slopes to Mount Audubon. Pull out the camera and capture stunning views from Lake Granby to Winter Park to Rocky Mountain National Park before retracing your route back to the trailhead.
