Rocky Mountain National Park: Twin Sisters

Climb 2,400 feet to twin peaks on Rocky Mountain National Park’s east side. Aspen-shaded trails and unobstructed views of Longs Peak are just two rewards of this 7.2-mile out-and-back.

Trip Tools

From the Twin Sisters Trailhead begin hiking south along a well-maintained access road. At the circular turnout near mile 0.3, veer left onto the Twin Sisters Trail and immediately begin a gradual ascent through thick spruce and pine. Unobstructed views of Longs Peak unzip at the base of several switchbacks beginning 1.5 miles from the trailhead.

Continue ascending and pay no heed to the false summits looming above. Roughly 2.5 miles into the hike, the trail breaks treeline, and 180-degree views open to the north. Peer 2,000 feet down to Estes Park and the Stanley, an historic (and haunted) hotel.

As you continue climbing, look for a tall radio tower marking the saddle between the east and western summits. From the saddle, access either peak with a quick class 2 scramble to the top. Have a picnic lunch admiring the views before turning back on the same trail.
