Trail Description:

If it’s been awhile since you last hiked up to Twin Sisters Peak, you may want to note that the park service has moved the trailhead to a new location. To reach the new Twin Sisters Trailhead from Estes Park, drive 6.3 miles south from the intersection of U.S. 36 and Colorado Highway 7. Turn east at the old Lily Lake Visitor Center (across the highway from Lily Lake), bypass the visitor center (now closed) and continue up the gravel road for less than a half-mile. The road will dead-end at the trailhead.

There are some people that will use the hike up to Twin Sisters Peak as a warm-up hike, or to acclimate for other hikes in the park, such as the Keyhole on Longs Peak, or Hallett Peak in the Bear Lake area. However, it should be noted that Twin Sisters is a worthy destination in and of itself. The views from the summit are quite outstanding.

Shortly after starting your hike the trail exits Rocky Mountain National Park and enters Roosevelt National Forest for roughly a half-mile. After re-entering the park again, and walking almost another mile, the trail begins to ascend a series of switchbacks. Views of Longs Peak, Mt. Meeker, Powell Peak, Taylor Peak and Estes Cone will begin to emerge towards the west as you proceed higher. Once past this switchback section the trail passes out of the spruce-fir forest and into the krummholz zone. Krummholz, a German word that means twisted wood, describes the stunted and irregular growth patterns of trees found in the transition zone between forest and tundra. Shortly thereafter hikers will exit the park once again and re-enter the national forest once again.

At roughly 11,000 feet hikers will finally reach tree line, at which point you’ll have unobstructed views of Twin Sisters Peak. From here the terrain becomes progressively more rugged as you climb through steep sections of talus and scree.

The trail eventually reaches a saddle between the east and west peaks. From here cairns will mark routes to both summits. East Twin Sisters Peak, at 11,428 feet, is slightly higher than West Twin Sisters Peak, which tops out at 11,413. Near the top is a stone building, a weather vane, and a radio communications tower. There was also an old fire lookout tower that was once located here as well, but it was removed in 1977.

80-year-old woman

From the summit hikers will have commanding views of Longs Peak, Mt. Meeker, Estes Cone and the Continental Divide. While soaking in the views on our most recent hike we noticed an older woman approaching from below. Amazed by her accomplishment, we started chatting with her (see photo above) and found out that she was 80 years old! Five years before that hike, at the age of 75, she had summited Longs Peak - for the ninth time!
