Need to Know

All animals are prohibited on this trail. Due to erosion from the severe flooding rains in Summer of 2013, this is a natural restoration area. Stay on the marked trail at all times. The trail is extremely rocky for most of the distance. I saw a few trail runners making great time in both directions, so the rocks must not have been an obstacle for them. Arrive early in the morning for the best views, and parking. There are limited roadside (right side ONLY) spaces available near the trailhead. Overflow parking across from Lily Lake adds mileage to the hike.

Description

From the Twin Sisters / Lily Lake Trailhead, start hiking up the Twin Sisters Trail. This is a very popular trail/trailhead, especially in the summertime, so be ready for some crowds.

The trail begins its first series of switchbacks about a quarter of a mile from the trailhead. At this point the trail is mostly contained in a dense forest so the views of Longs Peak are fleeting.

After the first series of switchbacks, the trail levels out to a much more manageable grade and contours to the south along the mountain's western shoulder. There is a large wash just before the next series of switchbacks that offers unobstructed views of Longs and all points westward.

Gather your strength and hike through the seemingly never-ending switchback towards the summit. Eventually, you'll break out above tree line and the views will increase exponentially. Continue up the ridge to the Twin Sisters Peak Summit Spur and scramble to one of the two summits.

My view, southwest in the very near distance from 11,420' on Twin Sisters. Mt Meeker, Longs Peak & Mt Lady Washington. 09/01/2019. 1 week later, I was, Yes! Over there, looking back at this same spot, 07:30 from Chasm Lake.

14,120' elevation from the top of the western Twin Sisters Peak, looking east towards the other Twin. Wonder what they're taking pics of? Idea of scale from here, looking down the saddle up.

Natural restoration in progress, 6 years after the landslide. Take care along this part of the trail, please do not step on even the smallest blade of grass.

There are several breaks in the tree line up Twin Sisters Trail with astounding views of Longs Peak. This is 9700', looking 270 degrees SW.
