Twin Sisters Hike in Colorado 2025

The Twin Sisters Peaks are located in the Front Range of Rockies, in Rocky Mountain National Park and Roosevelt National Forest. With an elevation of 11,433 ft (3,485 m), the summit offers magnificent views of Estes Park, Longs Peak, Continental Divide, and the surrounding area.

The 7-mi (11-km) trail lies through the picturesque area with alpine woods and meadows. It starts from the Twin Sisters Trailhead near Lily Lake. To get there drive on Highway 7, turn left onto Serenity Ln. and follow the dirt road through Estes Park. The first part of the hike is easy, but after a couple of miles, you'll pass the Roosevelt forest, and get into the boulder field with a few sets of switchbacks. Even though the trail is open year-round, the best season is May through October for the picturesque views and wildlife encounters.

Hikers can climb the East or the West Peak of Twin Sisters. Both require some effort due to scrambling, but the West Peak is considered to be a little easier. Hikers can have a perfect picnic with panoramic views on top before heading back the same way. Backpackers will need a wilderness permit to stay overnight in the backcountry. Another option is the Longs Peak Campground.
