Twin Sisters Peaks

Twin Sisters Peaks is a mountain formation in the Front Range consisting of two summits at different elevations linked by a boulder-covered saddle. Both peaks offer sweeping views across the surrounding Colorado wilderness from their ridge.

The peaks were once called Lillie Mountain and Tahosa Mountain and served as hunting grounds for Indigenous peoples. They later became part of the national park landscape management system.

The twin peaks draw climbers and hikers from the surrounding area who use the place to build their mountain skills and experience the outdoors. Many visitors come here to test themselves before attempting more challenging alpine peaks nearby.

The hike takes about 4 hours and passes through exposed sections with changing weather conditions on challenging terrain. Hikers should start early in the day to navigate the area in daylight and be ready for variable conditions.

The two peaks stand separately within Roosevelt National Forest, each offering distinct perspectives on the surrounding landscape. Many visitors hike to both summits during a single visit to experience different viewpoints.
