The Three Sisters are the granite batholith domes above Evergreen Lake in Alderfer Three Sisters Open Space Park. The half day exciting adventure is a moderate hike with easy rock scrambling, roped climbing, and ending with a small summit climb or optional rappel descent off of the South Sister. There are great views of Evergreen, Mt. Evans and the surrounding peaks. Day generally takes four hours.  Fun stuff!!!!!  Three clients maximum for this adventure..
