Three Sisters Park

Bouldering in Three Sisters Park

Three Sisters Park sits at around 2350 meters in Evergreen, just west of Denver in the foothills of Colorado's Front Range, and it's one of the most pleasant low-key bouldering venues in the state. The climbing happens on Silver Plume granite — bullet-hard Precambrian rock weathered into clean domes and outcrops — set inside a mature ponderosa pine forest that keeps things shaded and peaceful. The main sectors include The Eggs with a friendly spread of easy and moderate problems, the Work and Play Area for solid mid-grade classics, and Brother's Lookout when you want harder lines; further afield, Gilligan's Island, Pirate's Cove and Tortuga add more quality blocks with their own character. Styles lean toward crimpy faces, technical slabs and a few steep features, and the park works well for both beginners learning to move on granite and stronger climbers looking for something fresh near Denver.

The altitude and shade mean Three Sisters is comfortable well into summer, while spring and autumn are the prime seasons for the best friction. Winter days can work too when the sun is out and the snow has cleared. Access is straightforward: official parking at the trailheads in Alderfer/Three Sisters Park, then short to moderate walks through the forest to reach each sector. Fixed protection is not permitted in the park, so pads and good spotters are essential. Bouldering in Three Sisters Park offers a quiet, woodland feel that contrasts with the more exposed Front Range scenes closer to Boulder or Golden, and it's well worth a day or two for anyone climbing in the Denver area.
