Castle Peak

Castle Peak is a mountain summit located on the border between Gunnison County and Pitkin County in Colorado. The peak rises to about 4,348 meters (14,265 feet) and features steep granite slopes with exposed rock and challenging terrain.

The peak was first explored and documented during the Hayden Expedition in 1873. This survey effort contributed to mapping the Colorado mountain ranges during the early period of western exploration.

The peak sits within two national forests where visitors walk trails and experience mountain landscapes today. Its location draws people seeking to connect with high-altitude wilderness.

Several trails lead to the summit, with Mill Castle Trail providing a direct route through varied alpine zones. The path crosses different elevations with changing vegetation and requires preparation for rapidly changing weather conditions.

Precipitation patterns shift significantly throughout the year, creating distinct climbing conditions at different times. Summer offers mostly clear access to the upper slopes, while spring and autumn bring snowfields that alter the route and difficulty.
