Castle
Peak
The Hayden Survey climbed Castle Peak in 1873 and named it for the eroded rock towers crowning its summit, which recall a fortress wall. At 14,274 feet it is the highest point in the Elk Mountains and the high point of both Gunnison and Pitkin counties, and ranks ninth-highest among Colorado's fourteeners. The Montezuma Glacier, a permanent snowfield, fills the basin between Castle and its northern neighbor, Conundrum Peak.
The standard route follows Castle Creek Road into Montezuma Basin, then a Class 2 scramble up the northeast ridge — among the gentlest lines in a range known for loose, technical summits. The Aetherius Society, a British-founded new religious movement, lists Castle Peak as one of 19 mountains worldwide it considers spiritually charged, a designation with no bearing on the peak's mountaineering history.
