Castle Peak is the highest peak in Colorado's Elk Range, and is the easiest of the six fourteeners to climb. A rough four-wheel-drive road leads to around 12,800 feet, but most people start well below that. The standard route is the Montezuma Glacier, a permanent snowfield between Castle and Conundrum Peaks. An ice axe is recommended year round for this route. Many people also climb Conundrum Peak (14,060 feet), but it does not rise far enough above the saddle to be considered an "official" fourteener.
