The standard route up Quandary Peak is a trail hike (class 1), starting from a trailhead about 1 mile (1.6 km) north of Hoosier Pass on the east side of the peak. Hence it is a popular fourteener to climb because of the relatively easy ascent and its proximity to Denver and Breckenridge. Quandary Peak is also popular with backcountry skiers and snowboarders. The gentle ascent makes for an easy climb from the east with less danger from avalanche than on many other fourteeners. The other slopes of the peak are steep and appeal to expert backcountry skiers. One such steep ski mountaineering route is the Cristo Couloir.
