Quandary Peak is a fourteener in the US state of Colorado and the highest peak in the Tenmile Range, a northern extension of the Mosquito Range. It has nearly the same elevation as Castle Peak and Mount Evans. It lies in Summit County and within the White River National Forest about 6 miles (10 km) south-southwest of the town of Breckenridge.
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.
