Wheeler Trail, Summit County
This steep, technical trail is not for the faint-hearted. The incredible high-alpine views of the Tenmile, Mosquito and Gore ranges make this run well worth the effort, however.
Distance: 11 miles
Elevation Gain: 4,843 feet (north to south)
Trailhead Info: Take exit 195 off I-70 and head south on Highway 91 towards Leadville. Turn left at the gas station and follow this road to the parking lot.
