Mosquito Pass Trail Professional Guide
Detailed Trail Description from our Guidebook
"The route commences at Alma Junction, the intersection of Colorado 9 and Mosquito Pass Road (County 12), which was the junction of the railway spur to the London Mill and the main line. Special Attractions: The highest pass road in America; High historic significance; Wonderful alpine views. High-clearance 4WDs are recommended, though most stock SUVs are acceptable.
Expect a rough road surface with rocks larger than 6 inches, but there will be a reasonable driving line available. Patches of mud are possible but can be readily negotiated; sand may be deep and require lower tire pressures. There may be stream crossings up to 12 inches deep, substantial sections of single-lane shelf road, moderate grades, and sections of moderately loose road surface."
