Greenhorn Mountain Wilderness

Greenhorn Mountain Wilderness is a 23,116-acre federally protected Wilderness Area in Colorado, managed by the Forest Service. The landscape is primitive backcountry designated for non-motorized recreation and solitude. Hiking and backpacking are the primary ways to experience this remote terrain, where you'll encounter the kind of isolation and untracked country that defines true wilderness.

Access requires leaving vehicles behind—no roads, motorized travel, or mechanized equipment are permitted. This is genuine backcountry: you'll navigate on foot, camp without facilities, and travel under your own power. The Forest Service manages the area under strict wilderness rules, which means Leave No Trace principles are not just recommended but essential to preserve the landscape for future visitors. Plan for self-sufficiency, carry all water and supplies, and expect no maintained infrastructure.
