Greenhorn Mountain Wilderness rises in Pueblo County's Wet Mountains

West and south of Pueblo, the land climbs into the Wet Mountains, and at their crest sits Greenhorn Mountain Wilderness. It is part of the Pike-San Isabel National Forests, managed by the San Carlos Ranger District, and Congress set it aside as wilderness in 1993. Greenhorn Mountain itself is the high point of the area.

This is a different kind of place than the busy reservoir in town. There are no big lakes and only a short network of trails, so it sees relatively few visitors. Wilderness designation also means stricter rules than ordinary forest land: no motor vehicles, no bikes, and limits on group size and how you camp. Access is by trailheads such as those reached from the Rye area and Colorado Highway 165, and the high country holds snow and weather long after town has warmed up.

Why mention it to someone settling near Pueblo: it is a reminder that real backcountry starts close by, and that the rules change once you cross a wilderness boundary. Knowing whether you are on general forest land, wilderness, or private ground matters for what you may legally do.

Before a trip, check the trailheads, current conditions, and wilderness rules with the Forest Service for the San Carlos Ranger District.
