The Greenhorn Mountain Wilderness now contains a total of 22,858 acres and is managed by the U.S. Forest Service. All of the wilderness is in the state of Colorado.
Public land becomes wilderness through legislation passed by the United States Congress in the form of public laws. For the Greenhorn Mountain Wilderness, this process began in 1993 when 22,040 acres were designated by Public Law 103-77.
The Greenhorn Mountain Wilderness is part of the 106 million acre National Wilderness Preservation System. This System of wild lands contributes significantly to the ecological, economic, and social health of our country. Wilderness provides clean air and water, a shelter for endangered species, sacred places for indigenous peoples, a living laboratory for research, and a classroom for exploring personal values while experiencing risk, reward, and self-reliance. In wilderness, you can enjoy challenging recreational activities like hiking, backpacking, climbing, kayaking, canoeing, rafting, horse packing, bird watching, stargazing, and extraordinary opportunities for solitude.
Unless otherwise specified, no motorized equipment or mechanical transport is allowed. This is true for all federal lands managed as designated wilderness.
