Mount Evans Wilderness, Nature reserve in Clear Creek County, US.

Mount Evans Wilderness is a protected area in Colorado covering over 74,000 acres of alpine terrain, mountain meadows, and rocky peaks. The landscape spans multiple elevations and valleys in largely untouched mountain country.

The area was designated as wilderness by the United States Forest Service in 1980. This protection status was created to safeguard the natural resources and ecological balance of the region.

The wilderness area takes its name from Mount Blue Sky, long called Mount Evans after John Evans, Colorado's second territorial governor. The U.S. Board on Geographic Names renamed the peak in 2023 at the request of the Southern Cheyenne and Arapaho Tribes, and the wilderness area still carries the old name. The Cheyenne and Arapaho were the peoples of this Front Range country before 1864.

Visitors must obtain permits before entering and follow regulations for camping, hiking, and wildlife protection. Preparation for harsh weather conditions and high elevations is essential.

The wilderness takes its name from Mount Blue Sky's former name, Mount Evans. Before the area was protected, Echo Lake Park and Summit Lake Park were bought as part of Frederick Law Olmsted Jr.'s Denver Mountain Parks system, and that effort led to a proposal for a national park overlapping much of today's wilderness.
