Maroon Bells–Snowmass Wilderness, Protected wilderness area in Gunnison and Pitkin Counties, Colorado, United States.

Maroon Bells-Snowmass Wilderness is a protected landscape in the Rocky Mountains spanning two Colorado counties with diverse terrain. It contains mountain peaks, alpine lakes, coniferous forests, and open meadows across varying elevations.

The Maroon Bells–Snowmass Wilderness was established in 1980, when Congress designated 181,535 acres in the Gunnison and White River national forests as a U.S. Wilderness Area. The protected land lies in the Elk Mountains of central Colorado and takes its name from the Maroon Bells peaks and Snowmass Mountain.

The Ute people maintained deep connections to this land for generations, using its resources and natural features in their daily lives. Visitors walking through the wilderness can still sense this historical relationship with the landscape.

Visitors should make advance reservations during busy periods and check permit requirements before arriving. Summer through early autumn is the best season for hiking when trails are snow-free and accessible.

Within the wilderness are seven of Colorado's fourteeners and nine passes above 12,000 feet (3,700 m), along with 100 miles (160 km) of trails. The area covers 181,535 acres (734.65 km2) in the Elk Mountains of central Colorado.
