This Wilderness is located in Colorado within the Elk Mountains and spans the White River and Gunnison National Forests. The Wilderness area surrounds the extremely popular Maroon Bells Scenic Area which is a major access point for Wilderness travel.

Advance reservation overnight permits are required for the busiest areas of the Maroon Bells-Snowmass Wilderness including Conundrum Hot Springs, Capitol Lake, Crater Lake, and the Four Pass Loop (including Snowmass Lake and Geneva Lake).
