This 28,000-acre mountain range, which forms the boundary between southwest Montana and Idaho, is some of southwest Montana’s wildest country. Designated as an Area of Critical Environmental Concern in 2006, it is considered an important corridor for wildlife movement, providing an east-west trending mountain range connecting the Yellowstone Ecosystem with the rest of the northern Rocky Mountains. Abundant wildlife in the Centennial Mountains include moose, elk, deer, wolverines, badgers, black bears, a wide variety of birds, and occasionally wolves and grizzly bears. A variety of waterfowl, including trumpeter swans, can be found on the adjoining Red Rock Lakes National Wildlife Refuge. About 60 miles of the 3,100-mile Continental Divide National Scenic Trail runs through the mountain range. The CDT through the Centennials is usually well-maintained, although natural events can change conditions rapidly. Several side trails provide access from both the Montana and Idaho sides of the CDT. Wildflowers are especially abundant during the mid- to late summer.

Activities include hiking, horseback riding, camping, fishing, wildlife viewing, photography. BLM lands in the Centennial Mountains are closed to mountain biking except on roads open to motorized vehicles.
