AMC maintains numerous popular backcountry campsites in New Hampshire's White Mountains, Maine's Mahoosuc Mountains, and in the Berkshires of western MA, most of which are located along the Appalachian Trail, under a cooperative agreement with the U.S. Forest Service and the Maine Bureau of Parks and Lands.

AMC also offers backcountry sites in Maine's 100-Mile Wilderness region through the KI-Jo Mary Multiple Use Forest, as a service of the Maine Woods Initiative.

These campsites help conserve the backcountry environment by concentrating already high overnight use in designated areas.
