Appalachian Mountain Club

The Appalachian Mountain Club (AMC) is the oldest outdoor group in the United States. Created in Boston in 1876 to explore and conserve New Hampshire's White Mountains, it now expands throughout the Northeastern United States with 11 chapters stretching from Maine to Virginia. In 2024 AMC reported 65,729 people connected to the outdoors through a mix of outdoor recreation, particularly hiking and backpacking, with a focus on environmental activism. Additional activities include cross-country skiing, whitewater and flatwater canoeing and kayaking, sea kayaking, sailing, rock climbing and bicycle riding. The club has about 4,400 volunteers, who lead roughly 5,000 trips and activities per year. The organization publishes a number of books, guides, and trail maps.
