We’re climbers. Gym climbers and trad climbers. Sport climbers and mountaineers. Boulderers, backcountry skiers, and alpinists.
Established in 1902 by the nation's leading climbers and conservationists, the AAC promotes and preserves the climbing way of life. We support, connect, and advocate on behalf of the climbing community.
At over 25,000 strong (and growing) we are the largest community of rock-climbing, mountain-loving,outdoor-enthusiasts in the country-together supporting our shared passion and respect for the places we climb-and you belong here.
