What we’re about
American Alpine Club events led by your local volunteer leaders in Northern Sierra, USA.
Welcome to the AAC Northern Sierra! We’re a community of climbers, mountaineers, and outdoor enthusiasts based in the Northern Sierra Nevada—covering the Northern regions of the Sierra Nevada and the surrounding mountain regions. Our goal is to bring together people who love the vertical world, from cragging and bouldering to alpine adventures and backcountry missions. We host meetups, skill-building events, and casual gatherings to connect local climbers, share knowledge, and celebrate our shared love of the mountains. Whether you’re new to the area or a long-time local, you’re welcome to join us!
