Our mission is to enrich the community by helping people explore, conserve, learn about and enjoy the lands and waters of the Pacific Northwest and beyond.


FoundersThe Mountaineers are an outdoor education non-profit teaching you skills for life beyond the city. Formed in 1906, we've been getting people of all ages outside safely and responsibly for over 100 years. We are passionate about building a community of people who are knowledgeable and care about the outdoors. We work to preserve the wild backcountry where we play for many generations to come.


The Mountaineers has a small full-time staff, but volunteers make our 100's of monthly activities happen. These passionate volunteers lead classes and activities including hiking, climbing, scrambling, navigation, first aid, sailing, photography, and skiing as well as community activities like film festivals and potlucks. Volunteer instructors are inspired by the outdoors to share their knowledge.

Our volunteer instructors are here because they want to be. Because of this we have an amazing student to instructor ratio and an unmatched culture of teamwork.


In addition to the recreational activities we pursue, The Mountaineers works to ensure that wilderness areas are preserved and protected through the actions of our Conservation, Recreation Resources and Stewardship divisions. Volunteer members track issues, mobilize members, perform trail maintenance, work with coalitions and lobby legislators (local and national)in a continued effort to protect and conserve our natural landscape.
