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.
The Mountaineers was formed in 1906 to explore the wild areas and peaks surrounding the still-young city of Seattle. Today, it is home to around 10,500 active members.
Although The Mountaineers has a small full-time staff, nearly 1,000 volunteers run most of the programs. Volunteer leaders do everything from leading trips to teaching classes to promoting their programs.
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).
It's easy to get involved with The Mountaineers. We offer trips, classes and events for all experience levels. So if you are an absolute beginner with a desire to get outside, or you are an experienced outdoor enthusiast, we have something for you. Our trips range from easy to very strenuous, with everything in between. You pick your own pace.
Members pay annual dues and most trips are free. Courses usually charge a fee, but members will find that these fees are less than those of commercial institutions, and members receive a substantial discount on classes we offer to the public.
The Mountaineers is a 501(c)(3) organization. Our Employer Identification Number (EIN) — aka Federal Tax Identification Number — is 27-3009280.
