If you’ve felt inspired or included by a Mountaineer who embodies Adventure with Purpose, make a gift in their honor and we'll send them a postcard to remind them how amazing they are! Click "Donate" above and then check the box for "add a dedication to your donation" at checkout. (Since we have many members and volunteers with similar names, a note to clarify which one you mean will help ensure we send it to the right person - e.g. "Joe Mountaineer - Foothills Scramble Leader".)

The Mountaineers has always been a fierce defender of the natural world, advocating for landscape conservation, climate action, public lands funding, and sustainable & equitable access.
We listen and tell each other the stories that shape our conservation ethic. And we speak through our actions when we give back by maintaining trails and restoring habitat.
In response to increasing recreational use of public lands, intensifying climate change, and a swiftly evolving political environment, we must strengthen our capacity to protect the outdoors for future generations.
Conservation staff lead Outdoor Alliance Washington, advocating with lawmakers and land managers on behalf of more than 75,000 recreationists to protect public lands and the outdoor experience.
Advocacy 101 and other advocacy resources equip Washingtonians to translate their passion into tangible policy outcomes for conservation and climate.
Mountaineers Books uses the power of images and storytelling to illuminate key environmental issues and spark passion for the natural world.
Since 1906, The Mountaineers has been a place for outdoor enthusiasts to come together, deepen their connection to the outdoors, and conserve our lands and waters for future generations. In 2026, donations ensure that everyone can find belonging outdoors.
We lead innovation in outdoor education. In response to growing interest in learning outdoor skills, donations allow us to invest in volunteers, teaching and gathering spaces, and expert resources. Learners are welcomed into a community of personal responsibility, collaboration, connection, fun, and friendship.
