About Us

Sierra Club Washington State Chapter

With 70 years and counting under our belt, the Sierra Club Washington State Chapter is working to advance climate solutions, get outdoors, and protect Washington’s lands, water, air, and wildlife.

We work on both statewide and local issues, activating our 70,000+ members and supporters to get involved on issues they care about through our local groups and statewide committees.

Through our tried and true grassroots advocacy, long-standing outings program, and public interest litigation, we connect people to the things they care about in nature and help them better defend the natural resources they love.

The Sierra Club Washington State is a member-driven chapter of the national Sierra Club.
