Yosemite Association

The Yosemite Association is a not-for-profit educational organization dedicated to the support of Yosemite National Park through a program that includes membership, book publishing and sales, outdoor seminars, and visitor services. Established in 1923, the association was the first such "cooperating association" in the U.S. Our revenues are used to support education, museum, research, and environmental programs in Yosemite through donations to the National Park Service.
