About

Calaveras Big Trees Association (CBTA)  can trace its roots to the original Calaveras Grove Association organized in 1926 by a group of individuals intent on preserving the historic groves for future generations. Through their efforts Calaveras Big Trees State Park was born on July 5, 1931.

The Calaveras Big Trees Association was founded in 1974 by a new group of interested people with a revised purpose:  as a private, non-profit, charitable 501(c)(3) corporation toto create, fund and deliver inspirational educational and interpretive programs, as well as inspire visitors to help preserve and protect the Giant Sequoias and all the Calaveras Big Trees State Park’s natural resources. These programs enable visitors to understand, appreciate, conserve, enjoy and explore Calaveras Big Trees State Park.  CBTA uses membership fees, donations and fundraising to accomplish this mission. Membership is open to all.  The board members are all volunteers.
