CBTA was formed by a small group of interested people.  Their goal was to help provide financial support for the interpretive activities which would enable visitors to understand, appreciated, conserve, enjoy and explore the areas of Calaveras Big Trees State Park.

CBTA is a non-profit educational association dedicated to the interpretation of human and natural history at Calaveras Big Trees State Park, in cooperation with the California State Park System.  All contributions are tax deductible as allowed by law.
