Did you know that CBTA is the sole source of funding for the interpretive and educational programs at Calaveras Big Trees State Park.  Support from members allows  Calaveras Big Trees Association to fulfill its mission of delivering high quality educational and interpretative programs at the Park.

Since 1974, CBTA has been able to assist in enhancing the visitor’s exploration and enjoyment of Calaveras Big Trees State Park.

Becoming a member of CBTA affords you unique benefits like seminars, workshops, trainings, special events, collaboration and so much more.  Other benefits include a 20% discount (beginning October 1st) in the Visitor Center store and the Big Tree Bulletin published three times a year.

But the greatest benefit of being a member of CBTA is knowing you are contributing to protecting Calaveras Big Trees State Park and helping others gain an understanding, awareness and appreciation of its natural, cultural and recreational resources.

CBTA was established as a 501(c)(3) non-profit corporation in 1974,  Therefore, your membership and contributions are tax deductible to the extent allowable by law.
