The PRA was formed in 1975 to assist the park staff in providing interpretive and educational programs to the public. It is a contracted cooperating association with the California Department of Parks and Recreation and is chartered by the IRS as a nonprofit 501(c)(3) corporation. The mission of the association is to enhance and enrich the public's experience at Henry W. Coe State Park through education and interpretation.
The PRA helps support guided walks, evening talks in the visitor center, and the state park's Uniformed Volunteer Program. It also sponsors the annual Mother's Day Breakfast, the fall Tarantula Fest, and other park events.
The PRA supplies the public with free educational leaflets and publishes books and maps that are sold in the PRA bookstore at the park. As a PRA member, you receive the association's newsletter, The Ponderosa, approximately five times a year. The newsletter contains interesting articles about the park and information about upcoming park and association activities. Members receive a 15% discount on items sold by the association in their bookstore.
Annual PRA membership dues are $20 for an individual, $30 for a family or household, $10 for seniors (62 and over) and $20 for senior family membership. Memberships expire at the end of the calendar year. New memberships paid after July 1st are in effect until the end of the following year.
