The 280 units of the California State Park System were founded by people and organizations who deeply cared about preserving some of our state's finest natural and cultural resources for present and future generations. Many of these supporting organizations are still working to protect, maintain, and expand state parks. Some of our supporting organization web sites are listed below. You are encouraged to visit these web sites to learn more about how you can help!
