Get Involved

Visit Castle Rock State Park. If you’ll be coming here or to other California state parks frequently, buy a state parks pass—an excellent way to save money and support state parks. 

Volunteer your time to assist visitors and protect the park. To find out about opportunities in Castle Rock and nearby Portola Redwoods State Park, contact Portola and Castle Rock Foundation. For a broader look at volunteering in California state parks, email volunteer.inparksprogram@parks.ca.gov or try this web page.  
   
Support nonprofit groups working on behalf of this park, including Portola and Castle Rock Foundation, Peninsula Open Space Trust, and Save the Redwoods League. On the League’s website, you can learn about other ways to get involved in redwoods protection—including taking a pledge, entering a photo contest, or becoming a citizen scientist.
