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.

Support nonprofit groups working on behalf of this park, including Sempervirens Fund, Portola and Castle Rock Foundation, Peninsula Open Space Trust, and Save the Redwoods League. Sempervirens Fund helped to create Castle Rock State Park 50 years ago and continues to support the park in many ways.
