Visiting Castle Rock

Castle Rock State Park is a land of sculpted sandstone, lush forests, and sweeping vistas. From one of the highest ridges in the Santa Cruz Mountains, park visitors enjoy hiking, backpacking, and horseback riding. Rock climbers explore the park's caverns and rocks, including the namesake Castle Rock. Plant-lovers come for California black oaks, knobcone pines, and high-elevation coast redwoods. The park’s 34 miles of rugged trails conveniently connect to an extensive trail system that links the Santa Clara and San Lorenzo valleys to nearby Big Basin Redwoods State Park and open space preserves on the Skyline to the Sea Trail

Primitive campsites for backpackers are the only overnight facilities. Equestrians are urged to call ahead for current trail information, and smokers are advised that, due to high fire hazard, smoking is prohibited on the trails within Castle Rock State Park.
