Castle Rock State Park
Due to the catastrophic failure of Skyline Boulevard (Highway 35) south of the Castle Rock main lot, visitors cannot access the park from Black Road, Summit Road, or Bear Creek Road. It is still possible to access the Castle Rock main lot from Highway 9, Alpine Road, Page Mill Road and other points north of Castle Rock State Park on Skyline Boulevard (Highway 35). There is no estimate as to when this road will be repaired.
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.
