Discover more about Castle Rock State Park

Castle Rock State Park, a sprawling 5,242-acre wilderness established in 1968, sits atop the Santa Cruz Mountains, offering visitors a diverse landscape of high ridges, deep canyons, and unique rock formations. The park's origins trace back to the Ohlone people, who utilized the area for sustenance and spiritual connection, and later, to European settlers who transformed the landscape through logging and agriculture. The park's most iconic features are its sculpted sandstone outcrops, formed millions of years ago and shaped by tectonic activity and erosion. These formations, known as tafoni, create a playground for rock climbers and offer unique photo opportunities. Castle Rock itself is a popular climbing destination, attracting both seasoned climbers and beginners. The park boasts over 34 miles of trails that wind through lush coast redwood forests, chaparral, and riparian habitats. The Skyline-to-the-Sea Trail, a 32-mile backpacking route to Waddell Beach, begins here. Popular trails include the Saratoga Gap Trail loop, offering views of Monterey Bay, and the short but challenging Castle Rock Falls trail, leading to a 75-foot waterfall. Castle Rock State Park is not only a place of natural beauty but also a sanctuary for wildlife. Visitors may spot deer, pronghorns, and various bird species. The park's diverse plant communities include California black oaks, knobcone pines, and high-elevation coast redwoods. Visitors can enjoy hiking, backpacking, rock climbing, and horseback riding. The Castle Rock Trail Camp provides a base for overnight adventures, while the park's amphitheater hosts events and programs.
