Discover more about Castle Rock State Park

Castle Rock State Park, a 5,242-acre wilderness established in 1968, sits atop the Santa Cruz Mountains, offering a blend of solitude, challenging recreation, and stunning scenery. The park's name comes from its iconic sandstone formations, sculpted over millennia by wind and water. These formations, known as tafoni, feature unique pits and honeycomb structures, attracting climbers and photographers alike. The park's history stretches back to the Ohlone people, who utilized the area for sustenance, spiritual connection, and resource gathering. European settlers arrived in the 18th century, followed by the Gold Rush era, which brought heavy logging to the region. Remnants of these times, like heritage fruit trees, can still be found near the park's interpretive shelter. A conservation movement in the 20th century, spearheaded by locals and organizations like the Sempervirens Fund, ensured the park's preservation. Today, Castle Rock State Park boasts over 34 miles of trails that wind through redwood forests, chaparral, and alongside streams. Popular trails include the Saratoga Gap Trail, offering views of Monterey Bay, and the short but challenging Castle Rock Falls trail, leading to a 75-foot waterfall. Rock climbing is a major draw, with the park offering routes for both beginners and experienced climbers. The park also connects to an extensive trail system, including the Skyline-to-the-Sea Trail, linking the Santa Clara and San Lorenzo valleys to Big Basin Redwoods State Park.
