    Discover more about Castle Rock State Park

    Castle Rock State Park, nestled in the Santa Cruz Mountains, offers a diverse landscape of sculpted sandstone, redwood forests, and sweeping views. Established in 1968, the park spans over 5,300 acres and provides a natural escape near the bustling Silicon Valley. The park's unique sandstone formations, created from submarine fan deposits millions of years ago, are a major draw for rock climbers. Hikers can explore over 34 miles of trails, including the popular Saratoga Gap Trail, which offers stunning views of Monterey Bay and the San Lorenzo Valley. The Skyline-to-the-Sea Trail also passes through the park, connecting it to Big Basin Redwoods State Park. Castle Rock's history is intertwined with the Ohlone people, who used the area for sustenance and spiritual connection. In the 20th century, conservation efforts by individuals like Dorothy and Russell Varian, along with organizations like the Sempervirens Fund, helped preserve the land for future generations. Today, the park continues to be a sanctuary for both people and wildlife.
