      Trails in Big Basin and Butano State Parks are closed due to impacts from the CZU Complex fire in 2020.


      Big Basin is California's oldest State Park, established in 1902. Home to the largest continuous stand of Ancient Coast Redwoods south of San Francisco, the park consists of Old Growth and recovering Redwood Forest, with mixed conifer, oaks, chaparral, and riparian habitats. Elevations in the park vary from sea level to over 2,000 feet.

      The park has over 80 miles of trails. Mountain bikes are only allowed on dirt roads.
      Primary Trail Type: Cross-Country
