Winter Conditions at Caste Rock State Park

Winter conditions exist on the trails at Castle Rock State Park.

All trails currently OPEN, but please keep in mind the following:

  • Please check with staff at the Entrance Station to see if your planned route is safe and passable.
  • Expect to find down trees. You will need to climb over, around, or under them. If you cannot get safely past down trees, you will need to turn back. You are responsible for gauging what you can safely cross. When in doubt, TURN BACK! 
  • Trail conditions are always changing, so please be aware that you may come across blocked trails that we do not know about. Please be prepared to turn back. As always, when in doubt, TURN BACK!
  • During the Winter, wet roads and trails, down trees, and other obstructions can delay rescue. Please plan ahead with warm cloths, flashlights and other emergency supplies in case you are trapped in the backcountry overnight.


Due to damaged to the water system at the Castle Rock Trail Camp, there is no water available at this time. 

All campers and hikers will have pack in all of the water they will need for their trip. 

The only potable water available in Castle Rock State Park is at Waterman Gap Trail Camp in the southwest corner of the park.

We are working to fix the problem as quickly as possible but the system will be out for the foreseeable future.

Thank you for your understanding as we work to fix the problem.  

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
