State Parks looks forward to seeing Californians on trails, beaches, mountains, and the deserts on Earth Day, but asks for all to please recreate responsibly:

  • Know Before You Go: Prior to leaving home, check the status of the park unit you want to visit to find out what restrictions and guidelines are in place, and to find out if your destination may be temporarily closed. Have a backup plan in case your destination is crowded.
  • Play It Safe: Find out what precautions you should take when exploring the outdoors, especially if this is your first time visiting the State Park System. For example, make sure to dress in layers, bring plenty of snacks and water, and wear appropriate hiking shoes.
  • Leave No Trace: Leave areas better than how you found them by staying on designated trails and packing out all trash. Do not disturb wildlife or plants.
  • Download Mobile App: Visitors are invited to download the California State Parks mobile app, which allows users to download park unit maps and receive up-to-date information on any trail closures and events. Powered by OuterSpatial, the app has park information, route details, and virtual badges you can collect as you visit parks. Visitors can download the app here.
  • Don’t Doom the Bloom: If you plan on visiting a park to view wildflower blooms, make sure to first visit the Wildflower Bloom webpage for up-to-date information on the blooms and tips to safely and responsibly view them.

California’s state park system has 280 state park units, over 340 miles of coastline, 970 miles of lake and river frontage, 15,000 campsites, 5,200 miles of trails, 3,195 historic buildings, and more than 11,000 known prehistoric and historic archaeological sites.
