What better way to celebrate Earth Day than by visiting the outdoors and learning how you can help protect natural and cultural resources? California has over 200 state park and beaches that can be enjoyed this Earth Day (Saturday, April 22) and year-round to go on a hike, walk among the giant sequoias and redwoods, discover the waterfalls along the trails, get a glimpse of the wildlife or simply enjoy the breathtaking views along the coastline or mountains.
“2023’s Earth Day theme is ‘Invest in Our Planet,’ and I invite all Californians to try to invest a little more time to the outdoors,” said California State Parks Director Armando Quintero. “Get inspired and take action to make our communities, parks and planet more sustainable, cleaner, accessible, equitable and safer for all.”
On Saturday, April 22, several state parks will have activities for the public to participate in, including cleanups at Carpinteria State Beach and Old Town San Diego State Historic Park (SHP) and a BioBlitz at Castle Rock State Park. If you cannot head to outdoors, join us for a special virtual event, as staff will be livestreaming from Calaveras Big Trees, Mount Tamalpais and Prairie Creek Redwoods State Parks for a program called “Small Actions, BIG TREES: The Story of the Coast Redwood and Giant Sequoia.”

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 the 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.
