California Coastal Cleanup Day
September 20, 2025

Join the Trashure Hunt! This year, California Coastal Cleanup Day will become the world's largest scavenger hunt. Special "trash" items will be hidden at cleanup sites all across the state. If you find one of them, you can redeem it for valuable prizes! Check back later in the summer for more details and to find your local cleanup location.

If you're with a company that would like to participate and contribute to the Trashure Hunt, please email eben.schwartz@coastal.ca.gov.

Participate

Participating in California Coastal Cleanup Day is easy! Follow these steps:

1. On the map above, click on the cleanup you want to attend and read the instructions. Some sites require pre-registration, others allow you to simply drop in on the morning of the cleanup. Please check the date carefully as not all cleanups will take place on September 21.
2. Sign the online waiver of liability (ENGLISH or SPANISH). Show the confirmation email to cleanup staff on the day of your cleanup. If you'd prefer to sign a paper waiver, download the ENGLISH, SPANISH, or TRADITIONAL CHINESE version and bring your signed waiver to the cleanup.
3. Gather reusable cleanup supplies from home, like a bucket and gardening gloves. Cleanup supplies, as well as liability waivers, will be available at each cleanup site if needed.
4. Show up at your cleanup site at the designated time and day. Check in with on-site cleanup staff and start cleaning!
5. Continue your efforts after Coastal Cleanup Day by participating in the Adopt-A-Beach Program, by conducting a Self-Guided Cleanup, or a Schoolyard Cleanup, any time during the year!

What is Coastal Cleanup Day?

Coastal Cleanup Day is California's largest annual volunteer event. It is an opportunity for people across the state to clean our creeks, rivers, lakes, coast, and shorelines of all kinds, to help restore our environment. Virtually every body of water in California ultimately flows to the ocean, and that water can carry a lot of trash. That's why Coastal Cleanup Day takes place throughout the state – no matter where you're cleaning, you are helping to protect our coast and ocean.

California Coastal Cleanup Day is organized by the California Coastal Commission in partnership with many NGOs and local government partners around the state. It is part of the International Coastal Cleanup, organized by the Ocean Conservancy, which is the largest volunteer event on the planet!
