California Coastal Cleanup Day - Trashure Hunt 2025

Each year in September, Earth Heroes of all ages take action during California Coastal Cleanup Day. Since 2005, more than 36,000 pounds of debris have been removed from the San Mateo County coastline by more than 9,500 volunteers.

The Pacific Beach Coalition has been hosting this annual statewide cleanup since 1998, which is held on the same day as The Ocean Conservancy’s International Coastal Cleanup Day, one of the largest volunteer events around the world. We coordinate these cleanups and habitat restoration opportunities at the local level along the San Mateo County coast. All these group efforts are part of our field programs in partnership with the California Coastal Commission and San Mateo Countywide Pollution Prevention Program.

The Official Date for Coastal Cleanup Day 2025 is September 20th. Registration is open! Register online in advance.

Let’s all make trash extinct! Join us to pick up and clear away debris collecting along our beaches, parks, shoreline, creeks, parking lots, and neighborhood streets. Register online in advance to make check-in quick and easy. It also helps us know how many people to expect at each location.
