Every April, thousands of volunteers descend upon more than 300 miles of shoreline in Washington state to remove tons of trash during Olympic National Park’s Washington Coast Cleanup.

Much of the event — set this year for Saturday, April 22 — is organized and sponsored by Washington CoastSavers, an alliance of partners and volunteers dedicated to keeping the state’s beaches clean of marine debris through coordinated beach cleanups, education and prevention efforts.

Motor vehicles are not allowed on any park beach, and all litter or debris must be removed on foot. Camping in the coastal campgrounds of Olympic National Park will be free for volunteers from Friday evening, April 21, through Sunday morning, April 23. At some locations, volunteers must hike several miles to reach a beach, gather trash and then haul it back to the trailhead.

Backcountry permit fees will also be waived for volunteer participants staying overnight on wilderness beaches of Olympic National Park.
