Pacific Beach State Park, State park along Pacific Ocean in Grays Harbor County, United States.

Pacific Beach State Park is a coastal park in Grays Harbor County featuring about 2,300 feet of sandy shoreline and flat tidal areas. The landscape provides different habitats for marine life and is used by visitors for various beach activities.

The park was established by the Washington State Parks and Recreation Commission to protect the natural shoreline. This creation gave the public access to this stretch of coast and its outdoor activities.

Clam digging, fishing, swimming and beachcombing are the activities the 2,300-foot ocean frontage is used for; the park's 17 acres sit in Grays Harbor County, and the hard-packed upper beach is also driven on. The nearby town of Taholah lies about 17 km to the north.

The park offers campsites with and without hookups, plus yurts for overnight guests. Day visitors can use picnic areas, and you should watch the tides to find the best conditions for activities.

The upper beach area with hard-packed sand allows vehicle traffic under specific conditions. This unusual use sets this shoreline apart from many other coastal areas.
