Large coastal state park near Westport with standard and full-hookup camping, showers, a dump station, and direct trail access to the Pacific beach.
Twin Harbors State Park occupies coastal forest and dunes south of Westport. The current park page offers standard, full-hookup, and hiker/biker camping, plus cabins and yurts. Hookup sites are small and close together, with limited availability up to 35 feet; larger RVs may be difficult to place. Seasonal flooding closes the entire Eastside loop and Westside sites 232–299 from November through May 31, while other campsites shift to first-come service during parts of the shoulder season. Use the current campground map and winter schedule when choosing a site.
Twin Harbors State Park fronts a wide Pacific Ocean beach positioned between the Grays Harbor and Willapa Bay estuaries — two of the most ecologically significant coastal estuaries remaining on the Pacific Coast of the lower 48 states. The adjacent Elk River estuary provides critical rearing habitat for juvenile Chinook salmon from the Chehalis River system, one of Washington's most productive remaining wild salmon rivers, while the beach itself is one of the state's premier razor clam digging beaches. The campground sits on the Pacific Flyway's coastal route, and gray whale spouts are visible from the beach during spring northbound migration in March and April when whales pass close to the Washington coast.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
Match your rig to the current campground map instead of relying on older site totals. Hookup sites are compact, and seasonal flooding closes large sections of the campground. The Shifting Sands trail provides campground-to-beach access; check current beach and razor-clam rules before visiting.
