Twin Harbors State Park Campground is the largest campground located along Washington's South Beach, and it is open year-round.
Divided on both the east and west side of Highway 105, the campground is comprised of 219 tightly-spaced tent and car sites, 42 electrical and water hook-up sites that are compressed into a small, orthogonal RV park area, two yurts, four walk-in sites, and one large group site that features its own picnic shelter and restrooms that can accommodate up to 60 people. Other features include numerous plumbed restroom and shower facilities and a kitchen shelter that includes a refrigerator, a stove, a sink, electrical outlets, and a wood burning fireplace.
The east side of the campground is characterized by well-shaded campsites under a forest of Sitka spruce, Douglas fir and western hemlocks; the east side has no direct access to the beach. Campsites 135, 140, 147, 148, 151, and 153 are larger sites that are located on the east side of Highway 105. The campground's west side has direct access to the beach and receives much more daylight than the east side, but it offers little privacy between campsites.
Note: Due to spatial constraints, large RVs are better suited for Grayland Beach State Park Campground, located 4.5 miles further south. The majority of the campground's east side is closed during the winter months and off season, while the west side adjacent to the beach is open-year round. The kitchen shelter can be reserved by calling 888.226.7688.
