Belfair State Park is a 65-acre year-round campground on Hood Canal offering primitive, standard, and full-hookup RV sites plus eight reservable cabins, with excellent access for shellfish harvesting (clams and oysters) and a Cascadia Marine Trail campsite for kayakers and wind-powered watercraft.

The park features two distinct camping loops—a beach loop with waterfront access and a tree loop with forest cover—along with amenities including coin-operated showers, RV dump station, and a large grassy field.

A Discover Pass is required for vehicle access, and shellfish harvesting requires a Washington Department of Fish and Wildlife license.
