Twin Harbors State Park boasts plenty of shoreline along the Pacific Ocean, a plethora of activities for every RVer, and a campground with almost 300 campsites. Located four miles south of Westport, Washington, Twin Harbors State Park is dissected by Washington Route 105, which runs north to south through the park. The 172-acre park is a favorite spot in the summer for family reunions and offers a lively atmosphere while camping. The park was created in 1937 when the state of Washington began to acquire land that was once a training ground for the U.S. Army. The last of the military structures were removed in the 1970s.
Twin Harbor State Park was once home to the Willapa Chinook, Lower Chehalis, and the Willapa Hills tribes. In 1866 the three tribes were bunched together to form the Shoalwater Bay Indian Tribe. The tribes survived for centuries on hunting, fishing, and gathering various foods from the area such as shellfish. Today, the tribe is located on a 335-acre reservation that is east of the park.
Twin Harbor State Park offers a natural playground for you to enjoy with activities that range from surfing, fishing, and hiking to beachcombing, kite flying, and relaxing on the beach.

Transportation in Twin Harbors State Park
You can access Twin Harbor State Park off of Washington Route 105 which bisects the park and the two campgrounds. If you are driving south to north from Grayland, Washington you will find an easy drive just off the coastline of the Pacific Ocean. Larger rigs will be able to make good time along the coastal prairie highway.
RVers and trailers will find driving north to south from Westport, Washington just as easy but there is more traffic congestion near the urban centers. The most challenging drive is from Laidlow and Bay City going east to west on Route 105. This drive will require you navigating a bridge that connects the two cities over the South Bay.
Once you arrive into the park, there will be plenty of congestion throughout with almost 300 campsites, plus day use areas, and large picnic pavilions for parties and family reunions. When you enter the campground area, there is one one-way road in the east campground that connects several loops and has numerous curves which are difficult for RVs and trailers that are longer than 35 feet to navigate.
The west campground is a single loop that offers easy driving and can be accessed from Route 105. You can also travel along the Schafer Beach Road which is located just north of the west campground and is accessed from Route 105. The road leads you to a day use area as well as a trail to the beach. Here you will find congestion in the summer months.
The best way for you to travel within the park is by bicycle. Remember when you are driving in the campgrounds to obey the posted speed limits. Drivers should be cautious within the campground loops where you may encounter bicyclists, pedestrians, and children playing.
