Birch Bay State Park
RV Guide


Surrounded by dramatic views of the Cascade Mountains and the Canadian Gulf Islands, Birch Bay State Park is the ultimate outdoor playground. The park, located just 10 miles south of Blaine, Washington, rests near the Canadian border and offers over two miles of secluded beachfront, which is perfect for relaxation and water sports. Birch Bay State Park is home to a natural game sanctuary, and it shares its shoreline with the saltwater of Birch Bay and the freshwater of Terrell Creek. Because of all of the water, there are endless options for waterside recreation here all year. Once you’ve set up your RV camp, go windsurfing, boating or fishing in the bay, hunt for crabs and clams at low tide, or hike the surrounding trails. The Terrell Creek Marsh is rare because it rolls two different water sources into the inlet, and this combination marks one of only a few remaining fresh and saltwater estuaries in the northern Puget Sound. People who are interested in the habitats of water animals should walk along the interpretive trail because the trail is ideal for immersing yourself in the birdlife and wildlife. Birch Bay State Park’s campground is perfect for an RV holiday with spacious sites, picnic areas, and even a boat ramp for launching your own watercraft. So whether you're driving a campervan, or hauling a trailer, you'll find plenty of space to park and plenty to keep you busy during your stay. In the summer, the days are comfortable and warm, while winters are cold and wet. Whatever time of year you visit, you can play a round of basketball, attend an environmental education program, or set off to explore the surrounding areas, such as the border town of Blaine or the university town of Bellingham.
