History of Birch Bay State Park

Birch Bay State Park, the hidden gem of NW Washington, has been a popular tourist destination since the 1920s. 5,000 full-time residents live in the beachfront community and over 100,000 tourists visit the park annually.

The bay was originally home to the Semiahmoo, a small, peaceful Straits Salish tribe who shared the shoreline with the Loomi and Nordsack tribes since prehistoric times. Archeological evidence suggests this region was settled long before the first recorded explorers arrived in the late eighteenth century. The Spanish were first in the 1790s. They mapped the area and named the bay “Ensenada de Garzon”.

The British arrived right behind the Spanish, claiming the bay as British Territory. Botanist Archibald Menzies (1754 – 1842), a member of British Navy Captain George Vancouver’s famous 1792 expedition, changed the name to Birch Bay for the abundance of Black Birch that grew there.

During the 1850s, explorers and settlers traveled through the area in significant numbers on the way to the Fraser River goldfields in British Columbia. In 1871 the first communities were built around logging mills. Although the community remained mostly isolated it was not unknown. Even as early as 1890, it was a favorite destination because of the excellent clamming available in the bay, but getting there was difficult.

Access improved in the 1920s with the automobile and better roads. Beachfront homes and resorts sprang up to accommodate seasonal residents. Area growth continued through World War 2. With the addition of an amusement park in the 1950s, the Bay area’s tourism grew. In 1954 the Birch Bay State Park was established to provide recreational opportunities to area residents and its many tourists as well.

Birch Bay State Park is home to many bird and animal species. Raccoons and coyotes are abundant. Cougars, bear, and even a moose have also been known to frequent the park. In the forested camping areas expect to see some furry visitors.

Along the shoreline, you may find seals and sealions taking in the sun on the rocky beach. A frequent wildlife find is an “abandoned” baby seal on the beach. Seal pups are rarely abandoned by their moms who are probably fishing nearby. The mother seals will abandon the pups if they are touched by humans. Let park officials know the location of a lost seal pup but do not touch it or attempt to help.

Birdwatchers should bring their binoculars to observe many types of land and sea birds. On the forested trails you may see eagles, hawks, owls, and many more common land birds. Head to the freshwater and saltwater estuaries on Terrell Creek to see Great Blue Herons, egrets, and other waterfowl in the natural wildlife preserve.
