Birch Bay State Park is a delightful 194-acre Washington state park preserving one of the Puget Sound's few remaining combination saltwater and freshwater estuary habitats.

The park and bay, which were named in 1792 by botanist Archibald Menzies for the area's high population of birch trees, is located approximately nine miles south of the city of Blaine in Whatcom County, stretching for over 23,000 feet along the Puget Sound and Terrell Creek shorelines.

Stunning panoramic views of the Canadian Gulf Islands and the Cascade Mountains are offered throughout the park, which offers more than two miles of public beachfront for visitors to fish, boat, crab, and clam.

A natural game sanctuary is offered at the park's northern end, with opportunities for hiking, picnicking, and overnight camping also available. Be sure to check out the Wings Over Water Northwest Birding Festival in March, 2025.
