Set in a blue cove between Bellingham and Blaine, Birch Bay State Park feels private and secluded without being far from urban life.
Stroll along the rocky beach and take in dramatic views of the North Cascades Mountains and Canadian Gulf Islands. Or head up the Terrell Marsh interpretive trail to a rare saltwater and freshwater estuary teeming with birds and wildlife, including great blue herons.
Low tide reveals a wide mudflat with a treasure trove of clams and other shellfish that can be harvested in season. Bring out the pails, shovels, mud boots and licenses, and start digging! If you prefer to swim, Birch Bay is known for its relatively warm water, and if you’d rather be on the water, the park offers excellent crabbing, windsurfing, sailing and paddling.
Staying overnight? The friendly campgrounds, basketball court and environmental education programs in summer ensure fun for the whole family. If you’re looking for a side trip, the U.S.- Canada border town of Blaine and the fascinating Peace Arch State Park are only 9 miles north, and the lively university city of Bellingham is 20 miles south. You can always spend an evening in town and return to the beachy bliss of Birch Bay.
