Birch Bay State Park sits on a saltwater bay between Bellingham and Blaine, offering 167 campsites across tent, RV, primitive, and group options. Sites range from $5 to $45 per night and accommodate rigs up to 60 feet. The park includes a boat launch, interpretive trail, and direct beach access for crabbing, clamming, and tidepooling.
Mix of campground site types in a forested setting with day-use beach access: tent sites, standard sites, primitive sites and partial hookup/utility sites; one group camp is available.
Weather and SeasonsSummer brings mid-60s to mid-70s°F daytime highs and the warmest, sunniest conditions. Saltwater temperatures stay cool (roughly 50–60°F) but swimming, boating, and shoreline fishing are most comfortable from June through August. Expect full reservations and higher weekend crowds in July and August, when ranger programs run and all amenities are open. The North Loop operates first-come, first-served from mid-September through mid-May, offering quieter camping for those willing to manage cooler, wetter conditions. The park typically winterizes in late November and reopens fully by late March, though winter camping continues in the North Loop with a dedicated water supply.
Natural Features and SceneryLarge cedars and Douglas firs shade most campsites, opening onto a shoreline that mixes rocky beaches, sandy stretches, and tidal flats. The Terrell Marsh interpretive trail winds through wetland habitat where visitors spot marine life in tidepools during low tides. Meadows and viewpoint areas frame distant mountain ranges across the bay. Seasonal wildflowers appear in spring and early summer. The beach itself is the main draw: accessible, family-friendly, and productive for shellfish harvesting when biotoxin closures aren't in effect.
