On the shores of the Salish Sea, Padilla Bay National Estuarine Research Reserve protects one of the most extensive tidal eelgrass meadows on the Pacific coast. This shallow, nutrient-rich bay is a critical stopover for migratory birds, a nursery for salmon and Dungeness crab, and a living laboratory where NOAA studies estuarine health. The Breazeale Interpretive Center lets you explore aquariums and hands-on exhibits, while the upland trail and boardwalk offer sweeping views across the mudflats to Mount Baker. Paddlers glide through serene waters, surrounded by eagles and herons.
Best season — Spring through fall offers peak bird migration and the calmest paddling conditions.
