About Oak Bay Marine Refuge

Oak Bay Marine Refuge is a protected marine sanctuary in Washington state offering rich underwater ecosystems and opportunities for kayaking, wildlife viewing, and coastal exploration.

Wilderness Landscape & Natural Heritage

Oak Bay Marine Refuge spans approximately 600 acres in the southern Puget Sound near Orcas Island, Washington. It is designated as a marine protected area to conserve unique subtidal habitats, kelp beds, eelgrass meadows, and diverse marine wildlife. The refuge provides critical habitat for many species including rockfish, Dungeness crab, sea stars, harbor seals, and numerous migratory seabirds. The area’s calm waters and rich biodiversity attract kayakers, snorkelers, and recreational fishers who benefit from the thriving underwater life and clear views of marine flora and fauna. The surrounding shoreline is a mix of rocky beach and forested land, part of the larger San Juan Islands ecosystem. Historically, this area has been important to Indigenous peoples for its marine resources and holds cultural significance. Visitors can enjoy guided paddling tours or explore smaller coves for wildlife observation. The refuge aims to preserve marine ecosystems while allowing low-impact recreational use. Educational programs and volunteer monitoring projects support marine science and conservation efforts. Access is primarily by boat, and there are no designated campgrounds within the refuge itself, but nearby Orcas Island offers ample accommodations and camping options. Oak Bay Marine Refuge highlights Washington’s commitment to protecting marine biodiversity and offers a serene coastal experience for nature enthusiasts and outdoor adventurers.
