About Roche Harbor
Situated on the sheltered northwestern shore of San Juan Island, Roche Harbor is famous for its picturesque resort marina and close proximity to Garrison Bay Tidelands and Westcott Bay Shellfish. Surfing and traditional ocean tide pooling are nonexistent in these calm waters, but the area is a world-class destination for shell fishing, renowned for cultivated and wild oysters, Manila clams, and sweet mussels. Monitoring tide predictions is vital for shell fishers and boaters alike; low tide exposes the expansive tidal flats in Westcott Bay and Garrison Bay necessary for digging clams, while tracking tide shifts ensures safe, easy navigation through the narrow harbor channels.
