Mystery Bay State Park

Mystery Bay State Park extends across 18 acres of coastal land, featuring 685 feet of saltwater shoreline with views of the Olympic Mountains.

The bay earned its name during the 1920s Prohibition era when the waters between Marrowstone and Indian Islands served as routes for alcohol smugglers.

Local maritime traditions continue at the park where numerous wooden sailboats remain moored at permanent docks throughout the seasons.

The park provides facilities including a boat launch ramp, seasonal marine pumpout station, mooring buoys, docks, restrooms, and drinking water stations.

The gentle slope of the beach creates an easy access point for small watercraft, while the waters support activities like crabbing and scuba diving.
