The name "Mystery Bay" derives from smuggling activity on the island during Prohibition days when transporting booze from Canada was a profitable and somewhat honored occupation in northwest Washington. The harbor between Marrowstone and Indian Islands was one refuge used by smugglers to evade Coast Guard vessels who consider the disappearance of smugglers in the area "mysterious" and so the bay's name was born.

Summer: 6:30 a.m. to 10 p.m. Winter: 8 a.m. to 5 p.m. The park is open year-round for day use only.
