This 10-acre marine park features 685 feet of saltwater shoreline and offers a spectacular view of the Olympic Mountains. This park is of primary interest to boaters, although it is reachable by car or boat.
The name "Mystery Bay" derives from smuggling activity on the island during Prohibition days. Transporting booze from Canada was a profitable and somewhat honored occupation in the remote waters of northwest Washington. Sequestered between Marrowstone and Indian Islands, Kilisut Harbor was one refuge used by smugglers to evade Coast Guard vessels. Smugglers' boats were easily hidden in the overhanging trees at a small bay near the end of the harbor. Smugglers' regular disappearance here was categorized by the Coast Guard as "mysterious," hence the name of the bay.
The park offers no interpretive activities.
