History of the Area
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.
A Discover Pass is required for vehicle access to Washington state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.
The park has no camping.
The park offers one single-lane launch ramp, which drops gently down the beach north of the floats.

A daily watercraft launching permit and a trailer dumping permit may be purchased at the park.

Annual permits also may be purchased at State Parks Headquarters in Olympia, at region offices, online, and at parks when staff is available.

The park also provides 683 feet of moorage and a boat pumpout station.

Moorage fees are charged year round for mooring at docks, floats and buoys from 1 p.m. to 8 a.m. Daily and annual permits are available. For more information, call (360) 902-8844.

The park provides one kitchen shelter without electricity, plus four unsheltered picnic tables, all available first-come, first-served. Drinking water is available, however the water contains high levels of sodium. Sodium intolerate persons should not consume.
