Mystery Bay Marine State Park
All but hidden on the west side of Marrowstone Island, Mystery Bay State Park offers a great escape for visitors arriving by land or by water. Boaters can dock or lay anchor and stroll along the grassy and gravelly shoreline or enjoy the inlet's pristine waters.
Take along a kayak or paddleboard, shellfish harvesting buckets (and permits), or scuba gear for a day of recreation. Take in views of the Olympic Mountains from one of six unsheltered, first-come, first-served picnic tables. Cook up those oysters and clams in one of three fire rings, (fires allowed during daylight hours) and enjoy an island sunset before heading to your boat or to your campsite at nearby Fort Flagler State Park.

Historical information
Mystery Bay falls within the traditional territory of the Chemakum, a small tribe that had a permanent village in Port Townsend, but used Mystery Bay for its abundant clamming. During the early 1800s, the Chemakum population diminished abruptly through war or disease, and their western neighbors, the Klallum came to embrace the area.
Marrowstone Island's main settlement, Nordland, was settled in the early 20th Century. During that time fruit trees were planted on the present-day site of Mystery Bay State Park Property, which suggests farming once took place on the land.
Mystery Bay was acquired by Washington State Parks from the Washington Department of Natural Resources in 1972.
