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.
