McMicken Island Marine State Park

McMicken Island Marine State Park is a marine conservation area on a forested island in South Puget Sound with about 1,661 feet of saltwater shoreline. The island features a natural cove that provides protected anchorage and is surrounded entirely by water.

The park was named after William C. McMicken, who served as Washington's Surveyor General from 1873 to 1886. His connection to the region helped establish this protected area for future generations.

The marine park preserves traditional shellfish harvesting areas where visitors can gather clams and crabs according to seasonal rules. This practice connects people directly to the natural resources of Puget Sound in a way that has been passed down for generations.

The area is reached by water and features five mooring buoys for overnight stays with different fees based on vessel size. Visitors should watch tide conditions and ask about local shellfish rules before arriving.

At low tide, a natural sand bar emerges and creates a temporary walking path connecting the island to neighboring Harstine Island. This seasonal phenomenon allows visitors to explore between the two islands when tidal conditions align just right.
