McMicken Island State Park is an 11.5 acre marine park with 1,661 feet of saltwater shoreline. It is situated in the beautiful South Puget Sound and features a pristine cove to set anchor. Visitors can enjoy the many hiking trails, viewing an active bald eagle nest and shellfish harvesting. The shellfish population is abundant and open to shellfish harvesters year round. The is a sand bar that appears at low tide and connects McMicken Island to Harstine Island.

Originally, a Swedish sailor jumped ship and settled on the island, naming the island after himself, Lundquist. However, when Mr. Lundquist attempted a legal claim on the island with the U.S. government, he was told they had no record of its existence. A surveyor was sent to record the island on U.S. maps and then gave the island his name, McMicken.
