James Island State Park is a 113-acre marine camping and moorage park with 12, 335 feet of saltwater shoreline on Rosario Strait. The park features a beautiful western view of the San Juan islands from a high bluff along the loop trail. The Wilkes Expedition named the island in 1841 to honor the earlier heroism of an American sailor, Reuben James. The federal government acquired the island and transferred it to the Washington State Parks and Recreation Commission in 1964.
