Hope Island State Park is a 106-acre marine camping park on the western side of the state in Mason County, Puget Sound. This quiet island is reachable only by boat. Covered with old-growth forests and saltwater marshes, the park features a beach one-and-a-half miles long. The park offers several campsites, attractive beaches and a trail across the island. The island is forested with occasional meadows and rock outcroppings. One-and-a-half miles of beach and two miles of hiking trail attract boaters to this small, quiet island.

Hope Island was named by Commander Charles Wilkes for one of his crew in 1841. Wilkes was engaged in the mission of charting Puget Sound.
