About Hope Island Marine State Park - Mason County

Boat access only defines a visit here, since there is no road or bridge onto the island. It sits due east of Steamboat Island near Totten Inlet, a position that places it within the protected waters of southern Puget Sound rather than facing open water. Anyone planning to come must arrive by their own vessel, as the park has no other way in.

Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
