Hope Island Marine State Park is a special place to those who live in the greater Olympia-Shelton-Hoodsport area. These communities share their treasure with the hope that visitors approach the island with a sense of wonder.

The island can only be reached by watercraft – motorized, human- or wind-powered. Located near Steamboat Island in the Squaxin Passage, Hope Island's terrain is made up of Douglas-fir, cedar, hemlock, alder and maple trees. A wealth of tasty shellfish draws bald eagles and great blue herons. The park is popular with shellfish harvesters in season.

Beach walks and hiking trails allow for sightings of land-based wildlife too. Picnickers may enjoy their bounty in a historic orchard of fruit and nut trees planted by early homesteaders a century ago.

Needing an extra dose of Hope? Tie your boat at a mooring buoy or choose a primitive campsite and stay for the night in this special place.
