Blake Island Marine State Park is a 476-acre marine camping park with 5 miles of saltwater beach shoreline. The park is reachable only boat. Once off the boat, let your boots or bicycle take you down miles of trail to the island's interior, where forest animals and birds make appearances. Or stay near the water and fish, dig for clams in season or go scuba diving. Arriving by human-powered watercraft? Hunker down in one of the Cascadia Marine Trail campsites at the west end of the island for majestic sunsets over the Olympic Mountains.
