Kopachuck State Park is a publicly owned recreation area situated on Henderson Bay in Puget Sound, about 6 miles (9.7 km) west of the city of Gig Harbor, Washington. The state park's 109 acres (44 ha) encompass over a mile of saltwater shoreline. The park provides sweeping views of sunsets, the Olympic Mountains and Puget Sound. Cutts Island, known locally as "Deadman's Island," which lies about a half-mile from the park shore, is reachable by boat. Both Kopachuck and Cutts Island are administered by the Washington State Parks and Recreation Commission.
