About Vashon, WA

Vashon () is a census-designated place (CDP) in King County, Washington, United States. It covers an island alternately called Vashon Island or Vashon–Maury Island, the largest island in Puget Sound south of Admiralty Inlet. Before the construction of a tombolo built in 1913, Vashon Island and Maury Island were connected only during low tide; now they are considered a tied island. The CDP's population was 11,055 at the 2020 census, up from 10,624 a decade ago. The CDP covers an area of 36.9 square miles (95.6 km2). The island is connected to West Seattle and the Kitsap Peninsula to the north and Tacoma to the south via the Washington State Ferries system, as well as to Downtown Seattle via the King County Water Taxi. The island has resisted the construction of a fixed bridge to preserve its relative isolation and rural character. Vashon Island is also known for its annual strawberry festival, sheepdog trials, and agriculture.
