Stuart IslandAbout Stuart Island
Stuart Island is the westernmost of the ferry-less outer San Juan Islands, lying just short of the Canadian maritime border in Washington State. A marine state park encircles Reid Harbor and Prevost Harbor with docks, mooring buoys, campsites, and hiking trails, making it a favorite anchorage for boaters and sea kayakers exploring the Salish Sea.
The island's signature landmark is the Turn Point Light Station, built in 1893 on the western tip to guide shipping through busy Boundary Pass; the grounds are now part of the San Juan Islands National Monument. A small one-room schoolhouse museum and sweeping views of Haro Strait, the Gulf Islands, and passing orcas round out the island's low-key, self-reliant character.
