Fort Casey black & white

Fort Casey Historical State Park on Central Whidbey Island is a 999-acre marine camping park with 10,810 feet of saltwater shoreline on Puget Sound (Admiralty Inlet). It includes Keystone Spit, a 2-mile stretch of land separating Admiralty Inlet and Crocket Lake. Constructed in the late 1800s, Fort Casey was equipped for defense and used as a training facility up to the mid-1940s. The fort houses a pair of rare 10-inch disappearing guns. From the Admiralty Head Lighthouse, with its own interpretive center and gift shop, to the catacomb-like bunkers and batteries, this historic military fort near Coupeville makes for a memorable day trip.
