Fort Casey Historical State Park

Close your eyes and imagine Fort Casey as it must have been 100 years ago, filled with eager young soldiers, officers, mechanics and staff. Stand at the Admiralty Head lighthouse or in a cliff-side bunker and scan the horizon, as the enlisted men must have done during World War I and II. 

Fort Casey, Fort Worden and Fort Flagler together were known as the “Triangle of Fire,” a trio of strategically placed fortifications defending the entrance to the Puget Sound at the turn of the 20th Century. 

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. While the guns were the height of technology in the early 1900s, improvements in warships and the advent of airplanes soon rendered them obsolete. Two additional mounted guns are also on display in their original emplacements. You can explore these batteries to your heart’s content.

So round up your family, friends and history buffs, and step back in time to Fort Casey Historical State Park. From the romantic 1903-vintage lighthouse, with its own interpretive center and gift shop, to the catacomb-like bunkers and batteries, this historic military fort is sure to ignite curiosity. 

Park Features


Fort Casey Historical State Park is a 998-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.

Automated pay station: This park is equipped with an automated pay station for visitors to purchase a one-day or annual Discover Pass.

Please note: U.S. Navy jets from nearby Naval Air Station Whidbey Island may fly over the campground at any time for several hours. Navy personnel conduct training missions at various times during the day and night. Depending on the direction of the wind, their flight pattern may put them above the park, creating noisy conditions for campers. Although State Parks cannot be responsible for the jet noise, we do share visitor concerns with representatives of Naval Air Station Whidbey.
