Fort Casey State Park and Admiralty Head Lighthouse

This park features 467 acres that command a spectacular view of Puget Sound’s Admiralty Inlet.

A coast artillery post features two historic guns on display. The park features 10,810 feet of saltwater shoreline on Puget Sound (Admiralty Inlet), and includes Keystone Spit, a two-mile-plus stretch of land separating Admiralty Inlet and Crocket Lake.

At sunset, the Admiralty House is in silhouette.

Red clouds serve as the dramatic backdrop at sunset for Admiralty Head Lighthouse.

Historic Fort Casey was once part of the nation’s maritime defense effort. Together with two other forts on Admiralty Inlet, they formed what was called the “Triangle of Death” as no invading vessel would be able to avoid the guns from all three forts.

Admiralty Head Lighthouse actually preceded the fort and was moved to make room for the fort.
