Fort Casey State Park is a 467-acre marine and camping park with a lighthouse, sweeping views of Admiralty Inlet and the Strait of Juan de Fuca, and 2 miles of saltwater shoreline on Keystone Spit adjacent to the Keystone to Port Townsend Ferry landing.
The historical park was originally built with gun emplacements (with 4 gun batteries still on display), ammunition depots, and other military fortifications to guard the entrance from the Strait of Juan de Fuca into Puget Sound.
The bulk of the park is located on top of steep bluffs that continue to erode onto a 1.5-mile gravel beach. The upland portion of the park is heavily wooded and contains Admiralty Point Lighthouse and Interpretive Center, the original gun emplacement structures, ammunition depots, viewpoints, and the historic 1890s era military garrison post.
The north portion of the property that includes the fort barracks, officer’s quarters, and other buildings is presently owned by Seattle Pacific University (SPU). SPU operates youth soccer and other activity camps during summer months and school vacation holidays.
North park amenities include 1.8 miles of hiking trails and interpretive activities within the gun battery and adjacent military garrison post. The park also provides a designated remote-controlled glider area and parade field popular for kite flying. The lighthouse and interpretive facility is open on a seasonal basis.
The park provides 35 standard campsites with 1 restroom and 1 shower facility on a year round basis next to the Keystone Ferry Terminal. Maximum site length is 40 feet.
The park provides 68 unsheltered picnic tables available on a first-come, first-serve basis.
Keystone Jetty – the south portion of the park adjoins Keystone Harbor and is leased to the Washington State Ferry system for the terminal between Whidbey Island and Port Townsend.
The jetty portion of the site provides a gravel beach, an historical viewpoint, interpretive signage, drinking water, restroom facilities, 2 saltwater boat ramps, 50 vehicle parking spaces that can accommodate boat trailers, fishing, and scuba diving access to an underwater park.
The site adjoins the original, historical railhead structure developed to support the Great Northern Railroad’s speculative (and never completed) expansion from Port Townsend.
