Fodor's Expert Review Ft. Casey and Keystone State Park

The 467-acre Ft. Casey State Park, on a bluff overlooking sweeping views of Strait of Juan de Fuca and the Port Townsend ferry landing, was one of three forts (the "Triangle of Death") built after 1890 to protect the entrance to Admiralty Inlet from naval invasion. Look for the concrete gun emplacement and a couple of eight-inch "disappearing" guns. The charming Admiralty Head Lighthouse Interpretive Center is north of the gunnery emplacements. There are also grassy picnic sites, rocky fishing spots, waterfront campsites, and a boat launch. A Washington State Discover Pass is required ($30/year or $10/day; see  www.discoverpass.wa.gov). Once you're done exploring the park, take the ferry to Port Townsend for a quick side trip or a long lunch.
