Fort Casey Historical State Park
The 467-acre Fort Casey Historical 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 8-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 on Keystone Spit. A Washington State Discover Pass is required ($45/year or $10/day; see www.discoverpass.wa.gov). Once you're done exploring the park, take the nearby ferry to Port Townsend for a quick side trip or a long lunch.
