Fodor's Expert Review Fort Flagler Historical State Park

Take in sweeping views of Whidbey Island's magnificent bluffs and Port Townsend's Victorian skyline from what is now a 1,451-acre marine park perched at the northern tip of Marrowstone Island. This fort, along with Fort Worden in Port Townsend and Fort Casey on Whidbey Island, was constructed in 1897 as part of an "Iron Triangle" of defense for Puget Sound. Surrounded by Puget Sound on three sides, the site served as a military training center through the world wars, and still has old gun emplacements overlooking its rocky, log- and driftwood-strewn beaches. Features include a large campground, a military museum, 3½ miles of coastline, and 5 miles of hiking and biking trails; tours of the historic facilities are offered in summer. Island inlets are great for paddling around; you can book a tour or rent equipment through Olympic Kayak Tours ( 360/453–7135  www.olympickayaktours.com).
