Fort Flagler State Park is one of five impressive military installations that were established in close proximity to protect Puget Sound from invaders during times of war. In the 1950s, all five were converted to state parks, giving the public access to thousands of near-shore acres and miles of prime coastline.
Park at the north end of the park and start your 5-mile loop hike on the stony beach, enjoying the views across to Port Townsend in one direction and Whidbey Island in the other. To your right are towering bluffs, atop which there is another trail you can take later if there is time.
Dress in warm layers, as this trail wraps around Marrowstone Point and the wind intensity may change on you. At 2.25 miles, leave the sandy beach and climb the bluff, hike around a lagoon, and eventually make your way back to your starting point. Along the way, you’ll pass a handful of historic buildings and other structures. Bring binoculars to spot bald eagles on the bluff and dabbling ducks in the lagoon.
