Mystery Bay State Park

Mystery Bay State Park is a public ocean beach in Washington, about 2 miles from the community of Marrowstone. The park has restrooms, and a fee is charged to visit. Swimming is not allowed, so plan on enjoying the shoreline from the beach rather than the water. Summer is the most comfortable time to go. July and August typically bring highs around 73°F and only about six wet days each month, according to typical averages from the nearby Port Townsend weather station. Several other spots are close by. The Cascadia Marine Trail Campsite at Fort Flagler State Park is about 3 miles away, and Lower Oak Bay Campground is a similar distance. For a walk, the Big Trees Trail and Huckleberry Hill Trail are each a little under 5 miles off.
