Sequim Bay State Park is a year-round, 92-acre marine camping park with 4,909 feet of saltwater coast in the Sequim "rainshadow," just inside Puget Sound on the Olympic Peninsula. The bay is calm and the air is dry, thus making this a popular marine park with boaters. Other features include a tennis court, baseball field, horseshoe pits, beach combing, interpretive opportunities, and the paved Olympic Discovery Trail.
