Once home to the Girl Scouts' Camp Tarywood, Clarke Beach is a 9-acre park featuring fishing and swimming piers, an enclosed swimming area, restrooms (open in summer), picnic tables, paved walkways, open space, and wildlife habitat. The park was acquired by the City in 1969-1970 using Washington State marine recreation funds and was developed in 1971.
