Washington State Park

Park Information

Petroglyphs, quaint hiking shelters and incredible Ozark overlooks define the Washington State Park experience. Easy access to the Big River makes the park great for swimming or fishing. Hikers can choose from three rugged hiking trails. Buildings constructed by African American Civilian Conservation Corps stonemasons complement the park and add to its sense of history.
