The Wilmington State Parks system, centered on Brandywine Park, is a historic riverfront park designed in the Olmsted tradition. Tree-lined paths, stone bridges and open lawns run along the Brandywine River, giving the city a green corridor close to downtown. Visitors can stroll the riverside paths, visit the Brandywine Zoo, and enjoy the plantings at Josephine Gardens. The park's classic bridges and landscaped settings make it a favorite for walking, photography and picnics. Admission is $4 for Delaware residents and $8 for out-of-state visitors on weekdays, and $8 and $16 on weekends, from March through November. It is an easy stop for anyone visiting Wilmington.
