World-famous Bathhouse Row, consisting of eight turn-of-the century structures, lies within the National Park and is supervised by the Park Service. Only one of the bathhouses, The Buckstaff, remains in operation. However, another bathhouse, the Fordyce, has been converted into a museum to give tourists a glimpse into the fascinating past of the city. The federally supervised natural thermal waters are also used for thermal bathing at several downtown hotels, health spas and the Arkansas Rehabilitation Center. The water is available free for drinking at several fountains in the downtown area.
