Hot Springs is the smallest national park in the contiguous US (5,500 acres) and the most urban, Bathhouse Row, the park's protected core, runs along Central Avenue in downtown Hot Springs, Arkansas. Federal protection of the 47 thermal springs predates the National Park Service: the area was set aside as a federal reservation in 1832, the first land in US history specifically protected by the federal government. The eight historic Beaux-Arts bathhouses on Central Avenue were built between 1892 and 1923; two (the Buckstaff and the Quapaw) still operate as working bathhouses. The park has no entrance fee and no entrance gate, you can walk into Bathhouse Row from any downtown sidewalk. From I-30 the standard route is Exit 98 in Malvern, then 24 mi west on US-270.
