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.
