Al Capone fled Chicago's heat after bloody hits, holing up in this spa town
Hot Springs, the Waters of the Underworld
« I've never seen a town with so much charm and vice intertwined. »— An anonymous Hot Springs visitor, quoted in a 1930 dispatch
Al Capone's Hidden Paradise
Hot Springs, dubbed the 'American Spa,' has attracted millions of visitors for its healing thermal waters since its designation as the first federal reservation in 1832. However, in the Prohibition era, its resort town atmosphere transformed into a discreet paradise for organized crime. Figures like Al Capone, Bugs Moran, and Lucky Luciano regularly frequented the city, drawn by its illegal gambling houses, speakeasies, and political tolerance. The Arlington Hotel, with its impeccable service and private baths, served as Capone's unofficial headquarters, providing a perfect cover for his less honorable activities.
The city became a major hub for illegal gambling and bootlegging, with operations extending far beyond Arkansas. Local authorities, often corrupt, turned a blind eye, allowing Hot Springs to flourish as a haven for the underworld. This climate of secrecy and permissiveness persisted until the 1960s, when concerted federal efforts finally dismantled the gambling and crime empires, transforming the city into a more respectable tourist destination, but never quite erasing the legends of its notorious past.
