From 1928 to the late 1950s, good times were assured on Palm Island, a gated public island in Biscayne Bay reached only via the MacArthur Causeway. There some of Miami Beach’s most famous casinos, nightclubs, and one of the country’s most notorious mobsters, Al Capone, could all be found.

Capone supposedly brought gambling and plenty of illegal liquor with him, and the Palm Island Club was a place to enjoy both while the red-plush Lou Walters’ Latin Quarter nightclub was the place to see Moulin Rouge-style revues. These days Palm Island boasts palm trees, houses, and a playground. Capone lived in a Spanish-style mansion, originally built by beer baron Clarence Busch, which still stands, as do many original homes.

Lots range from 6,000 to 13,000 square feet, and houses range in price from $2.5 million to $19 million. Prices are less, of course, if you’re on the dry side.  Across a short bridge is slightly smaller Hibiscus Island, featuring smaller lots and the occasional $20-million-dollar mansion. Hibiscus also has the Miami Beach Rod & Reel Club, inhabiting a building that was once a nightspot known as Club Lido.
