A slender necklace of landfalls off the southern tip of Florida, the Florida Keys are nirvana for anglers, divers, literature lovers, and Jimmy Buffet wannabes. The favorite of many travelers--and the biggest tourist draw--is Key West, the southernmost landfall in the continental United States, known for its sometimes raucous nightlife and sunset celebrations. But the other keys have their own unique atmosphere--from the diving capital Key Largo, to the beautiful beaches of Bahia Hondo, to exclusive (and expensive) Little Palm Island.
