Caye Caulker.

Caye Caulker is a five-mile limestone island off the coast of Belize defined by a car-free, laid-back pace and a strict "go slow" mantra. Divided in two by a narrow channel known as The Split—a popular gathering spot for swimming and seaside drinks—the island features sandy lanes navigated only by foot, bicycle, or golf cart. Because it sits just inside the Mesoamerican Barrier Reef, the island is a premier launchpad for marine adventures. Snorkeling trips depart daily for Hol Chan Marine Reserve and Shark Ray Alley to swim with nurse sharks and stingrays, while tarpon and seahorses can be spotted right from the local docks. With its wooden buildings, open-air eateries, and lack of mega-resorts, Caye Caulker retains a bohemian, barefoot charm that prioritizes the water over high-end luxury.
