Jamaica is the Caribbean’s third-largest island. Most of its beaches are unexceptional when compared to others in the West Indies, but a number of caves and coves along the coast provide excellent opportunities for swimming and diving. In the Luminous Lagoon, near Montego Bay, the glowing organisms that give the estuary its name put on a dramatic light show every night. Dozens of waterfalls lace the island’s interior, and several botanical gardens are eminently worth visiting. Rare flora and fauna can be found in Blue and John Crow Mountains National Park, a UNESCO World Heritage site northeast of Kingston.
