A kaleidoscope of color surrounded by the blue-and-white tableau of the Caribbean, the candy-striped island of Curacao couldn’t be more gorgeous if it tried. Crowned by the UNESCO-listed waterfront of Willemstad, this Dutch island nation delivers culture and coastline. But while powdery beaches and uninhabited islands of the coast might be top draws, the best things to do in Curacao lie beneath the surface—you’ll find more than 60 world-class snorkeling and scuba diving sites teeming with moray eels, nurse sharks, sea turtles, seahorses, and more.
