European-influenced Curaçao dazzles with Dutch-Caribbean architecture, hidden beaches, and spectacular snorkeling and diving just offshore. The candy-colored waterfront architecture of Willemstad, the capital, is a UNESCO World Heritage Site, and other sights—such as the floating Queen Emma Bridge and the rocky coastline at Shete Boka National Park—are well worth your while, too. But many argue that the island’s best scenery lies beneath the surface of its azure waves. Snorkeling and diving sites (including more than 65 individual dive sites around the island) are easily accessible from the shore, and boat tours out to top sites make it easy to plumb the water’s depths. Snorkel near a sunken tugboat or coral-encrusted pillars, where—if you’re lucky—you might catch a glimpse of a sea horse. You can even dip into the lagoon at the Curacao Sea Aquarium on a tour (snorkeling equipment and aquarium entry fee included) for the chance to swim among stingrays and tropical fish. If you’d rather remain on dry land, off-road tours in dune buggies or ATVs are a popular way to conquer the undeveloped western shore, which is home to historic fishing villages and challenging, hilly terrain. From Willemstad, nearby Klein Curaçao is a popular day trip—reachable by boat, the pristine, uninhabited island is ideal for a day of snorkeling and exploring.
