One of the busiest ports in the Caribbean, Willemstad is the capital city of Curaçao. The city center, brimming with colorful Dutch colonial buildings that nearly touch the water's edge, has been designated a UNESCO World Heritage Site. Venture to this vibrant paradise lined with palm trees, and you'll discover plenty to see and do. Cross the Queen Emma Pedestrian Bridge to gaze upon stunning views of St. Anna Bay and the Caribbean Sea, or hit the city's many beaches to sample fresh seafood and tasty cocktails. At nearby Curaçao Sea Aquarium, activities include scuba diving and swimming with the dolphins. Head north of Willemstad's city center to explore the Hato Caves, whose limestones deposits are a favorite haunt for local iguanas.
