The lively capital of Curacao is a welcoming, upbeat destination with two distinct historic districts divided by the lovely St. Anna Bay. Punda, site of neat, narrow streets, is crammed with shops and museums. Otrobanda, or "The Other Side," is a maze of twisting residential streets, contrasting with the organized grid across the bay. Willemstad's colorful colonial architecture has won it UNESCO Heritage site designations. Diving and swimming with dolphins are popular activities in the bay.
