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 organised grid across the bay. Willemstad's colourful colonial architecture has won its UNESCO Heritage site designation. Diving and swimming with dolphins are popular activities in the bay.
