Willemstad's historic core spreads through Punda, Otrobanda, Pietermaai, and Scharloo, with the Queen Emma pontoon bridge linking the two sides of Sint Annabaai. Most central sights are walkable, though Scharloo and the Rif Mangrove Park extend the circuit. Mambo Beach, the Curaçao Sea Aquarium, and Dolphin Academy form a separate cluster southeast of the centre and are easiest to reach by car or taxi.
