Fodor's Expert Review Reef HQ Aquarium

Come eye-to-eye with sharks, rays, giant trevally, and green sea turtles at the Reef HQ Aquarium. It houses a 200,000-gallon predator tank, a hands-on discovery lagoon, and a vast aquarium, open to the elements. The main oceanarium is populated with 120 species of hard and soft coral, as well as sea stars, spiky urchins, sponges, and more than 150 species of tropical fish. There's also a 20-meter (65-foot) Perspex underwater walkway. Time your visit to coincide with the aquarium's daily predator dive show (10:30 am), twice-daily turtle talks (noon and 3:30), guided tours, or thrice-weekly shark feeds (2:30 on Tuesday, Thursday, and Sunday).
