Want to explore New Providence Island’s underwater habitats without getting wet? It’s easy with a tour in a comfortable glass-bottomed boat. Operating out of Nassau’s harbor, these vessels first sail past some of the island’s most notable shorefront estates and landmarks; then they ply the translucent waters around the island, taking in aquatic gardens of elkhorn and brain coral and swirling schools of tropical fish. You can even use your dry-land camera to take photographs!
