This excursion incorporates the best features of the island both above and below the water. Travel in the Nautilus, the most luxurious semi-submersible in the world, and explore the marine paradise of Cheeseburger Reef and the ghostly shipwrecks of the Cali and the Balboa. An expert narrator and fish-feeding divers make it an adventure to be remembered. After your semi-submersible adventure, step onboard an air-conditioned bus for an island drive along the West Bay peninsula.
