Looking for an unforgettable underwater experience without getting wet? Step aboard the Nautilus Semi-Submarine for a comfortable, air-conditioned journey through Grand Cayman’s vibrant marine world. Gaze through large viewing windows as you cruise past haunting shipwrecks and colorful coral reefs, brought to life by a knowledgeable narrator who shares the stories behind these underwater wonders. When the vessel reaches the reef, a diver will enter the water for a fun and interactive fish-feeding show, circling the sub to ensure everyone gets great photo and video opportunities. After your journey beneath the surface, return to the cruise port or enjoy some free time shopping in downtown George Town.
