Atlantis Submarine Expedition - Grand Cayman

Are you ready for the adventure of a lifetime? Discover the underwater world of Grand Cayman! Experience the thrill of journeying beneath the sea in a real submarine. A technological marvel, the Atlantis XI Submarine was specifically designed for underwater sightseeing excursions.

The spacious cabin is air-conditioned and is not affected by the ocean's pressure (no effect on the ears). The smooth ride and clarity of the water will amaze you as you explore Grand Cayman's Underwater Marine Park to depths of 100 feet (30 meters). This 40-minute ride is a great way to see what lies beneath the surface without getting wet!

After boarding the transfer vessel, your host will give a safety briefing and then you can kick back and relax and enjoy the sights on the 5 minute boat trip to the submarine.

Your first sight of the Submarine should be as it breaks the surface, from its previous trip. Once moored alongside, you safely board the deck of the submarine by a ramp and enter the air conditioned cabin through a large hatch. After the hatches are secured, and pre dive checks completed your descent begins.

The smooth ride and clarity of the water will amaze you as you explore Grand Cayman's Underwater Marine Park to depths of 100 feet (30 meters). Huge barrel sponges and star corals abound the reef, even the occasional stingray and turtle may pass within a few feet of your large view-port.

At the end of your tour, before returning to the dock, you'll be able to watch as the submarine again descends on another excursion, completely disappearing from your sight beneath the surface on its journey to 100 feet (30 meters).
