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. This family-friendly adventure gets you up close and personal with sea creatures like coral and sponges, colorful snapper and grouper, and maybe even a turtle! Choose a morning or afternoon tour, or go at night for a more dramatic experience.

Know More about this tour

Your Grand Cayman underwater experience starts with a safety briefing by your host and a 5-minute boat ride via transfer vessel to the submarine. Catch your first sight of the submarine as it breaks the surface of the water from its previous trip. Once it's moored alongside the transfer boat, step aboard the deck of the submarine via a ramp, and enter the air-conditioned cabin through a large hatch. After the hatches are secured and pre-dive checks are complete, your descent begins!

The spacious cabin is pressurized, meaning you shouldn't feel any effect on the ears. As you explore Grand Cayman's Underwater Marine Park to depths of 100 feet (30 meters), be amazed by the smooth ride and clarity of the water. During the 40-minute ride, find out what lies beneath the surface of the water without getting wet huge barrel sponges and star corals abound on the reef, snapper and grouper swim peacefully by, and even the occasional stingray or turtle may pass within a few feet of your large view-port.

Your tour ends with return to the surface, where you can watch the submarine descend again on another dive before you are returned to the dock on the transfer boat.

Night option:
Choose the night option to go on the same journey as the daytime tour but with the added moodiness of being underwater after dark. During this 45-minute ride, see nocturnal marine life that doesn't usually show itself during the day, particularly predatory fish. The special lights on the submarine allow you to spot these night owls without scaring them away. It's a memorable and eerie experience that makes for the perfect end to a night on Grand Cayman.

    Of all the things we did in Grand Cayman, this was hands down my 7-year-old's favorite! He LOVED being able to see all of the sea life below the surface, as well as our guide/narrator, who was very fun and humorous. We got to see thousands of beautiful fish, including blue fish, barracuda, a sea turtle, a nurse shark, and even a ship wreck! The boat operator tried to make sure each side of the sub got to see everything- he turned the sub around so both sides could see the ship wreck and nurse shark. The company was very easy to work with, too. I needed to change our reservation a couple of times and they responded right away and were very accommodating. I highly recommend this experience!

    Our Atlantis Submarine Expedition was great and all we hoped it would be. We saw lots of colorful fish, a sting ray and turtles. Would highly recommend this excursion. The guide was also very informative.

    I really enjoyed the trip. Friendly lighthearted knowledgeable staff. You watch/take-pics from the ferry as the sub rises out of the water with the previous tour. I also took a video of the sub submerging after our tour. Saw a turtle, a stingray and lots of fish. My iphone X took great photo's and video out the window. It's best to go on a sunny day - more light down below. I took a meclizine beforehand since the sub tends to bob around a little bit when at the surface. A couple nice little surprises at the end - I won't spoil it.

    The trip on the Atlantis over 100 down to see the fish, turtle, spiny lobster and coral was awesome. The narration was great too and the large port hole gave us a great view. Would love to someday do the night tour,

    I was scheduled to take this tour on my birthday, but due to high winds, it was cancelled. I was so disappointed. On my last day in Grand Cayman, I was blessed to take this tour. IT WAS WORTH IT! They really treated me nicely they gave me a t-shirt as a birthday present -- and sang happy birthday to me at 100 ft. below!!! Because of the wonderful staff of Atlantis Submarine Expedition - Grand Cayman, I will always remember my 51st birthday!!!! Awesome experience.
