What You Can Expect

Atlantis Submarine Expedition - Grand Cayman

Cayman sub

Make your way to the the Atlantis Adventure Center on the George Town waterfront, then start your 90-minute Grand Cayman experience with a safety briefing followed by a 5-minute boat transfer to the Atlantis XI submarine.

On arrival, walk across the ramp and step aboard the deck of the submarine. Once you enter the air-conditioned and pressurized cabin through a large hatch, your captain will complete pre-dive checks of the vessel and begin your descent. During the 45-minute ride, you’ll reach depths of 100 feet (30 meters) while exploring the underwater world of Cayman's National Marine Park. 

Enjoy a smooth ride and find out what lies beneath the water’s surface as you peer through your large view-port. You’ll be amazed by the high visibility that allows you to see huge barrel sponges, star corals, snapper, grouper and the occasional stingray or sea turtle gliding past.

After you return to the surface, you are returned to the waterfront via the transfer boat. 

Night Option:
It's the same 45-minute submarine ride, except that you'll explore the water's depths after dark. Special lights on the submarine allow you to view nocturnal marine life, particularly predatory fish that don't usually show themselves during the day. It's a memorable and eerie experience that makes for the perfect end to a night on Grand Cayman!

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.

This was a really good trip. Our tour was very small which made it even better because we were able to move from one side to the other to see. After talking with some other people - the night trip might have been better because the sun makes the colors look faded. With that said it was still great. Would do it again if ever back in Grand Caymen.
