About Us


Nautilus is an intrinsic part of Grand Cayman’s unique attractions; offering unforgettable underwater tours in the Cayman Islands. Nautilus offers adventures of a lifetime in their state of the art vessels. You can take a journey in the largest, most luxurious semi-submarine in the world and see the spectacular undersea world that surrounds us. The Nautilus glides gracefully through Caymans tropical waters … but never completely submerges. Just relax and enjoy the spacious air-conditioned underwater observatory.

Watch in awe as our experienced marine expert and narrator tells you the history and mystery of the ghostly shipwrecks, the Cali and the Balboa. At Cheeseburger Reef see colourful living corals while our divers hand-feed the fish at your window.

Take our Snorkel Tour and See for yourself!

The Nautilus Experience has broadened and we are able to offer our one of a kind Semi-Submarine ride and much more now. Grand Cayman has many highlights and tours that are must see’s. It’s tough to choose between them especially if you are only visiting for a day. So conveniently we have put together some of the best packages available for cruise ship passengers who only have a few hours of precious time to spend here.
