Atlantis Adventures St. Martin Seaworld Explorer Semi-Submarine

Atlantis Adventures Submarines Seaworld Explorer Semi-Submersible St. Martin

Create lifetime memories aboard St. Martin's only semi-submersible, in the comfort of our cruising underwater observatory.  Young and old alike will enjoy this wonderful opportunity to observe and learn about the remarkable varieties of tropical fish and coral in their natural habitat. 
Your knowledgeable marine guide will tell you all about the wonders you will be taking in throughout your tour.  Learn about the delicate ecosystem of reef development and watch in awe as your experienced scuba diver hand feeds the fish - bringing them alongside your own large observation window.
Atlantis has carried hundreds of thousands of happy guests on our semi-submersible tours in St. Martin, and over 10 million guests on our various tours throughout the Caribbean, Hawaii and Guam. 
It's the perfect family activity!  Our tour in St. Martin includes a short, scenic coastal cruise that takes you to Creole Rock, where our scuba diver escorts you on the undersea exploration of a lifetime.  You'll see the stunning sea life and colorful tropical fish - so close you'll feel as if you can just reach out and touch them.


Your adventure begins in Grand Case, a quaint, unspoiled fishing village on the French side, famous for it's idyllic bay and delicious restaurants. Here our friendly crew will welcome you aboard the Seaworld Explorer a state of the art semi submarine developed for use on the Great Barrier Reef in Australia. Enjoy the scenic cruise through the harbor to the unique geological formations of Creole Rock.

Now it's time to discover the undiscovered St. Martin! The vessel does not submerge, you descend into the hull of the vessel and sit in air conditioned comfort five feet below the surface, observing underwater gardens, coral reefs and colorful fish through large, clear glass windows. As you marvel at this paradise beneath the waves, our diver swims by your window surrounded by schools of feeding fish (keep an eye peeled for the fascinating green and moray eels!)

Throughout the trip, our knowledgeable marine expert provides an informative and entertaining commentary. On the return trip to shore, our crew will serve you a complimentary drink, which you can enjoy along with the magnificent view of Creole Rock and Grand Case Bay.
