Walking on the Caribbean seafloor is easier than you might think. Sea Trek's specially designed helmet lets you explore the underwater world without scuba certification or previous diving experience, while keeping you dry from the chin up so even prescription glasses can be worn comfortably. After a short boat ride to the Sea Trek underwater park, you'll descend to a maximum depth of 20 feet for a guided walk past shipwrecks, historic cannons, and the sunken Odyssey submarine. Tropical fish and coral surround the route, with fun photo stops at the Pirate Jail and King Neptune Café before returning to the surface to snorkel, swim, or simply relax.
