The shallow reefs around Grand Cayman are teeming with colorful coral and schools of fish. Descend just below the surface inside the Observatory and discover an underwater adventure.

Board the Seaworld Observatory, a semi-submarine vessel specifically designed for shallow reef exploration. Sit in air-conditioned comfort just 5 feet (1.5 m) below the ocean surface as your captain maneuvers to various locations. The first stop is the dramatic shipwreck of the Cali, a steel schooner built in 1900 and sunk in 1944.

From here, your captain takes you to Cheeseburger Reef. Be sure to have your cameras ready when a diver enters the water and begins to feed the hundreds of multi-colored tropical fish right in front of your window.

Hear more tales of the high seas as the Observatory moves to the wreck of the Balboa, a 375-foot (114 m) freighter that sunk in a hurricane in 1932. The Observatory then returns to the dock in the heart of George Town, where you disembark.


  • Guided submarine ride on the Observatory

Know Before You Book

  • Children 1 and younger are complimentary.

  • You must be able to independently navigate a nearly vertical 10-step ladder into and out of the submarine.
