On the northwest end of Exuma Cays and southwest of Staniel Cay, the snorkeling at Thunderball Groto is known for coral heads in sand flats. You may encounter angelfish, parrotfish, grouper, octopus, sergeant majors, queen angelfish, jacks and stingrays.

The Thunderball Groto is located southwest off Staniel Cay or 1.5 miles to the southeast of Fowl Cay. Also known as Thunderball Cave, the best way to access the Thunderball Groto snorkeling is via a private boat or a live-aboard charter. The waters at this boat-accessed snorkeling dive site ranges from 5 feet to 25 feet. The groto itself can only be accessed at low-tide. When you dive down and pass through the groto entrance, you will find that the cavern opens up and light from the outside comes in through natural holes in the cavern ceiling 20 feet above.

To reach the snorkeling at Exuma Cays, most travelers will fly commercial airlines into Nassau on New Providence or fly into Freeport on Grand Bahama Island.

Note, it is sometimes possible to fly commercial air from southern Florida into Great Exuma Cay, such as the United/Silver Airways flights from Ft Lauderdale to Georgetown.
