Thunderball Grotto is a submerged limestone cave system located between Staniel Cay and Big Major Cay in the central Exuma Cays of The Bahamas. Widely recognized as one of the most famous snorkeling locations in the country, the grotto is known for its underwater passages, natural skylights, clear water, and abundant tropical marine life. The site gained international recognition after appearing in the James Bond film Thunderball and later in other film productions. It remains one of the most visited natural attractions in Exuma.
Located just offshore from Staniel Cay, Thunderball Grotto sits within a protected marine environment surrounded by shallow turquoise waters and coral habitats. Visitors typically access the cave by boat from Staniel Cay, Great Exuma, Compass Cay, or nearby marinas throughout the Exuma Cays. Depending on tide conditions, swimmers and snorkelers can enter through openings in the limestone rock formation and explore the cavern's interior chambers.
The grotto is particularly known for its visibility, schools of tropical fish, underwater cave openings, and sunlight streaming through natural roof vents. These features create one of the most photographed and recognizable marine environments in The Bahamas. Many Exuma boat tours include Thunderball Grotto alongside Big Major Cay, Compass Cay, Bitter Guana Cay, and other nearby attractions.
