Thunderball Grotto

Thunderball Grotto is a small, hollow limestone cay just off Staniel Cay in the Exumas, famous as a location in the Bond films Thunderball and Never Say Never Again. At low tide you can duck-dive or swim through a low opening into a domed inner cavern, where shafts of light drop through holes in the roof onto clear water thick with sergeant-majors and other reef fish. It is one of the set-pieces of almost every Exuma boat tour.
