Thunderball is famous for its underwater brawls including one where Bond fights with villain Largo’s henchmen in a series of submerged caves. This scene was a filmed at a cave near Staniel Cay, in the Exuma island chain of The Bahamas; the cavern was renamed Thunderball Grotto after the film. Although the film location initially looks unimpressive from the outside, the area is similar to a Swiss cheese as it is a hollow island with holes going through it. Once you swim through you are greeted by numerous large chambers with fantastic fish.
How to visit on a superyacht: The nearby Staniel Cay Yacht Club can accommodate yachts of up to 56 metres and has a popular restaurant and bar. Afterwards you can visit Big Major's Spot where you can swim with the island’s famous pigs — definitely something to ticked off your Caribbean bucket list.
