Fodor's Expert Review Thunderball Grotto

Just across the water from the Staniel Cay Yacht Club is one of The Bahamas' most unforgettable attractions: Thunderball Grotto, a lovely marine cave that snorkelers (at low tide) and experienced scuba divers can explore. In the central cavern, shimmering shafts of sunlight pour through holes in the soaring ceiling and illuminate the glass-clear water. You'll see right away why this cave was chosen as an exotic setting for such movies as 007's Thunderball and Never Say Never Again, and the mermaid tale Splash.
