Cousteau's Blue Hole is one of the most scientifically significant inland blue holes on Andros Island, earning its name after the renowned French oceanographer Jacques Cousteau, who explored the island's blue holes during an expedition in 1970–1971. Cousteau's investigations helped bring international attention to the remarkable underwater cave systems of Andros and demonstrated that inland blue holes were connected to the surrounding ocean through extensive submerged limestone passages.
Located on South Andros, Cousteau's Blue Hole is part of the island's extraordinary network of more than 170 inland blue holes and numerous offshore blue holes, the highest concentration found anywhere in the world. Unlike Captain Bill's Blue Hole, which is developed for recreational visitors, Cousteau's Blue Hole remains a remote natural site primarily known for scientific research and technical cave diving. Its depth is still not fully determined, adding to its reputation as one of Andros' most mysterious geological features.
The blue hole played a pivotal role in understanding Andros' subterranean hydrology. During his expedition, Jacques Cousteau released fluorescent dye into an inland blue hole, which later emerged offshore in the Tongue of the Ocean, proving that the island's inland and ocean blue holes are interconnected through an immense underwater cave system. This groundbreaking experiment transformed scientific understanding of Bahamian karst geology and freshwater systems.
Today, Cousteau's Blue Hole remains an important destination for scientific expeditions, experienced cave divers, and visitors interested in the natural history of Andros. Although it is not a developed swimming attraction, its historical association with Jacques Cousteau and its role in revealing the hidden cave systems beneath Andros make it one of the island's most fascinating natural landmarks.
