Blue Holes, Caverns, Caves
The Islands Of The Bahamas’ walls offer breathtaking vistas, populated by colorful marine life. Whether inland or submerged in the sea, the incredible blue holes are the result of centuries of freshwater dissolving and redepositing limestone. As a result, walls and blue holes are simultaneously special and widespread dive experiences in The Bahamas.
Walls, the most generally dramatic expression of the coral reef, will at times plummet directly into the great trenches thousands of feet deep that line the archipelago. Blue holes, while not exclusively a phenomenon of The Bahamas, are found here in a greater number than anywhere on earth. And, The Bahamas has the only known tidal blue holes in the world. Together, the walls and blue holes turn The Bahamas dive experience on its side.
Blue holes are a phenomenon created during several ice ages, when sea levels were 400 feet lower and The Bahamas was a great exposed limestone platform. Centuries of acidic rain water etched into the vast bank, creating circular depressions and other magnificent formations. Today, most blue holes are located in shallow water on the Great and Little Bahama Banks, while others are inland pools.
