What is a blue Hole?

A blue hole is a water -filled sinkhole with the entrance below water level. The majority of them will have a maximum depth of 300 feet, which is what makes Dean’s Blue Hole so special.

Dean’s Blue Hole is named after Captain William Henry Dean, who was a Bahamian fisherman and local legend. The hole is a captivating sight with its deep blue waters surrounded by stunning limestone cliffs. The crystal-clear visibility of the water allows divers to witness the incredible underwater ecosystem that thrives within its depths. Wind does not reach the area, creating a lagoon of crystal clear waters with no waves, enclosed by a  natural rock amphitheater on one side and by cliffs and white sand beaches on the other.

It is an excellent place for diving and snorkeling, considered to be one of the best ones in the world, thanks to its depth, clear waters, beauty and the incredible marine fauna that surrounds the area: sea turtles, colorful fishes, snappers, seahorses, tarpon and even rays. It is also the place where the free-dive championship is held every year.



No one really knows how Dean’s Blue Hole was formed, it’s presumed that it was due to underwater erosion, caused by the chemical reaction of fresh and saltwater mix and the dissolution of the limestone.
