Dean’s Blue Hole is the second deepest Blue Hole in the world and a natural wonder, with a depth of 663 feet (202 mt), and a surface of 80 x 120 feet (25 x 35 mt). It’s roughly circular on the surface, with a diameter of 82-115 feet (23-35 mt.), which increases up to 330 feet (100 meters) and becomes a cavern as you go down.

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 makes Dean’s Blue Hole one of a kind.

What makes Dean’s Blue Hole so special is not only its depth, but the fact that winds 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.

Location


Formation
