Dean’s Blue Hole: Visiting the World’s Deepest Blue Hole in Long Island
Dean’s Blue Hole is one of the most extraordinary natural attractions in The Bahamas and one of the deepest blue holes on Earth. Located on the rugged southern coast of Long Island, this dramatic inland blue hole drops more than 660 feet straight down into the limestone bedrock, creating a site that is both visually stunning and scientifically significant.
For travelers, Dean’s Blue Hole is not just a place to see; it’s a place to feel. The contrast between its calm, shallow turquoise rim and the sudden plunge into deep indigo water makes it unforgettable, whether you are swimming, snorkeling, or simply standing on the cliffs taking it all in.

Crystal-clear water with exceptional visibility
