07. Dean’s Blue Hole (Bahamas)
Dean’s Blue Hole is one of the deepest blue holes in the world. The most spectacular thing about this hole is that the beach surrounds it. It is to some, a crown of Bahamas. If you have the nerve and call yourself an adventurer, climb up the rocky pathway and plunge into the 663 feet depths of this beauty. It is a famous spot for snorkelers in the Caribbean so you should have a go at it.
