Dean's Blue Hole, Bahamas

There may be bigger and more impressive blue holes, but Dean's Blue Hole on Long Island in the Bahamas is the world's deepest at more than 600 feet deep. Blue holes, named for their vibrant color as seen from above, are subsurface voids that contain fresh, marine or mixed waters that extend below sea level. They are open to the surface and may provide access to submerged caves. More photos...
