The infamous Blue hole near Eleuthera and Harbour Island in the Bahamas is shrouded by mystery. The ancient natural formation is actually a large marine cave, which is open at the surface. Blue holes typically have tidal fresh and marine water combined.

Ocean hole near Harbour Island in the Bahamas was created during the last ice age; roughly 10,000 years ago. Sea levels at the time were almost 400 feet lower than they are today. The hole itself can have side caves, which can extend as far as 2,000 feet. These “caves” are created from the desalination of where fresh and saltwater meets; eating away at the rock.

The blue hole near Eleuthera in the Bahamas was discovered by Marine explorer Jacques Cousteau. The hole is the second deepest submerged cave system in the world at a depth of over 663 feet. You can dive it, although the deeper you go, the less oxygen there is in the water. The water also becomes potently poisonous after about 180 feet; so bring extra thick wetsuits and tanks; and remember to constantly guard your depth reader and oxygen levels.

The blue hole is famous for another deep sea danger, Giant Octopus. Known in local legend as the Lusca, an infamous deep sea creature has been blamed for centuries in taking the lives of sailors and divers. The animal is believed to actually be a giant octopus, with some known to even harass divers while visiting the blue hole in Eleuthera Bahamas.

Take caution and dive with a buddy, because you never know what you may see down there. The holes are known for being almost lifeless after a certain depth, but not prior to 180 feet.

Besides local lore and legend, the blue hole near Eleuthera and Harbour Island in the Bahamas offers a sense of mystique and awe that only mother nature can display. To get to the blue hole, visit the docks in downtown or in Spanish Wells and see if a captain or local group tours can accommodate you. A visit to the Blue Hole is well worth instigating; and a quick snorkel or dive will make the experience even more magical.
