BLUE HOLE

Popularized by a Jacques Cousteau television special, this has become the most famous dive site in all Belize. If you are interested in diving this site, we can provide day and/or overnight dive trips from Ambergris Caye, Belize City or various other offshore Cayes and Atolls.

Like a giant pupil in a sea of turquoise, The Blue Hole is a perfectly circular limestone sinkhole more than 300 feet across and 412 feet deep. The array of bizarre stalactites and limestone formations which mould its walls seem to become more intricate and intense the deeper one dives. Near to The Blue Hole, one of Belize's largest protected areas, Half Moon Caye Natural Monument, encompasses 10,000 acres of the atoll and 15 square miles of surrounding waters.

The diameter of the circular reef area stretches for about 1,000 feet and provides an ideal habitat for corals to attach and flourish. The coral actually breaks the surface in many sections at low tide. Except for two narrow channels, the reef surrounds the hole. The hole itself is the opening to a system of caves and passageway that penetrate this undersea mountain. In various places, massive limestone stalactites hang down from what was once the ceiling of air-filled caves before the end of the last Ice Age. When the ice melted the sea level rose, flooding the caves.

The temperature in the Blue Hole at 130ft is about 76F with hardly any change throughout the year at that depth.

For all the practical purposes the over 400-foot depth makes the Blue Hole a bottomless pit. The walls are sheer from the surface until a depth of approximately 110 feet where you will begin to encounter stalactite formtions which actually angle back, allowing you to dive underneath monstrous overhangs. Hovering amongst the stalactites, you can't help but feel humbled by the knowledge that the massive formation before you once stood high and dry above the surface of the sea eons ago. The feeling is enhanced by the dizzying effect of nitrogen breathed at depths. The water is motionless and the visibility often approaches 200 feet as you break a very noticeable thermocline.

In the deeper waters of the Blue Hole itself, you might see a curious blacktip tiger or hammerhead shark, but on most dives you won't see anyone except your dive buddy. Little light reaches the depths of the Hole and water does not circulate freely. As a result, the deeper areas inside the Blue Hole don't have the profusion of life associated with most drop-offs. But as you venture into the shallows around the rim of the Blue Hole to off-gas after your dive, you will discover a wonderful area filled with life.
