Blue holes are found throughout the Bahamas, with Andros spearheading the list. Many blue holes are also plentiful in the Exumas. The blue holes of the Bahamas are unique geological features as they are the only tidal blue holes in the world. Most holes are circular and reach great depths from 250 to 650 feet.
A vast flooded labyrinth of caverns, caves and submerged tunnels, part of an elaborate cavern system, can be found by further exploring into the blue holes. While this type of exploration is suitable only for highly trained divers, exploring the top levels of a blue hole can be done by any certified diver.
While the inland caves are not populated with underwater life, it is possible to find creatures such as gray snappers, blind cave fishes and remipedia.
Precautions involve diving the hole at the appropriate time. As inland blue holes are connected to the ocean, they will suck water in on a rising tide, thus creating a downward vortex. Visibility is compromised and it can be dangerous. Diving a hole on a falling tide present much safer conditions. Clear ocean water flows into the hole, thus allowing better visibility. Nevertheless, always consult knowledgeable local operators.
