There are more than 40 blue holes and underwater cave systems documented on Great Abaco Island thus far.  Only a handful of the caves on Abaco have been fully explored, leaving plenty of opportunities for divers with varying experience levels.

The inland caves on Abaco are generally located within the dense pine forests of the interior of the island. Some of the more remote sites are accessed by the old logging roads that criss-cross the island.  The lengths and depths of the caves on this island vary greatly.  With sinkholes that drop to depths in access of 340 feet, to the shallower, 80 foot deep, highly decorated passages of our lens caves, Abaco offers caverns, caves and sinkholes that will accommodate all levels of certifications and experience levels.  The Bahamas Underground's customized van is set up for the most convenient cave diving experience.

The creeks and protected lagoons of Cherokee Sound, Bight of Old Robinson, John Doctor Cay, Spencer's Bight and Crossing Rocks are literally riddled with shallow, decorated ocean caves.  Diving in an ocean cave is a bit more challenging than inland diving and requires timing the tides.  Ocean caves are affected by the tides, creating strong currents.  Local knowledge of tides and each cave's slack period,  allows divers to safely access these amazing systems that are found no where else in the world.  The psychedelic colors of the marine life that inhabit every surface of the walls, ceiling and formations of the caves are only found in the Bahamas.
