Cavern and Cave Training
Xanadu Undersea Adventures offer cavern and cave training through the
National Association for Cave Diving (NACD)
, the oldest of the dedicated cave diving training organizations. This type of training is special, in that listed dive requirements are minimums, and certification is only issued upon attainment of the skills and mindset to safely participate in this type of diving independently. Additional time incurs additional cost. The four levels of training are as follows:
Cave Diving & Cavern Diving
BLUE HOLE (cavern/Cave) DIVING
The caves and Caverns are a hidden part of Grand Bahama, a secret realm that only a few visitors will ever know about or take the time to understand. What you cannot see beneath the surface is an immense underwater cavern, the gateway to a vast, flooded, labyrinth of caverns, caves and submerged tunnels that honeycomb the entire island of Grand Bahama and the surrounding sea bed.
Cavern tours are available to any open water certified diver, and offer a chance to explore underwater forests of stalagmites and stalactites, pass through the weird transition zone between fresh and salt water(or halocline), and see ancient fossilized coral reefs, all in the absolute quiet and calm of the area of the cave where ambient light from the entrance is always visible. Our cavern guides are all cave certified and equipped, as well as open water divemasters or higher, and we restrict our groups to a maximum of 4 divers per guide. Grand Bahama Island offers 3 cavern zones large enough for an excellent cavern diving experience, they are:
Located in the Lucayan National Park, Ben's is the easiest of our cavern dives, yet offers all of the aspects which makes cavern diving special, including speleothems, halocline, fossilized coral reef and calcite crystals, all housed within a large and beautiful ambient light zone. Park rules which allow only one group of divers every second day guarantee perfect conditions, but necessitate early reservations. An additional $10 entrance fee is charged by the National Trust.
For the diver who relishes leaving the beaten path, Mermaid's is the place for you. The entrance pool looks like a puddle hidden among the Bahamian forest, upon entering; you'll find yourself in a huge room offering some of the best cave formations to be seen within any cavern zone.
The forty foot descent to the water by ladder leaves this cavern for the dedicated cavern explorer only. The reward awaits underwater, with the largest of the island's ambient light zones, pristine halocline, and stunning views back towards the entrance.
Cavern Tour Prices;
The cavern dives have an $80 surcharge over your dive package price, not including equipment rental(or dive lights), but including tanks, weights, and transportation. Minimum 2 divers per group.
Cave Diving Tours
For certified cave divers only! Grand Bahama Island offers nearly 10 miles of explored underwater cave. Our experienced cave diving guides can show you the best of it, for those who only need tank fills and directions, we'll be glad to help.
Cave Tour Prices;
Cave dives have an $80 surcharge above your dive package price, including transportation and guide, but not including tanks, lights, or other cave equipment.(see below for rental price list).
This five dive course typically takes 2-3 days and 5 dives (four within the cavern zone). A course which would benefit all open water divers looking for outstanding buoyancy skills, proficiency with reels, and a reinforcement of dive planning techniques. The course opens up a whole new diving environment, and its skills are directly applicable to wreck diving.
$400, plus a $30 certification fee upon successful completion.

Your first step beyond the cavern zone, allowing limited exploration of the cave zone, and covering the techniques for safely achieving this.
$400, plus $30 certification fee, 4 dives after cavern.
Cavern plus intro, 9 dives, $800 plus $30 certification fee.
Allows for deeper exploration of the cave zone, and is the ideal stepping stone to the full cave certification.

For the most part, the inland caves are not exactly teaming with life but there are creatures living in the caves other than the migrating Gray Snappers. The full time residents include a type of blind cave fish and a relatively new species of animal found lurking in dark passages. Fortunately, the creature, Speleonectes Lucayensis, is not a threat to cave divers. It's only an inch or so in length and looks a bit like a swimming centipede.
The caves in the Bahamas were formed during the last ice age. With much of the earth's water held in the form of glacial ice, the sea level fell hundreds of feet, leaving most of the Bahama banks, which are now covered in water, high and dry. Rain falling on the most porous limestone, slowly filtered down to sea level forming a lens where it contacted the denser salt water of the ocean permeating the spongy lime stone. The water at the interface, was acidic enough to dissolve away the limestone and form the caves. Then, as more ice formed and the sea level dropped even further, the caves became dry and rainwater dripping through the ceiling, over thousands of years, created the incredible crystal forests of stalagmites which now decorate the caves. Finally, when the ice melted and the sea level rose, the caves were reclaimed by the sea.
The surface water you see in these caves is fresh and pure. It's rainwater that seeps through the porous limestone just as it did when the caves were created, forming a giant lens that floats on the under layer of sea water. When you dive in the caves, at a depth of about 25 to 30 feet, you can see the fresh / alt water interface, or "halocline," as a distinct line separating the liquids, and if you watch a diver passing through the halocline, their image is momentarily blurred and distorted by the mixing of the fresh and salt water.
