Diving the collapsed pits and sinkholes of the Yucatán Peninsula is a world away from the rich coral reefs and walls off Playa del Carmen and Cozumel. Besides the odd fish or terrapin, the cenotes are pretty much devoid of animals. But alongside the crystal clear water, the rock formations (which vary from clumps of fragile stalactites to grandiose boulders and chambers) and the interaction with the world above (be that from tree roots working their way down the rock or shafts of light burning through the darkness) come together to produce a stunning experience for the diver.
The line (a literal life-line) must be followed. Also, spot the terrapin centre left.
Some caverns contain air pockets where it’s possible to surface. Where a route to the ground above exists, these caverns often become home to bats.
Rudimentary structures often form the access to otherwise pretty inaccessible pits.
Enormous formations of stalagmites & stalactites grace certain chambers.
Secondary air sources are a must - redundancy is everything in the caves & caverns.
Shafts of light aggressively pierce the dark water and tree roots dangle many metres down through the limestone.
