The Cenotes Yucatan Mexico
Yucatan and, particularly, Playa Del Carmen, in addition to the beautiful Caribbean dive sites offers to divers the possibility to experience a different type of dive : Scuba-diving in Cenotes.
Scuba diving in Cenote is more or less like a cave dive but has many advantages. This article aims to explain what is a cenote but also to advise divers and to present the best cenotes of the Yucatan.
What is a cenote?
The Cenote etymology comes from the Mayan word “zonot” or “tzonot” which changed into “Cenote” in Spanish. The Cenote is pronounced “Cé-no-té.” The Cenotes are actually caves or tunnels, which have been created thanks to the collapse of the limestone rocks. The craters, visible from the surface are filled with crystal clear water.
Mexico has the highest concentration and the greatest number of Cenotes in the world and specifically in the Yucatan. The Cenotes are present almost everywhere, some can be found in the deepest jungle while some others are in cities that have blossomed around these freshwater wells. They are also found in all sizes and shapes.
Some Cenotes are caves and tunnels, true underwater passages with large pools while some others are vertical, in the forms of large wells filled with water. The Maya considered the Cenotes as sacred doors opened on another world. Some Cenotes were also used for human sacrifice, 4 have been discovered, or Animal sacrifice. It is still possible nowaday to observe animal bones in the Cenote Cenote Pet Cemetry.The Cenotes, cultural and historical heritage of Mexico, are protected by the Convention on the Protection of Underwater Cultural Heritage
Diving in a Cenote
Scuba diving in Cenote is an exciting experience. The water is absolutely transparent, crystal clear and pure. The ceilings of the tunnels are bitten of hundreds of stalactites themselves dressed in green roots.
The tangle of tunnels sometimes lead to high rooms traversed by long rays of sun penetrating the darkness of the cave through small openings in the ceiling.

Origins and phenomena of the Cenotes
The geological phenomenon of the Cenotes
These unique formations are due to a sequence of geological events and to specific climatic disturbances. There are several million years, the Yucatan was submerged by tens of meters of water. It was only during the last glaciation, which resulted in a drop in sea level of nearly one hundred meters that the Yucatan Peninsula appeared out of the water.
Coral reefs created a large layer of limestone of almost two kilometers. Under the weight of the nascent jungle, porous and dry limestone eventually collapsed. At the end of the Ice Age, there are nearly 18,000 years, caribbean waters were lifts, immersing the network of tunnels and caves that communicate with the sea and various aquifers.
What are speleothems?
Speleothems are mineral deposits, usually consisting of calcium carbonate or calcium sulfate. The main types of speleothems are:
You can find all of these mineral formations in cenotes.
What are haloclines?
In Cenotes, you will discover the very characteristic and fascinating phenomenon of Haloclines. The haloclines are created by the clear sep of two layers of saltwater and freshwater. The phenomenon is particularly clear in Tajma Ha Cenote Cenote Tajma Ha.
The phenomenon is very visual and the demarcation between fresh water and salt water is very clear. In the presence of haloclines, when the diver is in the fresh and clear water, has the strange impression of being in flying over the water. In reality, the diver is in a cenote and fully immersed. The feeling appears to be very strange.
