Diving in cenotes is a once-in-a-lifetime experience. You will get to explore natural sinkholes formed from limestone bedrock. The word cenote comes from the Mayan word dzonot or ts’onot, literally meaning “cave with water”. The cenote begins as an underground chamber created when limestone is dissolved by the action of rainwater. Finally, as the cavity grows in size, the cenote ends up reaching the surface when the roof finally falls away. Don’t miss your chance to feel the adrenaline with our scuba diving in cenotes.
Cenote Diving in Tulum
In the Yucatan Peninsula there are complex, intertwined passages between underground cenotes, forming networks that occasionally make their way to the sea. In these cases, seawater – more dense than freshwater – can enter through the bottom of the system.
There are cenotes where at a certain depth the water changes from fresh to salty, the meeting point between the two being called the halocline. A halocline can cause fascinating visual effects, which have to be seen to be believed.
There are several types of cenotes: open, semi-open and “underground sky” or grotto. This classification is related to the age of the cenote, with mature cenotes being those which are completely open to the sky, and the youngest those which still retain an intact overhead dome.
Dive in Deep Cenotes
It’s in the deepest cenotes where the halocline effects are the most obvious, and glorious! When you pass through the cloudy halocline layer you’ll notice the change in temperature and buoyancy caused by the different densities of water. Diving in the sea and in deep cenotes are adventures everyone should experience.
