A few miles to the east of Valladolid toward the town of Yalcobá you will find the more unknown Agua Dulce or Ch’ujuk Ja. There is a narrow spiral staircase descending into the cenote, and once there you will see a beautiful pool with shafts of natual light coming down, as well as artificial lighting showing the cave.

Exactly what is a cenote?
A cenote is formed, usually from limestone, when caves or channels are carved through the rock, forming underground rivers. As rain water seeps into the layers of sandstone, it slowely erodes channels toward the ocean. Eventually they grow bigger and bigger, and in some spots giant caves are formed, along with stalagmites.
In the Mexico, cenotes are only found in the Yukatan, and it is believed that is because a meteorite hit there millions of years ago, and created a thick layer of sandstone there. Since then water has been creating the underground rivers, caves, caverns and cenotes we see today.
After the ice age, these caves and channels that were mostly dry, filled with water, which is why we have vast cave systems through the Yukatan, and in spots deep underwater you can still find skeletons of long dead land animals. Such as the extinct North American camel and giant ground sloth.
Cenotes range from between 66 million years and 13 thousand years old. The actual cenote is formed when the roof of a cave or wide underground river caves in, exposing it to the sun, and letting us in. As you can see from the photo above, the whole system isn’t called a cenote, just the opening area from the collapsed ceiling.
So all “cenotes” you visit might be cenotes, but when you dive deep into them, you are diving into caverns and cave systems, not only the cenote itself. And for most, this is a memory of a lifetime.
