A cenote is a natural sinkhole formed by the collapse of limestone bedrock that exposes an underground river. While the best-known cenotes are large open-water pools measuring 30-150 feet in diameter where the entire ceiling of the cave callasped, such as those at Chichen Itza in Mexico, the greatest number of cenotes are smaller sheltered sites and do not necessarily have any surface exposed water. Some cenotes are only found through small diameter holes created by tree roots, with human access through enlarged holes, such as the cenotes Choo-Ha, Tamcach-Ha, and Multum-Ha. There are at least 6,000 cenotes in the Yucatán Peninsula of Mexico.
Cenote water is often very clear, as the water comes from rain water filtering slowly through the ground, and therefore contains very little suspended particulate matter. The groundwater flow rate within a cenote may be very slow. In many cases, cenotes are areas where sections of cave roof have collapsed revealing an underlying cave system, and the water flow rates may be faster.
We traveled through the Mexican Yucatan trying out as many of the over 6000 found in this region. The video below is a countdown of our favorites. If you want to see more about each one then make sure you hit the SUBSCRIBE button and the bell icon, because I will be making a second travel video about our 30+ days in Mexico and this one is going to be called Mayans & Cenotes. So you want to make sure you are notified when it comes out so you can check it out!!!!
