A cenote is a deep natural pit, or sinkhole, characteristic of Mexico, resulting from the collapse of limestone bedrock that exposes groundwater underneath.
These underground rivers are amazing to swim in, their cold turquoise water and the magical formations of limestone stalactites and mites make it a unique experience.
On the map you can see a few of the local cenotes marked south of Playa Del Carmen, they are all beautiful and different from each other. The entrance fee is somewhere between 50 and 150 pesos.
In Puerto Morelos you will find the Cenote Trail . Near Cobá ruins you will find el Multun Ha, Tankach Ha and Choo Ha the price for all cenotes is between 100 and 150 pesos. ( you will need a car)
Yucatan has many amazing cenotes, the most famous the cenote sagrado at Chichen Itza, and equally impressive cenote with a plus that it is suitable for swimming is Ik-kil.
Ik-kil and Dzitnup are near Chichen Itza and can be visited along with Valladolid on a day trip from Playa Del Carmen
