The word "cenote" comes from the Mayan language "ts'ono'ot" or "d'zonot" which means "water hole".
Cenotes are natural wells, filled with fresh water and sometimes a lower layer of seawater. The Yucatán peninsula is estimated to have no less than 10,000...only a minority of which have been explored.
They communicate with each other through a complex system of underground rivers.
Their beauty, shape and depth vary from one cenote to another. The formation of stalactics and stalagmites found inside takes you back millions of years, adding to that the play of light that takes you to another dimmesion...the magic of cenotes works.
