The Yucatán Peninsula has countless natural wonders, the most unique of which is probably the cenote.

The cenotes are basically huge collapsed cave chambers, opening a window from the surface to the water filled caves.
For the Mayas living on the Peninsula these served as a source of drinking water and the round holes were considered as sacred places. The word cenote derives from the Mayan word ‘d'zonot’, which means natural well.

The fresh water in the caves is nothing else than rain water filtered through the porous limestone. This water slowly but constantly flows towards the sea, dissolving more and more of the limestone walls of the cave, making the passages grow bigger and bigger.

There are more than 3.000 cenotes on the Yucatán Peninsula, which are protected treasures of the region. The best known are Chac Mool, Gran Cenote and Dos Ojos in the Riviera Maya.
