Did you know?

Here are 4 amazing facts about the underground river:

1) In all the Yucatan peninsula, there is neither lake nor watercourse. The underground river was, therefore, the only source of freshwater in the region. The water is drinkable but very limestone, which explains the physiognomy of the Mayans (small, stocky with strong bones and with a small neck).

2) This region of Mexico is like a cheese gruyère, all the river system of the peninsula is underground and all cenotes are interconnected.

3) At the time of the Hispanic invasion, the Mayans were hiding inside the underground river (about 25 meters underground).

4) Few animals survive in this harsh environment: three types of fish (one type of shrimp, catfish, blind fish – with no eye cavity).
