cenote (from the Maya dz’onot, meaning “abyss” or “hole with water”) is a natural sinkhole formed by the collapse of limestone bedrock, exposing a hidden pool of groundwater underneath. These breathtaking formations are found almost exclusively in the Yucatán Peninsula of Mexico, which is estimated to have over 10,000 of them. [1, 2, 3]

Cenotes

Their appearance depends on their geological age and how much of their ceiling has collapsed: [1, 2]

• Cavern Cenotes: The youngest type, mostly enclosed with only small openings for light.
• Semi-open Cenotes: Middle-aged formations where part of the ceiling has fallen away.
• Open Cenotes: Older formations where the roof has completely collapsed, resembling a natural pond or lagoon.
• Ancient Cenotes: Completely open and similar to small lakes. [1, 2]

Cultural & Historical Significance

To the ancient Maya, cenotes were far more than just swimming holes:

• Life Source: In a region with no surface rivers, they provided essential fresh water.
• Spiritual Portals: They were considered the entrance to Xibalbá (the underworld) and sacred sites for rituals and offerings to the gods.
• Guardians: Mayan legends speak of Aluxes, small mythical beings that protect these waters. [1, 2, 3, 4]
