The cenotes were formed by the collapse of limestone bedrock, revealing underground river systems.
Natural sunlight creates the iconic light-beam effect through narrow holes in the cave roof.
The water is consistently cool, providing a significant thermal shift from the humid exterior temperatures.
The limestone walls show visible evidence of mineral leaching and centuries of geological buildup.
The pools are home to small, harmless freshwater fish that often swim near visitors.
Cenotes Dzitnup, also known as Cenote Xkeken and Cenote Samula, comprises two distinct subterranean limestone sinkholes located near Valladolid. These caverns feature turquoise, crystal-clear groundwater illuminated by natural shafts of sunlight filtering through limestone apertures in the ceiling. The rock formations contain numerous stalactites and stalagmites created by mineral-rich water erosion over millennia. The sites are partially enclosed, providing a controlled environment for swimming and freshwater exploration. Indigenous freshwater fish species inhabit the pools, often interacting with visitors. The location has been developed with visitor facilities including changing rooms, showers, and on-site vendor areas.
