Cenote Dzitnup

Near the town of Valladolid, Mexico, is one of many water-filled sinkholes that can be explored on the Yucatán Peninsula.
But Cenote Dzitnup is worth the stop. Found just southwest of the town of Valladolid on the way to the Maya ruins at Chichén Itzá, it is an archetype of the unique karst (porous limestone) geology ubiquitous on the Yucatán Peninsula, where water-filled sinkholes called cenotes were literal wellsprings of a civilization.
