I didn't dare bathe in the cenote, though I had intended to. But it's not the same view when you see one in a photograph as it is to walk down a cave mouth, on a stone staircase and be hit suddenly by the dark humidity. Even though the water was very clean and illuminated, it only impressed by a little. So I just watched the natural stone dome and took some pictures, which you can see gives an almost scary feeling with the dark, quiet waters. There are many cenotes in the Yucatan, which used to be used as water tanks and supposedly as altars to the gods of water. Many valuables have been found in them that were thrown in by a priest making a tribute.
