The Cascadas de Agua Azul (“Blue-water Falls”) are found in the Mexican state of Chiapas. They are located in the Municipality of Tumbalá, 69 kilometers from Palenque by the road that leads towards San Cristóbal de las Casas.
This waterfall consists of many cataracts following one after another as can be seen in the first photo in the picture gallery, taken from near the top of the sequence of cascades. The larger cataracts may be as high as 6 meters (20 feet) or so.
The water is as blue and has a high mineral content. Where it falls on rocks or fallen trees it encases them in a thick shell-like coating of limestone.
During much of the distance the water descends in two streams, with small islands in the middle.
