The Cascadas de Agua Azul are a series of waterfalls found on the Xanil River in the southern Mexican state of Chiapas. They are located in the Municipality of Tumbalá, 69 kilometres from Palenque.
These waterfalls consists of many cataracts following one after another, taken from near the top of the sequence of cascades. The larger cataracts may be as high as 6 meters (20 feet) or so. During much of the distance the water descends in two streams, with small islands in the middle.
The water has a high content of calcium carbonate and other minerals, and where it falls on rocks or fallen trees, it encases them in a thick shell-like coating of limestone.
