The dive begins a short distance from the parking lot of the Little Brother cenote. Passing through a short tunnel, you reach Chac Mool among splendid plays of light and halocline. With its large rooms and its maximum depth of 12 meters this site is perfect for a first experience of diving in a cenote. There is also an air dome created by the collapse of the ceiling where you can emerge to admire the small stalactites that grow from the ceiling. This cave offers the possibility for more experienced divers to admire the largest underwater stalactite in the world "El Monstro".
