A "Cenote" or "Cenotes" (plural)is the name given in the south part of Mexico and centro-america for a large, subacuatic cave, (or series of) usually a "Cenote" has a mayan-linkage, because these was a important part of their rites. A Cenote, viewed from outside, may look like a small lake, with cavernous entrances near, and/or a thick jungle. In fact, All of the cenotes are always surrounded by the rich mayan jungle. The pre-hispanic Mayas have rites of trowing large pieces of gold as a manner of sacrifice, and for that, most of the cenotes were explored in the first part of the 20th century. Now, they remains as a good attraction to divers, but they can be very dangerous, since most of then have underwater currents.
