Treasure Lake is located in the Guamá tourist centre on the Zapata Peninsula. It is 16 square km in area and is 4km wide at its widest point. At its centre it is six meters deep on average. In connection with its name, it has been claimed that the Ciboney Indians and the chiefs of Yaguarama and Hanábana indians came to this place to give water as offerings to the gods, and the gold that the conquistadors had so eagerly sought. It is assumed this is the reason it began to be identified as Laguna del Tesoro (Lake of Treasure).
