The zipa used to cover his body in gold dust, and from his raft, he offered treasures to the Guatavita goddess in the middle of the sacred lake. This Muisca tradition became the origin of the legend of El Dorado. Muisca raft in the Gold Museum, Bogotá, Colombia
The lake is circular and has a surface area of 19.8 hectares. The earlier theories of the crater's origin being a meteorite impact, volcanic cinder, or limestone sinkhole are now discredited. The most likely explanation is that it resulted from the dissolution of underground salt deposits from an anticline, resulting in a kind of sinkhole.
There are hot springs nearby in the municipality of Sesquilé, which means "hot water" in the now-extinct language of Chibcha, once spoken by the local indigenous people, the Muisca.
While the existence of a sacred lake in the Eastern Ranges of the Andes, associated with indigenous rituals involving gold, was known to the Spanish possibly as early as 1531, its location was only discovered in June 1537 by conquistador Gonzalo Jiménez de Quesada while on an expedition to the highlands of the Eastern Ranges of the Andes in search of gold. This brought the Spanish into first contact with the Muisca inhabiting the Altiplano Cundiboyacense, including around Lake Guatavita.
The lake is now a focus of ecotourism, and its association with the legend of El Dorado is also a major attraction.
The name of the lake is derived from Chibcha, the language of the Muisca: gwa: mountain or gwata, gwate: high elevation, or gwatibita: high mountain peak; hence, a pool at a high mountain peak. Another meaning is "End of the farmfields".
