Lake Buenos Aires is so named by the Argentines. On the Chilean side, it is called Lake General Carerra. As you can see, it is located on the border between Argentina and Chile.
With an area of 1,850 km2, this ancient glacial basin is the fourth largest lake in South America after Lake Titicaca. Coming in first is Lake Maraicabo in Venezuela then Lagoa Dos Patos in Brazil. Some specialists argue that the latter is more of a lagoon than a lake. Anyway, third or fourth, you are facing a giant. The wind reigns supreme here. You see this very quickly when you see the few trees battered by the elements in certain very exposed places.
This vast expanse of water is renowned for its Catedral de Mármol (“Marble Cathedral”), a rock located in its middle (in Chilean territory) and composed of rocks of white and marble tones.
