Lake General Carrera
Lake General Carrera, known as Lake Buenos Aires in Argentina, is a glacially fed lake on the border of Chile and Argentina, renowned for its striking turquoise waters and famous Marble Caves.
Known by two different names depending on which side of the border you're standing, this glacially fed Patagonian lake has become internationally famous for a set of naturally sculpted marble caves rising from its brilliant turquoise waters.
A Lake with Two Names
The lake is known as General Carrera on the Chilean side and Buenos Aires on the Argentine side, reflecting its position straddling the international border between the two countries.
Striking Turquoise Waters
The lake is renowned for its brilliant turquoise coloring, caused by finely ground glacial rock flour suspended in the water, creating one of Patagonia's most photographed natural landscapes.
The Marble Caves
The lake's Marble Caves, naturally sculpted by thousands of years of wave action against calcium carbonate rock formations, have become a major tourist attraction accessible only by boat.
Glacially Fed Origins
The lake is fed significantly by glacial meltwater from the surrounding Andes Mountains, contributing both to its distinctive coloring and its position among the deepest lakes in the Americas.
