Lago Nordenskjöld is a stunning glacial lake nestled within Torres del Paine National Park in the Magallanes Region of southern Chile, situated at approximately 51°02′S, 73°00′W. Stretching roughly 15 kilometers in length with a surface area of about 28 square kilometers, the lake sits dramatically at the foot of Los Cuernos and is fed primarily by the Paine River. Its outflow cascades westward through the iconic Salto Grande waterfall. The lake is renowned for its striking emerald-green waters — a characteristic product of glacial flour suspended in the water column — set against one of the most spectacular mountain backdrops on earth. The surrounding landscape supports abundant wildlife, including large herds of guanaco along the southern shoreline near Salto Grande.
