Lago Rivadavia is a stunning glacial lake nestled in the Andes of Chubut Province, Argentina, sitting at an elevation of 527 metres (1,729 ft) in a fjord-like trench between glaciated peaks. To the east rises Sierra Rivadavia at 1,924 metres (6,312 ft), and to the west stands Cerro Coronado at 2,097 metres (6,880 ft), with glaciers descending the mountain slopes to approximately 1,500 metres (4,900 ft). The lake occupies a narrow north-to-south valley of glacial origin and is part of the Futaleufú River system, which ultimately flows into the Pacific Ocean via Yelcho Lake and the Yelcho River in Chile. It is the second lake in this chain, after Lago Cholila to the north. Nearly all of the lake lies within Los Alerces National Park, with only the northern tip extending beyond park boundaries. The waters are famously clear, and the surrounding landscape — with its beech forests, snow-capped peaks, and lush riparian vegetation — makes this one of the most visually spectacular fishing destinations in all of Patagonia. The Jara River joins the lake on its western side near the southern end, and the lake's outflow is the Río Rivadavia, which flows 6.7 kilometres (4.2 miles) southward into Lago Verde.
