Lago Argentino is the largest freshwater lake in Argentina, sprawling across 1,415 km² (546 mi²) in the Patagonian province of Santa Cruz, with a maximum width of 32 km. Fed primarily by glacial inflows — including the iconic Perito Moreno Glacier to the south-southwest and the retreating Upsala Glacier to the north-northwest — as well as the La Leona River, this is a glacier lake of extraordinary scale and depth. The lake sits at an elevation where its deepest point reaches 541 m below mean sea level, with an average depth of 155 m (509 ft) and a maximum depth of 719 m (2,359 ft), the deepest point located at the end of the narrow north-northwestern arm near the Upsala Glacier. The glaciers carve deep trenches into the bedrock as they calve into the lake, creating dramatic underwater topography. The nearby town of El Calafate serves as the primary hub for visitors, offering a full range of accommodations and services. The lake is a well-regarded fishing destination in Patagonia, appreciated for its wild trout fishing in a spectacular glacial landscape.
