The Southern Patagonian Ice Field feeds 48 glaciers, of which the Perito Moreno Glacier is the largest. Whilst most of the glaciers in the world are retreating due to global warming, Perito Moreno is actually expanding, for reasons which are not fully understood.
The ice dam formed by the glacier rises 30m above Argentino Lake, a truly remarkable sight. One of the things which will surprise you is the colour of the ice. More often, glaciers are sugar white, fading in places to muddy brown, but as you gaze in awe, from the boat, the ice wall glows iridescent blue.
We encourage you to get out on the ice on a mini trek. You’ll disembark opposite the Bajo de las Sombras, then hike from the lake shore to the edge of the glacier. In two hours you’ll explore the glacier’s varied landscape, from its streams and crevasses to the gullies and small lagoons.
