Southern Ice Field Expedition, “Marconi-Viento”


The Patagonian Ice Cap is the third largest extension of ice of the world, and the biggest in South America. It has an average height of 1500m/a/s/l, and it can be described like a vast plain covered with snow and crossed by the Andes from north to south.
In this program, we will circumnavigate the Fitz Roy & Cerro Torre mountain range, covering a distance of aprox. 90km. This is one of the most challenging and impressive trips of Southern Patagonia.

Day 6

Trek over “Paso del Viento”(1500m/a/s/l) and then down the Tunnel valley to get to Laguna Toro. In a clear day, there are excellent panoramic views of Mariano Moreno Range and Viedma Glacier.
