An unmissable journey for all those who enjoy multi-day routes and breathtaking landscapes. 4 intense days where you will travel through pampas, streams, rivers and glaciers up to 1500 meters above sea level to appreciate the immensity of the Southern Patagonian Ice Field.

The trails are not signposted as in the case of the treks that are part of the backbone network (Laguna de los Tres, Laguna Torre, etc.), nor is there medical assistance nearby or campsites with amenities.
Use the described information only as a reference, and before starting it is recommended to go to the “Cerferino Fonzo” Visitor Center to obtain updated information about the route and the necessary equipment.
