Meeting with the Guide in the morning; debrief about the details of the program and check of the equipment. We´ll start the trek at noon from El Chaltén and hike towards “Laguna Toro” campsite, passing over the “Pliegue Tumbado”.
This hike takes about 5-6 hours and has an elevation gain of 500m. We will camp at Laguna Toro (650m/a/s/l).


After 30 or 40 minutes of hiking, we´ll get across the Tunnel river, either by wading through the river or using a zip-line cable and harnesses, (depending on the conditions). We´ll continue the ascent towards Paso del Viento, along screes, moraines and the Inferior Tunnel Glacier. From the pass, you can appreciate a portion of the Patagonian Ice Field, the origins of Glacier Viedma and the Cerro Mariano Moreno mountain range.
We´ll descend to the “Refugio Paso del Viento” (900m/a/s/l) where we will camp. It is a 7 hour-hike with an elevation gain of 900m from Laguna Toro to Paso del Viento.


We´ll continue the trek bordering Cerro Huemul towards East until we reach “Paso Huemul” (1000m/a/s/l). There are great views of Viedma Glacier during the entire trip! From “Paso Huemul we can appreciate the front of the Viedma Glacier and the homonym lake.
It’s usual to see condors flying near by. There is a very steep descent trough the forest and rocky terrain, down to “Bahía de los Témpanos”. The hike will take around 8-9 hours and we will camp at Bahía de los Témpanos.


The terrain today is steppe, with moderate elevation gain, some rivers and bog areas. Near the end of the hike, we will need to get across the Tunnel River.
Total time 5-6 hours to “Bahia Tunel” . Transfer back to El Chaltén, end of our services.
