The road that marks the history

These extensive valleys , interrupted by some solitary mountain refuge. The towering rock walls. The irregular peaks by the white glaciers. Everything is still, as in a painting, being us the main characters  of that painting.


The idea is to enter into the Andes  climbing up a Valley and crossing the Andes by the same place where one of the armies of the Gral San Martin has crossed 200 years ago...An experience that is not easily forgotten.




Crossing expedition (connecting Argentina with Chile).We will take our backpacks and general equipment will be carried by carrier animals . Accommodation on wild  camps and occasionally in mountain refuges  (without the comforts of a campsite) in the mountains.




Here is the route planned for our program, but the exact route and  choice of alternative routes are subject to different factors such as weather conditions and group evaluation by the Guide.


Day 1 (Saturday): Meeting at  Tunuyán in the morning.  we prepare backpacks and we will move up to the Refugio Portinari National Gendarmerie. Registration AT migration (bring ID card and PASSPORT). We will start walking to the Scaravelli shelter. Overnight.

Walking time approx. 4 hours.


Day 2: Day of relax , acclimatization and short walks.  We will move one hour to the next camp in West direction and we will gradually climb up the mountains towards the Portillo pass.


Day 3: Early breakfast  to take advantage of the an intense day: climbing up to 4300 MTS., we go through Paso del Portillo, from where the view is incredible: mountains and glaciers more than 6000 meters down to another Valley, still in Argentina, to spend the night at the great refuge Real de la Cruz, built more than 50 years ago in a beautiful valley.

Walking time approx. 10 hours.


Day 4: New day of acclimatization, essential to be ready for the Great Cross. We can enjoy either a day of reading and bath in the River or a new ascent  to over 4500 meters.


Day 5: Again we get up early to take advantage of the daylight. Our goal is to get  closer to the international pass, for this purpose, we will take a large and beautiful valley, step by step, until we reach Paso de las Ovejas, where we set up camp.

Walking time approx. 10 hours.


Day 6: Key day, we finally cross to Chile. We continue climbing a couple of hours until the border landsmark. Photos, hugs and a snack to regain strength. Then, we will began to go down, but this time in Chilean land. We camped at Pozas del Yeso where you can enjoy its natural hot springs. Walking time approx. 9 hours.


Day 7 (Friday): Breakfast. Transfer to San Gabriel, and from there to Santiago de Chile. On this day we will return by bus to Argentina. End of our services. Buses arrive to Mendoza. Those who prefer can stay in Chile to enjoy one more day. Consult.


Optional: continue with us in the following mountain program . Consult.


Demanding trekking program but without much weight since the carrier animals take care of  the general equipment .
