A touching story…

October 13rd 1972: A Uruguayan plane that carries 45 passengers to Chile, most of them students and rugby players, crush into the Andes.

Twelve of them died because of the crush.

The survivors had to carry on living in hunger and trying to tolerate the fearless mountain , 30 degrees below zero during many nights.

They try to resist with a limited reserve of food they found within the wrecks of the plain, as they wait to be rescued. Their faith decreased when they heard on the radio that the rescue had been called off due to the belief that none of them had survive.

Finally, tired of the low temperature, the threatening avalanches, the increasing anguish for the dead friends and the loss of hope to be rescued, two of them decide to cross the huge mountains to reach for help.

This is how in December 22nd of 1972, after 72 days of isolation, the world took notice that sixteen passengers from that plane had passed away due to the climate of the mountains, of the Andes.

This event was later told by the survivors, in a book and, later on, it turned to a movie “VIVEN”, which delivered this story to the world.

Today, the journey starts at this breathtaking location.

And we invite you to visit this place, as you go over this story….




Day 1: We arrive to San Rafael at 9 am and we headt to El Sosneado by bus from where we will take the route to the west that leads us to the Soler refuge and Gendarmeria Nacional. As we pass by the abandoned thermal hotel from El Sosneado we will arrive to ranch Araya where we will have lunch. 

First stage: we will cross the Atuel river and trek for about four to five hours to arrive to the location where we will have another stream crossing called Arroyo Rosado. After we organise the camp, we will have dinner and spend the night at this location.


Day 2: We begin the second stretch to the next camping, near the Barroso stream, it will be a 4 hour trekking. As we cross the stream we set to prepare the camping and spend a quiet afternoon in the surroundings . There we will have dinner and spend the night.

Plan B:If we get late on the first day to Puesto Araya, we will camp by the Atuel river and on the following day we weill have a long trekking to El Barroso.

Day 3: This will be a very hard day as after three hours of walking, we will cross Las Lagrimas river and then we will ascend for two hours and half to the site where the remmants of the plane are situated (3600 AMSL). We will stay in silence in tribute to the victims.. Descent. Crossing of the river. Lunch. Descent to camp. Lunch, farewell dinner and overnight


Day 4: After Breakfast we will disassemble the camp. We will walk back to point Araya where we will have lunch. Then, we will return to El Sosneado and Malargue. End of our services.

Difficultie´s Graduation

Mochila: Peso / Duración de la Jornada.

Exigencia Física

Técnico: Dificultad en el Terreno / Equipo.

Fortaleza Psicológica

Exposición a la Altura

Backpack (M)

This point has to do with the weight that we must carry in our backpacks. Trekkings or crossings where we have pack animals allow us to bear less weight on our backs. And the multi-day journeys in Patagonia (without the option of having pack mules) generally make us carry more weight, especially in the early days.

20% Up to 5 Kilos: Short excursion walks / Trekking Talampaya

40% Up to 8/10 Kilos: Round-trip trekking / Vallecitos 3 and 4-day programs

60% Up to 12/15 kilos: Crossing trekking with porting / Crossing of the Andes Paso Portillo

80% More than 15/18 kilos: Cross-country trekkings with little or no portage / Trekkings in Patagonia (Paso Vuriloche, PN Lanin or Nahuel Huapi, etc)

100% More than 25 Kilos: With a lot of equipment on top and little or no porting / Continental Ice

Fitness (F)

We consider physical demands to the wear that we can suffer both aerobic (climbs = possible shortness of breath) and muscle (resistance = many hours walking) and of legs and joints (descents = knees / ankles).

20% half a day or less with little unevenness.

40% more sustained slopes and longer days in the activity. 2-3 days / more than 6 hours per day.

60% Long ascents and descents with a longer duration. Ascents to more than 4000 meters in the central mountain range / intense 4-day trekking (Uruguayan plane)

80% Important work of legs in resistance. Very long days. Very long day ascents (Lanin - Domuyo) or more than 5000 meters. Ice courses.

100% Maximum demand. Aerobic work and constant effort on legs. Continental Ice, Aconcagua, mountains of more than 6000 meters.

Technical (T)

The technical difficulty is mainly based on the terrain. How much can it cost us to climb a slope, if it is very steep or if we have to use our hands in some section (simple climbing), both in rock and snow-ice, or materials such as crampons and pegs in other ascents.

20% flat land

40% trails with moderate ups and downs. General crossing trekkings . Sierra de la Ventana, Córdoba, Patagonia, Cuyo, north, others. Classic ascents

60% Steeper slopes and trails. Possible use of crampons. Domuyo, Cordón del Plata, Cordillera Central.

80% Mixed terrain, with snow or ice. Alvear, Lanin, Tronador. Bolivia, Peru.

100% Highly technical terrain. Glacial transit and climbing in sections. Hill climbing with sections on slopes of more than 60 ° inclination

Psycho (P)

We maintain that this point, the psychological factor, represents a relevant factor. Each one needs a factor of conviction, confidence, self-control and will power to achieve a goal. And depending on the attitude with which we face distances, slopes, terrain and many other objective factors, we can achieve performance with very different results.

20% We will not be much affected.

40% This is a normal level of attention.

60% We require more motivation, enthusiasm and concentration.

80% The activity will require us to be very connected and convinced.

100% Maximum control and emotional-psychological performance.

Adventures (A)

It is the factor that, the height above sea level, influences us depending on the activity we carry out. Managing and overcoming symptoms caused by altitude is the key to this point

0% + sea level.

20% Up to 2000 masl.

40% + 2000 masl.

60% + 4000 masl.

80% + 5000 masl.

100% + 6000 masl.
