Trekking to Uruguayans plane - ALIVE


A story that shocked the world...

On Friday October 13th 1972, a Uruguayan plane, carrying 45 passengers to Chile, many of whom were students and players from a rugby team, crashed in the Andes Mountains.
Twelve died from the impact and those who survived had to endure, among other things, the fearsome Cordillera with its thirty degrees below zero at night and the scarcity of food reserves.
Finally fed up with the very low temperatures, the threatening avalanches and anguished by the continuous death of their companions and the slow wait for rescue, two of them decide to cross the immense mountains to reach Chile.
On December 22nd of that same year, after having remained isolated from everything for 72 days, the world learns that sixteen defeated death. These events gave rise to the book and later to the film "Alive". Our tour invites you to visit this miraculous place that, on the other hand, has a very important landscape content.

Difficulty 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

Physical (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.
