4 Days

  • Trek to the place where survivors resisted for more than 2 months
  • Go on a challenging trek to a unique sanctuary in the Andes
  • Learn more about an inspiring and touching story


This 4-day trek starting in Mendoza takes you to the “Milagro de los Andes” site, the crash site of the Uruguay AF Flight 571 in 1972, with 45 passengers onboard, most of them rugby players. The accident was later told by survivors in a book, and immortalized by the 1993 Ethan Hawk/John Malkovich film “Alive!”.

This trip is a tribute to those brave survivors. The plane was flying from Uruguay to Chile, but it crashed in the Andes Mountains. Twelve passengers died and the survivors resisted there for more than 2 months, experiencing thirty degrees below zero during the nights, hunger and death.

They tried to resist on the little food reserves they had, waiting to be rescued, but they lost hope when listening to a radio they learned their search had been abandoned. Finally, desperate because of the freezing temperatures, the menacing avalanches and distressed by the continued death of their companions, two of them decided to cross the immense mountains to reach Chile.

This is how on December 22, 1972, after having been isolated for 72 days, the world found out that sixteen of them had defeated death in the Andes. This was called the “Milagro de los Andes”(the Andes Miracle). This trekking tour takes you to the place of the crash, today a sanctuary.

We will meet in the city of Mendoza, and from there, we will transfer to El Sosneado village, where our adventure begins. You can check the day-by-day itinerary below. 

Bear in mind this is challenging, truly demanding trek, so you need to have an excellent fitness level to join us, as we will be trekking for a total of 12 to 13 hours on the third day, with an elevation gain of about 1000m. We will be camping in the mountains, and trekking on rock terrain, over snow or ice during some sections, although without technical difficulty.

If you are in for this unique trek, just contact us and book your place. Come join us for a once-in-a-lifetime experience in the impressive Andes.
