4-day Trek to the “Milagro de los Andes” site in the Valle de las Lágrimas, from El Sosneado

Join a unique 4-day trek to the Milagro de los Andes site, in the Valle de las Lágrimas, along local EPGAMT guide Claudio, from el Sosneado, Mendoza. Discover the history of the plane that crashed into the Andes in 1972, when 16 people miraculously survived.



4 Days

Jan, Feb, Oct, Nov, Dec




  • 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.

Thank you explore-share for a wonderful via feratta experience. We have been wanting to learn for a long time but don't have the facilities in Scotland. The guide Mitja was extremely helpful and knowledgeable, answering all my many questions and providing advice. On the day head to take another group but he quickly arranged another guide Borut, who was brilliant. We had a fantastic morning learning via ferrata at Hvadnik in the gorge. It gave us the confidence to later hire our own equipment and go out in Mojstrana. Altogether a five star + experience. Thank you.

Hello! I have been thoroughly impressed by the service and assistance that explore-share have provided the past couple years in helping to plan my trip to the High Tatras in Poland. I really appreciated the flexibility that they provided in allowing me to rearrange my trip twice owing to covid. They were responsive and communicative throughout. This trip was part of my Stag weekend celebrations and explore-share connected me with an outstanding guide in the form of Marcel - he was an excellent recommendation and we really enjoyed our guided hike in the High Tatras with him. Marcel was an outstanding professional, placed a high focus on preparing well and staying safe, and was also a great guy! Highly recommend. Many thanks and best wishes - Richard
