9-day Ansilta Peak Hike in the Andes

Ansilta Peak Hike
Ansilta Peak Hike

Join AAGM certified mountain guide Anibal on a stunning week long climb of the Ansilta Peaks located in the heart of the Andes!


9 Days

Jan - May, Oct - Dec




The Ansilta Peaks lie in the heart of the Andes mountains in the Argentine San Juan province. 7 peaks make up this chain of mountains whose altitudes range between 5116 and 5886 mts. Consequently, each of these peaks provides numerous trekking routes to discover the beautiful Andean landscapes. On this 9-day climbing expedition, we will guide you to some of the stunning summits of the Ansiltas!

We will begin with a 6 hour drive from Mendoza to Los Morrillos. Los Morrillos is a beautiful natural reserve in San Juan. Furthermore, it is also an important archeological site with a strong indigenous heritage.  From Los Morillos, on day 2,  we will head to a stream in the mountains called Arroyo Fiero.  Then, after a night of camping out in nature, we will continue up to the Ansilta 3 and 4 base camp. Because we will be steadily ascending up the Andean mountains, we will take a day to acclimatise before attempting the first summit of Ansilta 4. Then, we will take a day to recover from this exhilarating climb. Once we are back on our feet, we will attempt the slightly more demanding summit of Ansilta 3. Finally, we will wrap up our tour by walking back to Los Morrillos and then driving back to Mendoza. 

Because these are challenging ascents, we require a good fitness level. However, we will be there to guide and help you every step of the way, and we also contemplate acclimatisation and rest into our schedule. Furthermore, all the hard work is well worth the effort as we will enjoy a unique experience with stunning landscapes all around us!

Ready to climb up this breathtaking group of mountains in the heart of the Andes? Then book your place now and join me on this exhilarating 9-day Ansilta Peak Climb!

I was looking for a local guide for a hike I was planning and came across Explore-Share. They seemed to have good reviews and so decided to give them a try. The experience was very positive and completely happy with their service. I will be using them again for next trip.



Easy to set up and find the perfect trip. Informative site that is easy to use. Guides are all great to work with and communicate all arrangements needed. As simple as can be!



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.
