Come to the beautiful south of Argentina and join a 1-day trek to Achen-Ñiyeu Volcano. Cristian, an AAGM certified guide, will lead you.


1 Day

Jan - Apr, Oct - Dec


I want to invite you to a 1-day trek to the Achen-Ñiyeu Volcano, in the beautiful Patagonia! Come and discover this amazing place in the south of Argentina.

First, we'll skirt Laguna Verde, 65 km from the city of San Martin de los Andes. Then, we'll enter a forest of colihues, cohiues and other native species. We'll walk along the trail until we see the Achen-Ñiyeu volcano in front of us.

The trek continues through volcanic sand and remains of slag, lava flow turned into rock. It was channeled through an ancient glacial valley, about 450 years ago.

The entire trek will take us about 8 hours. Once we're at the base of the volcano, we can climb to its summit. It will take us about 1.30 hours. Or we can either go to Cascada del Portezuelo, a beautiful waterfall.

Then, we'll return by the same path, but now with the spectacular sight of the Lanin Volcano in front of us. It's the most stunning mountain in North Patagonia.

So contact me if you have any questions about this trek to the Achen-Ñiyeu Volcano! And if you're looking for a more challenging adventure, you can also check my 1-day hiking ascent to Cerro Chapelco!

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.
