Join Rodrigo, certified IFMGA guide with 30 years of experience, in this 20-day untouched and unique Guanacos Valley Route to the top of Aconcagua.



20 Days

Jan, Feb, Nov, Dec




Let me take you to Aconcagua Summit through the Guanacos Valley Route, the last untouched path on this great mountain!

After more than 25 years hiking around this area I've discovered the best route to go up. Because of its progressive elevation gain between camps, the acclimatization of this route is more efficient. And this is the key to success in climbing the highest peak in the western hemisphere.

This 20-day Guanacos Valley Route is a non-technical route that goes through Vacas, Guanacos and Horcones valleys. Therefore, you'll be able to see the four different faces of Aconcagua.

During the hike to Plaza Guanacos Base Camp we'll gain altitude gradually. And because this route takes a path not known by most, you won't see other climbers in the way up. Instead there is a big chance of seeing a lot of wildlife.

Another unique feature of the Guanacos Valley Route are its incredible sights. We will see glaciers contrasting with high altitude deserts during the first couple of days. Also in Camp I we'll see Penitentes, a unique snow and ice formations created by the direct sunlight.

So trust me when I tell you that I've found in this Guanacos Valley Route the best approach route to Aconcagua. And contact me if you are keen to try it!

NOTICE: Unfortunately the Aconcagua Park Authorities closed the first part of the Guanacos Valley Route until further notice. Although we are working hard to reopen it, I offer you to check my trips to Aconcagua through other routes: the first -and most similar- route is Aconcagua Summit through Ameghino Valley and the more technical and advanced route is the Polish Glacier Route to Aconcagua.

What people are saying about this trip



I did a 20 day climb of Aconcagua with this company. The guides were excellent and made the trip as enjoyable as possible. We had hot meals every evening and morning. Aconcagua is a hard mountain and it takes a great deal of effort to reach the top. The guides at Patagonicas are committed to each client's safety on the mountain. I would recommend them over any other company on the mountain.
