The scenic mountain village of El Chaltén, in Argentina, features mountaineering options for all levels. I am offering a 3-day tour to the summit of Aguja Guillaumet. If you are looking for a stunning alpine adventure, then join me!

El Chaltén is located in the Santa Cruz province in the Argentine Patagonia. It lies at the foot of two impressive multi-peaked mountains: Cerro Torre and Fitz Roy. Aguja Guillaumet (2579m), part of Mount Fitz Roy, is usually the objective for those climbing in this area for the first time.

On this 3-day adventure, you will face the particular terrain and the strong winds of El Chalten, heading up an exciting line to Aguja Guillaumet. We two possible routes that we can take: Couloir Amy and Fonrouge-Comesaña. We will choose the best option according to the snow/ice conditions, and your skills.

Couloir Amy, on the east side of Guillaumet, was first completed 1968. It has a total distance of 450m, 60º snow/ice slopes, and a 5.8 climbing difficulty. On the west face, we find the legendary Fonrouge-Comesaña, with 600m, pitches from 5.4 to 5.9, and an amazing pitch of 5.10b. Both routes share the last 4 pitches.

From Aguja Guillaumet, we will enjoy breathtaking views of a unique alpine landscape dominated by the Andes and the Southern Patagonian Ice Field!

Please keep in mind that this trip does not require alpine climbing experience. However, if you have some, especially in rock climbing, it will help a lot. In addition, these are all physically demanding days, so you should have a good fitness level.

So, are you up for an awesome mountaineering experience in the Andes? Then come to El Chaltén, at the Argentine Patagonia, and reach the top of Aguja Guillaumet!

And if you feel ready to climb to the summit of Fitz Roy, take a look at this Fitz Roy 5-day program.

IFMGA/UIAGM Mountain Guide from Chile

I was born in 1990, and I always been surrounded by mountains, with family and friends in the Andes.

I did the first Chilean ascent to Cerro Torre via Ferrari route, four ascents to Mt, Fitz Roy, more than 12 to Torres del Paine and the first alpine traverse of the three towers.

I also climbed in the Himalayas, Yosemite, and other Andean countries such as Argentina, Bolivia and Peru.

I did the IFMGA/UIAGM aspirant course in 2017 in Bolivia, and completed the AIARE level 2 avalanche training.

I work together with my brother Juan (we are the Señoret Brothers). Contact me if you want to discover the most beautiful mountain spots in Chile!

What people are saying about Cristobal



Everything was great- we lucked out and had good snow!



Cristobel was a very knowledgeable guide and he provided a good level of encouragement to push me through hard sections of climbing rather than letting me give up. Unfortunately, my original guide for two days of climbing was unable to make it and so I was rebooked for 1 day of climbing with Cristobel. What was upsetting about this was that it was more expensive to complete 1 day of climbing compared to the two days I was originally booked in for. I ended up having to pay more money for half the climbing. I think Explore-Share could improve by having a more consistent price structure for the guides, or at least being clear about why one guide is more expensive.



Great guide. Picked a well-rounded spot for a new group, with numerous options. Understanding of our lack of time at altitude. Great guy.



Excellent day at Portillo with Cristobal. He gave us several options in a planning session the night before. He also communicated well on the day of about current conditions and what we were seeing. We ended up doing a secondary objective due to what we saw in the field.



We had a great trip with Cristobal Senoret in torres del paine!  He was very knowledgeable and helpful.  Beautiful backcountry.
