Native Argentine AAGM certified mountain guide Tomás Ceppi leads this expedition to the summit of Aconcagua's lesser known neighbor.



13 Days

Jan, Feb, Mar, Apr, Nov, Dec




  • Reach the summit of Cerro Mercedario (6770m)
  • A group expedition with a personalized feel and 3:1 participant to guide ratio
  • All meals, accommodation and group camping equipment is included


Cerro Mercedario has gained popularity in recent years. At 6770m, it is one of the top 10 tallest peaks in the Andes. Situated in La Ramada mountain range, Cerro Mercedario is located 100 kilometers north of Aconcagua.

Though not as high as neighboring Aconcagua (6960m), Cerro Mercedario has a charm all of its own. A lesser known peak, it is an ideal choice for mountaineers in search of a challenging alternative in the Central Andes. If you have already climbed Aconcagua, or prefer to stay away from the crowds, I highly recommend Mercedario.

On this expedition, we will ascend Cerro Mercedario via the normal route, or Ruta de los Incas. This route became known as “The Incas’ Route” after a group of mountaineers discovered Inca ruins near the summit in the 1970s. We will retrace the steps of this ancient civilization as we make our ascent.

Throughout the expedition, we will stay at huts, base camps and high altitude camps as we make our way toward the summit of Cerro Mercedario. We will be spending the night at the Laguna Blanca Hut, Guanaquitos Base Camp, Cuesta Blanca Camp, Pirca de Indios Camp and La Ollada Camp. You need only bring your personal camping equipment as I will provide you with a tent. All group camping equipment and meals are included as well.

This is your opportunity to summit one of the lesser known of the Andes’ greatest peaks. Don’t miss it! You’ll quickly realize why Cerro Mercedario is becoming a rival for Aconcagua within the mountaineering world.

About the guide

Mountain Guide - EPGAMT - Argentina
I was born in Patagonia, Argentina and formed at an early age as a climber in the Nahuel Huapi National Park. Currently I completed a large number of rock and ice climbing routes, backcountry skiing and ascents in many mountains around the world such as Mt. Lhotse (8.516 mts.), the 4th highest peak in the world, without using supplemental oxygen (May, 2012).
I'm a certified Mountain Guide from the EPGAMT and a member of the Argentinian Mountain Guides Association (AAGM) and work on Mt. Aconcagua, which I had repeatedly ascended, as well as in other peaks in the Central Andes, Patagonia, Chile, Peru, Bolivia and in The Himalayas in Nepal.
During the winter season, I practice backcountry skiing, mostly on the volcanoes in Patagonia, where I can offer you different adventures, according to your level (beginner, learner or advanced learner).
I feel very privileged to work as a mountain guide, to do the job that I love, and to be able to share it with people that have the same passion.
Join my expeditions and I will provide you a high standard of safety and personal attention!

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
