Aconcagua Ameghino and Upper Guanacos Route

Tour Description: Season 2015

An adventurous exploration of Aconcagua 6,963 m. We will make a new traverse of the mountain and experience its entire character. Our route via the Ameghino & UPPER Guanacos valley is a new semi wild and pristine alternative to the heavily traveled route of the Horcones alternative.

Only recently open, the Ameghino & Upper Guanacos traverse offer breath-taking views of the neighboring peaks and glaciers. We connect the Guanacos by traversing from camp 1 of the Polish route through the Ameghino saddle to camp 3 of the Guanacos variant, is a very easy and beautiful traverse. In addition this route use all benefits of the Plaza Argentina base camp like permanent Doctor, stationed porter staff, daily mules arrival for any emergency, etc…. this route also offers a gradual approach and climb of Aconcagua, using 3 high camps. During the trekking program we add an extra day at Casa de Piedra to easE up the altitude gain. We believe that an un-hurried acclimatization will offer a safer and more comfortable climb, and a rate of success not possible on other routes.

While this route offers a more gradual ascent of the mountain than other routes, it does not come with out any difficulty. Even with our “double carry” strategy between camps, which benefits us in many ways; participants still need to be able to carry a backpack weighing between 30 and 40 pounds (14-18 kgs.) Carrying these loads becomes harder as we move up the mountain, as we are able to utilize less and less O2 in the atmosphere. However, keep in mind that you will be getting more and more acclimatized as the days progress. These heavier packs will be carried between camps on our portages and moves, sometimes on steep loose terrain. The portages and moves, even with these loads, generally take between 3 and 4 hours to the next camp. Together with a slow steady pace set by your guide and proper use of the rest step it becomes quite attainable. Our schedule, while on the route, is actually quite relaxing. We allow ample time for sleeping and packing up in the morning. You will be eating very good meals and drinking lots of water/juice and hot drinks.

Please take a look at our training program. By following this program you can assure yourself that you will be arriving to S.A. ready for what is soon to become a truly memorable, enjoyable and successful experience, whether this is a one time thing or part of your quest for the 7 summits.
