Aconcagua, the “Stone Sentinel”, is located in Argentina near the border of Chile, and is the highest mountain outside of Asia. We climb a less traveled route that allows for more acclimatization, and while we may use our ice axe and crampons occasionally, this climb does not require ‘roping up.’ Climbers have the option to hire porters to assist with load carrying, as Aconcagua can be a very demanding high altitude climb.
Madison Mountaineering offers the highest standard in climbing Aconcagua by combining expert guides, a well thought out strategy, and excellent support throughout the expedition. Our guides are very experienced leading expeditions on Aconcagua, and spend days before hand organizing the food and equipment for the climb. Although we do not rope up, Aconcagua is a very serious undertaking. Our approach is to properly acclimatize and then attempt the summit with enough extra days built in for bad weather, whereas many climbers try to rush the ascent and are turned around by altitude illness or high winds that prevent reaching the summit when time is limited. We have a very close relationship and daily communication with our Argentine outfitter who provides services such as the mules that transport our gear to base camp, our own private dining tent in base camp, and the porters who are available to assist us transporting gear to our high camps. We keep our teams small, and ensure that climbers have the best chance to reach the summit while remaining safe. Garrett Madison has reached the summit of Aconcagua on nearly each of his 11 expeditions, and has perfected what he believes is the optimum strategy for leading a team to reach the summit.
We begin on the eastern side of the mountain, by trekking along the Vacas River to Plaza Argentina base camp. From here we ascend the non technical false polish and then upper Guanacos route to our high camp. On summit day we climb to Independencia refuge, then traverse the western slope, ascend the Canaleta, and reach the summit ridge leading to the highest point in the Americas. We descend into the Horcones valley and exit out of the western side of Aconcagua, nearly circumnavigating the entire peak.
Prerequisites: Climbers should have trekking or back packing experience. Technical training in how to use ice axe and crampons is a plus, but not necessary as we will review these skills once on the mountain. Top physical conditioning is important as this is a strenuous climb at high altitude.
