Our Aconcagua Ameghino Valley and Upper Guanacos traverse route, with porter availability, is presently the BEST route on the Aconcagua. Our long-time favorite route on Aconcagua, the Guanacos Valley route, is presently closed (the lower part of the route) to expedition access. We will be using our Ameghino route to approach Aconcagua while this closure is in effect. Our Ameghino/Upper Guanacos traverse expedition uses part of a previously established route (a.ka. Relinchos Valley ), named after the striking Ameghino Peak, (19,530’), which surrounds the route. This route joins up with the upper section of our Guanacos route. Our Ameghino route is cleaner and less climbed than the over popular Normal Route of Aconcagua. This route, just as our Guanacos Valley route, has a higher success rate due to a longer approach (than the Normal Route) allowing more time for acclimatization. The Ameghino route is non-technical, and porters are readily available, if needed, at Base Camp – Plaza Argentina, for carries to the higher camps, and for the descent.
Above Camp One of the Ameghino route, we reconnect with the upper portion of our long-time favorite Guanacos route, offering our clients the benefits of both routes. The benefit of the upper portion of the Guanacos route, and the benefit of the less remote Ameghino Base Camp (Plaza Argentina), allowing our expedition parties the comforts of an established base camp, our own chef, access to porters, a medical doctor, and more, none of which are available at the lower Guanacos Base Camp.
The Aconcagua Ameghino Valley and Upper Guanacos Traverse begins with the same approach as the Guanacos Valley for the first 2 days. On the third day, we take the beautiful Ameghino Valley up to Base Camp. This eastern approach to the mountain is not as heavily traveled as the Normal Route. After three days of spectacular, colorful, high desert scenery, we reach our deluxe Base Camp - Plaza Argentina, at 13,800’.
Above Base Camp, we meet up with our traverse, then to the summit of Aconcagua, and our descent via the Normal Route. We will circumnavigate Aconcagua, traveling several different valleys; the Vacas, Ameghino, Guanacos, and Horcones Valleys. We experience an entire spectrum of Aconcagua, passing four spectacular faces of this tremendous mountain. On our 3-day approach to Base Camp, on the east side of Aconcagua, mules carry our gear, stopping each night along the way, so we have access to our gear. After summit day, we descend the north side of Aconcagua via the Normal Route, to Plaza de Mulas Base Camp. Mules carry our gear from Plaza de Mulas Base Camp to Penitentes, while we hike out to civilization with a light pack.
Note: The Aconcagua Park Authorities have closed the lower Guanacos Valley until further notice. We hope to see this route reopened. This route closure does NOT affect our Ameghino / Upper Guanacos Traverse Expediton.
Which to choose, Guanacos or Ameghino?
Our wisest advise here is; choose our Ameghino Valley and Upper Guanacos Traverse Expedition. It is the best choice at the moment, for a non-technical route on Aconcagua. If the lower Guanacos Valley reopens to expeditions, we will contact our clients and discuss the option of using the lower Guanacos Valley approach. The trip price is the same for both routes. This guarantees you the best possible choice of routes, if access to the lower Guanacos Valley opens up by your expedition start date. Our Polish Glacier Expeditions will approach Aconcagua via the Ameghino Valley for now. If the lower Guanacos Valley opens, we will approach the Polish Glacier via the lower Guanacos Valley route.
