Aconcagua is the highest mountain in the Western hemisphere, located in western Argentina, near the Chile border. There are about 3,500 climbers trying the summit each year (info from 2002). The 'Normal Route' is non-technical - a walk-up, following the Northwest Ridge. It is the altitude that poses the most problem. That and the sense that this is an easy climb. Every year people die because they underestimate the task at hand. Respect this mountain and you will fare better. You should not attempt alone, you should always have someone watching you. Much of the hiking is on scree. On the Normal and Polish Traverse routes there are no permanent snow fields, but crampons and ice axe may still be required in some sections. If you are fortunate the final 1,000 feet is covered with ice and snow. You can then crampon up this much more easily than when it is loose scree after a dry winter. In, 2008 the Caneleta had hardpacked snow with some icy sections that were easily cramponed making the top section much quicker (in relative terms). Many who neglected to bring crampons were turned back by these conditions. Passports must be shown. Climbers must surrender details of winter ascents they have made in the past to prove they have the requisite experience to climb Aconcagua. They must sign an affidavit assuming all responsibility for the risks of the expedition. They are obliged to list the equipment they will be using. They must show a valid insurance policy that covers rescue and subsequent medical care. The clock starts ticking when you enter the park, whereupon the permits will be marked at the checkpoint in Horcones for the Normal Route or Pampa de Leñas for the Polish Glacier Traverse Route. You will also be presented with bags for trash and your bodily waste – in common parlance, a sh– bag. These are numbered and surrendered upon exit. Failure to do so incurs a $200 fine.

Fly to either Santiago (Chile) then Mendoza (Argentina). Or Buenos Aires then Mendoza. Take the bus to Puente del Inca or Penetentes. The entrance to the National Park is either at Puenta del Inca (normal route and south face). Or the through the Vacas Valley near Penetentes (For the Polish Glacier, Polish Traverse and Vacas routes).

You must go to Mendoza Argentina in person to get your climbing permit. To enter ACONCAGUA PROVINCIAL PARK, you have obtain a permit. You have to fill out the forms personally. Permits are sold EXCLUSIVELY at
SUBSECRETARÍA DE TURISMO på San Martín 1143. Close to Plaza Independencia. Most cabs know where this is. When you apply for your permit in Mendoza you will get a ´banking slip´ from the park office, then go to a nearby "Locatario" to pay your permit fee. Then you will return to the park office and get your ´climbing permit´.The whole process takes one or two hours now, more with high season line ups.

An issue if you go through customs at Santiago airport. There is a good chance that you will have all meat and dairy products from your expedition food confiscated upon entering Chile. Stay in transit and take a short (45 min) flight on Lan Chile or Aerolineas Argentinas to Mendoza, Argentina. This will allow you to keep your food, get your permits, possibly see Aconcagua from the air as they fly close to it at times, and save the 100$ U.S. tax Chile imposes on Americans, Canadians and other nationalities.

If you are entering Chile by bus this will not apply.

Possible food issue. Our climbers had their bags searched in Mendoza Argentina for certain food items. While normally climbers are treated seperately in this respects, as the foreign currency is valued we are not hassled. They conficated some food items such as peanuts and items that had been repacked not in the original packaging. Among the items taken were believe it or not..gummy bears. We think the staff was hungry. I packed all my food in 3-day packs in seperate stuff sacks labled, base camp, camp one, and camp two. These were packed at the bottom of my bag under everything and looked like a hassle to get to and open. Thus the customs were reluctant to get that deep in the bottom of my bag. The people that were searched had packed their food in clear plastic making the customs agent job too easy. So pack your food accordingly to avoid any unnecessary hassles.
