Climbers at Nido de Condores...
Sunset and climbers at Nido

Aconcagua, the highest mountain outside Asia as well as the highest on the American continents is located in the mid-west of Argentina. It's surrounded by a lot of interesting peaks and the national park they're located in attracts about 10 000 climbers and hikers every year. All the peaks belongs to the longest mountain range in the world - Los Andes. This particular part of the range is called The High Andes.
As the park (read Aconcagua) attracts a huge amount of people every year there's a permit fee and strict park regulations to follow.

There is something of interest for all kind of nature and mountain lovers in this park. Hikers go their for easy day treks and world class climbers can find their Eldorado on some of Aconcagua's south face which offers a lot of routes of high difficulty.
Aconcagua is also one of the very popular Seven Summits (the highest peak on each continent) and as the normal route to its summit is very straight forward climb, it's a feasible target even for a well trained weekend adventurer.

Most climbers going to the area have their minds 100% set on the Big One, but there are many other peaks which offers interesting climbing. Some are used as acclimatization peaks, some as separate targets. The nature in the park is stunning and it's well worth a visit even for non-climbers.

Aconcagua National Park

 Parque Provincial Aconcagua...
Close to the entrance of the park

For all other mountains in Argentina a very simple rule applies: Pick a peak, go there and climb it.  This is not the case with the peaks within the borders of the Aconcagua National Park. First of all you need a permit, which can be bought in the permit office in central Mendoza, the capital of the province with the same name.

More info on this:

  • The excellent Aconcagua page on Summitpost
  • The official web site.

  • When you have your permit you can either go straight for the park and attempt the peak all on your own or, more commonly, contact an organizer who'll arrange all the details, such as transport, mulas, base camp support etc.

    There are two main valleys in the park and a huge majority use these to reach the foot of Aconcagua. The Horcones Valley on the western side of the peak takes you, via Confluencia to Plaza de Mulas and the normal route. The Vacas valley on the eastern side of mountain takes you to Plaza Argentina, which is the base camp for "The Polish Glacier side" of Aconcagua.

    See map.

    The normal climbing and trekking season is from December to mid March.

    A lot more information about this can be found on Aconcagua page.


    Bonete and the other...
    Plaza de Mulas

    The camping is restricted in the park. You're obligued to stay in the official camp spots along the way to the peaks.

    On the walk in - Horcones Valley/Normal Route:
  • Confluencia. A large camp 1-3 hours from the park entrance. It's huge and usually there are a loads of people around. Large mess tents, sleeping domes and restaurants. The water is said to be a bit too rich in magnesium and some people experience light stomach problems from drinking it.
  • Plaza de Mulas. The base camp. A large area with anything you want (and don't want) can be found here. Internet, restaurants, a techno tent (!), places to rent anything from guides to gloves and porters and tents. A restaurant and hotel is located about 15 min away. The park rangers has a hq here and there's also a little clinic.

    If you for some reason is unable to reach any of the camps, the rangers of the park usually allows you to camp in between. A valid reason, such us altitude sickness or a sore ankle is usually accepted, but some zealots have told climbers to rent a mule to go down or up to the next camp.

    Higher up on Aconcagua you can basically camp anywhere, but if you're in a large group you may be told to use the official camp spots.

    Independencia refugio
  • Camp Canada. At 5050m is a wind swept place with quite limited space. Water can be a problem here. An alternative camp is to be found a bit S of Canada proper.
  • Camp Alaska at 5370m is a spread out place and tents are scattered over a large area. Most climbers gives this place a miss as it can be tricky to find a flat spot.
  • Nido de Condores. 5500m. A large good camp, which usually have either running water, or lots of snow to melt. The park ranger's last outpost. The place from which about 40% of the climbers attack Aconcagua's summit.
  • Berlin. 6000m. Three small refugios in various condition offer a place to sleep if you for some reason don't want to use your tent. Many complains about too much junk and excrements around this camp.
  • Colèra. A bit over 6000m. Located off the main trail to the N. In a better and cleaner location than Berlin, but a bit hard to find for those who don't know the area.
  • Ameghino ridge. 6250m. Not an official camp spot, but used quite often. Can be very windy, but offers a short way to the summit and fantastic views to the north.
  • Independencia at almost 6400m is an old wrecked refugio, which in itself offers little more than an emergency place to sleep. High and cold.

    The weather

    A storm rolling in
    El viento blanco. The flat...
    Viento Blanco clouds
    Aconcagua is the highest peak in the area and therefore it attracts bad weather. If there's only one single cloud on the sky, it's a fair chance it's hanging over the summit of Aconcagua. Weather changes are swift and sometimes very dramatic. A clear day can transform into a windy and cloudy hell in a matter of an hour. The most feared and infamous condition is the Viento Blanco (white wind).
  • Usually the forewarning comes in the shape of an ominous looking cloud formation over the highest peaks. It looks like a soft cotton cap, which is constantly shifting in shape. When you see it - beware! A storm with very fast temperature plunges and ferosious winds are usually around the corner. If the storm breaks, heavy snow usually follows. The really rough storms usually arrive from the west.

    That said, the area can also be warm and nice and the weather systems usually holds for some time. When it's warm, don't be surprised you don't have use for many of the cold weather items you brought. I have seen summiteers in only wind proof fleece jackets and without gloves.

    Another common weather type is the clear day, with fresh and chilly air and high winds. In general this type of weather is good for climbing, as it's a solid and not so quick changing weather pattern. Be prepared for cold climbing though.

    The surroundings

    When leaving Mendoza you're traveling from the hot flat lands of Argentina, into the dry mountains of Los Andes. An almost desert area is passed and the little town of Uspallata is the last oasis with some real vegetation in terms of trees.  The gorge leading to the national park and later the Chilean border has steep mountain sides with very little greenery. At the entrance of the park there are still some grass, but after only a couple of hours walking you can't spot a sign of flora. It may sound like a dull landscape, but the colors of the surrounding peaks well makes up for the lack of trees, flowers and plants.

  • The sights of mountain sides in red, gold and sometimes almost green makes the walk in a beautiful experience. When getting close to the base camp, (Plaza de Mulas) the landscape shift quickly to a more alpine experience.  
    Penitentes in the way to C1....
    Penitentes fields, small melt-off rivers, glaciers and snow capped peaks appear all around you. The valley terminates at the Cuerno-Horcones wall of peaks with large glaciers.

    Rock climbers don't have much of a treat here, as the rock in general is quite rotten.
