Overview

Climb Mount Aconcagua

This is a guided mountain expedition and we offer both the Horcones route and the Vacas Valley route. We normally run one trip per year. Mount Aconcagua at 6962m high is the highest mountain in the Western hemisphere and the highest mountain in the world outside the Himalayas, located in western Argentina near the Chile border. It is one of the fabled Seven Summits, the highest peaks on each of the seven continents. 

There are about 3500 climbers trying the summit each season. The normal routes are non-technical with sections of snow and ice, both following the Northwest Ridge to the summit from the same final camp. The altitude and the weather and the high level of self-sufficiency required pose the biggest challenges, so this is not a climb for the uninitiated. 

This expedition is more physically and mentally demanding than mountains like Elbrus or Kilimanjaro, requiring a good working knowledge of camping, cooking and cold weather survival skills. Fitness is important too; there are porters available, but there is more self-carrying of loads up to around 15 kilos at altitude. The trip is expedition style and the route involves a 3 or 4 day walk-in to base camp followed by two or three high camps before the summit day. We recommend a good period of preparation for Aconcagua and we will help with as much advice as possible. 

This is a great expedition for aspiring mountaineers looking to really stretch themselves and tackle some higher altitudes. The mountain itself is challenging and should not be underestimated but with sufficient preparation and training will be a significant achievement to stand on the highest point of South America.

Mount Aconcagua has two summits, north and south, joined by a ridge called the Cresta del Guanaco which is nearly one kilometre long. Other ridges radiate from each summit, and the whole massif is isolated from other peaks. Shaped like a giant wedge, it has a very steep and massive face to the South and a gentler slope to the North. The huge Polish glacier flows to the East and a series of arêtes and couloirs flank it on the West. The view from the top and from the Cresta is particularly dramatic and well worth the effort of reaching nearly 7000 metres. 

Group Logistics on Mount Aconcagua

The teams are normally between 5 and 15 people, and we use our own guides to lead the trip along with local Argentinian guides if necessary. The guide:member ratio is never more than 1:5 for the walk in and the carrying to high camps and the summit day.

We do expect that our teams show involvement in the jobs of cooking and camping; we do not provide additional staff to do all of this. The success of the trip is in developing the camaraderie and team effort that is the hallmark of any safe trip in the mountains.

The carries are done by the team, with everyone helping to move supplies to the high camps, but there are porters at base camp who can be hired; members can individually or as a team decide to hire porters for their own personal equipment. On average porters cost USD$250 per load carry of 20kgs, but this is dependent on the height/camp they are going to. The company will often assist with providing porters to carry group gear. 

There is a clear policy of what do in the event of a rescue on Aconcagua, the national park rangers are very well versed in how to assist with a descent and there is a helicopter on standby to take people back to the park gate. However there is a clear understanding that any team should be prepared to self-manage any emergency on the mountain rather than just rely on the ranger service. 

How fit do I have to be to climb Aconcagua?

You will need to be in good physical condition. If you have not been to altitude before you must consider that 7000 metres is very high and you will need to monitor your ability to acclimatize, which will require patience and good judgment. Atmospheric pressure is 40% of sea level at the summit but people do not generally use supplemental oxygen for this expedition. Good physical fitness will aid your ability to trek at high altitude and carry a rucksack, assisting your body with it's acclimatisation, and it will of course make the trip more fun if you are not constantly feeling defeated by the demands of the trip.

Train the thigh and calf muscles, and work on lots of stamina training, cardio-vascular work and as much hill walking with a rucksack as possible. You cannot train for altitude anywhere in the UK or Ireland, so concentrate on arriving with the confidence of feeling fit and mentally prepared. Put on a little weight in the weeks beforehand and don’t over-train in case you strain something! 

A gradual approach to training, several hours per week in the gym with a good walk on the weekend, will suffice. Pilates is excellent preparation, as is swimming, step machines, rowing and walking up stairs or hills. Practise also sleeping on hard surfaces since for some people the shock of lying on rock and ice in a tent can lead to sleepless nights. Sleeping tablets are strongly discouraged on a mountain trip because they slow down the rate of breathing, so it is important to give your body the best opportunity to rest. Work on feeling comfortable with a day hike and carrying a rucksack of around 15 kilos. It is also important to get your feet hardened and ready for the trek, since blisters will stop you faster than anything. Remember also that double boots or plastic mountaineering boots are quite heavy and stiff, so practise with them on and comfortable with a pair of thick mountain socks.

Note that members now need to undergo two medical examinations at base camp before being allowed to ascend higher. We strongly recommend that you have a medical before leaving home and discuss with us any pre-existing conditions such as high blood pressure or a heart murmur, which might affect this requirement by the Park Rangers. They do have the power to prevent you from climbing any higher, however in our experience they are very friendly and encouraging and they will help wherever they can to assist with a safe ascent. They do not condone the use of drugs like Diamox, unless needed in an emergency, preferring to advise on diet and a healthy lifestyle at base camp. So for example they will advise against taking salt in your meals. 

Hiking on Mount Aconcagua

Much of the hiking is on scree and rock. Although there are no permanent snow fields (not including the glaciers, which are technical routes), crampons and a walking axe are still required for the higher sections. Sometimes the final thousand metres of elevation is covered with snowfall which can be consolidated into hardpack or ice, and any person contemplating Aconcagua should be prepared for extremely cold conditions and the need for using equipment competently. This means walking safely on crampons and knowing how to use an axe to arrest a slip, and using poles efficiently. 

Summit day is a big mountaineering day, but the terrain never requires highly technical skills. It is a long hard ascent, and there is considerable exposure to the elements and of course to the altitude. The weather patterns will determine if you spend the day mostly on snow, ice or rock, but expect everything and be prepared with correct warm clothing and good double boots.

The most infamous feature to overcome is the Canaleta, which is a gully choked with boulders that is quite unremitting and hard work. Sometimes you will be on rock, other times it will be covered in snow and often is it hardpack and ice, but either way it is important to watch your feet and be able to move safely on crampons. Coming out of the gully, the route traverses the top of a large amphitheatre and ends up on the final ridge to the summit, with classic views over the south face. There is a bit of scrambling to the summit, but it is not difficult.

As ever, the issue will be keeping enough strength in hand to handle the descent safely. It is a long way down! But with adequate supplies of food, hot drinks in a thermos, warm clothes and a back up of safety gear like a sleeping bag for the group, group shelters and a stove for making a brew, everyone should be fine.

Camps on Mount Aconcagua

Vacas Valley route camps

Base Camp at Plaza Argentina is well facilitated and safe. There are huts for eating, medical facilities where everyone needs to get their permit stamped to show they are medically fit for continuing upwards, and it is very sociable.
Camp 1 at 4880 metres has plenty of tent spots and is spread out over a huge area which is often snow-covered. The wind can be strong here but the route is not difficult.There is some running water here.
Camp 2 is called Guanacos Camp and has an altitude of 5400m, and is over the Ameghino col. There is running water here, plus the support of other teams using the same camp space.
Colera Camp at 5970m is the last camp, but sometimes teams try to summit from Guanacos Camp, depending on conditions and strength of group.

Horcones route camps

Base camp at Plaza del Mulas (4600m) is a large tented city at the height of the season with all manner of facilities like bars, showers and souvenir shops. 
Canada Camp at 5000m is a rocky promontory overlooking the whole valley with not much shelter and no running water.
Nido de Condores at 5500m is a huge area with ice pools you can break for water and a park ranger service. 
Berlin Hut or Colera Camp at 5970m can both be used for the summit attempt. There is a 'toblerone' hut at Berlin but otherwise no facilities.

What experience do I need for Mount Aconcagua?

Good teamwork, lots of knowledge about mountains and altitude sickness, and experience of camping at altitude and in cold weather conditions in a tent. We don't recommend Aconcagua to people without experience of multi-day trips, high altitude (at least up to 6000m) and winter camping. 

Technical mountain skills are not vital on Aconcagua, but a good knowledge of camping and self-preservation in cold weather conditions is very important. Erecting tents, using the gas and white gas stoves safely, cooking tasty recipes in the outdoors, packing rucksacks effectively, dressing correctly and managing your personal climate are all skills which have to be learnt and understood. 

Putting a tent up in a gale is not easy and cooking a dehydrated meal for 3 people in a confined space is difficult, as is making water from ice and equally peeing into a bottle inside your sleeping bag! During rest days at base camp and hopefully prior to the expedition there will be time to learn and practise. Good teamwork will come from this and it is the key that gets everyone to the top and back down again. Physical fitness in itself will give people confidence to climb the mountain, but the preparation should also involve reading about the mountain, and working on camping skills. 

We have two pages entitled 'Acclimatising Safely' and  and ‘High altitude treatment’, both of which should give you some excellent knowledge on what is happening to your body up high. This is something that you cannot train for at home and understandably there is sense of apprehension about what will happen. The more you know the less afraid you will be, and the more confidently you can climb the mountain.

When is the best time to climb Aconcagua?

It is best to climb during the official season because the weather is more stable and it is warmer. You are more likely to have longer periods of high pressure bringing good weather. Aconcagua is affected by the maritime weather coming from the Pacific Ocean and storms can come very quickly, along with high winds and heavy snow. When this happens it is possible to wait for several days before there is a change, after which there is likely to be deep unstable snow conditions up high. High season is therefore best, but it is also possible to still get the good weather at the start of the shoulder season in February. 

Also, the necessary logistics are more likely to be available in the high season and shoulder season, for example mules, porters and base camp provisions like meals, showers and so on. The shoulder season is also fairly busy so the facilities will still be there. One downside is that at the zenith of the climbing season, mules and porters are often pre-booked and accommodation facilities full, and the cost of virtually every product, including a permit, is higher.

Itinerary

MOUNT ACONCAGUA ITINERARY

The expedition is 20 days in-country, but this does not include flight times or extra days in-country. Many people choose to arrive a day or so early to acclimatise to the climate and overcome the long flight, and of course some people stay on afterwards to visit the vineyards and enjoy the area round Mendoza.
