Aconcagua Expedition

Aconcagua summit at 6962m high is the highest mountain in the Western hemisphere and the highest mountain in the world outside the Himalayas. Mount Aconcagua, the Stone Sentinel, is most worthy of your attention, being the second highest of the Seven Summits.

About the expedition

This is a Personally lead 19 day expedition by Jason Black on the Vacas Valley route. The route is non-technical, there is no need for years of experience of climbing on rocks or ice. Despite its lack of technical challenge, there is still a high level of fitness required. 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 Mount Elbrus or Mount Kilimanjaro, requiring a good working knowledge of camping, cooking and cold weather survival skills. Fitness is important 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 Aconcagua summit day. We recommend a good period of preparation for Aconcagua and i will help with as much advice as possible.

Stand on the highest point of South America

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. It can be dangerous but there is a procedure for rescues off the mountain and the Rangers are very helpful, plus there is a helicopter service that will take people down to the gate.

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 Aconcagua 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

Aconcagua Facts

Our expedition teams are normally between 5 and 10 people. Jason Black is the expedition leader and is currently the world record holder on Aconcagua setting the fastest traverse in history, 18 hrs from Argentina base camp to summit to playa de mulas base camp.
The guide to member ratio is never more than 1:5 on Aconcagua.

We do expect that our teams show involvement in the jobs of cooking and camping above base camp, so experience of camping and cooking in a tent is important. The success of the trip is partly in providing good personal preparation for every member, and 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 Aconcagua porters at base camp who can be hired.

In the event of a rescue on Aconcagua, the national park rangers are very well experienced in how to extract members and a helicopter on standby 27/7. 

Climbing in Mount Aconcagua

Much of the Climbing 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

Aconcagua is the tallest mountain in the Americas and should not be taken lightly. Hundreds of people each year have to turn back due to altitude sickness. Therefore, it is important to have a detailed understanding of the risks associated with high altitude trekking and how the body deals with high altitude.

Climbing insurance is vital for Aconcagua. If an accident or incident should occur that requires immediate medical assistance and evacuation you will most definitely want adequate trekking insurance that can cover the costs of air ambulance and treatment. Make sure you have insurance that covers you for any travel related risks, like lost, stolen, damaged or delayed baggage; interruptions and flight delays and tour operators default.

  • Insurance – Visas – Flights

  • Do i need Travel Insurance

On any trip its advised to take out travel insurance appropriate to the countries you are visiting and what you will be doing when you get there. It is important to take out your policy as soon after booking your trip as possible. If you need to cancel for a legitimate reason then your trip costs and flight costs will be covered. 

Our recomended Insurance provider is

Irvine Cambell travel insurance policies are sold for an individual trips or as annual cover if a frequent climber.

Some companies sell an annual travel insurance policy as part of a package which might include house and car insurance, but in our experience those travel polices may not cover the sorts of activities that we provide like trekking at altitude and mountain climbing, but they will cover holidays like wildlife safaris. Do always check that what you buy covers what you are planning to do. 

Areas to be aware of. 

Coronavirus update: since the global pandemic and the introduction of travel corridors and advisories against travel by the FCO in Ireland and other Governments, insurance companies have adjusted their policies and some are offering cover for travel to countries which are on the FCO list for ‘all but essential travel’ and there are some offering cover for cancellations due to covid-19.

Proof of travel insurance is mandatory before starting the trek. Standard policies often only cover medical evacuation to 4000m so make sure the policy you get covers trekking as an activity up to the trek max altitude. Some policies require that you pay for evacuationup front and will reimburse you when you get home and submit the documents. Evacuation can cost up to €5000 so make sure that your policy will actually pay for any expenses while you are travelling. You only need to be covered on the policy for the days you will actually be trekking.

It does not happen often but if you are evacuated and want to make an insurance claim its mandatory to get a hospital report in the country as soon you get off the mountain. Often, trekkers with altitude sickness feel better once they get to a lower elevation, but it’s important to get the proper medical documentation for claims. The hospital will charge you a fee of $150 for the medical report required by your insurance. You are responsible for any evacuation or medical bills that are incurred. Most insurance companies will cover these costs for you before you leave the country, but some will want you to pay all costs out of pocket and then reimburse you. We suggest that you check your insurance policy and ensure that they will cover all costs upfront in the event of an evacuation.

We allways encourage you to know what your insured for and check specifics before you arrive. 

Measure twice cut one.
