At 6,959m, Mount Aconcagua in Argentina is the highest mountain in the Americas and is a continental high point for those undertaking the Seven Summits challenge. The mountain, located 180km west of the city of Mendoza, is part of the Andes Mountains range and is located in Aconcagua Provincial Park, one of the most spectacular protected areas of Argentina. Aconcagua is technically an easy mountain to climb if approached from the north via the Normal Route. It is arguably the highest non-technical mountain in the world when climbed via this route, although the effects of altitude, coupled with the cold weather, are just as dangerous as that found on similar heights in other mountain ranges.

The Polish Route blends high altitude with technical climbing and is often the choice of experienced climbers who prefer to avoid the crowds on the Normal Route. Two routes can be taken here - the Polish Traverse Route or the Direct Polish Glacier Route. The Polish Traverse Route does not require rope skills as the way crosses the base of the glacier. Ice axe and crampons might be needed in parts. Which route is most suitable for a climber depends on their experience, taking into account the technical level and risks involved. Both routes start at Plaza Argentina following on to Camp 1 and Camp 2.

We do a variation of the Polish Glacier called the False Polish Glacier, where we leave the route before the technical climbing starts. We cross the Vacas Valley and, after three days, we arrive at Plaza Argentina. After a period of acclimatisation, we continue to Camp 1 and Camp 2. From here, we traverse the Northwest Face. At the Berlín level, we join the Normal Route and continue to Filo del Guanaco en route to the summit.

This trek is suitable for those moving on from high-altitude trekking peaks to big mountains over 6,000m and can be achieved by an experienced intermediate. A good level of fitness and experience on mountains is recommended before departure. We put a strong emphasis on proper acclimatisation throughout the expedition. In the early days, we encourage a slow pace in order to enhance your chance of reaching the summit. Our expert logistical support and experienced guides all help to increase your chances of a successful summit on Aconcagua.

Here, we will begin the approach. Approximately four hours later, we arrive at Pampa de Lenas (Trekking Camp 1, 2,950m). We get our permits stamped at the ranger’s checkpoint and begin the approach to Base Camp. After a four-hour hike along Río de Las Vacas we arrive at our first camp, Pampa de Lenas, where we enjoy an authentic gaucho barbeque. For the entire four-hour hike into Base Camp, you will be carrying only a day pack with some essentials as the mules take care of the heavy equipment.

Day 6: Trek from Pampa de Lenas to Casa de Piedra (Camp 2, 3,240m)

Climbing Mount Aconcagua is, among other things, a significant personal and team achievement and should to be enjoyed as much as possible. To do it, it is necessary to bear in mind some recommendations when starting to prepare for your ascent. Your experience will depend on your training. The chances of success and safety margin are highly improved by proper preparation and acclimatisation to have the necessary strength to avoid exhaustion during your journey, to avoid accidents and to decrease the likelihood of mountain sickness.

We recommend that you undertake our Expedition Weekend to refresh your camp craft, check your gear, clothing, use of crampons and ice axes. Ideally, we recommend that you undertake our Alpine Skills Course to increase your understanding of what is required on this expedition. Previous experience at high altitude is a plus. Many people move up to Aconcagua from Mount Elbrus or a similar climb. That is the recommended progression to allow a higher success rate.

Our pre-expedition meetings are part of the preparation process. All team members are invited to partake and it is a good idea to attend sessions once you have made up your mind to take on an expedition. The meetings include a thorough briefing on all aspects of the trip and provide an ideal opportunity to clear up any final questions you may have.

You will need a valid full passport. Please ensure it has six months before expiry prior your departure date. Before applying for your visa, please check dates on your passport. Please bring four passport photos for visas. Visa is acquired upon entry to the country.

It is advisable to bring some money in cash for the trip. ATMs are not always reliable or might have a low daily withdrawal limit. The climbing permit is paid only with cash. There may be occasional personal expenses in Mendoza where cash is needed. Once on the mountain, US Dollars in cash are the best way to pay for services including porters, beer, tips for the muleteers, etc.


The ideal combination for an Aconcagua expedition is a large, robust duffle bag, an expedition backpack (70-90 litres) and a light, small daypack (20-30 litres).
