Climb Aconcagua (6,962 meters/22,841 feet) the highest peak in the South American Andes, and the highest peak outside of Asia. Aconcagua is in the Mendoza region of Argentina and is one of the seven summits.

Although an incredibly high mountain in comparison to Alpine peaks, it is a feasible objective if you have a good level of fitness and previous alpine climbing experience on peaks such as Mont Blanc, Elbrus and Kilimanjaro. The main challenges faced on Aconcagua are dealing with the high altitude.

Who is this for?

Anyone with a good level of endurance fitness and a sense of adventure can qualify for this trip providing you have previous experience climbing Mont Blanc, Elbrus or Kilimanjaro or trekking / climbing to altitude heights at 4000 – 5000m. Some previous mountaineering experience is essential even though this climb is not technical. You must have previous experience dealing with altitude, Elbrus and Kilimanjaro are particularly good for preparation in dealing with altitude.

Aconcagua is the highest peak outside of Asia and determination is needed to keep going to the top. Making sure you have a good base fitness level before you arrive will make the climb feel less strenuous and maximise your chances of success.

Accommodation and huts

Two nights in nice comfortable Mendoza hotels on a twin room shared basis with others on the same trip. One night in a mountain ski lodge. Five days in tents at base camp and eleven days in double occupancy tents on the mountain.
Breakfast only included on hotel nights and all meals included on trek. Wine, beer, and bottled drinks available at additional expense. Mountain food will be a mixture of cooked dishes and prepared dry bag mixes.

What to expect from the climb

Aconcagua is an ideal test piece before a Himalayan spring expedition and a fine tune-up before an 8000m peak. This is a challenging mountaineering expediton. Summit day will take you to the limit of your endurance.

You will be carrying your own personal equipment or hiring a porter to assit when you go up the mountain to sleep above base camp. On summit day your pack will be lighter carrying your essential kit for warmth and safety as well as food and hydration. Summit day will be on average 12 hours with a pre-dawn start.

To maximise your chance of summiting Aconcagua it is important to get as fit as you possibly can. So we have partnered with Uphill Athlete, specialists in strength and conditioning for peak mountain performance to offer you a variety of different training plans via their website.

Read an Introduction to Uphill Athlete by Steve House, accomplished climber and IFMGA guide here

Mountaineering is all about being able to exercise at a moderate intensity for many hours (typically 5 to 12 hours) and your training should reflect this. Balance is important too as you will spend many hours walking in crampons. For this a good chore strength is important.

Remember to build up your workouts over time. If you are not used to exercising much, your muscles and joints need time to build up to avoid injury.

We highly recommend contacting Uphill Athlete to find a training plan that will help to get you in shape for this trip.

The Effects of Altitude

As you climb higher the air gets thinner and so there is less oxygen in each breath you take. This makes exercising much more strenuous than at sea level and so you have to slow down to help compensate. Because you have slowed down, you may also feel colder.

Because there is less oxygen in the air as you get higher, this can lead to ‘altitude sickness’ or Acute Mountain Sickness which will feel like the worst hangover you have ever had (headache, nausea, weakness, fatigue, dizziness) and can develop into a very serious and even fatal (in extreme cases) problem.

To avoid these problems and enjoy the climbing and increase our chances of reaching the summit, we need to acclimatise by spending several days and nights at progressively higher altitudes, so our bodies can adapt. This is a very important part of our preparation and is factored in to our itinerary.

Top-Tip:​ It is a dusty trek in to Aconcagua. You’ll be amazed what the famed ​viento blanco​ winds kick up trekking into base camp. Some consider this trail day the second hardest apart from the summit. Top-tip, pack a Camelback water bladder to minimize stops and stay hydrated. Pack your buffs, your goggles, and ideally even a sun hat with ear and neck protection.

Please note this is a guide and you may be required to rent or purchase last minute equipment on arrival dependent on the weather and changes in itinerary.
