Altitude 6962m, Grade 1C

Named ‘Acconcahuac’ (the stone sentinel) by the Incas, Aconcagua is the highest peak in the Southern and Western hemispheres, the second highest of the Seven Summits and the world’s highest summit outside of the Himalaya.

Our route of ascent for Jan & Feb 2022 will be via the normal Horcones valley (The Vacas valley routes remain closed for this season). We have included an ascent of Bonete Peak (5,004m) to help you acclimatise and there are four possible summits days providing you with the best possible chance of summit success.

The Horcones valley route on Aconcagua offers the strong mountain walker, with prior winter walking experience the opportunity to ascend one of the world’s highest trekking summits. Although you will not require any previous climbing experience, the ascent is at very high altitude and therefore requires a high level of fitness, commitment and determination.

The climb is very weather dependent but our high guiding ratios, small group size and levels of support generally gives us a big advantage and improves our summit success. We provide leaders/guides on a maximum ratio 1:3 above Base camp  allowing time for you and your guide to get to know each other and the team is limited 9 climbers. Our aim is to reduce the physical hardship and create maximum flexibility to give you the best chance of summit success as we can more easily deal with clients varying walking speeds/fitness and weather. Porters carry any group gear (tents, stoves, shovels, fuel) and we will work with you in the months preceding your expedition to help you identify the very lightest kit possible to further reduce your load to around 14kg plus water. Your guide will assist you with tent placement, cooking and water preparation. The expedition will still be physically challenging (all 7000m peaks are!) and you will still have to work hard to reach the summit but you will probably have the best guiding ratio on the mountain throughout the expedition.

Why climb Aconcagua with Adventure Peaks

  • £600 of permit fees included in the price (often exluded by many operators)
  • Up to 4 days set aside for a summit attempt
  • High-altitude porters to carry group equipment (tents, stoves, shovels and fuel)
  • Expedition leaders from the UK who are supported by our regular team of local Argentinian mountain guides to give a 1:3 ratio throughout your climb above base camp. Many operators only increase their ratio to this level on summit day allowing little or no time to bond or get to know you! Maximum 9 clients
  • Quality food – our guides prepare or assist with all meals at Camps above BC using a variety of ingredients, to avoid the use of freeze dried food until higher up the mountain
  • Adventure Peaks has been operating successfully on Aconcagua for over twenty years and we have gradually developed what we see as the best overall approach the mountain, giving you the best chance to acclimatise and retain strength for your summit bid
  • 100% trip success in the 2019/20 season (prior to Covid)

Or choose the Highly Guided upgrade

You can choose to upgrade to your own personal local guide on summit day (standard ratio 1:3), allowing you to move at your own speed, and giving you the very best chance of summiting.

Previous experience/fitness

The climb up Aconcagua is non-technical. It is suitable for mountain walkers with previous winter walking experience. The route may be dry or may have a solid covering of snow and ice. Clients should have prior experience climbing to around 6000m before attempting Aconcagua. Previous experience of camping, as well as carrying loads of 14kg, would be advantageous even though porters carry all group equipment.

Summit day is long and tiring, ascending(from 5950m at high camp to the 6962m summit. This could take 8-10 hours to ascend and 2-3 hours to descend. You should make sure you are fit and used to long mountain days.

The route

On our approach in Jan-Feb 2022 will be via the normal Horcones route as the Vacas Valley remains closed. Mules are used to support the trek into base camp. Our itinerary provides upto 4 summit day giving you the best chance of success. One of the ‘Seven Summits’.

Weather conditions

It can be very hot in Mendoza and on the walk in to basecamp. Wearing shorts and t-shirts with sunhats and plenty of suncream is the norm, however there can also be torrential rain on the walk in so full waterproofs are also essential. From basecamp upwards there can be heavy snowfall, and from Camp 1 up the wind can cause severe wind chill. At high camp and on summit day the temperature can drop to -20 Celsius, so down jackets, good mitts and double boots are essential.


No visa is required for UK and US Citizens and many other countries. For non-UK citizens, you may need to pay a Reciprocity fee before you enter Argentina.
Aconcagua climbing permits are included in our expedition price but we must all go to the park office in Mendoza to register and pick them up.

  1. Rated 5 out of 5


    Aconcagua is no trekking peak and overall my best trip yet, absolutely fulfilling my expectations. It was tough than people thought and the leaders were top class turning a large group in to a large team. They were not just great leaders but great friends. 10 out of 10. Also the local guides were spot on. I chose AP because of the people involved from the shop to the mountain!.
    Thank you very much, an exceptional expedition from start to finish. Can’t wait for the next one, Cheers.

    Over all the trip was well run and both Mark and Kieran worked hard to ensure things went well for everyone. One of the best organised on the mountain, thanks to Mark and Kieran

    Karen S

    I had a good timely response to my initial enquiry with the number of summit days and the route appealed to me. Appeared professional and inclusive.

    I really like the Adventure Peaks settup including shop, hire, weekends and the personal touch from Dave. Kieran worked extremely hard to sort the camping food and he did an excellent job. It was plentiful, varied and easy to manage.

    The local support team were excellent with superb safety on summit day.

    Cathy S

    Overall, the trip was brilliant and very enjoyable. Mark and Kieran are superb leaders, mature and confident always putting clients first. I cannot fault them. Mark was also superb with the airlines. He led us on the mountain and also through our interesting time at the airport. I would use Adventure Peaks again with excellent organisation and superb leaders!

    Tents were new, excellent condition and the whole team was excellent! Great expertise/knowledge. The UK Guides were very organised and took time to teach me new skills etc. Both were brilliant.

    The only thing that I would have liked was an extra camp site at camp 3 which would have improved my summit chance. That said, i understand the limitations of being in a large group.

  6. Rated 4 out of 5


    I am impressed by your pre-support and commitment to the customer. Thanks.
    The food was very good but more pasta at altitude was a general feeling! Service and advice before booking was very helpful and afterwards it was excellent and you give appropriate advice as I was contacting you by email and got a rapid response.

  7. Rated 5 out of 5


    I had a one to one discussion when visiting your Ambleside Shop, with personal recommendations I chose Adventure Peaks so felt confident in your organisation.

    It was a very memorable trip/experience. Well organised and good attention to detail.

  8. Rated 4 out of 5


    Past experience with Adventure Peaks is well organised and has good client safety measures so I would use you again due to your track record.

  9. Rated 4 out of 5


    Service and advice after booking plus the accuracy of your brochure was great. The kit list was a great help. No real improvements in overall grade but need to consider route options. We discussed the route options with the leader. Ultimately we decided on which was probably easier with a higher chance of success than the brochure description. I would recommend making this option more visible so that the right route can be chosen to suit the clients on the day.

  10. Rated 4 out of 5


    I got to 6600m but it was very professional trip with very good guides so would use you again.

  11. Rated 5 out of 5


    Perhaps a need for more emphasis on the physical and mental toughness needed to summit Aconcagua but still all excellent.
    Kiaran was an excellent leader – approachable, supportive and very well organised. An excellent trip – tough but very rewarding.

  12. Rated 5 out of 5


    Your Argentinian guide is excellent but his English will need to improve. Having someone to speak with local staff in Spanish was very useful and beneficial. I chose Adventure Peaks because of your advice and recommendations regarding Martin our leader.

  13. Rated 5 out of 5


    The kit list could be broken down more to essential or optional, nice to have items.
    Martin was excellent and so is Maxi. You guys were cheaper than jagged Globe which is why I chose Adventure Peaks. I would definitely use you again. I am looking forward to the next trip!

    Adventure Peaks are a very professional outfit, and at a very competitive price.

  15. Rated 5 out of 5


    We had very good guides. The lead guide Martin was absolutely lovely and very patient. The local guides Pablo and Marcos were very knowledgeable. Marco’s local expertise was invaluable in modifying our schedule to use a shot at the summit.

    On summit day he set a good pace and made some tough but fair decisions regarding the progress of certain team members, for their own safety.

    Mark M

    Well planned, successful trip. Chris was very ill for a number of days during the trip but never let it affect the team. He’s extremely professional, knowledgeable and great fun to be around. We developed as a team under his leadership and were ultimately successful because of his planning and guidance.

  17. Rated 4 out of 5


    Really great trip. We summited and made it safely down so cannot complain. Chris [trip leader]…an absolute trooper given he came down with a virus, but still managed to get us to the summit and down again safely. Really thorough when it came to briefings. Really good…It took a lot of time and effort to get up there, but the views were breathtaking.

    The leader was excellent…Paul was exceptional, highly knowledgeable, very calm and controlled under pressure, excellent risk assessment and above all a highly positive attitude and encouraging nature. I cannot recommend him highly enough for future trips.

    Scott P

    Carrie [trip leader] has been the best leader I have to my previous five expeditions. Very nice, easy to talk to and knowledgeable…I dressed as Santa on Christmas Day and everyone on the mountain (including other groups) seemed to love it and bring a smile to everyone’s face.

  20. Rated 4 out of 5


    Brilliant organisation, planning, and leadership on the expedition. It’s a challenging environment and I think the leaders on the ground and support team did a fantastic job and gave everyone the opportunity to safely attempt the summit. I thought Carrie [leader] did such a great job on the mountain. Kept the team together and well managed while being approachable and friendly. She was fantastic!

  21. Rated 5 out of 5


    Excellent organisation, excellent guide/leader and thoroughly enjoyable expedition

  22. Rated 4 out of 5


    Enjoyed better retrospectively – it’s a fantastic well organised trip. Getting to the top was very emotional. The culmination of a 25 year dream and to do it with my son was amazing. You have to work really hard on summit day. Even though the trek is a difficult walk the level of hardship is high which makes it all the more rewarding. Brilliant organisation by Adventure Peaks. Trip leader was excellent, got the balance right allowing freedom whilst remaining safe.

  23. Rated 5 out of 5


    Excellent service, communication and guidance. Everything was great, especially with me booking at such a late date. Excellent leader put information across very well, very approachable with a great sense of humour.

    I’ve had two trips with AP that have both been excellent. Phil, our leader, was tip top. This was my first true expedition and one I won’t forget.

    Excellent guides and more natural experience. Trip leader was exceptional. Mountains, fresh air, Argentinian wine and food…

  28. Rated 4 out of 5


    My overall experience was fantastic, the Vacas Valley was beautiful, quiet and we were lucky to have a really lovely (if a bit mad) group which really made the expedition! I’m really glad we carried the majority of our own kit, food and equipment (even if that included our own poo…), it felt like we did it the right way and the multiple days without wifi were liberating! I think this may be the start of a new sporting obsession …

  29. Rated 3 out of 5


    Aconcagua is a marathon not a sprint. Overcoming the altitude, the constant freezing winds, the curious toilet situation, and the load carrying, is worth it for the incredible views, the team spirit and cameraderie, the stars at night and the sense of achievement.

  30. Rated 4 out of 5


    Well organised, good guide. I could nit-pick but it was all pretty good. Great group of people. Lots of fun, all topped off by the fact that I summited.
