Plan your Aconcagua climb

Kandoo's View

Aconcagua is the highest peak in South America, which gives it membership to the “Seven Summits” club.

Aconcagua is one of the seven summits and comes in as the second highest, just under Mt Everest. At 22,835 feet, or 6,960 meters high, Aconcagua is the highest mountain in the western hemisphere and the highest trekking peak in the world.

The fact that it is a 'trekking peak' does not mean that it’s easy though.

To climb Aconcagua you need to be physically fit, have strong mental stamina and be capable of strenuous exercise for several days duration. Expedition members can expect to be exerting themselves for about six hours per day and be capable of carrying a 15-20 kg pack.

The altitude and weather combine to make this an adventure that tests even the toughest. In good conditions it is hard but not technically difficult. In bad conditions it is virtually unclimbable.

As a result of this we build plenty of rest and contingency days into the itinerary. This gives you the best chance of summiting and seeing the great views of the Andes from the top. Our highly experienced local guides have a great record of getting climbers to the summit safely.

If you have already climbed Kilimanjaro, or summited one of the trekking peaks in Nepal, then this is a great next step. However, make sure you turn up the fittest you have ever been and ready for an endurance marathon. The reward for those summiting are amazing - stunning views across the Andes!

Climb Aconcagua summit - One of the seven summits

When is the best time to climb Aconcagua?

You can climb Mt Aconcagua from November 15th to February 20th, with the peak season running from the middle of December to the end of January. While we would expect the best trekking conditions to be in the peak season, as with any mountain environment the climate can vary considerably from the norm.

There are three contingency days in our itinerary to allow for unpredictable weather and the best summit window opportunity. The chart below summarises the weather conditions by climbing season.

Off Season
Off and low season for climbing Aconcagua
the mountain can be climbed during the off-season, however it is not recommended as climbing conditions are not favourable and support services limited From 21st February- 15th November
Low Season
Off and low season for climbing Aconcagua
The low season covers a two week period in November (15th to 30th). Weather conditions during these periods are relatively stable, but you can expect colder conditions than the mid or high season. The mountain is considerably quieter. From November 15th – 30th November
Mid Season
Mid and high season for Aconcagua mountaineering
The mid season sits on the shoulder of weeks wither side of the high season. It is a good time to tackle Aconcagua as conditions are nearly as good as the high season, but the trails are still quiet, particularly in February. From December 1-14 and February 1-20
High Season
Mid and high season for Aconcagua mountaineering
The high season consistently provides the most stable weather on the mountain and hence 80% of climbers undertake their Aconcagua climb during this window. From December 15 to January 31

How hard is it to climb Aconcagua?

There is no technical climbing on the "Normal Route" up Aconcagua. You need experience walking in crampons and with the use of an ice axe but nothing more. However, the sheer height of Aconcagua, along with extremely cold temperatures on the mountain, make it a challenging ascent, even for accomplished mountaineers.

Since the summit is close to 7,000m, climbers have to spend sustained periods camping in tough conditions at high altitude - this can be mentally and physically draining. Climbers also have to help take kit to the high base camp which involves carrying more than your day pack.

Moreover, weather conditions high up on the mountain can change rapidly, with extremely cold temperatures as low as -30°C not uncommon.

Aconcagua is a big step up from Kilimanjaro. That being said, summiting Aconcagua via the Normal Route is very attainable for those with the right attitude, who have trained well and are mentally prepared for the rigours of high altitude trekking.

How much does it cost to climb Aconcagua?

In addition to the cost of your gear and the cost to travel to Aconcagua from wherever you are, you will also need to pay to actually climb the mountain. This is done through the purchase of a permit in Mendoza to enter the national park. The price can vary depending on when you choose to go, but it averages between $800 and $1000.

About Aconcagua

Aconcagua - history of Argentina's highest mountain

While there is no hard evidence of native Incas having summited the mountain, there is reason to believe they ventured far up the slopes of Aconcagua. Mummified bodies and the remains of a guanaco, a type of humpless camel, have been found as high up as 17,000 feet, with the latter lending its name to the ridge between the two peaks, now called the Cresto del Guanaco.

The first documented attempt on Aconcagua was by Paul Güssfeldt, a German mountaineer. Legend has it that he bribed some local men to be his porters by promising them that there was treasure on the mountain. He was forced to descend only 1,000 feet below the summit due to dangerously high winds.

Several years later, in 1897, a team lead by British explorer Edward Fitzgerald attempted to reach the peak by using a different route to that used by Güssfeldt. This became the Normal Route. It was only the team’s guide, a Swiss man named Mathias Zurbriggen, who reached the summit, as other team members experienced altitude sickness just below the summit.

In more recent times, Aconcagua has been the target of many aptly named ‘mountain runners’. World renowned endurance athlete Kilian Jornet completed the ascent and descent of Aconcagua in 12 hours 49 minutes in 2014, setting the record only for it to be broken two months later by a Swiss-Ecuadorean individual named Paul Egloff. He completed the round trip in 11 hours 52 minutes, which is the current record for the fastest ascent-descent.

With 3,500 people attempting the climb each year, there are sure to be more interesting facts and figures coming out of the Aconcagua area in the future. Until then, why not make your own history by climbing the magnificent Aconcagua?

Frequently asked questions


To give yourself the best shot at summiting Aconcagua we recommend being in the best physical shape that you can possibly be. This means having a strong cardiovascular system and aerobic fitness level. If you live in an area that is blessed with mountainous terrain, then the best training you can do is to take frequent hiking excursions. However, for the majority of folk who don't live near mountains, then we recommend a strict gym training regime for 3-5 months before taking on Aconcagua. Your training regime should consist of aerobic activities like running, spinning or spending time on the rowing machine. You should couple aerobic exercises with weight training to strengthen your legs and core. We recommend squats, lunges, kettle bell swings and sit ups.


To stay safe and avoid taking unnecessary risks, you should only ever climb when it is deemed safe. This is why many areas have climbing seasons designated to when conditions will be ideal and the climb poses the least risk of harm.

For Aconcagua, the climbing season runs from 15th November to 20th February, with the high season running from mid December to the end of January. This period generally offers the most stable weather on the mountain and lots of summit window opportunities. If your schedule doesn't allow for a high season climb, then we recommend looking at the shoulder weeks of the mid-season from either early December or early February.

Q3How long does it take to climb Aconcagua?

The amount of time it takes to make it to the peak of the mountain very much depends on the amount of training you have done and how physically ready you are. On average, for someone who has trained for the trek, it will take roughly 15-18 days.


Yes, unlike many operators who do not include the Aconcagua permit in their tour cost, all Kandoo Aconcagua climbs include your park permit. The fees for permits vary by season (low, mid and high season), route and by nationality (Argentinians and Latin American's get a discount). Prices for permits are released a few weeks before the climbing season and can be accessed here:


For the summit attempt, our guide-to-client ratios are 1/3 - 2/7 - 3/11. You may have fewer guides as you move up the mountain from base camp to the higher camps, but additional guides will be ready to assist with the push to the summit. We like to keep our groups relatively small to give everyone a good chance of summiting. In our experience an optimum group number is 6 climbers.

If we reach 9 climbers in a group we split the group. Our highly experienced local guides have qualifications from the High Mountain and Trekking Guides School in Mendoza (EPGAMT) an Argentinian (AAGM) Mountain Guides associations. Our staff are carefully selected and trained, and all of our guides are active year round. With such a short climbing season on Aconcagua, it is important that out guides maintain their skill levels so they will travel the world to provide high altitude guide services for the remainder of the year.

Our camps are coordinated by a Head of Camp and attended by a specialist (and assistant) chef trained to satisfy your needs. At base camp we have dining tents with electricity, tables, chairs and crockery. Rooms with beds set up in large tents. Kitchen, bathroom and a tent luggage deposit.


It is a condition of joining an Aconcagua climb that you have insurance that covers you up to 7000m and that cover extends to the full cost of evacuation if needed. Policy providers we recommend are Dog Tag and World Nomads, both of whom sell specialist climbing insurance.


We recommend bringing three types of bags for your Aconcagua expedition: a large duffle bag (80-90L), an expedition rucksack (70L-90L) and a light daypack (30-35L).

For the hike into Base Camp we use mules to carry most gear and supplies. As a climber you will only carry your daypack (water, snacks, camera, jacket, sunscreen, etc.).

From Base Camp to High Camps you can expect to carry all of your personal gear plus a share of the common gear (although we provide porters for group equipment). On average, a fully-loaded Aconcagua backpack weighs 18-22 kg.

We offer our own reliable team of porters to carry gear up and down the mountain. Each porter carries up to 20 kg from Base Camp to any given camp and down from high camp or other camps to Base Camp. On our trips we include one porter for every four climbers, to carry common gear only when the group moves from one camp to the next. Porters don't assist in the cache and carry trips (i.e. not when the group carries gear to a cache and comes back to camp). Climbers who don’t want to carry weight can hire a personal porter, on a daily basis or for the whole trip. Please contact us for personal porter rates.


Common gear, such as tents, stoves, garbage, first aid kit is carried up to Base Camp by mules.

From Base Camp up to the first High Camp we do not use mules as they cannot work at these higher altitudes. One porter for every 4 climbers will take over carrying some of the "common gear", plus the clients will also be expected to carry a share of common gear. You will need to be able to carry a load of between 18-24kg (personal gear + share of common gear) and ensure that your rucksack is large enough to accommodate the extra load you will need to carry from Base Camp up to the first High Camp.


The success rate fluctuates around 50-70% each year, with failed summits largely due to altitude related issues and poor weather conditions
