Mercedario - 15 days


Mercedario - January 2021


At 6770 metres high, Mercedario is the 8th highest mountain in the Andes and is located in the San Juan Province, Argentina. This is a great option for those who want to try a very high mountain but want to avoid the crowds of busy mountains like Aconcagua. Furthermore, Mercedario does not require a permit like Aconcagua, making it significantly cheaper. The normal route is extremely accessible and requires no technical climbing.

During the peak season at Mercedario (December to February) we won’t find more than 5 expeditions at once trying the summit. Meanwhile, in Aconcagua there might be at least 80 expeditions trying the summit at once.

The requirements for joining this expedition are:

  • International Travel Insurance
  • Multi-day altitude trekking experience
  • Good health and physical prepared
  • Fill the booking and medical form
  • Read all the information available on this website
  • The expedition has to reach the minimum of 4 participants (ask us how the bookings are).

How much equipment will I have to carry? Can I make it?

Your backpack will never weigh more than 12-15 kg. We prepared our itinerary in a way so your equipment is split into 2 loads to be taken up in 2 different days. This way you don’t have to carry so much weight.

Do I have to carry tents and stoves?

No, the guides will take care of carrying and assembling all equipment, camps and cookware.

Are there any mules to carry my equipment?

Yes. Up to 5200m (Pirca de Indio camp), we will take mules. Until then you’ll only carry a small rucksack with water and basic trekking equipment. If there is an excess of snow, the mules might not get all the way to Pirca de Indio and they might get up to Cuesta Blanca at 4400m. In that case, we’ll use one of the extra days to take half of our equipment and break the total of weight in half.

Is there 4G at Mercedario? Do you have a sat phone?

No, there isn’t 4G connection of WiFi on Mercedario. We will however take a satphone for logistics and emergency call. If you wish to make personal calls, there is a cost of USD 3/minute.

Do I have to share tents with anyone?

Yes. All tents are shared by every 2 persons and this is previously agreed.

I heard Mercedario is an easy trek, is that true?

In fact, anyone can get to the summit of Mercedario without climbing anything technical. There are no technical steps on the normal route of Mercedario. We are however talking about a nearly 7000-metre peak and anything can happen. Several unprepared climbers lost their lives due to relatively simple mistakes. Please read all information before attempting any high altitude mountain.

Can I charge my iPhone battery or my camera?

Yes! At the base of the mountain, we have solar panels to charge batteries, iPods, etc. Of course, this changes when there’s no enough sunlight.

What if I abandon or quit the expedition?

If you quit the expedition 1 week before departure, it is possible to recover part of your investment. Contact us and find out more.

If you quit the expedition in Mendoza, you can continue enjoying the services we provide you such as transportation and hotel. However, we can not pay back the money you invested because logistics will already be hired. Everyone who leaves the expedition for personal or health reasons should pay these costs.

If you quit during the summit attempt, you will never have to go down alone. Usually, we coordinate your descent with more expedition members. One of the guides will always be with you.

For example, if you decide to abandon the expedition at Hoyada at 5650m high, you might have a 250~450 cost to get to Mendoza.

How much money should I take?

There is nothing to buy at Mercedario, but you might want to purchase something on the road or in Barreal. Once we leave Barreal, all expenses are on us. You need money to rent equipment and pay for food in Mendoza. We recommend you to have about U$900 in US currency. This is a rough estimate:

Dinner and lunch in Mendoza (average of general expenditure): U$150
Equipment rental: U$450 (average)
Cost of abandoning trip: U$300 (average. You should take this just in case)

Can I use credit cards in Argentina?

We do not recommend you using credit cards in Argentina. In addition to the up to 25% tax, it is quite possible that your credit card might not work due to the poor communication system. Only major hotels and supermarkets might accept foreign credit cards. The financial situation in Argentina is very unstable so we highly recommend you to bring US dollars.

How much is the permit to climb Mercedario?

Zero! No permission is needed to climb Mercedario.

What sort of training do I need for big mountains like this one?

To 6000m mountains, we recommend you start training at least three months before, depending on your physical condition. Aerobic exercises like running and cycling are very useful. Ideally, ask a professional to recommend you a good aerobic training program. A very effective exercise is to go hiking with a rucksack on lower mountains. BEWARE of injuries! We have had some cases of clients who have trained too much and ended up hurting themselves.

What experience do I need for Mercedario?

Ideally, anyone attempting Mercedario should have climbed a 6000-metre peak before, in order to become familiarized with acclimatisation and snow walking. We, however, understand how hard it can be to have enough holidays in a year to climb these. So alternatively you can get away with just a multi-day altitude trek such as Everest Basecamp, Annapurna Basecamp or Machu Picchu. If you don’t have high altitude experience and you do have have to acquire experience before Mercedario, please let us know and we can organise an expedition for you.

How is the weather in Mercedario?

Even though we normally climb Mercedario in summer, remember this is one of the largest mountains in the continent and we can easily get freezing temperatures even during the day. The atmosphere between Mercedario and the end of the stratosphere is so thin that climate is not regulated as sea level. Temperature variability becomes extreme. We can have very warm days and freezing cold soon after that. To make it worst, strong high altitude wind is added so everything changes even more. In another word, expect anything but prepare for the worst! An average day is normally 10ºC temperatures drop below zero overnight. Occasionally we have storms. It is common to have at least one snowstorm during the expedition.

What if I have a special diet?

Please tell us in advance about any food issues you might have and also please remind our guides about it too. Unless you bring your own food, we cannot help you if you are macrobiotic, vegan or celiac due to extreme logistical difficulties. Contact us and let us know about your food restriction.

Who cooks at altitude camps?

We have very skilful guide/cooks. We guarantee you will e impressed about the meals!

Is there water during the approach?

Yes, there are plenty clean water streams during the approach. The presence of cows however, requires you to treat the water with chlorine tablets or anything similar.

What if I have a health problem?

All our guides have extensive experience in mountain medicine and can solve most of the problems you might encounter.

What if I need a rescue?

Helicopter rescues can be made by helicopters at a few specific points in this mountain. They are a VERY complex but can be done by a company who normally performs helicopter rescues at the neighbour Aconcagua. These however are extremely expensive and it is vital that you have a rescue insurance.

Do you recommend the use of Diamox?

NOT for the Central Andes. In extreme altitudes like the Himalayas or Karakorum we do recommend using Acetazolamide or Diamox. This drug seems to actually work during the acclimatisation period by increasing the breathing rate at night (reduces CO2 levels), and also is a diuretic which eliminates sodium out of your system. In the Andes mountains, however, mountains are too dry and taking diuretics such as Diamox actually decrease your acclimatisation capacity.

Do your guides speak any English?

Yes ALL our guides speak fluent english. Please check our team’s information and find out about our guides’ communication skills.

What percentage of your clients actually make it to the summit?

It depends upon weather, experiences, fitness and their nationality. But usually, about 90% of our clients get to the top of Mercedario. We believe such a success rate is due to the experience of our clients. People who want to climb Mercedario are usually more experienced than Aconcagua clients.

Where do we go to the toilet on the mountain?

There are no toilets at Mercedario. In each camp we set up a toilet tent and do our ‘business’ in bin bags. All these bags are later brought down. Everything will be transported to Mendoza on the way down. We leave no trash on the mountains.

What if I want to rent equipment?

It is very easy to rent equipment in Mendoza. Check out the list of equipment (under the equipment tab) needed before buying anything. Rentals can be paid in dollars or pesos but NOT with credit cards.

What’s the temperature my sleeping bag should stand?

We recommend you to bring good down sleeping bags with comfort temperature of -15 up to -22. Please note there are 2 types of temperatures shown in most of the sleeping bags. We’re focusing on the “comfort temperature”.

Do I need an entry visa to go to Argentina?

Depending on which country you come from. Canadian and Australian citizens, for example, have to pay a U$160 visa to enter Argentina as per reciprocity fee. This should be paid at the airport in cash.
