Mount Pissis - 16 days


Mount Pissis -

Next Expedition: 16 January 2025

Mount Pissis is the third highest peak in the Andes and one of the most stunning 6000 metre Andean peaks. Standing at 6793 metres above sea level, Pissis is pretty remote. Although it has an accessible drivable approach, it has a 190 kilometre offroad approach.

The volcanic complex of dormant volcanoes has an extensive glacier with large crevasses, something very unique in the dry Andes. This is due to its massive high altitude plateau that collects enormous amounts of snow even during the summer. It was named Pissis after a french geologist who worked for the Chilean government, Pedro José Amadeo Pissis.

The approach is also very unique. It features all types of wildlife like vicuña, guanaco, foxes and condors. There are 3 major lagoons on the way to Pissis and each one has its own colour ranging from very light turquoise to dark green.

Requirements to join this expedition are:

  • International Travel Insurance;
  • Altitude mountain climbing or multi-day altitude treks;
  • Be healthy and fit enough;
  • Fill the booking and medical form;
  • Read all the information available on this website.


Mount Pissis - 16 days

Day 1 – La Rioja City Airport – Fiambalá – 1200m

We will previously organise our logistics at Fiambala, then pick you up at La Rioja. Tonight the whole team will gather together and go through all expedition details. Included: breakfast, hotel in Fiambala, drive from the airport.

Day 2 – Fiambala – Cortaderas – 3300m

Time to leave civilisation. After loading all water containers and fuel pods, we start the 2 hour drive to Cortaderas. This is a massive hotel located in the middle of nowhere! On the way we will drive though beautiful valleys and landscapes. Included: breakfast, night in hotel, 4wd drive, lunch break and dinner.

Day 3 – Cortaderas – Las Losas – 3700m

In order not to push acclimatisation, our guides will take you for a night at 3700 metres. Although this a very welcome stop, we’ll have to spend the night in a fairly small hut which was built on the side of the road to offer shelter in case of emergencies. This will be our kitchen, living room and if all agree, our bedroom for 1 night. We also have the option of camping outside in a 5 million star hotel. Included: Breakfast, Lunch, Dinner, night in a mountain hut and the drive.

Day 4 – Las Losas – Falso Morocho – Las Grutas – 4100m

Falso Morocho is a 4500 metre peak not far from the road. We will drive to the base of it and you’ll have to walk the rest of the way. This acclimatisation walk might take us 3 to 4 hours including a lunch break. We will then drive to Las Grutas, where the Argentine customs control is located. We however don’t have to control our passports as we won’t leave Argentina. Included: Breakfast, Lunch, Dinner, night in a hut (bunker beds) and the drive.

Day 5 – Las Grutas – San Francisco Pass – 4740m

After a half hour drive from Grutas on a paved road, we arrive to San Franciso pass which is the border between Argentina and Chile. After a lunch break at 47000 metres, we’ll take an acclimatisation walk so acclimatisation settles in properly. Included: Breakfast, Lunch, Dinner, night in a mountain hut and the drive.

Day 6 – San Francisco Pass – Laguna Aparejos – 4190m

After a 120km drive on paved roads and 38km offroad drive, we’re at Laguna Aparejos, an amazing light coloured lagoon located 40km away from Pissis. Included: Breakfast, Lunch, Dinner, night in tents and the drive.

Day 7 – Laguna Aparejos – Pissis BC – 4600m

This is when the fun starts! We’ll have to overcome some difficult mountain passes in our 4WDs but we get to see some amazing lakes on the way. They’re all salty lakes but if we’re lucky we might see flaminco colonies. Basecamp is located at the end of a flat valley, 8km away from Pissis. Included: Breakfast, Lunch, Dinner, night in tents and the drive.

Day 8 – Carry to Camp 1 – 4600m

It would be too pushy to just keep going higher due to acclimatisation. So we use this trip to carry half of our loads to camp 1 located at 5360m and drop back to BC. Included: Breakfast, Lunch, Dinner, night in tents.

Day 9 – Pissis BC – Camp 1 – 5360m

We take the rest of our loads to Camp 1 today. A tiny path which often fades out, takes us through valleys and side moraines to a snowfield. Camp 1 is located at the top of a massive plateau. Views from here are stunning already. Included: Breakfast, Lunch, Dinner, night in tents.

Day 10 – Rest at Camp 1 – 5360m

Priority today is to rest. If everyone is ok, we can go to a nearby glacier to train our cramponing. Included: Breakfast, Lunch, Dinner, night in tents.

Day 11 – Camp 1 – Camp 2 – 5900m

Not long after leaving camp 3 we hit a glacier. Depending on the ice conditions we might have to crampon up all the way to camp 2. It is located on a huge step, very close to Pissis. Included: Breakfast, Lunch, Dinner, night in tents.

Day 12 – Summit of Pissis – 6793m

Early start! The push to the summit might take us up to 8 hours one way and 2 or 3 return. Most of the way is over a glacier with a very gentle slope. From 6400 metres onwards, we might get wind gusts from west as this is normal in the region. Included: Breakfast, Dinner, night in tents.

Day 13 – Camp 2 – BC – Cortaderas – 3300m

Yes, it is a long day… But very exciting though! The descent from camp 2 to BC is very straight forward. After a lunch break at Camp 1 or BC, we’ll start our 4WDs and drive 105km to Cortaderas. The drive alone might take 5 hours. Included: Breakfast, Lunch, Dinner, night in tents and the drive.

Day 14 – Spare day in case of bad weather – (Or argentine BBQ at Fiambala!)

Day 15 – Cortaderas – Fiambala – La Rioja

We’ll drive you for 5 hours all the way to La Rioja Airport. Included: Breakfast, Lunch, night in hotel and the drive.

Can I hire a porter?

Unfortunately, it is a very remote mountain and there are no permanently installed services there.

I can exchange money in La Rioja?

Yes. There are exchange offices that buy US dollars, sterling and euro in La Rioja but not in Fiambala.

There is communication on the mountain?

Yes! At any time you can use our satellite phone. The calls cost U$3/minute. Throughout the expedition, we will post daily updates to our Facebook page via SPOT satellite.

Would you guys call my family and tell them I’m alright?

Of course! Even better! We have a blog that is updated every day! We normally post messages or photos about the expedition progress. Please visit our Facebook page and check the latest posts.

I’ve heard Pissis is just a walk, is it true?

In fact, Pissis is not a technical mountain. Don’t forget the mountain is almost 7000 meters high. Altitude and bad weather have caused many people to lose their lives because they didn’t respect their own boundaries and underestimated the mountain.

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 La Rioja or Fiambala, 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.

If you quit the expedition after we left Fiambala, you will have to cover individual transportation and accommodation costs. Everyone who leaves the expedition for personal or health reasons should pay these costs.

If you give up 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.

To leave Pissis, one of our vehicles will have to travel 400km to make a roundtrip to Fiambala. Fuel, maintenance and guide’s expenditure must be covered in case you wish to return home.

What’s your philosophy?

We accept women and men of any age, experience or ambition. We ask our members to be patient, respect the leader’s decisions and never go up or down alone.

Remember that you don’t pay us to take you to the summit, you pay mountaineering professionals with several years experience to help you up and down a steep mountain in the safest possible way.

Our itinerary may seem slower than other companies, this is due to a longer acclimatisation plan based on safety. More days will actually improve the chance of reaching the summit!

Can pay for rental equipment with a credit card?

No, this must be paid in US dollars to our guides.

How much does the climbing permit costs?

There is a required permission to climb Pissis. This has no cost and is carried by the expedition leader.

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 Pissis?

Ideally, anyone attempting Pissis should have climbed a 6000 metre peak before, in order to become familiarised 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.

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 mmacrobiotic vegan or celiac due to extreme logistical difficulties. Contact us and let us know about your food restriction.

Who cooks at the altitude camps?

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

What if I have a health problem?

Our leaders have extensive experience in mountain medicine and can solve most of problems you might encounter.

What if I need a rescue?

All our guides are trained rescuers and experienced in rescues on big mountains. Rescues can be made with one of our 4WD vehicles, this way you can get to a hospital in five hours.

Do you recommend the use of Diamox?

NOT for the Central Andes. In extreme altitudes like the Himalayas or Karakorum we do recommend using Acetilzolamide 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.

I was climbing in Peru before and I had a hard time communicating to my guide. Do your guides speak any english?

Yes, our leader Andy Jones speaks great english. Please check our team’s information and find out about our guides’ communication skills.

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 sleeping bags. We’re focusing on the “comfort temperature”.

Andy Jones

High Altitude Mountain Guide

Language skills:

Spanish -  native speaker
English - excellent command

Nearly everyone who went to Aconcagua has heard of Andy Jones. He's one of the most accomplished guides in the region and has summited Aconcagua 44 times! Andy was born in Rosario, Argentina's capital of the pampas (flatlands). During his early career, he worked as a physical educator (a job he's still very proud to keep), but eventually moved to Mendoza and lives there for the last 26 years. Andy Jones has climbed every sort of Andean mountain since he started climbing in the early 90s. He also climbed several high peaks including the highest in Peru, Bolivia, Chile, and Argentina. The well-known Andy Jones is an extremely relaxed and easy going person. All this patience probably led him to conquer the reputation of being one of the most successful guides in Argentina with one of the highest summit ratios in the country. Andy is definitely the guy who you want to have around if just started climbing high mountains.
