Playing a bit on iceOn the east face

A vantage point or a mountain?
Few would call a 5434m high mountain a vantage point, but if it’s the closest neighbour and shoulder of South America’s highest peak it can be debatable. Manso may not be the most spectacular mountain in Los Andes, but it is probably the second most climbed summit in the Aconcagua region.
During my days in Plaza de Mulas I heard guides say:
You see that yellow triangle shaped peak up there? That’s Cerro Manso and we’re going to climb it as a step in the acclimatization process.
As the peak is at almost the same height as Nido de Condores camp-spot on the normal route on Aconcagua, Manso is a perfect target for getting used to the altitude of Nido before sleeping there for the first time.

When on the summit of Manso the views are fantastic in all directions. In the north you have an ocean of peaks in front of you; La Mano and the far away Mercedario are the most impressive. To the north-west you have excellent views of the nearby Cuerno. South-west is offering you Catedral and Bonete and of course the Aconcagua’s south-east approaches are what really catch your interest when you sit down watching the scenery from the little cairn on the summit of Manso. The mountain can also serve as a vantage point if you are heading for Cuerno. It’s a perfect place to study your alternatives on the ridge or the glaciers in the north. The little east face offers a short but nice ice climb, with steepness up to almost vertical sections. An approach from the north involves glaciers, but no steep climbing.

Getting There

MoonlightMoon over Manso

The Aconcagua page on this site is an excellent source of information on this matter, but here is a brief on how to get to Cerro Manso.
There are two main entry points to the area: Santiago de Chile and Mendoza. Regardless of which of these you choose, you have to go to Mendoza and apply for a permit for Aconcagua National Park where Manso is situated. A majority of visitors are joining commercial expeditions and if that is your choice, all the travel to the peak will be taken care of.
If you want to take care of the travel arrangements by yourself, here are some alternatives.

Go to the main bus station in Mendoza and buy a ticket to:
1). Potrerillos – for acclimatizing in the Cordon del Plata area.
2). Uspallata – if you want to break up the journey in two parts and do some popular horse riding in Uspallata.
3). Puente del Inca – from where you start walking towards the peak. A more uncommon alternative is to take the bus to Penitentes, from where you access the path to Plaza Argentina, which is the base camp on the east side of the peak. Puente del Inca and Penitentes are both located close to the gates of the national park where you check in and take care of the red tape.

The normal way to get to Manso is as follows.
Walk from Puente del Inca to Horcones, the park gate. This stretch is 4 km and is on very broad walking paths. An easy walk in a sometimes quite narrow canyon takes you to Confluencia. Walking times varies a lot, but count on anything from two to five hours, depending on how much you carry and how well acclimatized you’re. Confluencia is a good place to spend the night and you have to register at the ranger’s hut here. The next step of the walk is to Plaza de Mulas, which is a five to ten hours walk away. Down into a river valley to start with. Be sure you walk to the left when you see the river, otherwise you may end up in Plaza Francia, the base camp at Aconcagua’s south face. After the steep uphill at the river, you’ll walk in a wide valley for a couple of hours. Water is accessible most of the way, but it’s smart to fill up when you have the chance. The last part up to Plaza de Mulas is steeper and you better watch out for arrogant mulateros on their mulas the sometimes narrow paths. Check in at the gate and find yourself a camp spot. Looking up at Aconcagua’s western slopes, you will also see a yellow little pyramid on the left – Manso.


When entering the national park you have to camp in the official camp grounds.
These are: Confluencia, Plaza de Mulas, Plaza Argentina and Plaza Francia. When above these places you can camp anywhere you like. There are huts in some places, which are free of charge. The most commonly used are the two huts in Camp Berlin. Close to Plaza de Mulas there is also a hotel and some seasonally permanent tents you can rent a place in.
In Plaza de Mulas you have to ask where to pitch the tent. Some of the places are claimed by commercial companies.

Mountain Conditions

The view from very close to...The view from the summit

There are websites monitoring the weather for the area, but as Manso isn’t a peak you reach in a day, they can only give you a general idea about temperatures etc. Much better is to talk to the rangers and expedition organizers in Plaza de Mulas. They all have fresh information from various sources and usually also lots of experience about weather patterns in the area. When anyone points out there is a Viento Blanco (White Wind) coming up, be attentive. These are the infamous storms that plague the Andes. A certain sign a Viento Blanco is approaching is a veil-like cloud over the summit of Aconcagua. The arrival of the storm, with fast dropping temperatures can be very swift, but 10-12 hours after the first signs is the norm.

When To Climb

The most common time to be in the area is from the beginning of December to mid March. This period has the highest temperatures and also the most stabile weather. Another factor to consider is how you like to be at one of the world’s most busy mountains at peak season. At the beginning and in the end of the above mentioned period there are less people around.

Red Tape

The color of Manso makes it...Manso seen from Nido

A permit for entering the Aconcagua National Park is necessary. The only place to obtain it is in Mendoza. The Permit office is located on one of Mendoza's main streets; San Martin. Ask for: Subsecretaria De Turismo or San Martín 1143. The permit office is not in the park anymore!

The prices for the 2005/2006 season were:

HIGH SEASON:From 15th December of year 2005 to 31st January 2006, a permit costs
• Climbing USD$ 330 20 days
• Long Trekking USD$ 50 7 days
• Short Trekking USD$ 30 3 days

MEDIUM SEASON: From December 1st to December 14th, 2005, and from February 1st to February 20th, 2006 a permit costs:
• Climbing USD$ 220 20 days
• Long Trekking USD$ 40 7 days
• Short Trekking USD$ 20 3 days

LOW SEASON: From November 15th to November 30th and from February 21st to March 15th of each year: 2005 - 2006
• Climbing USD$ 110 20 days
• Long Trekking USD$ 30 7 days
• Short Trekking USD$ 20 3 days

Note that the prices above are for foreigners. Argentinean citizens pay half of what’s stated above.
Validity of the climbing permits is 20 days from the day of entry to the park.

The permit has to be paid in cash over the counter in the permit office and is ready in ten minutes. A thing to think about is to have the whole amount of cash in one currency. I showed up with about 60% in Pesos and the rest in USD. It did not work and I had to rush off and change. There are money exchange bureaus nearby. Casa de Cambio, in Spanish.

The following is to be found on the back of your climbing permit:

You will have to pay a U$S 100 fine if you:
* Do not use the baths provided by the park.
* Throw garbage along the park, leave or do not use the numbered plastic bags provided by the park.
* Pollute rivers, streams or waterfalls.
* Enter either with bicycles or pets.
* Damage wildlife, plants and natural, cultural or archeological features which are protected by the park regulations.

You will have to pay a U$S 200 fine if you:
* Throw garbage, forget or loose the numbered bags in the high camps or during your expedition.
* Gather or burn wood in the park.
* Carve insriptions in the stones.

You will have to pay the equivalent of a 2nd permit or an ascent permit if you:
* Go beyond the limits of the length if the stay allowed in the permit or go higher than 4300 mts with short trekking (3 days), long trekking (7 days).

* Maximum stay is 20 days with ascent permit.
* Horcones ranger station open daily from 8 A.M. - 6 P.M.
* For your safety always check out.

Environmental issues and toilet business

When checking in to the national park in Horcones, the ranger in charge will supply you with a numbered garbage bag. You're supposed to put all the litter in this bag and return it at the gate when leaving the park.

When arriving in Plaza de Mulas or Plaza Argentina an official will register you and hand over a numbered "shit-bag".
This bag will be your companion all the time on the higher reaches of Aconcagua and if you loose it you have to pay a $200 fine.
You're supposed to use the bag as the only alternative for a toilet and if you're doing your business in nature and are spotted by the guards there is a $100 fine.
The plastic of the bag is not that thick and is not to be trusted. Double or triple pack it in order to avoid quite disgusting leakage in your back pack.

The whole situation can get quite absurd... A saw one team of climbers heading down at a break-neck speed, "so it was still frozen when arriving at base camp".

Plaza de Mulas Rules for camping etc.

If not part of an organized expedition, you have to "be contracted to a toilet service" at BC. We were asking around a bit and some big organizers told us the price was US$100, some smaller US$5/day or US$10 for the whole stay. If you used the toilet services between 20:00 and 08:00 you did not have to pay anything in some of the places. For those on an extremely low budget an alternative was to camp at the restaurant and use the toilets there.

As all this were new to everyone, there was a lot of confusion. Some zealots were very strict about the rules and some didn´t care at all using a free spot to squat themselves when nature called.

Budget accomodation in Mendoza

If you're on a tight budget or want basic accomodation in Mendoza, Hostel Independencia is a good alternative. It's conveniently located at the main park in the center of the city. The permit office for Aconcagua is a five minute walk away and so are the gear shops, restaurants etc.
The hostel is also a good source of info and there's a mountaineering agency operating in the hostel's premises.
This company can also provide rides to Cordon del Plata or Aconcagua, clean white gas and other useful things and services for a mountaineer.
They also organize whole packages for Aconcagua.
In early 2006 the price for a dorm was 20 Argentinian Pesos and a double went for 50.
1USD = 2,94ARP

Gear shops in Mendoza

There's one really good mountaineering shop in Mendoza.
Orviz is located on Juan B Justo, a little bit away from the main center.
See map.
The shop has all you can possibly need for any type of mountaineering.
Lots of gear for rent and sale.
Highly recommended.

There are a few more shops on Sarmiento, Las Heras and Suipacha in central Mendoza. El Refugio is a good one.



Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
