Climbers at Nido de Condores...

Sunset at Nido

December 8, 2003. Moving up...

Hauling loads up to Camp 1 on the False Polish route

Aconcagua is the highest mountain in the Western hemisphere, located in western Argentina, near the Chile border. There are about 3,500 climbers trying the summit each year (info from 2002). The 'Normal Route' is non-technical - a walk-up, following the Northwest Ridge. It is the altitude that poses the biggest problem. That and the sense that this is an easy climb. Every year people die because or inexperience and/or they underestimate the task at hand. Respect this mountain and you will fare better. You should not attempt alone, you should always have someone watching you. Much of the hiking is on scree.

On the Normal and Polish Traverse routes there are no permanent snowfields, but crampons and ice axe may still be required in some sections. The Caneleta can have hardpacked snow with some icy sections that can be easily cramponed making the top section much quicker (in relative terms). So be warned many who neglect to bring crampons are turned back by these conditions. 

Note. Good news it appears that both sides of the mountain are now open (2022-2023 season).  I dont see a way to translate the informaion from Spanish to English like before but from what I am reading it appears that both entrances are open.
For when the park is open/ Water sources on the walk into Plaza Argentina can be few and far between. So be advised that you should fill up three bottles for the walk-in each day. The mountain itself should be OK for water. Lots of pipes at base camp (plaza Argentina). But you are supposed to only use the pipe of the Base Camp provider that you hired for your trip.

Getting there and currency issues, customs

Aconcagua on December 12,...

Aconcagua from Casa Piedra in the early morning.

Fly to either Santiago (Chile) then Mendoza (Argentina). Or Buenos Aires then Mendoza. Take the bus to Puente del Inca or Penetentes. The entrance to the National Park is either at Puenta del Inca (normal route and south face). Or the through the Vacas Valley near Penetentes (For the Polish Glacier, Polish Traverse and Vacas routes).
You must go to Mendoza Argentina in person to get your climbing permit. An issue if you go through customs at Santiago airport. There is a good chance that you will have all meat and dairy products from your expedition food confiscated upon entering Chile. Stay in transit and take a short (45 min) flight on Lan Chile or Aerolineas Argentinas to Mendoza, Argentina. This will allow you to keep your food, get your permits, possibly see Aconcagua from the air as they fly close to it at times, and save the 100-140$ U.S. tax Chile imposes on Canadians and other nationalities. This has been dropped for U.S. citizens.
If you are entering Chile by bus this will not apply.
Possible food issue. Our climbers had their bags searched in Mendoza Argentina for certain food items. While normally climbers are treated separately in this respects, as the foreign currency is valued we are not hassled. They confiscated some food items such as peanuts and items that had been repacked not in the original packaging. Among the items taken were believe it or not..gummy bears. We think the staff was hungry. I packed all my food in 3-day packs in separate stuff sacks labeled, base camp, camp one, and camp two. These were packed at the bottom of my bag under everything and looked like a hassle to get to and open. Thus the customs were reluctant to get that deep in the bottom of my bag.
The people that were searched had packed their food in clear plastic making the customs agent job too easy. So pack your food accordingly to avoid any unnecessary hassles. Note: this advice was good for the 1990's and the early 2000's. The surpermarkets in Mendoza now have ample supplies. So its is a toss up on whether to bring all your food and pay the fees the airlines now charge for heavier luggage. The costs are cheaper sometimes in Mendoza. But if you buy your food in Mendoza you will have to allot time to buy it and to back your food properly for the mules. Plus you also have to bring tape and bags to pack it all properly labelled for each camp. No big deal but something to consider.

Aconcagua from 2.5 hours out of Plaza Argentina

The Argentine Peso was devalued several years ago between 50-60%. The US dollar was widely accepted everywhere but receintly people such as taxi drivers were forbidden to take and had now way to exchange them
Exchange rates as of 25-11-2021 is 1,000 pesos equals 9.p USD or 1,000 equals 12.56 CAN dollar. But this can change daily.
Check out and compare the rate at the airport, your hotel and the various Cambios on San Martin. They are all about the same. See if your hotel will give you a better room rate depending on what currency you will be paying in. Some hotels and stores offer better rates if you pay in cash as opposed to using credit cards. When changing money in most cases you will be asked for your passport so keep it handy. There is a lot of suspicion of counterfeit bills especially 100 US. Try to bring down bills that are as new as possible. Older scruffy ones can and will be rejected.
In 2008 a steak dinner with wine can cost $10.00 USD at a sidewalk restaurant. Fancier places might cost you 20-30 which is still a bargain based on the quality of the service and food you will receive. This was about the same in 2013 the last time I was personally there. It is most likely more expensive. I will post an update if someone includes or I get down there again.

Permits 21/01/2019
To enter ACONCAGUA PROVINCIAL PARK, you have to obtain a permit.
You have to fill out the forms personally. Permits are sold EXCLUSIVELY at SUBSECRETARÍA DE TURISMO på San Martín 1143. Close to Plaza Independencia. 
Most cabs know where this is. When you apply for your permit in Mendoza you will get a ´banking slip´ from the park office, then go to a nearby "Locatario" to pay your permit fee. Then you will return to the park office and get your ´climbing permit´.The whole process takes one or two hours now, more with high season line ups. 
The information (pricing) posted below is for people outside of Argentina and South America. 
A more complete pricing structure is found here for Argentines, People from Mendoza and the rest of South America.

Proceeds from the duties are alloted (supposed to be) to the maintenance and protection of the ACONCAGUA PROVINCIAL PARK. The above pricing was what I could gather from the internet on November 22, 2016. Prices may be subject to change.
Off-season (from March 16 to November 14) access to the Aconcagua Park is no longer free. A permit must be purchased in Mendoza or at the Park Rangers’ Shelter in Horcones Valley. The price of admittance is the price charged during the high season even if the rescuing service is not provided. Neither doctors nor park rangers are available during this period. However, for a “special” price, there is an exception between March 16 and April 1st., of each season. To access the Aconcagua Park within these periods, for trekkings or to climb, we suggest contacting the Aconcagua Park’s authorities. There are restrictions regarding the access of MINORS to the Park: they will have to exhibit pertinent authorization signed by both parents and certified by Public Notary or their respective Consulate or Embassy. For further information, please, contact the RENOVABLE NATURAL RESOURCES BUREAU (Dirección de Recursos Naturales Renovables) located in General San Martín Park, phone + 54 261 425 5090 or + 54 261 425 7065 (from 08:00 AM to 01:00 PM) e mail:
The permits must be given in-person to each visitor and only in Mendoza. Trekking and tourism agencies are not authorized anymore to get the climbing permits for visitors as it was in the past. Each climber must come in person to Mendoza city to get it. The permits can not be bought either at Puente de Inca or Punta de Vacas. The control of permisses is done in laguna Horcones (normal and south face), the same as in the Rio Vacas (Polish and Polish traverse routes) by the park-rangers. Anywhere inside the park, the permit or the receipt may be required to be shown. (Passport or Identity Card required). Neither medical certificate or evidence of insurance are necessary.
Payment may be either in Argentine Pesos or in U.S. Dollars. No credits cards or checks are accepted. This should not take to long as the staff are normally pretty used to their jobs and are usually pleasent.
There now are doctors at the two main base camps. (Plaza Argentina and Plaza des Mules) You will after seeing the Rangers have to check in with the base camp doctor and will get an examination which will determine whether you are fit to go higher. This is mandatory now and a good idea.
  • Permits are valid from the date of entry to the Park
  • Argentine citizens are entitled to a 50% discount on the above prices.

Permit / garbage information from: Corax Date: Feb 05, 2005 11:26 PM

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 that 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 inscriptions 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 of the stay allowed in the permit or go higher than 4300 mts with short trekking (3 days), long trekking (7 days).


  • The 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.


On matters of poop n scoop

When arriving in Plaza de Mulas and Plaza Argentina when you check in the Ranger 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 lose 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. Be warned, 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 backpack. The best thing is to bring a number of smaller bags with you and bag it each time. Cache these smaller bags which should freeze overnight. You can then double bag these in the numbered bag for safer transportation to base camp. Your mule provider is in charge of making sure you have brought this and your numbered garbage bag down to base camp. If you lose it he won't sign your permit. If he does then he becomes responsible.

There are toilets at Pampa Lena (flush!), Casa Piedra and Plaza Argentina. Conflencia and Plaza des Mulas for the normal route. So it is in the upper camps where you will have to collect your waste.

If not part of an organized expedition, you have to "be contracted to a toilet service" at BC. Asking around a bit and some big organizers will tell you the price is 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 may not have to pay anything in some of the places. For those on an extremely low budget, an alternative is to camp at the restaurant and use the toilets there. You can always use the restaurants' toilet if you are giving them some business.

Ganesh Adventures Aconcagua trip 

January 2004

Mules on the walk in

Mules Each mule can only take 60 kilos (two 30 kilo bags balanced). So each duffle you bring should not exceed 30 kilos. As a rule clients are allowed 30 kilos including their food. Not including tents and communal gear. You will be charged two days in and one day back for the walk in in the normal route. For the walk out, it will depend on whether you hire mules who just brought gear in or if they came in empty just for you. Try to negotiate in advance for dropoff and pickup. Radios are useful here and the Rangers can be of great help. For the Polish side you will be charged 3 days in and one to two days out for the approach and its the same story for the walk out as on the normal route.

Mule prices can vary but it works to about 150 USD perday for and mule driver and two mules (120 kilos). This is only a guide things change depending on how desperate you are and availability, size of group. Eight people would use 4 mules (2x30 = 60 kilos per mule) plus probably 2 mules (2x60 kilos of communal gear). You would probably have three muleteers.

Just an example for the Polish Traverse - Group size - 3 people. December 2001 it cost for two mules in (three days) and one mule out (two days) including the Mule driver $ 750$US

Camps and possible itineraries

Shadow of Aconcagua in Clouds

The shadow of Aconcagua in the clouds

There are 5 routes listed on the left-hand side of this page. This section deals with the two most traveled, The Normal Route and the Polish Traverse.

20-12-06 Note the Quanaco route is reported to be closed to the public.. More on this as news filters in. The reason given so far is the perserve this unspoiled portion of the mountain. 


Looking North from the False Polish route

POLISH TRAVERSE If you go the Polish traverse route, allow three days at least for the approach. Here is how it can go. You can alter as you go depending on how you feel.

Possible itinerary

  • Day one- End of Vacas valley-Pampa laina (8,200 ft) From the road to camp 4-5 hours
  • Day two- Casa Piedra (9,200 ft) 5-7 hours
  • Day three- Plaza Argentina (13,200 ft) 5-7 hours
  • Day four- Rest
  • Day five- Carry a load to camp 1 (16,200 ft) 4-6 hours
  • Day six- Move up to camp 1 4-6 hours
  • Day seven- Rest
  • Day eight- Carry to camp 2 (19,200 ft) (high camp) 4-6 hours
  • Day nine- Rest
  • Day ten- Move up to camp 2 (19,200 ft) 4-6 hours
  • Day eleven- walk to 21,500 feet Independencia to understand the route 2-3 hours
  • Day twelve- get up early 3:00am and start for the summit with headlamps and crampons this is a long day allow 10-12 hours or longer for the round trip. 7-12 hours
  • Day thirteen- descend to base camp then arrange mules with the rangers for your gear and walk out to Casa Piedra to spend the night. 3-7 hours
  • Day fourteen-walk out to the highway at mouth of the Rio Vacas have you pick up scheduled in advance and have the rangers confirm it if possible. If not you will have to walk or hitchhike (which is difficult since it is so close to the border). You can always call the hotel at Penitentes from the truck customs building at the mouth of the Vacas. They will pick you up if you will stay or eat there. So have the number tucked away. 4-8 hours

On the Polish route, once you have reached basecamp at Plaza Argentina 13,300 feet (takes 3 days to reach). Then it's up to camp one at approx 16,200 feet. The next camp, Camp 2 is at 19,200 feet approx. From here you can go up the Polish Glacier or traverse over to the normal route at Independcia (21,500) and up to the summit. A camp is also possible at White rocks, approx 19,900 feet. This will aid you in removing the traverse at the beginning of your summit bid. But will take extra energy carrying all your gear over the traverse and setting up another camp. I don’t recommend it. I only mention it as some people do it. Camps 1 and 2 are not huge and space can be an issue at times. There is a larger flat area down to the right as you enter camp 2. Many people go there. But it is more exposed, so you had better make your tent extra bombproof.

Possible traverse submission by author: mconnell If you are going to do the "Polish Traverse", consider going out the Normal Route. It means you have to do a carryover of everything, but you get to see both sides of the mountain and can be out from high camp in 2 days. From Camp 2 at the foot of the glacier, traverse directly to White Rocks and head down. Took us about 4 hours from White Rocks to Plaza de Mulas. From William Marler. Yes this can be done but we haven't as yet as our groups have always brought more gear than was needed. ie food and extra clothes that were left in Plaza Argentina. As well as all the garbage including fuel canisters you have used up to base camp and above that you have to bring out with you. So we would have had to bring all that extra gear up and over the mountain. If you are a small tight group with your act together go for it. But bring all your garbage. 

erecting a tent as sun sets...

Erecting a tent at Berlin


On the Normal route, a two-day walk (overnight at Confluencia) will get you to a large basecamp (Plaza de Mules 13,500 feet approx). Stay on the left side as you enter camp (many loose boulders make there way down on the right side). Then up camp 2 or Camp Canada at 16,200 approx. This is a good acclimatization stop but has limited space sometimes. Some people continue up to Nido des Condores (approx 18,000 feet) which is a large area but can be very exposed to the wind and elements. It is also a very big push from basecamp at 13,500 feet and can break a lot of people. Camp 3 is at Berlin (19,300 feet approx). From here you can go to the summit easily if you have acclimatized well. I use the word easily loosely, most of you will know what I mean. Nontechnical but a real slog in scree. 

  • Possible itinerary
  • Day one- Puenta del inca to Confuencia.(9,200 ft) 3-4 hours
  • Day two- Confluencia to base camp. (13,000 ft) 6-7 hours
  • Day three- Rest day
  • Day four- Carry to Camp Canada (16,000 ft)4-6 hours
  • Day five- Move up to Camp Canada 4-6 hours
  • Day six- Rest day
  • Day seven- Carry to Berlin (19,100 ft) 5-6 hours
  • Day eight- Move up to Berlin (19,100 ft) 5-6 hours
  • Day nine- Rest day and trail exploration 2-3 hours
  • Day ten- Summit day 8-12 hours round trip 8-12 hours
  • Day eleven- Clean up camp and decend to basecamp.3-4 hours
  • Day twelve- Arrange mules and walk out to Puenta del Inca or Confluencia 6-8 hours
  • Day thirteen- Walk-out if you camped at Confluencia 2-3 hours

Note: Add extra summit days for bad weather. 

Camp Cólera

Camp Coléra


Author: Alpinist Date: Dec 30, 2005 12:30 PM The conditions at Camp Berlin were quite poor when I was there in December 2005. There was human feces and toilet paper under every small rock, garbage everywhere, and the strong smell of urine in the air. As an alternative, consider camping at Camp Coléra. It is only ~200 feet (70 meters) higher than Berlin and much cleaner. Upon arrival at Berlin, take an immediate left. Follow the trail that traverses the ridge towards the black rocks near the top.

  • From Seven Summits my 7 summits pages for more info, a complete trip report and 80+ pictures of the mountain.

    Possible food list

    Sunset from Camp Alaska

    Sunrise from "Camp Alaska"

    What food to bring? Basically it boils down to what you can carry and prepare easily. Also what you feel your body will crave and digest when (as in most cases) your appetite diminishes as you gain altitude.

Here are breakfast, lunch and dinner suggestions

Breakfast Bag of cereal Milk powder Box of raisins Small tinned fruit Piece of cheese Hot chocolate or coffee or tea Breakfast bar granola

Lunches Granola bar Chocolate bar Bag of mixed nuts Piece of cheese Crackers Tin of salmon or tuna or ham or sardines Cookies Juice crystals

Dinner Cup of soup(s) Japanese noodles Freeze-dried dinner Tin or foil pouch of beans Small tinned fruit CookiesTea or Hot chocolate

Snacks Granola bar Chocolate bar Peanut Butter tubes Bag of mixed nuts Piece of cheese Cookies Dried apricots or similar Pringles chips Honey tubes Power bars Cliff bars Squeeze gels (Energy)

Local food for the walk to base camp Bread or rolls Summer sausage Cheese Hard-boiled eggs Oranges and Apples

The next chore then is organizing your food into logical packs for transporting to base camp and each of the higher camps. The following is what I use as a guide for doing the False Polish route. It is a guide only as I add or subtract according to clients' preferences.

Pack 1 for walk-in Three Breakfasts (Pampa Lenia) (Casa Piedra) (Horse Fly/Intermediate camp)

Three Lunches and Snacks (way to Pampa Lenia) (way to Casa Piedra) (at Horse Fly/Intermediate camp)

Three Dinners (Pampa Lenia) (Casa Piedra) (Horse Fly/Intermediate camp)

Supplemented by fresh produce Bread or rolls Summer sausage Cheese Hard-boiled eggs Oranges and Apples

Pack 2 Basecamp Three Breakfasts (Basecamp) (Basecamp) (Basecamp)

Three Lunches and Snacks (on carry to camp one) (on carry to camp one) (at camp one)

Three Dinners (Basecamp) (Basecamp) (Basecamp)

Pack 3 Camp 1 Three Breakfasts (Camp one) (Camp one) (Camp one)

Three Lunches and Snacks (on carry camp two) (on carry camp two) (on move to camp two)

Three Dinners (Camp one) (Camp one) (Camp one)

Pack 4 Camp 2 Three breakfasts (Camp two rec) (Camp two summit) (Camp two descend day)

Three Lunches and Snacks (on rec to Independencia) (on summit day) (on summit or decend)

Three Dinners (Camp two) (Camp two summit) (Camp two summit day 2)

Pack 5 Walkout One breakfast (Casa Piedra)

Two Lunches, Snacks (on walk to Casa Piedra) (on walk out to road)

One Dinner Dinner for one night (Casa Piedra)

On both sides of the mountain that are mainly used (I don't know about Plaza Francia), there are those who provide food for a price. These may include papas frita, omelets, pizzas, different casseroles, and lasagnas. These can be a wonderful addition to one's diet and well being. But a word of caution. While I have had many a great meal and suffered no ill effects. Some people have come down with intestinal problems after partaking in some of these feasts. Basecamps are dirty places and while the food providers do their utmost to keep things sanitary slip-ups do happen. These Food tents are usually available starting mid-December.

Bon appetite!

Aconcagua records 

Looking at Aconcagua through...

Penetentes on the route up to Camp 1

Here are some records from the web site

  • FIRST Ascent First assent of Aconcagua was led by the English alpinist Edward Fitz Gerald, during the summer of 1897. Fitz Gerald's group acceded to the stony slope of the Northwest side of the mountain after following upstream the Horcones River. After several tries, the Swiss Mathias Zurbriggen reached alone the summit the 14 Th. of January, 1897. Followed a few days later by Nicholas Lanti and Stuart Vines, members of the same expedition, made the second climb following the same route.
  • FIRST ARGENTINE Ascent Lieutenant Nicholas Plantamura of the Argentine Army reached the summit the 8th of the 1934 in company of the Italian alpinists P Ceresa, P Ghiglione, R Chabod and the Chilean rancher Mariano Pasten. They climbed along the normal Route.
  • FIRST Ascent OF THE POLISH GLACIER In March 1934, The Polish V. Otrowski, K Narkiewicz, S Daszinski and S Osiecki opened a new route to the summit along the beautiful Northeast Glacier, doing also the eighth assent of the mountain. Since then the glacier is called the Polish Glacier.
  • FIRST Ascent BY A WOMAN Adriana Bance from France, on the 7th of March, 1940, accompanied by Jorge Link from Germany and the members of del club Andinista Mendoza, Pablo Franke, P Etura, D López y J Semper.
  • FIRST Ascent OF THE SOUTH SUR It was done by the French Adrienne Bance, the 7th. of March 1940, in company of the German Lopez Link and Members of the Andinist Club of Mendoza, Pablo Franke, P Etura, D Lopez and J Semper
  • FIRST Ascent OF THE SOUTHERN SUMMIT The German T Koop an L Herold reached the Southern Summit of the Aconcagua in January 1947. They followed the Normal Route until the middle of the Canaleta , then they turned to the right (west).

Avoiding Altitude sickness

Tent and Cloud

Tent at Camp 2

You should be prepared for the possible onset of altitude sickness. High altitudes are stressful on the body, and lack of oxygen up high can produce slightly debilitating effects, such as fatigue, headaches, shortness of breath, loss of appetite, nausea, and a drunken gait. Altitude sickness generally doesn’t occur below 10,000 feet, but people have suffered its symptoms lower than 8,000 feet.

There’s not much you can do to prevent this problem, but there are ways of alleviating its effects. The key to doing this is simple: take it easy. Take a day or two before beginning the walk in to acclimatize yourself to the elevation. Go at your own pace, and don’t take chances. Even if you’re in excellent shape, don’t be fooled. The lack of oxygen at such high altitudes can definitely throw your lungs for a loop. Walk at a comfortable, slow pace and don’t carry too much weight. Make sure to hydrate yourself regularly, drinking 4 to 5 liters (Nalgene bottles) of water per day; camelbacks can be mountain companions because of their convenient water portability. The only problem being keeping the nozzle clean, I find they can get gross and need constant cleaning.

My self, I attach a 1 liter Nalgene bottle to each side of my backpack so that I can reach them easily without removing my pack. Taking antioxidant vitamins (A, C, and E) also helps reduce the effects of high altitudes. Of course, working out before you go is another great preventative measure. While this doesn’t guarantee an easier time when up high, it can enhance your lungs’ ability to cope with the challenges of high elevations.

Try to spread out your ascent over a period of two or three days to give your body more time to adapt. Play by the “climb-high, sleep-low” theory of ascent: go on a short hike to a higher elevation, then return to the (lower) elevation at which you’ll sleep. Physical fitness, as mentioned above, is no guarantee against developing altitude sickness. Past excursions to high elevations without developing symptoms is similarly no guarantee against getting sick. There’s no way to predict who is more susceptible to altitude sickness although trekkers who overexert themselves, those who are panting or breathless, and those who stagger far behind the rest of the group are likely candidates.

Surefire signs of impending illness include extreme fatigue, headache, loss of appetite, and shortness of breath. If you experience any of these symptoms, the best thing to do is take a break from climbing for a couple of days to acclimatize. Once the symptoms disappear, it’s safe for you to continue. If the symptoms persist or get worse, you should descend to a lower elevation.

More serious levels of the illness include increasing tiredness, severe headaches, vomiting, and loss of coordination, and are indicative of acute mountain sickness (AMS). If such symptoms appear, don’t hesitate to get immediate medical attention. If serious symptoms go ignored for more than 12 hours, they could have dire--even fatal--effects, such as accumulation of fluid in the lungs or brain. The most important symptom of AMS is loss of coordination.

If someone staggers or walks in a drunken gait, check them out for further signs of AMS. A good test is, essentially, the police’s test for drunkenness--ask the person to walk in a straight line, placing one foot directly in front of the other without staggering or losing balance. If the person cannot perform, he or she should descend immediately--and never alone. Go slowly and without exertion, and ideally while it’s light outside. The descent should continue until symptoms begin to decrease; relief usually occurs within 1,000 to 1,500 feet.

There are prescription drugs out there that you can take for severe symptoms. The most common is called Diamox; it works by stimulating your breathing. Diamox is a strong medication and has some slight side effects, such as an annoying tingling in the fingers and toes. You will urinate more frequently so getting out of the tent at night in a storm could be a problem (if you don’t use a pee bottle). This will also necessitate you drinking more fluids to compensate. Do not take more than prescribed (some people get really sick), while I avoid taking it, many people find it helps them. My suggestion would be to try it out at home before you head to altitude so you will get to know the symptoms and side effects beforehand. Then when you take them up high you will have a better understanding of what it is that is making you feel this way.

Hotel Nutibara The Hotel Nutibara in Mendoza is a good bet, you can find cheaper and more expensive lodging but the pool is the best. 2005 rates below. They will allow you to store gear at the hotel and understand climbers' needs (ie will help you get in touch with mule providers).

I have included the Spanish because if you rent a room here or other places in Mendoza you will have to know these phrases to get what you want.

The Hotel Asylen in Penitentes is another, the food is good and the price is reasonable. There is a hostel next door next to the gas station where the food is good and beds (bunkbeds) are cheaper but you could be 6 to a room.

Hotel Aconcagua San Lorenzo 545, Mendoza, Argentina Hotel Aconcagua This is a very nice hotel with lots of services. On the more expensive side.

Park Hyatt Mendoza Five-star hotel. Formerly the Plaza Hotel. This amazing place combines the old grandeur of Argentina with ultra-modern facilities. Not a place to hang out for scruffy climbers. But if you like the finer things in life and can afford it. It is a beautiful hotel. (Especially if you have seen it before the renovations). Casino in the back for those inclined.

Climbing out of season

Re: Out of season climbing Author: Boris Krielen Date: Apr 17, 2002 08:35 AM

Hey William, I have climbed Aconcagua and reached the summit on Friday 29th of March 2002 during the Viento Blanco, the terrible snowstorm. As I was going to high camp, I was the only one in the park, quite an exclusive experience! After the summit, going down through the fresh snow was pretty cool, though route finding becomes more difficult and dangerous of avalanche grows. Route finding during the Viento Blanco is extremely hard. GPS can be a help. Local brochure has a list of waypoints. I didn't take a GPS. In advance, government people told me by e-mail to pay US$ 200 for the permit and US$ 70 more for several legal services and notary-papers. This turned out to be all nonsense. I paid 40 pesos at the entry of the park. Entering the park in high winter - June/September - might be more difficult though. Government and park officials indeed don't encourage this. Danger of avalanche is huge then.

After 16th of March there are no mules available from Puente del Inca or Punta de Vacas. Mules are not allowed into the park between 16th of March and 15th of November. Outfitters bring the mules down to Mendoza for the wintertime. Therefore I was the mule myself, carrying 32 kilo's. That's the way a real solo-expedition should be like, I think.

There are no wide rivers to pass on the normal route. On route to Plaza Argentina (Polish Glaciar) the river has to be passed at least twice. This could be a problem without mules. Until July, don't count on snow bridges to cross the rivers lower in the valley. Take a towel and light shoes!

Thanks Boris

A bit of good news

Chile no longer charges the $140 reciprocity fee for Americans to enter by plane, as the U.S. has dropped the tourist visa requirement for Chileans. One less issue if traveling via Santiago...
