After an outstanding 2016/2017 with very high success we are excited to announce our 2017/18 offerings. This seasons offerings are marked by 2 route options
Vacas Valley Route: This is the tried and true route that we have been offering since 1990. Quieter, more aesthetically pleasing and the chance the traverse the mountain, this route employs three camps, ample rest and extra days; Aconcagua at its finest. More about Vacas Valley Route
Aconcagua Normal Route: A shorter and more direct route with lighter pack weight, that builds porter support into the program (our Vacas Valley has porter options as well). This trip is competitively priced and has days acclimating and a well-appointed base camp with less time on the higher mountain camps. More about Normal Route
We encourage you to review our Why Climb section
While not technical, Aconcagua is a highly underestimated climb, and traveling with Alpine Ascents and our near 30 years of experience, knowledgeable and expert guides will greatly increase your chances of summiting and being safe on the mountain. Essential logistics like food prep, quality camps, porters options and days on the mountains may seem like areas where you can “cut corners”, however we profess the importance of these details along with reasonable team sizes (many of our competitors end up combining teams and can have up to 20 with a few guides) are paramount to offering a superb experience.
I would not hesitate to join another climb with either guide. Exceeded expectations. Very professional. All camps and lodging met or exceeded my expectations. The tents were brand new. Food and group gear were excellent. I am a fan of AAI and will share my opinion when given the chance. – 2016 Climber
Over the last 25 plus years we have developed a superb system on the mountain, which affords you the best chance of proper acclimatization and summit success. Our Vacas Valley climb has numerous extra days built in to the itinerary as we methodically ascend the mountain with our renowned guide staff at the helm. With a seasonal location in Mendoza, we can respond to issues that arise quickly and a low climber to guide ratio offers a close attentiveness important in success and safety.
There may be many personal reasons to choose a particular guide service, but there are four main areas of concern that you should look at carefully: Safety Record, Guides, Logistics In-Country, and Pre-Trip Planning with the climber. In all four categories, Alpine Ascents ranks highest in the climbing industry. No other guide service has the safety record, quality of guides, finely honed programs, food, care, quality and customer service that we offer.
About the Mountain
Aconcagua, which translates as “Stone Sentinel” is 22,841 ft, making it the highest mountain in the Americas and the highest mountain outside of Asia. This spectacular mountain is surrounded by numerous peaks over 20,000 ft. and the surrounding lowlands (up to 13,000 ft.) consist of beautiful desert landscapes with a large diversity of flora and fauna.
Traditionally there are three guided routes on Aconcagua: Route Normal, Vacas Valley Polish Variation, and the Guanacos Glacier Route. (Please note the Guanacos Route has been closed for the past several years in an effort to protect the large number of guanacos that breed and raise young in the area). We choose to guide the Polish Vacas Variation Route on the east side of the mountain because it sees less traffic, much more aesthetic approach and give us the opportunity to traverse the mountain. We also offer the Normal Route which is shorter, somewhat less demanding and has a porter package built in to the ascent. An ascent of Aconcagua by any of these routes requires minimal technical skills but does require excellent physical condition and good backpacking and camping skills.
A Brief History
While the first summit of Aconcagua is credited to Swiss Climber Mathias Zurbriggen, there are traces of Inca civilization and culture near the summit. The name itself hearkens back to indigenous roots, the Quechua word Anco (white) and Cahuac (sentinel). Much like the explorers of the Himalayas, the passes around Aconcagua came into play during military expeditions. In 1817, General Jose de San Martin crossed the range in successful efforts to liberate Chile from Spain. By 1950 most sides of the mountain were climbed with variations of these routes being added to the long line of successful summits.
Summit Success at Our Home Away From Home
Simply put, we have had over 90% of our teams reach the summit.
In over 25 years of guiding Aconcagua, only a handful teams have not reached the summit – a team success rate of about 90%. We have led numerous expeditions in which all climbers have reached the summit. We are confident our summit success is the finest in the industry. The success is a testament to our guides and the hard work and team spirit of our climbers. Guides are well equipped, experienced and prepared to lead your climbs and properly outfit your climb as we keep a staff and apartment in the launch city of Mendoza. We believe that with our guides and acclimatization schedule, along with our pre-trip assistance, Alpine Ascents offers the best possible chance for you to reach the summit of Aconcagua.
Aconcagua has literally been our home away from home. Our extensive experience guiding Aconcagua (as well as other high peaks around the world) has produced outstanding and perhaps unprecedented success rates. Alpine Ascents International has a long-standing reputation of leading successful climbs as well as acting as a prime resource for guide books, climbers and the media.
We climb Aconcagua using both the Vacas Valley Route (Polish Variation) and the Normal Route.
This is a fully guided ascent, led by American guides who climb the mountain with you. We are one of the few outfitters that offer this type of support (and in turn, high success and outstanding safety record). It should be noted that many outfitters merely offer a supported trek, where a single guide facilitates the climb but does not act as a guide during the ascent.
Upon sign up we will forward our famed, comprehensive confirmation package. This package will include all of the details for your trip.
Climbers should have completed a substantial trek or climb and carried a heavy pack. We highly recommend prior crampin training or a program such as a 3 day climb of Mt. Rainier or Mt. Baker. Usually well worth your time is the completion of a climbing course (though a 3 day climb adequate) such as our, 6-Day Training course, 8 Day Training course, Alaska 8 Day Course, Alaska 12-Day Training course or have equivalent skills and experience. This climb requires very basic cramponing, and expedition camping skills. It is our goal to have similarly skilled climbers on our expeditions.

An Open Letter to those interested in Climbing Aconcagua
The following letter from Willi Pritte applies to any route or guide service on Aconcagua, there is no easy way up.
After nearly 30 expeditions and 40 summits of Aconcagua in the past 15 years, I have made many observations about the types of problems which prospective high altitude climbers tend to have most commonly, especially on this mountain.
First and foremost, many tend to underestimate the physical fitness needs of a high altitude expedition such as this. Yes, Aconcagua has the reputation of being an “easy” and “non-technical” mountain by normal routes (more on this later). This does not mean “non-physical” by any stretch of the imagination. Over the years, I have had many climbers on my expeditions who have climbed Denali before coming to Aconcagua. Almost universally they believe that Aconcagua is more physically demanding than Denali was for them. Take heed of this. The greater the fitness you show up with, the better you will tend to do and the more you will enjoy the expedition. At the very least this can mean that you can sit back and enjoy the afternoons instead of being whipped every day! It is also worth noting that less fit or overweight people are pushing themselves far more, and this additional stress can seriously adversely affect the entire acclimation process which is so important on high altitude expeditions.
Regarding the “non-technical” nature of Aconcagua: This is only true sometimes. There is much misinformation about this mountain both in guidebooks and on the internet. Like any big mountain, things can change frequently and rapidly. Often a climb of Aconcagua, even by one of its normal routes, can involve lots of trail-breaking in deep snow, and/or long traversing sections of hard ice where the knowledge and proper use of crampons and ice axes are critical to safety. (In fact, most trips in the past few seasons have required the use of ice axe and crampons during the climb.) If you have no mountaineering experience, these situations can be demanding but we still consider this a non-technical climb by mountaineering standards. If your only mountain experience has been something such as Kilimanjaro, Aconcagua is a big step up in challenge. Real technical mountaineering experience, such as our 6-Day course, should be considered first. Have you put a 50 or 60-pound pack on and climbed extensive mountain terrain? Are you comfortable with the use of crampons and ice axe when tired and looking down a long way? If the answer is no, then you need to get that experience before joining an expedition. Being both fit and technically competent for the challenges of an expedition is a very important part of being a productive team member. When you come to Aconcagua (or any expedition), you are not 10 individuals attempting to climb a mountain, you are part of a team functioning together to enhance the safety and enjoyment of the expedition. If you come unprepared physically, technically, or equally important, mentally, then you are not a productive team member and others must then make up for your deficits which negatively impacts the team and can negatively impact safety.
Be realistic about any personal limitations you may have. Do you have a history of heart problems? Make sure that you seriously consider what you are attempting to do on an expedition, and how physically demanding it is (and consult with your doctor) before you decide to join. Do you have exercise induced asthma? Realize that Aconcagua is a very dry and at times cold and at times dusty environment, probably the likes of which you have never experienced. Bring plenty of your normal meds and be prepared for the possibility that you may have abnormally bad reactions which may mean you will need to leave the expedition early. Whatever personal health limitations you may have, you never know how your body will cope with an environment such as Aconcagua until you try it a few times, so be conservative.
We do have porters available at an additional cost to assist with carrying loads and personal equipment, please contact us for details. (However, this does not mean one may be unfit, or technically unqualified.)
When properly prepared for this expedition, I’m sure you will be favorably impressed with the magnificent scenery, the culture, and the great climbing here. I look forward to meeting you and climbing with you in Argentina! You will occasionally read on the internet, or in magazine articles, or in guidebooks about how ugly Aconcagua is. I’m convinced that two types of people write these things. The first type have never been here in the first place and are only parroting what they have heard from someone else. The second type have no soul and don’t belong in the mountains anywhere!
Happy training and climbing.
Senior Guide, Alpine Ascents International
In the best interest of personal safety, success and team compatibility, adequate training and excellent physical condition are required. and be physically and mentally prepared to deal with strenuous situations at high altitudes. Climbers need to be in excellent physical condition for both personal enjoyment and to be an integral team member.
Climbing Skill Level
The Vacas Valley (Polish Variation) and Normal Route: While technical skills are not necessary, it is strongly recommended that climbers should have completed our 6-day mountaineering course, Rainier or Mt. Baker summit climb, or the equivalent.
Please note that this climb is far more demanding than Kilimanjaro. In addition to the physical demands, climbers should have spent multiple nights outdoors, winter camping, completed multi-day trips with a 40 pound pack ( lesser pack weight if porters used) and be able to assist guides with setting up camp and tents. Please use the training statement to determine what fitness levels are expected, we are happy to work with you on developing a training program. While some minimum standard such as being able to run a 10K in under an hour is helpful (and well below the marker of who will be successful), it is often hard to predict how non-mountaineering training will translate to Aconcagua.
From our training statement:
“A reasonable goal would be to ascend 3,200 – 3,500 feet carrying an average pack of 40 pounds in a two to three hour period, or roughly 1,200 – 1,500 vertical feet per hour.”
Training Statement From the Guides
“Although non-technical, this is a highly challenging climb and demands more than most other non-technical climbs (such as certain peaks in the U.S. and Kilimanjaro). This expedition-style climb requires the carrying of a heavy pack (if no porters) for multiple days, making prior physical training of three months or more critical to your success and enjoyment. We highly recommend our 6-day mountaineering course or Rainier/Baker for climbers who have not climbed with a heavy. pack or are unsure of the rigors that a climb such as Aconcagua requires. We stress these points to continue our high summit success and ensure that teams are well-balanced.”
Example on Itinerary Day 16: This is a single carry day where pack weight may reach approximately 55lbs. The weight depends on a number of factors including: weight of personal gear such as backpack, if extra days were used earlier in the trip consuming food and fuel, temperature on the day of this carry (if all clothing is worn).
This is a highly recommended shortlist and we would be happy to pass on a longer reading list for those interested. These links will bounce to Amazon.com with reviews.
The expedition was a balanced mix of struggle, hardship, reward and joy as I expected it. Willi exhibited an encyclopedic knowledge on mountaineering, equipment, S. America and all other subjects. He kept us well fed, safe, amused and comfortable. He is an excellent guide and an excellent person.
