    Should I join a scheduled expedition group?
    Our expeditions are perfect for those traveling alone or couples who want more company. We limit expeditions to 12 clients with groups made up of climbers from all around the world of varying ages.
    While most climbers join scheduled climbs, private expeditions can have more personal attention. This program’s flexibility makes it suitable for any type of situation during the ascent and allows for the possibility to make changes in the plans before the flight. Private clients are also able to select the starting date during the summer season.
    When is the best time of year to go?
    Summit attempts are permitted  from mid-November until the last days of February, due to the extremely harsh weather conditions such as low temperature and intense snowfalls starting in autumn until early spring. The trekking permits to enter the park (to the base camps only) are given until the end of March.

    The High Season in the Park starts in mid-December and lasts until the end of January. During this period of time, the affluence of mountaineers increases as a result of more stable weather conditions, increasing the possibilities of success on reaching the summit. AMG will assist in obtaining the necessary permits to enter the Park.

    How many days do I need?
    Our expeditions last 19 days as we feel the right amount of time needed to acclimatize as well some contingency for bad weather.  We recommend not attempting to climb Mount Aconcagua with a guide service offering less than 17 days.
    Can I pre-acclimatize to perform better at altitude?
    Our expeditions include time to acclimatize but we also work closely with those coming pre–acclimatized (either from prior mountains or Oxygen tent systems). We are happy to put together a private expedition based on your needs.
    Our trekking programs generally schedule at least two to three days over 4,000 m. Within this time, you will have exposed your body to altitude and will have started the acclimatization period. Do not hesitate to consult us with any questions.
    Who answers my questions before, during and after my booking?
    Our Customer Service staff gives personal attention to client’s specific questions. They will advise, inform, and make suggestions about all the aspects related to your expedition.
    Our team guides are passionate, experienced, and committed to providing all climbers the best experience possible.
    What are the requirements for a reservation? How much do I need to pay?
    The Booking procedure has two parts. First, complete the Booking form through our website; Second, make an advance payment using our international bank account or a credit card. To learn more about this procedure, please contact Customer Service.
    What is the maximum number of people in a group?
    Thirty-five years of experience has taught us that the maximum number of climbers for an all-around successful expedition is 12. In our private expeditions (where the climber chooses the starting date and the expedition group), sizes can vary based on your needs.
    How are climbers paired in hotels and tents?
    People who are alone will share a double room with a partner. We will try to accommodate people of the same gender, but if not possible, we will discuss options. Hotels in Mendoza have double rooms. Penitentes has rooms for four to six climbers. On the mountain, expedition tents accommodate two people each. Only in the high camps, and if the guide considers it convenient, three climbers may sleep together. Please contact us for single tents or single room at an additional cost.
    What if I have dietary restrictions?
    If you need a special diet for any reason, please let us know in your Personal Information Form so that we may take prepare specific meals for you during the expedition for an extra cost.
    What does AMG need to know about my health status?
    When making a reservation, you will be asked to fill in a Personal Information Form. This will help guides when assisting with any medial issues.

    If you are 65 or older, you will be required to show a medical certificate that you are in well enough physical and psychological health for the expedition.

    How difficult is this expedition?
    Technical Difficulty: The classic routes used in Mount Aconcagua (Normal Route, Polish Glacier Traverse, and Vacas Valley Route) are not technically difficult, meaning the participant does not need to have any previous climbing experience on rock or ice.  Crampons and fixed ropes may be required. Climbers are expected to have strong self care skills usually only obtainable with prior mountain experience
    Physical Difficulty: This is a highly demanding climb and climbers who are successful are usually in a 4-5 month mountaineering-based training regimen prior to the climb.
    Other Difficulties: The biggest problem climbers face on expeditions is the effect of altitude on your body. Overcoming this is directly related to correct acclimatization (an aspect we cover widely in our programs) and fitness level. Low temperatures on the mountain and multiple days in the field are additional obstacles that climbers face.
    How can I know if I am trained enough?
    Prior experience is often the best guide but those preparing properly should have 4-6 months of mountaineering-style preparation (carrying a pack with weight up steep incline or in gym). Most successful climbers are training 4-5 days per week in the 4-6 months leading up to the expedition. Please contact us for assistance with finding a training regimen.
    What is the skill level of this climb?
    How do I book my flights? When do I arrive/depart?
    Please follow the itinerary AMG will send upon your booking or contact us to request itinerary for your climb.
    What gear do I need for the expedition?
    Please see our gear list.
    Can I reserve extra nights before and after the expedition?
    Of course! In fact, we highly recommend arriving one day before the expedition.
    Please contact our Customer Service Staff for help in arranging additional nights in hotels included in our programs. You may also book additional night after the expedition finishes.
    What if I have to cancel my expedition?
    Cancellations must be made by written notice without exception (email is fine) up to 26 days before the start of the expedition. Your initial reservation deposit will be valid for life so provided you notify us at least 26 days prior to the start date, you may use it at a later time or transfer it to someone else.
    Should I buy travel insurance?
    Travel insurance is not required to participate in our expeditions. However, we highly recommend having coverage for at least medical care, emergency evacuation and, if possible, baggage and personal items loss as well. This will likely be the only way to get any refund if outside of our policies. This type of insurance can reimburse you for a number of expenses such as – cancellation, evacuation, early departure (limited to injury/illness), missed flights and lost luggage. Please contact us for recommended companies.
    Are tips included? How much do I tip?
    Tips are not included in the price of the expedition. We consider tips an expression of your gratitude and satisfaction for those who helped you throughout your expedition, so they are entirely up to you—there are no percentages and stipulated amounts. Normally, all members of the group collect money and give it to the main guide, who will divide it with his or her partners on the expedition. Tips for the camp staff and porters are separate.
    Do I need a climbing permit to climb Aconcagua?
    Yes. To enter Aconcagua Provincial Park, it is obligatory to get a permit. AMG will assist with the permit and process. Main season permit fees are about $1000.
    How are communications handled in the mountains?
    We have base stations linked all around the mountain, which we use to communicate via VHF and BLU radio among the High Camps: Plaza de Mulas, Plaza Argentina, Confluencia, Puente del Inca, and Mendoza.

    All our guides carry a VHF radio and they are in permanent communication with our Base Camps, the rescue patrol and the park rangers from every place in the park. In case of emergency, assistance can respond almost instantaneously. We also have a satellite phone in each base camp.

    How does AMG manage human waste?
    We are dedicated to taking care of the environment and hire porters and mules to carry all waste down from the mountain.
    What happens if we have bad weather?
    We schedule two extra days in our itineraries in case of bad weather. Owning and running all of our own services allows us the flexibility to work in additional days if necessary.
    What happens if I have to leave early?
    In case of illness or other personal issues, we can help arrange transport down the mountain for an extra cost, otherwise expedition prices are based on each team member’s participation for the entire expedition.
    Who carries our gear to high camp?
    ACONCAGUA MOUNTAIN GUIDES employs porters to carry climbers’ gear to High Camp  so they can keep their energy focused on the summit day.

    Each climber will carry part of the food and equipment (10 kg at most) to High Camp. This is very important to part of learning how you will respond physiologically to the higher altitude.

    Likewise, on days the group moves toward the high camps, team members will carry personal equipment and, without exception, food and equipment (5 kg tops). Porters will carry tents and other mountain equipment.
    When descending to Base Camp, porters will move all previously mentioned equipment, including garbage.
    Each member of the expedition must carry his or her personal gear in every section of the route, as well as food and the expedition equipment. If you would like to hire a porter to carry personal gear for an additional cost, please contact us and we can help arrange this.

    Who prepares our food and water?
    We hire professional nutritionists to carefully organize the meals for our expeditions. These meals take into account daily calories, taste, and variety. At Base Camps, chefs will prepare meals, and at the high camps, guides will prepare both food and water.
    How can I charge my devices during the expedition?
    In Penitentes you can find 220V power sources. While on the mountain, depending on the route, there are different options.

    On the Normal Route, we have generators in Confluencia and Plaza de Mulas Base Camp with equipment sockets to supply 220V and 12V power. In Confluencia, we are only able to use the generator for one hour per day, either in the morning or in the afternoon, to charge batteries for lighting up the camp at night. We can use the generator at Plaza de Mulas from 7: 00 p.m. to 11:00 p.m. for the same purpose.
    On the Vacas Valley Route toward Plaza Argentina, the generator works like in Confluencia, one hour only.
    At High Camps there is no electrical power supply, so we recommend you bring batteries or portable solar panels to change your devices.

    Why is my feedback so important to AMG?
    Feedback about your experience in Aconcagua is a very important part of our ability to continue offering our clients the highest quality adventure experiences. At the end of each climbing season, we review and discuss every aspect of the expedition with our staff. We are extremely grateful for all comments and suggestions.


    Setting us apart from other Aconcagua climbing and guiding services

    AMG’s staff and guides have a 36-year history of organizing and leading successful climbing expeditions to the summit of Aconcagua. AMG employs outstanding guides, and provides excellent Base Camp services, well-appointed gear, and itineraries that allow for proper acclimatization so each climber has an excellent chance of reaching the summit. Our level of care, commitment to quality, and focus on each climber’s experience have always been the hallmarks of our operation.

    Thank for you reaching out. We indeed reached the summit, and did so on a spectacularly beautiful day: sunshine, very little wind, and fairly warm weather (only -10 C or so). We had an amazing experience with our guide, Matoco. We would not have had such a perfect ascent and a safe trip overall had it not been for him. Other aspects also worked really well: we were warmly welcomed by the AMG staff at Confluencia and Plaza de Mulas. We got ample warm water (knowing we did not officially have any base camp support) and a small tray of fresh fruit and juice when we returned to basecamp after summiting. The mules and porters were all on time and nothing went amiss. All in all, we are super happy with AMG and our trip could not have gone any better! Christoph Dankert – Germany – & John Petito – USA

    Our guides, known to be the finest on the mountain, lead not only AMG climbs, but also trips for other renowned guide services in our industry. Several of our lead guides have ascended Aconcagua over 30 times, and all are certified by AAGM (Argentinean Association of Mountain Guides), and the EPGAMT (School of High Mountain and Trekking Guides) — the two highest certifications in Argentina. All of our guides are well-vetted, as we believe guides play a vital role in our clients’ experience, and we understand our reputation truly lies in their hands.

    We guarantee our guides have an thorough knowledge of the mountain, are well-trained, and understand the personal nuances of guiding others (great climbers do not always make great guides)

    Learn more about our expert guides on our About Us pages.

    Small teams and guide ratio
    On both the Normal and Polish Traverse Routes, our expeditions are limited to 12 climbers and are often smaller. Our climber-to-guide ratio is one guide for every three to four team members on the mountain. Small teams with low climber-to-guide ratios allow us to more readily assist climbers, which translates to higher rates of successful climbs to the summit.
    Itineraries with adequate acclimatization days
    We offer a 20-day, round-trip program from Mendoza, which is longer than programs other companies offer. The additional time we spend on the mountain increases your chance of successfully reaching the summit, and is a prime example of how we put quality first. Extra days allow us to wait out bad weather or have extra rest days if needed. Other teams might retreat early because they have run out of time or have moved too quickly up the mountain, which often causes climbers to become ill. If we finish on time or early, you will have time to enjoy the beautiful city of Mendoza and surrounding wine county, or fly home. See Climbing Itineraries for both Normal and Polish Traverse Routes.
    Porter assistance
    We employ porters at no additional cost to carry part of our group climbing gear on the mountain to keep climbers’ backpacks at reasonable weights. They will also carry human waste and trash back to Base Camps, move tents between all camps, and carry all group gear between Camp Canada and Nido de Cóndores. If you would like to hire additional porters to carry all your gear between camps, you can do so at an extra cost. Most climbers packs are about 40lbs.
    Base Camp Services
    AMG has three well-established Base Camps that provide a very high level of comfort and care. These camps are:
    – Confluencia
    – Plaza de Mulas
    – Plaza Argentina

    All camps are fully equipped with dining tents, tables, chairs, light, storage tents, clean toilets, electrical charging stations, and platforms to set up sleeping tents, as well as dormitory tents with bunk beds. The camps are run by a very conscientious and experienced bilingual staff and include professional chefs to prepare your meals. Other amenities at both Plaza de Mulas and Plaza Argentina include:
    – Wi-Fi throughout the camp
    – Showers

    Owning our own resources

    At AMG, we own all of our logistical services, including Base Camps, climbing gear, and mules, which allows us to operate quality trips at competitive prices.

    • AMG owns offices and depots in both Mendoza and at the entrance of the park. Climbers can utilize services at each of these depots. Our full-time, well-trained staff are ready to address your needs, whether in Mendoza or on the mountain 24 hours a day, 7 days a week.
    • We own over 140 mules, which allows us to easily transport all of your equipment and supplies to our base camps.
    Environmental stewardship and ethics

    AMG holds itself to the highest standards of environmental practices. We support the Provincial Park’s mission to preserve natural resources. Some of our commitments to this endeavor include:

    • Employing porters to remove all human waste from the mountain and then having it helicoptered out of the park for disposal.
    • Removing all trash from the mountain, with AMG mules carrying it out of the park for
    • Using LNT (Leave No Trace) principles throughout the
    • Caring for our mules with annual medical checkups and sufficient rest days between trips up the mountain.
    AMG Commitment

    Climbing Aconcagua is a large undertaking requiring a commitment to training, time away from work, and financial expense. We understand your commitment and are dedicated to providing you the best opportunity to reach the summit. There may be many personal reasons to choose a particular guide service, but the four main considerations of any guide service should include: 1. A company’s safety record, 2. Quality of guides, 3. Logistics in-country, and 4. The extent to which a company offers pre-trip planning assistance. AMG is a leader in all these areas.

    More than 30 years of experience

    Aconcagua Mountain Guides (AMG) is a full-service company offering a complete range of logistical services as well as guided climbs of both the Polish Traverse and the Normal Route of Aconcagua. AMG is an Argentine company based in Mendoza whose administrative staff has over 30 years of operational experience on Aconcagua. We provide logistical services and climbing expeditions for other renowned companies.

    In the last 12 years alone, we have operated 500 commercial expeditions to climb Aconcagua with 3,500 climbers from around the world. In addition, we have supplied logistical support to over 800 climbers.

    Our summit success rate and safety record are both the best in the industry. We continue to review programs for safety, customer satisfaction, and environmental practices.

    AMG Philosophy and business practices

    Our philosophy is to offer the highest standard of service to our clients and cater to each individual’s needs. We maintain a high standard of business ethics with all companies and people we do business with and provide good salaries to all our staff.

    AMG is a strong advocate for the environment and the protection of Provincial Park’s natural resources. We remove all human waste and trash from the mountain by mules and then have it helicoptered out of the park for disposal.

    We take very good care of our animals (we own over 140 mules), giving them quality feed, regular veterinarian check-ups and plenty of rest between carries to Base Camps.


    AMG has an excellent safety record. When making decisions or organizing expeditions, we focus on safety first. All staff members take part in our risk management and emergency response programs to ensure each expedition and trek is as safe and rewarding as it can be on the mountain. Our staff, both in the office and on the field, are ready to respond to emergencies if necessary. Within our own teams and the general climbing public, we are committed to safety on the mountain.

    All AMG guides are medically trained and carry first-aid kits to handle emergency situations that may arise on the mountain (this is important not just for emergencies, but for making decisions that will help clients properly acclimatize and stay fit). All teams have emergency oxygen with them at all times, even while climbing between camps. All guides carry VHF radios to communicate with other guides and Base Camps, giving them the ability to get weather forecasts, or request additional porters or assistance in case of emergency.


    All our base and approach camps are equipped with a system of communication via radio frequency, VHF, and phone. The aim is to be permanently connected with the headquarters in Mendoza city and with all our expeditions on the mountain. This allows us to facilitate those coming off the mountain whether scheduled or unscheduled in a timely manner. Should an emergency occur we are in close contact with Rangers and the helicopter service to move climbers efficiently to additional services off the mountain.

    Mules & AMG's Los Puquios Depot

    AMG owns a climbing depot/mule ranch at Los Puquios, which is near the entrance of the park, allowing us to provide safe gear storage and the ability to quickly send gear up or down the mountain. All 140 mules are based here, as are our “arrieros” (mule drivers) and a full-time staff to manage loads and assist groups. We can provide freezer space for food for those companies making multiple trips or who need fast resupplies.

    Highest quality gear on the mountain

    We use the highest quality climbing gear and all our equipment is well-maintained and replaced regularly. We are fortunate to have good relations with many gear manufactures around the world, allowing us access to the best climbing gear in the industry. We are the only company whose entire fleet of tents are North Face VE 25.

    Helicopter services

    We work directly with the only helicopter service on the mountain. We are able to call them anytime for a rescue, or to make arrangments for people who would rather fly down from Base Camps instead of hiking out. Many of our clients charter helicopter tours around the mountain. There are incredible views and excellent photo opportunities from the air.

    Transport services

    AMG can arrange all transportation needs for climbers while in Argentina, including airport pickups, round-trip transportation from Mendoza to Aconcagua, or any other excursions, such as tours to beautiful Argentinian wineries.

    24 Hour assistance

    As we are a local outfitter with strategic points of communication and can solve any unexpected issue that might occur, and we offer 24/7 bilingual service. We have a staff of professionals and experts who are available to assist whenever necessary, before, during, or after your expedition.

    Base Camp medical facilities

    Both in Plaza de Mulas and Plaza Argentina, the Provincial Park has medical facilities operated by doctors with experience in high-altitude and emergency medicine. AMG has additional medical equipment, which includes: portable oxygen, emergency first-aid kits, and digital oximeters. All teams have emergency oxygen at all times, including when climbing between camps. Our staff pay careful attention to every climber and will be ready to assist if they detect any mountain sickness problems or other health concerns.

    Giving Back

    AMG is committed to working with a variety of social institutions and scientific research to build a better world. The government of Argentina has acknowledged our social contributionss with distinctions. Some of our efforts include the following:

    • For more than 3 years we have been assisting teachers and directors from a kindergarten that serves low-income children. Each year, when classes start, we make important donations of food, supplies, and clothing that they use both for activities in the classroom, and to help compensate for some of the children’s basic necessities.
    • We have joined with Las Heras Municipality to establish a dining room for children and teenagers from Uspallata, the closest town to Aconcagua.
    • We donate medicine to the nursing section of the Argentinian Army Detachment in Puente del Inca. It is the only functioning medical facility in the zone.
    • We actively collaborate alongside Aconcagua’s Rescue Patrol with donations of technical material for rescue operations and participation in search and rescue services when needed.
    • For more than five years we have supported the SIGMA project, a project to investigate continental drift. In order to do this, scientists have installed censors in Mount Aconcagua – from the base to the summit ‒ that are monitored via satellite. This project is endorsed by the National Scientific and Technical Research Council of Argentina, and supported by other international educational institutions, such as Ohio State University, as well.
