Aconcagua, Argentina


Welcome to Aconcagua (22,841’/6,961m), the highest mountain outside of the Himalayas, the highest in the Americas, and one of the Seven Summits. Technically easy, Aconcagua is a mountain not to be underestimated. The altitude and the sometimes cold winds (a.k.a. El Viento Blanco) provide a challenge that any mountaineer should respect. Climbing Aconcagua is more than just the climb – the culture of Mendoza, the long, dramatic valleys, the international scene at basecamp, and the remote feel of the mountain provide a full experience that is unforgettable and satisfying on many levels.


What makes CMS different? There are a handful of top-quality Seven Summits companies and a plethora of lower quality Seven Summits companies to choose from, and with many of these companies you will have a good chance of summitting Aconcagua. The weather, your ability to acclimate and function at altitude, the itinerary of your trip, and the attentiveness of your guides are the four main factors in your chances for success. CMS is not a cookie-cutter, mass production company. We don’t send multitudes of people up the same mountain over and over again. Our diversely experienced senior guides are highly skilled and often certified in a variety of disciplines. Because our career guides depend on return clients to maintain a year-round schedule of alpine, rock, ski, and ice guiding, client care is of utmost importance. Our guides are fun, intelligent, worldly, educated, certified, and they provide an unsurpassed level of attention to their clients.


Summit day is a long day, often only requiring crampons, a helmet, and a trekking pole, though you will have an ice axe and harness, and your guides will have ropes in case the conditions require such equipment. After your summit day, you will descend to basecamp and further to the trailhead over a few days. If the weather cooperated and there were no storms to wait out, you may arrive early to Mendoza, where you will have the options of visiting hot springs, joining a wine tour, and exploring the downtown area with nightly outdoor performances in the many city parks.

Course Details


The Aconcagua Expedition is a mostly-inclusive trip starting in the wine capital of South America - Mendoza, Argentina. After a gear check and acquisition of climbing permits, the team will travel 3 hours to your hotel in Los Penitentes (8,500’/2600m). From there, a short drive takes you to the trail head. After three days of hiking with light packs (mules carry most of the weight), you arrive at basecamp Plaza de Mulas (14,400’/4400m), where you will spend three nights for acclimatization. After a rest, the team begins its ascent of the mountain utilizing 2-3 camps, depending on the team’s needs and the weather. Porters are available to carry your personal equipment to the higher camps and back down. Team members often chip in for a porter together.

Lead Guide: Mike Lewis, AMGA Certified Rock and Alpine Guide


Climbers joining this expedition should have taken a 5-day Mountaineering Course with CMS or an approved comparable course with another company, or have ample personal experience camping, using crampons, ice axe, and climbing peaks. Prior experience above 15,000’ on such trips as the Mexico Volcanoes, Ecuador Volcanoes, Mont Blanc, or similar types of expeditions is highly recommended.


Preparation: Expedition members should have good core strength, excellent hiking and cardio-vascular fitness, and the strong mental and physical stamina to move for 12-15 hours in cold weather with short breaks. Training should include many hours each week of hiking with a pack, stairmaster, running, and a daily regimen of core-strengthening exercises such as push-ups, yoga/stretching, cross-fit, etc.
