International Mountain Guides is the oldest and most respected high-altitude guide service in the world and has been operating successfully since 1975. The partners at IMG, Phil Ershler, Eric Simonson, and George Dunn, have lead and organized hundreds of expeditions worldwide. Each is an AMGA certified alpine guide with Himalayan experience including Mt. Everest, K2, Kanchenjunga, Shishapangma, and Cho Oyu. IMG's Aconcagua programs are organized and directed by Phil Ershler. Phil has led and organized literally hundreds of international expeditions including dozens to Aconcagua.
In choosing International Mountain Guides for your Aconcagua climb, you are choosing the highest quality expedition, the most capable and qualified guides, and a highly personalized guide service that strives to limit risk and maximize success as our two main priorities. Of course, we'll have some fun, too!
International Mountain Guides has been guiding on Aconcagua continuously for longer than any other guide service. In fact, we were one of the first companies to pioneer the Relinchos Valley route more than thirty years ago when there was almost no one on Aconcagua. We also had some of the first guides in the Guanacos Valley.
Over the course of almost 40 years IMG has had one of the highest, if not the highest success rates for reaching the top. The reason our success rate is so high is not an accident. We intentionally do not run dozens of Aconcagua expeditions a year, nor do we run hundreds of clients through our program. We focus on a personalized, professional experience. We want to build a relationship with our clients and give them the best possible service, with the highest chance of success. Also, our guides simply love to summit! There IS a difference between our expeditions and those of other guide services.
We have an impeccable record of client care and an unmatched success rate due to the expertise and professionalism of our IMG leadership and guides. We feel that our guides are an integral part of our program and help to create an unforgettable experience for you. Thus, IMG employs only world-class guides who adhere to strict American and International guiding standards. IMG is an American Mountain Guides Association (AMGA) accredited guide service.
