Guides

We strive to employ the finest guides in the industry; our guide team is made of highly skilled instructors, experts on Aconcagua, and leaders and decision makers in the complex world of mountaineering. We create an environment where our guides excel, climbers are well prepared for success, and we remain environmentally sensitive with a keen eye on managing risks.

Our guides leadership skills were excellent, best displayed by their patience, careful consideration, and communication of our summit plan considering adverse weather conditions. Both guides not only looked after our own safety, displaying experienced and deep knowledge, but also help others on the mountain where they could. -2024 Climber
