Climber Experiences

Le voyage était parfait, avec l’immense satisfaction d’avoir été en haut de l’aconcagua !
Excellent guides, very professional and very dedicated to the success of the expedition. Very good logistics (transfers, mules); Pre-Read materials (Aconcagua book, map…) were very good; Excellent hotel in Mendoza (Hyatt!)

I would definitely recommend KL Expeditions / Aconcagua Express Expeditions.

Hallo Joaquin,
Nun bin ich schon einen Monat zurück in Deutschland und denke immernoch jeden Tag an die tolle Bergtour zum Aconcagua. Du glaubst nicht wie glücklich ich bin, daß ich das geschaft habe. Dies habe ich im besonderen Dir und Deinem Unternehmen Aconcagua Express zu verdanken. Mit Tom Torkelson hatten wir einen super Bergführer der zum einen eine sehr schöne Route zum Gipfel geführt hat, Vacas Route, die zum anderen auch eine optimale Aklimatisation ermöglicht hat. Die gesamte Organisation war vom Anfang bis zum Ende sehr gut. Es gibt wirklich nichts was ich meine, was besser gemacht werden könnte. Wenn Du neue Kunden aus Deutschland oder Europa hast, die Fragen zur Aconcaguabesteigung haben, kannst Du Ihnen gerne meine email-Adresse geben, damit Sie Kontakt mit mir aufnehmen können.
Vielen vielen Dank!!

The memories I have of our trekking on Aconcagua is one of my fondest. It was a most fantastic experience…. one which I will treasure for the rest of my life. Thank you and your team members for making it possible. I very much enjoyed the personal one-on-one relationships we developed with you and your team. Your professionalism and desire to please the customer is very evident and commendable.

Aconcagua Express & KL Adventure was truly a wonderful experience. From the pre- trip client care to the world class guide and staff, fabulous base camp cuisine, traveling safely and ethically, superior route experience and better pricing than most other outfits. Truly a fantastic trip that I have no reservations in recommending to Americans or anyone else interested in a climb.

Hello, Magaly!
Was good talking to you on the phone today. We are very happy with the trip, a bit tired and feel very lucky with the weather and our guide, Gabriel, both being important factors that allowed us to summit.

Beautiful route, and the strategy for adjusting to the altitude was very good. I really enjoyed our team, and Christina and Marianna also seemed to be enjoying themselves very well. Good atmosphere.

Choice for Aconcagua Express Expeditions was also because you were the only ones to actually give me advice on an expedition when I e-mailed you. You offered me a specific expedition and date. So the personal info was important for me.
