Climber Experiences

Gabriel and Mariana were really fantastic and helpful, especially since I struggled with acclimatization. Suzanne (at base camp) was also really great. When I descended early she looked after me to ensure that all of my logistics for leaving the park were coordinated. The trip was overall well organized, very informative, very realistic expectations and a great experience – unfortunately, my body did not hold up as well as usual, but I do not feel that I (or the company) could have done anything differently to improve my chances. A great climbing team!

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.

Lieber Joaquin,
Als erstes möchte ich mich bei Dir für Deine Leistungen bei der Expedition zum Aconcagua bedanken. Bergführer Abi Kirschner hat sich sehr lobend über Deine Arbeit geäußert. Auch Pierre Kintgen war mit Bergführer und KL Adventure sehr, sehr zufrieden. Ich denke, das wird unseren gemeinsamen Produkten sehr gut tun – denn die Teilnehmer tragen Ihre Zufriedenheit weiter und das ist die beste Werbung für uns alle. Ich danke Dir und Deinem Team für die hervorragende Arbeit und Bemühungen! Herzliche Grüße aus München.

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.

Lieber Joaquin,
Ich möchte Dir nochmals herzlich danken für Dein großes Engagement, für die perfekte Organisation und all die vielen Kleinigkeiten, die Du für uns so selbstverständlich erledigt oder geregelt hast. Vielen Dank für die ausführliche e-Mail-Kommunikation und Beratung vor unserer Expedition, für Deine engagierten und motivierten Mitarbeiter im Base-Camp, in Mendoza oder wo sie uns auch immer geholfen haben, für die Auswahl von Rob als Guide und für die exzellente kulinarische Verpflegung. Richte bitte besondere Grüsse an Jorgelina und Juan aus, die uns so erstklassig verpflegt haben. In meinem Kopf habe ich unzählige wunderschöne Bilder und Erinnerungen an diese Expedition, die man nicht mit dem Fotoapparat festhalten kann, die mich aber sicher mein Leben lang begleiten werden. Danke!
Herzliche Grüße,

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.

Hi Joaquin, I was a member of your January expedition to Aconcagua, I was very impressed with the entire setup and I would like to compliment you on how smoothly the expedition went. I was very impressed with the skills of both Gabriel and Mariana and if it hadn’t been for them and the decisions they made I am quite sure we would not have made the summit.

Hey Joaquin
We have used Aconcagua Express services every year we have guided Aconcagua and we have been 100% satisfied. Aconcagua Express is exceedingly professional, on time, and a good value. We would not choose another service for our expeditions.
