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,

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.

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.

Dear Joaquin,
Thank you for everything and making our trip to Aconcagua 100% successful! The entire team reached the summit via the False Polish route the 12th of February. Your services and staff helped make the expedition a better experience for our team. Carolina and Marcelo were great!

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.

Let me just say thank you for how you were with my wife while I was on the mountain. This was a very important to me and I am very pleased that you were so helpful with letting my wife know what was going on.
Leo was a fantastic guide with great energy, and I could not ask for a better companion for the duration of the trip!! All in all, the trip was fantastic and well organized!!
Anyhow, thanks again for all your hospitality and helpfullness…you guys should be proud of your business!

The two guides were excellent in every possible respect. Everything was well prepared and well organized. Overall I am very much impressed by the dignity, the professionalism and the good manners of the guides. Organization and set up of the expedition was at a very high level.

I will certainly recommend your agency to other fellow climber how will want to try the same experience. Thank you

Everything went very smooth, it was great to have a small bag of stuff sent from Plaza Argentina around to Plaza de Mulas, as we could have clean underwear, socks and our trail shoes without having to carry them to high camp.

Tatiana seemed very knowledgeable with first aid and altitude sickness, and seemed well prepared.  Tatiana’s food was awesome. The other groups in our camps were jealous when all they had was rice and we had fresh baked pizza in Camp 2! A couple mornings in base camp, there was not much provided for breakfast (one day was only toast) and we finally had to ask them each day to make eggs.

Joaquin was very helpful with all of my requests, and very quick to respond, which is one of the main reasons I selected KL Adventure to work with on this trip.

The transfers and transport was fine.  All vehicles were comfortable and there was plenty of room.  Hyatt is awesome of course. Penitentes is not great, but obviously there is no other option.

The trip was great, we will definitely work with you again for our 2010 climb, and also hope to add a Patagonia trip in the near future. It was also nice to have Joaquin meet the group in Mendoza and to spend more time with him on the drive to Santiago. We would definitely want to have Tatiana as our guide again.  She was exceptional and there was not another guide on the mountain I would have rather had than her. It is also very nice to have a local guide as your leader, better in my opinion than having American or European guides.

Billi also did a very nice job, as an assistant guide she was great.  The two of them worked very well together.
