I'm one of those customers who when I find the right brand/company/product, it will take something very wrong for me to look elsewhere. I don't like to shop around, and I typically remain loyal. I've been climbing with CTSS for over 3 years, and I've never had a bad experience…

I just came back from this climb with CTSS and had a BLAST. We had an exceptional guiding team: Robert, Ty, Leo, Maxy, and of course Maca, the strongest female guide I've ever met! I felt safe the entire time, learned a lot, and most importantly, had so much fun! Our group…

Climbing the Seven Summits is without a doubt the best company in the industry. I just completed my 6th trip with them to the summit of Aconcagua. They have a commitment safety and hiring world class guides, I wouldn't trust any other company. Thank you

Our guides had 35+ years of experience between them. Our lead guide had sumitted Aconcagua 38 times (his 39th time was with us). Everyone on the mountain knew him and he knew everything about the mountain. We never once felt unsafe, underserved or in-the-dark. Highly recommend…

Well organized in all so many details! Going up Aconcagua within 9 days from Mendoza to the summit exposes your body to unparalleled acclimatisation stress. However we were well prepared and received excellent support from our guides and all the supporting staff. So we reached…
