In the begining i was very nervous if i could get the trip due to hiking in this high, but your guide motívated us a lot. Furthermore we saw awesome nature, Lamas, kolibris and a lot of mountains and glaciers. The service, and special the food was very good and as an vegetarien i got special dishes. The hiking of the different pass es was a challenge but if you take your time it is possible to do it with a normal condition. Overall, I would do the trip totally again and i was a fantastic starter of our South América travel!.
