We did the 7 day trekking through Choquequirao ending in Aguas Calientes. That is an awesome trek, the camping very comfortable, the food excellent and the guide and staff are wonderful people. Dany is more than a guide, is a friend that really loves his land and what he does, he loves teaching you on the road everything about the Incas, the faith, the tradition and even culinary secrets.
You leave all the stress in those amazing mountains, though you have to be in good shape to enjoy it.
