I really enjoyed walking the Inca Trail . It was the first real trail I ever walked, but it was totally worth it and makes me want to do more trails.
We didn´t really train at forehand, but walking a lot of stairs before you go, definetly helps. The service during the Inca trail is great. Especially the porters are amazing, carrying enormous bags, bringing drinks en the food was delicious. The tents were quite big, you´ll easily fit in there with two persons and the backpacks.
Our guides were Juan Carlos and Sergio and they took good care of us. They have a lot of information about the Inca sights and the English of Juan Carlos is pretty good.
I would advise everyone in good shape to do the Inca Trail if they get the chance!.
