it was a nice and interesting track, we enjoyed every moment of it. The food is amazing, better compared to home. The porters are nice and strong. The guides knowledge about the Inca Trail is very impressive.
The first day is a good warming up, it is an easy day compared to the 2nd day. the 2nd day is short but hard, after you reach the top, you will feel amazing. The 3rd day is long but so beautiful and the last day is a short day but a lot explanation about machu pichu.
to summarize: fabulous view , very good food , nice people, money well spend.
