I consider this trip as one of most beautiful and correct decisions of my life. I recommend it to everyone that wants to live a wonderful history with nature and pure air between inca's constructions and forest.
If you love pre Colombian civilization, so much as I do, I do not have any doubt that you must try it, because Inca Trail is quite beautiful and emotive to people who loves both: nature and inca empire.
I have learned a lot with small communities and people who helped us during this trekking, as porters, guides and everyone else. So nice!.
