Do it !

I went on the Inca Trail in the winter 2014 and it was an amazing trip. Four days of hiking and three nights at different campsites. All the campsites had amazing views, but not always amazing sanitary facilities :)

For the trail I booked a porter, which helped me to enjoy the trip in a good way. In total all the porters were very good, they were sweet and the cook made amazing food. I'm not sure I have ever tried so amazing food.

If you're thinking about doing the Inca Trail, I would say yes, dot it. It is a memorable experience and you get to see so beautiful nature and of course Machu Picchu.
