First of all: before I came to do the Inca Trail , people told me that it is not something for lazy people. And that is true: it's not the easiest thing. But one of the most beautiful. We had 4 days of beautiful nature, the team was great and we had an amazing time.
Even if the weather was not always the best, it couldn't mess up the mood of anyone and we had a great great time. I can only recommend the Inca Trail to anybody, and with enough will it is possible for everybody. If you don't like rain though, make sure to not go in the beginning of the year !
