The Inca Trail was a great experience. I highly recommend using a porter for day two though (unless you are Lebrun James). Our guide was really amazing, Raul was really knowledgeable about both the flora and the fauna and the history of the Inca empire.
We saw a lot of ruins, but the best was definitely at the end. Do not forget to bring your camera ! The food was really good, especially considering the conditions. The porters were also really awesome and humble. This was an incredible experience, I will never forget it and neither will the rest of my crew.
