Incredible. The trail is the experience of a lifetime. The guide was extremely knowledgeable about the trail and the history of the Incan culture. The porters always had meals ready when we arrived at the campsite or our lunch area. They even baked us a cake on our third morning ! Seeing Machu Picchu for the first time was amazing and Edwin our guide did an excellent job of explaining the history and meaning of the city.
In terms of organization it was also a great experience. The guides had all of our documents printed and ready when we needed them, from our Inca Trail passes to the train ride home. Overall I would highly recommend the Inca Trail Reservations experience.
