I found the whole experience incredible. Our Guide was friendly and very knowledgable. He gave us plenty of information along the whole four days as well as a fantastic tour of Machu Picchu itself.
The porters did a fantastic Job all along the way, carrying all the equipment, as well as put thing up tents and cooking all the food. Speaking of which, the meals were delicious as well as substantial for long days of trekking.
The Inca Trail is definitely something i would do again and recomend to anyone to do. The Trek can be a bit tough but the Inca sites along the way as well as Machu Picchu is well worth the effort.
