The trip was well organized and a lot of fun. The food was delicious. The physical work was worthwhile and rewarding.
The Inca Trail is by far the best way to see Machu Picchu. The porters were all respectful and professional. The views were gorgeous. I would do another trek with Inca Trail Reservations .
The hiking was a lot of work with many up hill and down hill parts that were especially difficult at the high altitide, but acclimating early in Cusco was a good idea. The Sacred Valley tour was okay but no where near as good as the Inca Trail.
