I have booked "8 Days and 7 Nights Hiking the Inca Trail to Machu Picchu". One of the most important point for me was to have a good group and to enjoy the time together.
During this trip I have found some new friends "Inka Family" from all over the world. We all had a good time during the hike. Our guides "Carlos" and "Marco" gave us good information about the history of the Incas. We did not have the feeling that we have booked a typical organized tour. A big "Thank You" for the porters and the chef! We had good food during these days.
At most I enjoyed the 4 days / 3 nights Inca Trail tour. If you are a social person and you like to meet new people I would recommend this tour.
