Comments: To finish this tour the professor-photographer, who was not wearing hiking shoes, is going to descend from his observation perch, cross the parade field, walk between the buildings in the sacred site, which we saw before (<= Machu Picchu #14 and <= Machu Picchu #15), and begin the ascent of Huayna Picchu, the base of which you see in the background in this photo.
