This is the entrance door to the Sacred Valley of the Incas; the small village of Pisac is located downwards one of the major archaeological sites of the valley. It is suspended on the sidewall of the mountain, bordered by two steep cliffs. This complex, exceptionally well preserved, is made of stairs, terraces, houses, a ceremonial center, etc. The access can be made by taxi, or for the most courageous, by the 4 km of abrupt stairs that climb the 400 m drop, passing through the large terraces of maize cultivation and some watchtowers the Incas probably used to defend the valley. Then, after crossing a tunnel through the rock, we arrive at the heart of the archaeological site; a complex of squared squares surrounding what seems to be a temple, with a sundial (Intihuatana) in the middle. The conservation status is absolutely amazing; walls, doors, windows, they are all in a perfect state. On the other side along the cliff, there are holes in the rock that would be sepultures of numerous noble Incas. This site is uncontestably a must-do in the Sacred Valley, and the walk between terraces, and almost entire edifices will leave an unforgettable memory.
