From Machu Picchu we stayed back at Ou Xutai, a town of the same beautiful holy valley as the name, and is the starting and stopping station for most trains to and from Machu Picchu. The scale of the site here is also quite large. Listening to the legend of the Inca warrior Europa Taiwan, the children are very energetic in climbing the mountain, and they don't think it is also a place of 3,000 meters above sea level.
