Macchu Pichu is at the lower end of the Sacred Valley, and the only way in and out is walking or catching the local tourist train.
With limited time and tired legs, the train suited us fine and the views of the valley were amazing.
For the most part, the train follows the river Urubamba and the valley gets narrower and narrower.
And in the background the high mountains with the glaciers that store the water for people and crops.
And valley sides terraced by the Incas and still used to provide the food for the inhabitants.
