The tour lets visitors grasp the magical atmosphere that envelops the Valley as it moves from day to night. First, the still warm light of the setting sun that allows you to admire the temples in relation to the space around them and in their harmonious integration into the landscape. Then, the sunset, in front of the Temple of Concord, which changes the color of the sandstone by changing our aesthetic perception of the monument. Finally, the darkness of the night and the light of the headlights that takes away the surrounding environment and makes them emerge in all their absolute value of universal works, evidence of the ingenuity of our ancient ancestors.
