Ascent to the lost Inca citadel in the Andes at Machu Picchu

You climb to the Inca citadel through terraces and stone buildings at 2,430 metres. The mountains, clouds and depth of the valley make it easier to see why the town was built here. A guide explains the stonework, the farming terraces and the buildings aligned with the sun.

4 tour programmes on the site include this stop. The effort level is medium; stepped paths and the altitude can be tiring. In the first days, rest and plenty of water help you adjust. The weather changes fast, so bring a rain jacket, sun protection and non-slip shoes. Entry times may depend on limited capacity.
