Accompanied by your guide, today you will venture to climb the 150 steps that separate the summit from the low part of the Ollantaytambo fortress, in which the Temple of the Sun (formed by six huge monoliths of pink granite, with a weight of more than 50 tonnes) and the Terrace of the Ten Niches stand out. The half day excursion ends with a short visit to the Ollantaytambo town, a typical example of the urban planning of the Incas, whose residents still live in accordance with their old traditions.
