Ollantaytambo, located at 2792 meters (9160 feet), lies in the picturesque Sacred Valley on the Patacancha river near the town of Urubamba, in between the capital city of the Incas - Cuzco and the Machu Picchu ruins. It's not as well known as the spectacular ancient city of Machu Picchu, but nonetheless worth visiting for those who want to learn more about the Inca Empire. The ruins, perched atop of nearby hills, give silent testimony of once advanced and highly organized civilization. Ollantaytambo is usually a stop for all tourists who come to see Machu Picchu, you should reserve at least one day for visiting, either on the way to Machu Picchu or while coming back to Cuzco.
