Machu Picchu, the lost city of the Incas, is actually a royal retreat and sacred center that was built by the great Inca ruler Pachacuti. Apart from Quechuas,the indigenous people living there, nobody knew of Machu Picchu's existence until American historian Hiram Bingham discovered it in 1911. As ther are no roads leading to the site, the only way to get here from Cusco is by the Peru Rail. You can check them out at

Of course, the rail prices are about one third more for foreigners, even in the "backpacker" train, but the fancy tourist train is not really worth the price, as it is not that much different from the backpacker train and the journey is only about 3-4 hours. Rail workers actually went on strike the day we were supposed to depart. This is a common occurrence, so just don't plan to fly back home on the same day!! Aguas Calientes, also known as Machu Picchu Pueblo, is a small town at the base of Machu Picchu where you will find affordable lodging, restaurants, and souvenirs.
