Machupicchu or Machupicchu Pueblo, also known as Aguas Calientes, is a location in Peru situated in the Cusco Region, Urubamba Province. It is the seat of the Machupicchu District. Machupicchu lies at the Vilcanota River. It is the closest access point to the historical site of Machu Picchu which is 6 kilometres (3.7 mi) away or about a 90-minute walk. There are many hotels and restaurants for tourists, as well as natural hot baths which gave the town its colloquial Spanish name. The village of Machupicchu did not exist until the railroad was built, as it was a center for construction workers. It took off after the railroad opened in 1931 and foreign tourists started arriving to visit the Machu Picchu ruins. Enterprising individuals set up businesses serving the tourists, primarily restaurants and small hotels. Those who could afford luxury stayed at the luxury hotel up by the ruins.
