The whole archaeological complex covers approximately 5 square kms. As it is situated in the high jungle, its climate is semi-tropical, warm and humid. It is open every day from 8.00 am to 5.00 pm. The archaeological Complex of Machu Picchu was revealed to the world in July 1911 by Hiram Bingham professor at Yale University, U.S.A. Considered as one of the most famous archaeological sites in the world, it all makes up a complex of constructions located at different points of the Vilcanota cordillera, unique for their network of pathways or roads traditionally known as the Inca Highway.
Access is by a narrow, steep path.
The traveler who has more time to spare may stay overnight at the Machu Picchu Sanctuary Hotel. Machu Picchu is also one of the Inca's best kept secrets, since they did not left written records and Spanish chronicles make no mention of the citadel, it remains a mystery. The present entrance on the southeastern side leads to the agricultural section. The agricultural area consists of a series of terraces and irrigation channels that serve dual purpose, as cultivation platforms making it self sustained, and as retention walls to avoid erosion. Some smaller buildings next to large terraces are part of this section and thought to have served as lookout posts.
