Machu Picchu Tours and Tickets

The lost city of Machu Picchu is the most famous archaeological site in Peru and, arguably, all of South America. The UNESCO World Heritage–listed collection of temples, terraced hills, and plazas was once the mountaintop citadel of the ancient Inca empire. It may now be world famous, but Machu Picchu still hasn't revealed the mysteries behind its construction, function, and eventual demise.
