The Inca Trail to Machu Picchu is part of a large and complex network of trails, that the Incas built to connect most the important Inca cities and sites. The Incas constructed nearly 40,000 kilometers (24,850 miles) of cobbled stone paths that stretched the length and depth of the continent. When the Spanish invaded South America over 500 years ago, the Incas destroyed many of the trails to prevent the Spanish discovering their important dwellings.

Today the famous 4 days trek from the trail head at Pisacacucho (KM82) to Machu Picchu is known as the Inca Trail. The Inca Trail offers hikers some of the most extraordinary scenery in the Andes, and is one of the most interesting and rewarding ways to arrive to Machu Picchu. Along the route there are grand and impressionable Inca ruins hidden amongst the thick jungle vegetation,which are often obscured by the constantly moving low lying clouds.
