Inca Trail Biodiversity: Wildlife and Flora of Machu Picchu

A Unique Biological Corridor in the Andes

The Inca Trail to Machu Picchu is famous for its breathtaking landscapes and archaeological sites, but it is also one of Peru’s most important biological corridors. As hikers follow ancient pathways built by the Incas, they pass through diverse ecosystems that support an extraordinary variety of plant and animal life.

The route lies within the Historic Sanctuary of Machupicchu, a protected area established in 1981 and recognized by UNESCO as both a Natural and Cultural World Heritage Site.

The Historic Sanctuary of Machupicchu protects an impressive diversity of species.

Recorded Fauna

• 87 mammal species
• 447 bird species
• 17 amphibian species
• 22 reptile species
• 13 fish species
