The National Park was recognized as the Heart of the Biosphere Reserve in 1977, and declared Natural Patrimony of Humankind in 1987 by the UNESCO. The Manu National Park extends over 1 532 806 hectares and represents part of the great biological diversity in the Amazonia. In this region it is possible to observe birds that are difficult to find in other places of the jungle: for example, the harpy eagle (Harpia harpyja), the jabiru stork (Jabiru mycteria) and the roseate spoonbill (Ajaia ajaja). In the riverbanks, on the tree branches, we can find the Muscovy duck or sacha pato (Cairina moschata), wild ancester of the criollo duck. There are also many wild fauna species such as the Orinoco goose (Neochen jubata), the cock-of-the-rock (Rupicola peruviana), the woolly monkey (Lagothrix lagotricha), the black spider monkey (Ateles paniscus), the giant otter or river wolf (Pteronura brasiliensis), the jaguar (Panthera onça), the ocelot (Leopardus pardalis), the spectacled bear (Tremarctos ornatus) and the Peruvian guemal or taruca (Hippocamelus antisensis).
The trip from Cusco to the Manu National Park, along the highway, crosses the Andean crest, where it is possible to admire the sunrise over the jungle from the Tres Cruces viewpoint going down the ecological tiers of the jungle to the Amazonian plain. The Park can be reached through the Manu River; then it is possible to settle at a tourist shelter or to camp on one of the riverbanks. The main activities in this area are the ecotourism and the observation of the amazing flora and fauna, showing an ecosystem that has been evolving without alteration over thousands of years.
