It is located in the province of Mariscal Cáceres, San Martín Region. Located on the eastern slope of the tropical Andes of central-northern Peru and with an area of 274,520 hectares, the Abiseo River National Park not only has a magnificent diverse endemic flora and fauna, the same ones that have been maintained and evolved during more than 8 millennia; but it houses threatened species such as the "Mono Choro de Cola Amarilla" in danger of extinction. Under the protection of the National Park there are also archaeological remains, the result of an indigenous and unique cultural development that originates from 6,000 years BC and culminates with the Chachapoya nation, incorporated into the Tahuantinsuyo empire in the s. XV. Its cultural legacy consists of extraordinary archaeological sites that add up to around 36 sites, among which "Los Pinchudos" and "El Gran Pajatén" stand out, both of Chachapoya cultural affiliation, and whose constructions have a unique architectural decoration.
In the province of Mariscal Cáceres, in the department of San Martín.

Finally, in all these places agricultural terraces, irrigation canals, pre-Hispanic roads and places of offerings, outcrops of lithic material used in prehistory and rock art can be seen.
In terms of archaeological heritage, El Gran Pajatén is an impressive monumental complex due to its special architecture. This citadel was built by the Chachapoyas before being subdued by the Incas. Also noteworthy is the funerary complex Los Pinchudos, built on the narrow ledge of a large cliff. His wooden idols, which represent naked beings, were found intact and placed in their original place.
Other remains found include Cerro Central, with around 200 buildings; to the complex of Las Papayas, with about 100 structures, some of carved stone; the archaeological site of Marcial (Pajatén II), also with more than 100 buildings; and many others like La Playa, Apisunchu, Alpamachay and Manachaqui.
The presence of numerous and exceptional archaeological remains within a vast forested area is unique on the continent. This caused UNESCO to declare, in 1992, the Río Abiseo National Park as a Natural and Cultural Heritage of Humanity, a mixed category that the country only shares with the Historic Sanctuary of Machupicchu.
Many are the routes that take you to Machu Picchu, but none is like the Inca Trail Tours, the most famous pedestrian path in the Americas. After flying from the capital of Perú, Lima, you will arrive in Cusco to walk for four days along a path through forests and dense fog, millenary stone steps and discovering the ruins of ancient fortifications and Inca cities, and all the time enjoying majestic views.
