It is located in the upper zone of the Vilcabamba Mountain Chain, between the Río Tambo district, province of Satipo (Junín region) and the Echarate district, province of La Convención (Cusco region), covering an area of 305,973.05 hectares.This territory is mainly mountainuous, with virgin woods and abundant biological diversity. Therefore, its protection is priority to guarantee the stability and integrity of the soils and water of the Ene, Tambo and Urubamba river basins.This region is inhabited by some native communities that belong to the Arahuac family, mostly to the Asháninka and Machiguenga ethnic groups; however, there are also some inhabitants of the Yines and Caquintes ethnic groups. All of them are committed themselves to the sustainable use of natural resources.
The Otishi National Park has a large biological diversity and is connected to other important biological areas as part of the Vilcabamba-Amboró Binational Corridor. It provides important living zones, evidence of endemic species and a great diversity of ecosystems. The fauna is quite diverse as it is home to a large quantity of bird species, small and big mammals, amphibians, insects, butterflies, etc. They live in a zone of vegetation made up of tropical pastures, locally known as pajonales, queñual forests (Polylepis spp.), and mixed low forests of small trees.
In this complex ecosystem the 'Pavirontsi' stands out as the largest natural bridge in the world. When this bridge is crossed by the Cutiviren river, it forms a huge tunnel over 219.82 feet high, 721.78 feet long, and with an opening of around 206.69 feet wide.
