El Sira Communal Reserve is located in the east-central area of Peru, part of the Eastern Cordillera of the Andes, within the sub-Andean belt; between latitudes 09º 03' and 10º 22' and longitudes 74º 05' and 74º 48'.

The SCR presents an altitudinal gradient from 130 to 2250 meters above sea level and is influenced by the basins of the Ucayali, Pachitea and Pichis rivers.

On the western flank of the mountain range there are phenomena that favor greater condensation of cloud bodies, unlike the east side (Ucayali basin).

The Ucayali River, originating in the Peruvian Andes, borders the eastern part of the El Sira mountain range, with a south - north route.

In its south - north route it borders the western part of the northern sector of the El Sira mountain range.

The Pichis River, born in the Peruvian Andes, borders the western part of the center - south sector of the Cordillera El Sira with a south-north route.
