Linking discussions about mountain and territory concepts, this paper analyzes the role of mobility in the production of pewenche territories throughout footprints and trails used by the Pewenche communities of Cauñicú and El Barco in Alto Biobío, Wallmapu, Mapuche territory. Based on a comparative study supported on qualitative methods, the main practices associated with mobility that explain each community's territorial dynamics will be described. It is concluded that the trail (ptrarüpü) articulates the Pewenche mountain by transhumance practice. At the same time, it reveals the transformations and dynamics of Pewenche territory, bringing with it the emergence of new mobilities.
