Rio San Jose is a stream flowing through the Arica y Parinacota Region of northern Chile, one of the more notable freshwater fishing destinations in this arid corner of the country. The river stands out as one of the top fishing waters in the region, drawing anglers to its banks amid the dramatic high-desert and Andean landscape characteristic of far northern Chile. Its position in Arica y Parinacota places it in a geographically unique setting, where the Atacama Desert meets the foothills and altiplano of the Andes, creating a distinctive riparian corridor in an otherwise dry environment.
