Rio Paquisa is a stream located in the Arica y Parinacota Region of Chile, flowing through one of the most remote and geographically dramatic corners of South America. Situated in the far north of Chile, this waterway exists within a landscape shaped by high-altitude terrain and the arid conditions characteristic of the region. The Arica y Parinacota Region borders Peru to the north and Bolivia to the east, and its river systems are defined by the extreme elevation changes and desert environment of the Atacama and the Andean altiplano. Rio Paquisa represents one of the lesser-known stream fisheries in this part of Chile, offering a genuinely off-the-beaten-path angling experience for those willing to explore its waters.
