Río Perico is a freshwater river flowing through Jujuy Province in northwestern Argentina, passing near the city of Palpalá and the broader San Pedro de Jujuy area. The river is part of the rich hydrological network of the Jujuy region, draining from the Andean foothills and flowing through a landscape shaped by the dramatic elevation changes characteristic of northwestern Argentina. The surrounding terrain reflects the transition between the high Andean puna and the subtropical lowlands, giving the river a dynamic character that changes with the seasons and with elevation along its course.
