Fishing near Beltrán, Santiago del Estero

Beltrán sits in Santiago del Estero province, in the semiarid Chaco lowlands of northern Argentina. The area's fishing revolves around the Río Dulce, which runs close to the city, and the broader network of rivers and lagunas that cross the province — including the Río Salado and smaller waterways such as the Río Namby. These warm, slow-moving waters are typical of the Chaco plain and draw local anglers year-round.
