Fishing near Malargüe, Mendoza

Malargüe sits in the far south of Mendoza province, deep in Patagonian Andean country, and the fishing here is defined by cold, clear mountain rivers and streams running through high-desert and volcanic terrain. The Río Malargüe and Río Atuel are the marquee local waters, known for rainbow trout and brown trout, while the broader Malargüe department encompasses several river basins — Atuel, Salado, Malargüe, and Grande — each with its own network of fishable channels and tributaries.
