Fishing near Libertador General San Martín, Jujuy

Libertador General San Martín sits in the Ramal region of Jujuy province, in the subtropical lowlands at the eastern edge of the Andes foothills. The city is surrounded by a network of rivers and arroyos fed by Andean runoff, with the Río San Lorenzo and Río Ledesma close at hand and the larger Río San Francisco within easy reach. Fishing here centers on these warm-water lowland rivers, a very different scene from the cold trout streams of Patagonia far to the south.
