Riacho Monte Lindo is a stream winding through the Chaco Húmedo region of Formosa Province in northern Argentina, a landscape defined by subtropical wetlands, dense gallery forests, and the rich aquatic ecosystems characteristic of the Gran Chaco. Discovered by Paraguayan explorers around 1918, the riacho became a vital water source that drew settlers to the surrounding area, and today it remains an important natural feature of the Loma Monte Lindo locality. The stream flows through a region of exceptional biodiversity, with riparian vegetation dominated by native species typical of the humid Chaco, providing excellent habitat for a variety of fish species. Camping Río Soñado, situated along Ruta Provincial N° 3 on the banks of the Río Monte Lindo, offers a welcoming base for anglers and outdoor enthusiasts looking to explore this corner of Formosa.
