Riacho Monte Lindo Grande is a slow-moving, meandering waterway that originates near the town of Pozo del Tigre in the Departamento Patiño and flows west to east across the province of Formosa, passing through the departments of Patiño, Pirané, and Formosa before emptying into the Río Paraguay near the locality of Dalmacia. The riacho winds through an alluvial plain of variable width, between roughly 800 and 1,600 meters, developing countless meanders, oxbow lakes, abandoned channels, and alluvial levees along its course. During periods of excessive flooding on the Río Pilcomayo, water is channeled into the riacho through a 40-kilometer artificial canal, which can significantly affect water levels.

The paddling character is defined by dense gallery forest and low woodland that press in from both banks, along with palm groves. Submerged root systems and fallen trunks create natural obstacles that require maneuvering, making kayaks and piraguas the craft of choice. The confluence of Riacho Tatú Piré with the Monte Lindo, a spot known locally as "tres bocas," is a notable waypoint and a good location for bank fishing.

A well-documented multi-day route runs from the bridge on Ruta Nacional 11 near Pastoril downstream through Dalmacia and then continues along the Río Paraguay to the city of Formosa, a journey that takes approximately three days. A longer historical route covered the stretch from La Loma (Monseñor D'Andrea) to the city of Formosa over nine days. Since 1990, the Municipalidad de Formosa has organized an annual Travesía Náutica Fundación de Formosa each April, following this same general corridor from the Ruta Nacional 11 bridge downstream.

The surrounding environment supports a wide variety of native wildlife, including numerous bird species — one paddler recorded 19 toucans in a single stretch — as well as the Lechuzón Mocho Grande and other fauna typical of the Gran Chaco. Near the locality of Loma Monte Lindo, the Camping Río Soñado is situated along Ruta Provincial 3 on the banks of the riacho and offers camping, sport fishing, shaded areas, and a swimming pool. The Camping El Recreo de la 87, located between Rutas Provinciales 3 and 14, provides additional facilities with an ecotourism focus.
