Laguna de los Porongos lies approximately 380 kilometers southeast of the city of Santiago del Estero, within Departamento Rivadavia, near the borders of Departamentos Quebracho and Mitre. It sits close to the provincial boundary with Santa Fe, and the nearest settlement is Colonia Mac Kinlay, roughly 60 kilometers from Selva, the departmental capital. The laguna has been declared a protected natural area by provincial authorities.

The water body is part of the Bañados del Río Dulce wetland system, a vast lowland environment where open water, reed beds, and flooded grasslands merge across the flat landscape. The surface is generally calm and reflective, with juncos (rushes) lining the shallows and wide skies overhead. Approaching and entering the water requires navigating thick, deep mud along the margins, which can be physically demanding and should be factored into any access plan.

Wildlife is a primary draw. The laguna supports notable populations of pink flamingos, teros, gallaretas, and suris (rheas), making it a recognized destination along ornithological routes. Migratory birds also use the wetland, adding seasonal variety to sightings. Fishing for tarariras and doradillos is practiced in the area.

The combination of remote location, muddy access, and wetland terrain means paddlers should be self-sufficient. No facilities or amenities for paddlers exist at the site. Road access to the area is poor and unreliable, which has practical implications for reaching the put-in with boats and gear.
