Laguna La Blanca is a 700-hectare lagoon located within Parque Nacional Río Pilcomayo in Formosa Province, northern Argentina. The lagoon sits near the town of Laguna Blanca, accessible via Ruta Nacional 86. From the provincial capital of Formosa, travelers can reach the area either via Ruta 11 through Clorinda and then connecting to Ruta 86, or more directly via Ruta 2 to Ruta 86, bypassing Clorinda entirely.

Paddling is an established activity on the lagoon. Piraguas, kayaks, and rabaska canoes are available, accommodating solo paddlers, pairs, and groups. The 700-hectare surface area offers meaningful exploration by water. The region's humid subtropical climate (Cfa classification) shapes both water conditions and the surrounding wetland environment. The lagoon sits within a wetland landscape with native flora and fauna typical of the Formosa litoral.

The sunsets over Laguna La Blanca are among the most notable in the Formosa litoral region. The surrounding environment includes wetlands (esteros) and native vegetation, with wildlife such as woodpeckers documented in nearby trails within the national park area.

Parque Nacional Río Pilcomayo has defined visiting hours — Tuesday hours are 7:00 AM to 3:00 PM — and access to the lagoon and its paddling opportunities may be subject to park operating schedules. Paddlers should confirm current park hours and any entry requirements before visiting.
