The Río Corrientes runs approximately 200 kilometers through the province of Corrientes, Argentina, originating at Laguna de Iberá and flowing southwest to its confluence with the Río Paraná at the town of Esquina. The full length of the river has been paddled by kayak, with at least one multi-day traverse completed in six days.

The lower 30 kilometers approaching Esquina present the most demanding section of the route. Here the river broadens considerably and divides into multiple channels separated by islands of camalotes — dense mats of floating aquatic vegetation. Current strength diminishes significantly in this stretch, and identifying the main navigable channel is genuinely difficult; paddlers have reported having to backtrack after following dead-end branches. This section demands patience and good route-finding judgment.

Heat is a serious consideration on this river. Paddlers on a multi-day traverse experienced oppressive conditions, requiring frequent improvised cooling measures throughout the day. Severe thunderstorms are also a real hazard; one traverse encountered three intense storms over six days. These conditions make heat management and weather awareness essential safety factors for any multi-day trip.

The full river traverse from Laguna de Iberá to Esquina is a logical through-paddle, and it is possible to continue onward down the Río Paraná from Esquina for paddlers seeking a longer expedition.
