Río Correntoso flows through one of Patagonia's most celebrated fly fishing landscapes, serving as a tributary of the legendary Río Simpson in the Aysén Region of General Carlos Ibáñez del Campo, Chile. This river winds through the Reserva Nacional Río Simpson, a protected natural area established to safeguard the region's remarkable vegetation and wildlife following a history of devastating fires and exploitation that had caused widespread erosion, landslides, and flooding. The reserve sits along the corridor connecting the cities of Coyhaique and Puerto Aysén, placing Río Correntoso within one of Chilean Patagonia's most accessible and ecologically significant fishing destinations. As a tributary joining the Río Simpson — ranked among the finest fly fishing rivers in the world — Río Correntoso shares the same pristine Patagonian character that draws anglers from across the globe to this remote corner of South America.
