Arroyo Carambola is a stream winding through the heart of the Iberá wetlands in Corrientes Province, Argentina, serving as one of the defining waterways of the Carambola Gateway within Parque Iberá. The stream flows through a landscape of extraordinary ecological richness, passing through forested islets, floating islands, and expansive wetland habitat before widening into the Paraná lagoon to the west. The western sector of the Iberá system — which includes Arroyo Carambola — drains toward the Corrientes River and is characterized by notably clear, crystalline waters that set it apart from other parts of the reserve. This clarity makes it particularly well-suited to fly fishing, where presentation and stealth are rewarded. The stream corridor is lined with gallery forest and riparian woodland, with forested islets providing shaded banks and complex structure throughout its length.
