Rio dos Couros flows through one of Brazil's most spectacular highland landscapes, draining the southern portion of the Chapada dos Veadeiros in Goiás state. This river is a tributary of the upper rio Tocantins basin, coursing through a region renowned for dramatic waterfalls, crystal-clear waters, and extraordinary biodiversity. The surrounding terrain is characterized by the ancient quartzite formations of the Chapada dos Veadeiros plateau, and the river's course is punctuated by cascades and natural pools that define both the scenery and the fishing experience. The area sits within and adjacent to the Chapada dos Veadeiros National Park, one of Brazil's most celebrated protected areas, making Rio dos Couros a destination where natural beauty and ecological significance go hand in hand.
