The Rio Crixás-Açu is a significant river in the state of Goiás, central Brazil, flowing for approximately 400 kilometers through the Cerrado savanna region. It serves as a tributary to the larger Araguaia River, with a notable multi-day paddling route beginning at the Rio Pintado bridge and concluding in the village of Luiz Alves on the Araguaia. This journey connects the Pintado, Crixás-Açu, and Araguaia rivers, indicating a route suitable for extended canoe or motorboat trips through varied river landscapes. The river is characterized by its role in supporting local fishing activities and is known for species such as Redtail catfish, Piraíba, and Barred sorubim. The surrounding Cerrado ecosystem contributes to the river's setting. The river also holds ecological significance as a release site for hatchlings of the giant South American river turtle (Podocnemis expansa), with tens of millions released into its waters, highlighting an important wildlife feature for paddlers to be aware of and respect. There is no information indicating that paddling is prohibited, but the presence of conservation efforts for turtle species suggests paddlers should exercise caution and avoid disturbing sensitive habitats. Information regarding specific access points, seasonal water levels, water temperature, water quality, facilities, or hazards is not available.
