The Rio Verdão, also known as Rio Verde, is a river flowing through the southern part of the state of Goiás in central Brazil. It is a tributary of the larger Rio dos Bois. The river passes by or through the municipalities of Rio Verde, Santa Helena de Goiás, and Maurilândia, indicating potential access points for paddlers in these general areas. A specific trailhead or access point is documented near the town of Turvelândia, Goiás, where a diving trail follows the river's course. The river's Portuguese name translates to "Big Green River," suggesting a waterway with a notable greenish hue, likely due to its natural setting and vegetation. The region is characterized by the Brazilian Cerrado biome, which implies a landscape of tropical savanna with gallery forests potentially lining the riverbanks. The river is used for diving and exploration, indicating clear water suitable for such activities at certain times. There is no indication of specific paddling restrictions, major hazards like rapids or dams, or developed facilities for boaters along its banks. The overall character appears to be that of a regional river supporting local communities and recreational activities within the Goiás interior.
