The Rio Areias is a river in the state of Goiás, Brazil, flowing near the Serra dos Pirineus and ultimately joining the Corumbá River. A notable access point for paddlers is the bridge on the BR-060 highway near Alexânia, which serves as a practical launch site. From this bridge, paddlers can embark on journeys upstream, with one documented route covering approximately 12.3 kilometers over a duration of around 4 hours and 18 minutes. This route is characterized by its open-sky path, providing a direct connection to the surrounding landscape. The river itself is classified as a stream, suggesting a more intimate and potentially narrower watercourse compared to larger rivers. The region's climate, with its distinct wet and dry seasons, will significantly influence water levels and flow rates. The waterway is known to support fish species such as Trahira, Spotted pimelodus, and Redbreast tilapia, indicating a healthy aquatic ecosystem. The proximity to the Serra dos Pirineus mountain range suggests scenic, natural surroundings. No specific regulations, hazards, water quality issues, or on-site facilities for paddlers are mentioned.
