The Rio Aquidauana is one of the premier sport fishing destinations in Mato Grosso do Sul, Brazil, rising in the Serra de Maracaju and flowing with characteristically fast, energetic waters before eventually draining into the greater Pantanal system. As a key tributary within the Miranda River Basin — a watershed encompassing over 42,000 square kilometers — the Aquidauana winds through a landscape shaped by the Brazilian Cerrado, with riparian corridors of deciduous, semi-deciduous, and gallery forest lining its banks. The river's fast-moving character distinguishes it from the slower, more meandering waterways of the lower Pantanal, creating a dynamic fishing environment with varied structure, strong currents, and exceptional biodiversity. The surrounding region, including the city of Aquidauana itself, is widely recognized as one of the gateway communities to the Pantanal's extraordinary natural wealth.
