Rio Paraguaçu is the largest river entirely within the state of Bahia, Brazil, born in the highlands of the Chapada Diamantina and flowing across the state before emptying into the Baía de Todos os Santos. This is a river of remarkable contrasts — from crystalline mountain streams tumbling through dramatic canyon landscapes to broad, slower reaches and a rich tropical estuary. The upper sections, particularly around Andaraí and Mucugê, are widely regarded among experienced anglers and local fishing guides as offering some of the most spectacular and technically demanding freshwater fishing in all of Brazil. The river's mountain character — clear water, challenging rapids, and deep pools — combined with the stunning scenery of the Chapada Diamantina, makes it a destination unlike any other in the country.
