The Rio das Barreiras is a coastal river system in the state of Alagoas, Brazil, flowing through the municipality of Coruripe before reaching the Atlantic Ocean. The river is characterized by its connection to both freshwater and estuarine environments, with its lower reaches forming a lagoon or pond that separates the river mouth from Barreiras Beach. This creates a dynamic fishing area where anglers can target a mix of species influenced by both riverine and marine conditions. The surrounding area is known for its small fishing villages and offers a more authentic experience away from major tourist routes.
