More ways to explore the area's outdoor wonders
You step onto a narrow speedboat as the river breathes morning cool into your face. The Preguiças cuts a lazy silver path through mangroves and low dunes, the current nudging the bow toward villages that seem to rise out of the water. Capuchin monkeys chatter in the trees like local commentators while the pilot threads channels that tease a different landscape at every bend.
