More ways to explore the area's outdoor wonders
Late afternoon light slants across the Tapajós, and boats slip away from the Centro de Atendimento ao Turista as the river seems to pull everyone toward the sandbars. On the Alter do Chão Sunset Tour, the water pushes you around bends of white sand and into quiet channels where the forest breathes and birds call you downriver.
