The Alter do Chão region in Pará, Brazil, is characterized by its unique river landscapes and seasonal transformations. The area features a distinct natural phenomenon near Santarém where the Tapajós and Amazon rivers run side by side for roughly eight kilometers without mixing, due to differences in sediment, density, temperature, and velocity.

The landscape shifts significantly based on water levels. During the dry season from August to December, low water levels reveal fine white sand beaches along the Tapajós River, which are accessible via boat tours to locations such as Cajutuba, São Domingos, and Pindobal beaches. Conversely, the rainy season from January to July brings high water levels that allow for navigation through flooded forests.

Recognized by The Guardian as a premier destination, the region offers both natural scenery and local cultural experiences, such as Carimbó music.
