Experience a beautiful river tour along two of the Amazon's biggest rivers. See the Rio Negro, the black river that surrounds Manaus, and the Solimões River, a brown stretch of the Amazon River in Brazil.

It keeps the name Solimões until it meets the Rio Negro; after the rivers merge, the Amazon flows toward the Atlantic Ocean.

Observe the striking difference between the two rivers at this unique sight near Manaus.

Try to catch the pirarucu (Arapaima gigas), the world's largest freshwater fish.

During the river's flood season, usually between March and the beginning of September, visit a floating village on a tributary of the Rio Negro. Learn about the community's distinctive way of life in floating houses.
