Amazonas, Anavilhanas National Park
When you go into the Anavilhanas National Park, we pass countless tiny islands and mangroves, where white-sand beaches emerge during the dry season. At this point, the Rio Negro reaches 27 km across and looks almost like an open sea. Nearly 400 islands are scattered along 90 km, forming the world’s largest freshwater archipelago. The flow is immense, and take note: the river is around 300 metres deep!
