Also nicknamed the delta of the Americas, the delta of the Parnaíba River is the third largest offshore delta in the world, after those of the Nile and the Mekong. This extraordinary ecosystem is home to dunes, tropical forests, white sandy beaches, swamps, flood plains and mangroves, all of which accessible by pirogues, enabling you to get close up to its rich wildlife. Do not miss the giant dunes of Morro Branco, before a good night's sleep in one of the pousada's on one of the inhabited islands.
