Delta do Parnaíba Essentials

The Delta do Parnaíba is the only open-sea delta in the Americas, comprising over 70 islands where the Parnaíba River meets the Atlantic. This list covers the essential transit hubs like Tatus port, the world's largest cashew tree in Cajueiro da Praia, and the unique 'sleeping tree' shaped by coastal winds. From the granite formations of Pedra do Sal to the sandbanks of Macapá, these sites represent the diverse ecological landscape of Piauí and Maranhão.
