Lençóis Maranhenses National Park is comprised of vast areas of dunes and crystal-clear lagoons, as well as other ecosystems such as the ocean coast and sandbanks. The landscape is marked by the unique interaction of wind and sand that form the dunes, and the depressions between them fill with water during the rainy season, creating a surreal and unique landscape.

Main elements that make up the park:

Dunes and Lagoons: These are the most characteristic elements, with the white sand dunes and interdune lagoons that form throughout the year.

Ocean Coasts and Sandbanks: The area also includes coastal and sandbank ecosystems, which form part of the transition zone between different biomes.

Mangroves: Another ecosystem present in the region, contributing to biodiversity.

The park is located on the eastern coast of the state of Maranhão and is internationally recognized as a UNESCO World Heritage Site.
