Lençóis Maranhenses: UNESCO World Heritage Site

The Lençóis Maranhenses are one of those destinations that seem sculpted from a dream. The wind shapes mountains of white sand that embrace crystalline lagoons. Within this ecological paradise in the Brazilian Northeast lies an ecosystem of outstanding universal value.

In this article, you will discover the scientific and aesthetic reasons why the Lençóis Maranhenses National Park has joined the select group of UNESCO World Heritage Sites.

A Rare Geological Phenomenon

UNESCO officially designated the Lençóis Maranhenses National Park as a Natural Heritage Site in July 2024, recognizing its geomorphic and scenic beauty — essentially, the imposing and visually harmonious nature of the region’s landforms.

The identity of Lençóis Maranhenses is molded by a rare geological phenomenon, as it is the largest coastal dune field in Latin America. The freshwater lagoons nestled between the dunes are formed exclusively by rainfall and the variation of the water table, without the presence of drainage channels.

This collection of dunes also boasts a rare configuration, situated in a transition zone between three biomes: the Amazon, the Cerrado, and the Caatinga. For this reason, the park is a sanctuary of biodiversity and a fundamental pillar for the climatic balance of the Americas.

Incomparable Beauty

Can you imagine a landscape in constant transformation? In Lençóis Maranhenses, the dunes can shift between 4 and 25 meters (13 to 82 feet) per year. As a result, lagoons emerge and vanish in different locations, ensuring every traveler enjoys a unique experience when visiting this corner of Brazil.

The desert-like scenery, interspersed with turquoise crystalline lagoons, forms the basis for the “outstanding universal value” criterion, reinforcing its aesthetic importance and a visual contrast that is unique in the world. This mosaic of colors creates a freshwater oasis that leaves every visitor in awe.
