Brazil is known for its diverse landscapes, from lush rainforests to stunning beaches. However, one of its most unique natural wonders is the surreal landscape of flooded sand dunes, filled with turquoise waters. These dunes are a key feature of Lençóis Maranhenses National Park, located in the northeastern state of Maranhão. But what exactly are these, and why are they so special?
Lençóis Maranhenses National Park is a breathtaking landscape that stretches over 155,000 hectares, featuring vast white sand dunes and crystal-clear freshwater lagoons. The name “Lençóis Maranhenses” translates to “Maranhenses bedsheets,” a fitting description of the park’s expansive, sheet-like sand dunes. These dunes extend up to 50 kilometers inland from the coast, reaching heights up to 40 meters.
So, what causes the formation of these flooded sand dunes in Brazil? The process is fascinating and tied to the region’s seasonal rainfall. From January to June, the rainy season in Maranhão, rainwater fills the valleys between the dunes, creating stunning freshwater lagoons. These lagoons can be up to 300 meters long and 10 meters deep, with water so clear it resembles turquoise jewels scattered across the white sands.
The underlying impermeable rock layer prevents the water from draining away, ensuring that the lagoons remain until the dry season. When the dry season arrives (from July to December), the scorching sun evaporates the water, leaving behind a stark desert landscape until the next rainy season.
Lençóis Maranhenses National Park offers a range of activities for adventurous travelers. Swimming in the lagoons, hiking across the dunes, and sandboarding are popular pursuits. The park is also a haven for wildlife enthusiasts, home to a variety of species, including monkeys, sloths, armadillos, and numerous bird species like parrots, toucans, and macaws.
The nearest airport to Lençóis Maranhenses National Park is Jericoacoara Airport, approximately 200 kilometers away. Accommodation options include hotels and pousadas in Barreirinhas and Atins, or for those seeking a more immersive experience, camping within the park is an option.
To experience the flooded sand dunes at their best, plan your visit during the rainy season (January to June) when the lagoons are full. However, the park’s unique beauty can be appreciated year-round.
The flooded sand dunes in Brazil, located in Lençóis Maranhenses National Park, are a natural wonder worth exploring. Their seasonal transformation from a desert landscape to a lagoon-filled paradise is a sight to behold, offering a unique blend of desert and aquatic landscapes that will leave you in awe.
