Travel Guide to Lençóis Maranhenses National Park
Lençóis Maranhenses National Park, located in Maranhão State along Brazil's northeastern Atlantic coast, is a remarkable natural attraction that spans approximately 1,550 square kilometers. This protected area is characterized by rolling white sand dunes interspersed with thousands of crystal-clear freshwater lagoons, making it one of the world's most unusual ecosystems. Established in 1981, the park showcases a unique landscape that defies traditional desert characteristics.
At first glance, Lençóis Maranhenses may seem like a vast desert; however, it receives over 1,400 millimeters of rainfall annually due to its proximity to the Amazon Basin. This abundant rainfall leads to the formation of temporary lagoons between the dunes, creating a stunning mosaic of white sand and turquoise waters. The lagoons reach their highest levels between July and August, with some becoming up to three meters deep and nearly one kilometer long, offering visitors a striking visual experience.

Travel Guide to Lençóis Maranhenses National Park
The vibrant colors of the lagoons can vary from bright blue to emerald green, depending on sunlight and minerals, making it a photographer's paradise. Swimming in these warm freshwater lagoons is one of the park's most popular activities, providing a refreshing escape in a surreal setting.
Despite the seemingly barren landscape, Lençóis Maranhenses is home to a surprising array of wildlife. During the wet season, fish enter the lagoons through temporary connections with nearby rivers, while some species, like Hoplias malabaricus, have adapted to survive the dry season by burying themselves in the sand until the rains return.
Most visitors begin their journey in the town of Barreirinhas, the main gateway to the national park. From there, certified guides operate 4x4 vehicles that transport visitors across sandy tracks into the protected area. Vehicle access within the park is strictly regulated to preserve its delicate ecosystem, making guided excursions the safest and most practical way to explore the dunes and lagoons.
With consistently warm temperatures throughout the year, Lençóis Maranhenses offers an inviting climate for outdoor activities. The rainy season lasts from February to May, while the lagoons are at their fullest between July and September, making this the ideal time for a visit.
