White sand dunes dotted with seasonal rainwater lagoons in Maranhão, Brazil.
Lençóis Maranhenses is the largest dune field in South America, uniquely characterized by thousands of seasonal, crystal-clear rainwater lagoons that emerge between white sand dunes.
Do not expect to find the exact same lagoons seen in previous years; due to shifting dunes and varying rainfall, the landscape is dynamic and the lagoons change shape and location annually.
Imagine standing amidst a vast, blindingly white expanse of sand, only to discover hidden, turquoise pools of warm rainwater nestled in the valleys. At JAFFA, we don't just discover exceptional places; we study their nuances to help you craft an experience worthy of you. Here, you can swim in pristine pools, traverse the shifting dunes, and witness sunsets that paint the landscape in surreal hues, far removed from the ordinary.
Access is primarily via the gateway towns of Barreirinhas or Santo Amaro. The nearest major airport is in São Luís, followed by a 4-5 hour drive. Within the park, travel is restricted to authorized 4x4 vehicles or guided trekking.
Moderate to high; trekking across dunes requires good physical fitness and endurance against heat and sandy terrain.
3 to 4 days is recommended to explore the main lagoons and surrounding coastal villages.
June through September, when the lagoons are at their peak volume following the rainy season.
The park is open to visitors, but access to the dunes requires coordination with authorized local guides.
Suitable for adventurous families, though the off-road travel and heat may be challenging for young children.
Private vehicles are prohibited within the dunes; all excursions must be conducted with guides accredited by ICMBio.
