The Lençóis Maranhenses National Park, located in the state of Maranhão, is one of the most surreal landscapes in Brazil—and possibly the world. Here, endless white sand dunes stretch across the horizon, interrupted only by crystal-clear freshwater lagoons that appear during the rainy season.
Often called a “desert with water”, this natural wonder is a dream destination for photographers, nature lovers, and travelers seeking unique and otherworldly scenery.
What Makes Lençóis Maranhenses So Unique?
Despite its desert-like appearance, Lençóis Maranhenses receives significant rainfall from January to June. The result? Between May and September, the dunes fill with hundreds of turquoise lagoons, creating a natural spectacle that’s unlike anything else on Earth.
Key features:
- Sand dunes up to 40 meters high
- Seasonal lagoons perfect for swimming
- Sunset views that reflect light off the water and sand
- A feeling of isolation and awe-inspiring scale
Where Is Lençóis Maranhenses?
The park is located in northeastern Brazil, near the Atlantic coast of Maranhão. The main access towns are:
- Barreirinhas – The most popular base for tours and accommodations
- Santo Amaro do Maranhão – Quieter, with more direct dune access
- Atins – A remote fishing village at the edge of the park, ideal for kitesurfing and rustic stays
How to Get There
Step 1: Fly into São Luís (SLZ)
The capital of Maranhão, with daily flights from major Brazilian cities.
Step 2: Travel to your base town
- To Barreirinhas: ~4 hours by van or 4×4 transfer
- To Santo Amaro: ~5 hours with part of the trip on sand tracks
- To Atins: Travel through Barreirinhas + boat or 4×4 combo
