Lençóis Maranhenses National Park

Imagine a desert of white sand dunes stretching to the horizon, punctuated by crystalline freshwater lagoons of startling blue and green. That’s Lençóis Maranhenses National Park, a surreal landscape in northeastern Brazil that feels more like a mirage than reality. This otherworldly park is a must for adventurous travellers seeking raw natural beauty, with the best time to visit between June and September when the lagoons are at their fullest.

Highlights & What to See

• Lagoons of the Dunes: The park’s signature experience is swimming in the temporary lagoons that form between the dunes after the rainy season. Lagoa Azul and Lagoa Bonita are the most famous, with stunning turquoise waters.
• Sunset at the Dunes: Climb the highest dune near the entrance for a panoramic sunset that paints the endless white sand in shades of orange and pink.
• Off-Road Adventure: Join a 4x4 tour that bumps across the dunes to remote lagoons, stopping for dips and photo ops. Many tours also include a stop at the small fishing village of Atins, where you can try fresh local cuisine.
• Stargazing: With minimal light pollution, the park offers incredible night skies. Consider an overnight stay in a simple lodge to watch the Milky Way arc over the dunes.
• Wildlife Spotting: Keep an eye out for the park’s unique fauna, including the tiny, colourful frogs that thrive in the lagoons, and migratory birds like herons and terns.

Suggested Time to Spend

Most visitors spend a full day exploring the park, which is enough to see the main lagoons and catch a sunset. For a more immersive experience, allocate two days: one for a 4x4 tour covering the classic lagoons, and a second for a hiking or horseback ride to more remote areas. If you’re short on time, a half-day tour from Barreirinhas can still give you a taste of the dunes and a swim in a lagoon, but you’ll miss the full sweep of the landscape.

Nearby Areas Worth Combining

• Barreirinhas: The main gateway town, with plenty of accommodation, restaurants, and tour operators. It’s also a good base for exploring the Preguiças River, with boat trips to see mangroves and local villages.
• Atins: A laid-back beach village at the edge of the park, offering a more rustic stay, kitesurfing on the coast, and direct access to the dunes on foot or by 4x4.
• São Luís: The historic capital of Maranhão state, a UNESCO World Heritage site known for its colonial architecture, azulejo-tiled buildings, and vibrant culture. It’s a great start or end point for your trip.
• Delta do Parnaíba: South of the park, this river delta boasts a labyrinth of islands and channels, perfect for boat tours and wildlife watching, including capybaras and birds.
