About Lençóis Maranhenses
Along the undulating white sand dunes formed by the wind, countless rainwater lagoons are formed during the rainy seasons in Lençois Maranhenses National Park. Due to the high volume of rainfall, the bodies of water become large and deep enough for swimming and diving.
The beauty of Lençóis is so otherworldly it got to Hollywood, serving as the setting for the fictional planet Vormir in Avengers: Infinity War. Amidst CGI effects, the dunes host the villain Thanos and his daughter Gamora in a few scenes from the film.
The park has been protected by federal Brazilian law since 1981 and was declared a UNESCO World Heritage Site in 2024.

Is Lençóis Maranhenses a desert?
Lençóis Maranhenses is what we call “a desert with a thousand lakes”. As a wet desert, it’s a broad area of sand dunes and high biodiversity, covered with over 36,000 rainwater lagoons.
.
Therefore, Brazil does not have vast arid deserts like the Sahara, though there are places undergoing desertification processes, such as the Caatinga biome.
Where is Lençóis Maranhenses located?
Lençóis Maranhenses is located in a 155,000 ha area on the coast of the state of Maranhão, in the northeast of Brazil.
Barreirinhas, Atins, and Santo Amaro are the gateways for the national park, providing enough infrastructure to comfortably welcome tourists from all over the world.
How to get to Lençóis Maranhenses National Park?
To reach the breathtaking expanse of the Lençóis Maranhenses National Park, adventurers can set off from three entry points—all easily accessible from São Luís, capital of Maranhão, where Marechal Cunha Machado International Airport (SLZ) is located:
.
- Barreirinhas: the main gateway, 260 km east of São Luís. Options include buses, rental cars, shared vans, and private transfers.
- Atins: accessible via Barreirinhas. From there, you can take a scenic boat ride along the Preguiças River or a 4×4 vehicle ride. Both options offer unique experiences and beautiful views.
- Santo Amaro: 237 km southeast of São Luís, it’s a quieter alternative to Barreirinhas. Rent a car in São Luís to drive straight to Santo Amaro, or take a shared van service.
- Pro tip: when you book your Lençóis Maranhenses tour with PlanetaEXO, our local partners provide shuttle services from the airport/hotels in São Luís to your accommodation in one of the base cities. Talk about convenience!

When is the best time to visit Lençóis Maranhenses?
The ideal time to visit Lençóis Maranhenses in Brazil is from May to September. During this period, the lagoons are at their fullest, providing visitors with the best possible experience. Perfect for swimming, diving or simply relaxing in the crystal-clear waters!
.
From September to October and February to April, the lagoons start to decrease but still offer plenty of action in the water. While the scenery might not be as lush as during the high-water season, these months are known for fewer crowds and enjoyable activities in the lagoons.
From November to January, the lagoons dry up, limiting water activities and revealing pastures and meadows on the lagoon floors. This period shows a different side of Lençóis, highlighting the changing landscape and the unique formations of the park.

What to do in Lençóis Maranhenses National Park?
Besides its jaw-dropping beauty, this is a destination ideal for travelers who love the outdoors and can’t say no to adventure. Watching the sunset from the sand dunes is an experience unlike any other, but there’s a lot more to do in Lençóis Maranhenses.
Lagoons
Across the national park, there are thousand of lagoons of all sizes, which appear and disappear depending on the time of year.

They all have their virtues, but some stand out for their beauty, size, and permanence even during times of drought:
- Barreirinhas: Lagoa Azul and Lagoa Bonita
- Atins: Lagoa Tropical and Lagoa da Capivara
- Santo Amaro: Lagoa da Betânia, Lagoa da Andorinha and Lagoa da Gaivota
Can I swim in Lençóis Maranhenses?
Yes, you can swim in Lençóis Maranhenses! The lagoons are clear and have just the right temperature for swimming, diving or simply relaxing.

However, it’s important to follow the guides’ instructions and respect the park’s rules to ensure a safe and responsible experience. This includes avoiding the use of cosmetics that could contaminate the water and picking up your own trash.
Trekking
Those seeking total immersion can cross the national park on foot. The trek lasts 3–5 days and allows you to explore the sand dunes and lagoons located in the so-called “primitive zone” of Lençóis Maranhenses.

After long hours of trekking, travelers spend the night in the homes of locals who generously open their doors to welcome them. The accommodations are modest but cozy.
The experience requires time and physical effort, meaning not everyone is ready to face it. However, visitors who are willing to embark on this adventure do not regret it and return home transformed!

Beaches
The Lençóis Maranhenses National Park is bordered by the Atlantic Ocean, especially at the mouth of the Preguiças River.
While somewhat famous, Atins Beach is not very crowded due to its fairly remote location in Atins and relatively difficult access—only by boat or 4×4 vehicles.
.
The beach is gorgeous, with calm waves, warm waters and light-colored sand. In addition to being great for relaxing and sunbathing, it’s also one of the main kitesurfing spots in Brazil. Therefore, the sky is always adorned with colorful kites that only make the view even more beautiful.
Caburé Beach (Barreirinhas) and Travosa Beach (Santo Amaro) are also worth the visit!
Boat rides and boiacross
The landscape of Lençóis is not limited to sand dunes and lagoons but also includes green areas bathed by the Preguiças River. Passing through Barreirinhas, Atins, Vassouras, Mandacaru and Caburé, navigating its dark waters is a great way to truly get to know the region.
.
Tourists are also attracted by the Formigas River, which cuts through the village of Cardosa. The current is perfect for boiacross, a popular ecotourism activity in Brazil where people float down the rivers in large inflatable tubes.
How many days should I stay in Lençóis Maranhenses?
Knowing how long the trip will last is key to your planning. Lençóis Maranhenses National Park offers experiences ranging from quick introductions to deeper, multi-day adventures.
.
If your time is limited, a 2-day tour is enough for a taste of the sand dunes and lagoons. For a more immersive experience, 3 to 4 days allow you to explore different regions of the park, join longer hikes, or take boat trips along the Preguiças River.
If you’re able to stay 5 days or more, you can enjoy more ambitious adventures, such as multi-day treks crossing the park or embarking on the wonderful Route of Emotions, a fantastic tour that includes destinations (Lençóis, Delta do Parnaíba, and Jericoacoara) in three different states (Maranhão, Piauí, and Ceará)!

Atins is a peaceful fishing village by the sea, known for its rustic charm and relaxed pace. It’s ideal for travelers looking for a quieter atmosphere in cozy, more intimate hotels.
Santo Amaro offers an even more remote and exclusive experience. With fewer visitors and inns surrounded by sand dunes and lagoons, it’s the perfect picture of tranquility and total disconnection.
