You reach Atins by water or by sand, never by asphalt. Perhaps that is why the village has managed to preserve its own rhythm: a handful of sandy streets nestled between the Preguiças River and the Atlantic, with the largest dune field in South America starting right where the last house ends.
The question every traveler asks before arriving is always the same: what to do in Atins? The answer depends less on a checklist and more on a perspective. Atins is not a destination of attractions, it is a destination of landscapes that shift from hour to hour. The very same dunes are one thing at five in the morning, another at noon, and something else entirely under the stars.
This guide gathers the tours, beaches, and lagoons that define a trip to Atins, complete with the duration of each experience and what to expect from every one.
Atins is located at the mouth of the Preguiças River, on the edge of Lençóis Maranhenses National Park, a UNESCO Natural World Heritage site since July 2024. Spanning 155,000 hectares of dunes, it features around 66,000 freshwater lagoons that form with the rains of the first half of the year and remain full for months.
The village is small, free of chain hotels and mass tourism, set in a transition zone between the Cerrado, Caatinga, and Amazon biomes. Everything is done on foot, on horseback, or in an authorized vehicle. Traffic within the park is restricted to ICMBio-approved operators, meaning every tour takes place with a guide and an authorized fleet. If you are still planning your arrival, start with how to get to Atins.
This is what brings most people here. The lagoons reach their peak fullness between July and September, when the water reaches waist height and the temperature invites you to spend the entire afternoon submerged. From October to December there is still water, with fewer people around. From January to March, the water mirrors recede and the journey becomes longer.
Morning departure for Gavião, Lagoa do Kite, and Lagoa do Charme, lunch at Canto do Atins, and in the afternoon, Maria Vitória, Três Marias, and sunset at Sete Mulheres.
Full day in a 4×4 across the Grandes Lençóis. Climbing the 70-meter dune opens up the broadest view in the park before taking a swim.
Half-day trip to Tropical and Esmeralda lagoons, with lunch at Ponta do Mangue or sunset in the dunes, depending on the chosen time.
ATV circuit through the dunes closest to the village. A light activity, ideal for your first introduction to the landscape.
The quietest way to cross the restinga coastal vegetation to the water. A slow, engine-free pace, with departures in the early morning or late afternoon.
All tours are private, for one to six people, with an ICMBio-accredited guide and fleet. The itinerary adapts to the month’s water level.
Each lagoon has its own character. Some are deep and dark, while others have a light sand bottom and look illuminated from within. The choice of circuit depends on the water levels during the month of your trip, which your guide evaluates the day before.

The second highlight of the trip is the freshwater of the Preguiças River. The speedboat leaves in the early afternoon and heads downriver to Mandacaru, the lighthouse village, where it is worth checking out the local handicrafts and sampling tiquira, a traditional Maranhão cassava spirit. Next come the dunes of Vassouras and the beach of Caburé, located on the narrow strip of sand between the river and the ocean.
The end of the journey is the main event. Around five in the afternoon, the boat pulls up to the mangroves and waits. Flocks of scarlet ibises arrive and blanket the trees in red as the sun sets over the river. It is one of the few spectacles that happens at the exact same time every day and still manages to astonish. For those short on time, a shorter version focused solely on the ibises’ flight leaves at 4:30 PM.
Lençóis changes completely depending on the light. Anyone with enough time should see the same landscape at three distinct moments, as they are essentially three different landscapes.
Departure at 4:30 AM, a half-hour ride to the dune, and breakfast served as the day begins. Return around 7:00 AM.
Departure at 4:00 PM for the late-afternoon dune, featuring a charcuterie and fruit platter set up on the sand. Return at 6:00 PM.
Departure at 8:00 PM into the desert without artificial light. Can be a stargazing circuit or a dinner served right on the dunes.
Dinner on the dunes requires reservation a day in advance, as the menu is selected ahead of time and the setup takes place before your arrival. The table is laid at the top of the sand, with the desert all around and no buildings in sight.
Not every day requires an itinerary. Atins rewards aimless wandering: the sandy streets, the buriti palms in the restinga, the hammocks in the shade, the small local shops. Late afternoon horseback rides follow the beach shoreline under the low light. And there is always the option of doing nothing, which here is never a waste of time.
Dining is also part of the experience. Charme Beach is a must-visit when in Atins. There, you can spend the entire day on the beautiful Atins beach with a drink in hand, listening to live music. Ça-Vá, located in the heart of Atins, serves Mediterranean cuisine infused with Maranhão flavors, led by chef Rafael Libério. The Sushi Bar, next to the Rancharia inn, offers an à la carte menu featuring fresh local fish. Mirante Charme Atins, set within the gardens of Atins Charme Chalés, serves home-style Maranhão dishes. In Atins, the distance between the dune and dinner is just twenty minutes.
At least three nights to cover the essentials: one day for the lagoons, one day for the river and the scarlet ibis flight, and a sunset over the dunes. Five nights leave room for the ocean, the village, and an unhurried day. Seven nights allow you to truly experience the destination rather than just visit it, offering plenty of leeway for the wind, rain, or simply repeating a favorite tour. Complete itineraries are available at 3, 5, and 7-night itineraries, and the full portfolio of activities can be found at experiences.
The list exists and it is all right here. But those who return from Atins rarely describe their trip through it. They describe the moment the car stopped at the top of the dune and everyone fell silent. The warm water of a lagoon at four in the afternoon. The sound of the wind rustling the thatched roof during a afternoon nap.
Grupo Charme Atins exists to handle the practical side of that equation—the logistics, the dining, the right guide on the right day—so you are left with time and attention for what cannot be planned. The best experience in Atins is usually the one you didn’t plan.
Our Charme Concierge helps you choose the tours based on the month of your trip, the water levels in the lagoons, and the pace you are looking for.
