Lençóis Maranhenses guide: best time, getting there, Atins and the traps that cost money

Some places make you think the photos must be edited. Lençóis Maranhenses is one of them. Then you stand on top of a dune for the first time, the sand soft and cool under your feet, and in front of you there is nothing but white all the way to the horizon – broken only by lagoons in turquoise, green and deep blue. No tree, no house, no sound except the wind. We spent three weeks in May 2026 in Atins, a fishing village made of sand on the edge of the park, and to this day it is the most impressive piece of nature we have ever seen.

This guide is the in-depth part of our Brazil travel story. Here you will find everything you really need for Lençóis Maranhenses: which base suits you, when the lagoons are full, how to get there cheaply, which tours are worth it, what it costs – and which mistakes cost you time, nerves and money.

Lençóis Maranhenses at a glance

“Lençóis” means bed sheets – and that is exactly what the landscape looks like from above: crumpled white sheets. The national park was founded in 1981 and sits on the Atlantic coast between the towns of Barreirinhas, Santo Amaro do Maranhão and Atins. The Preguiças and Parnaíba rivers carry sand from the interior to the coast, and the wind piles it inland into dunes. In the rainy season, roughly January to June, rainwater fills the hollows between the dunes. Because there is an impermeable layer beneath the sand, the water stays – until it evaporates in the dry season, according to Wikipedia by up to one metre a month.

UNESCO declared the park a natural World Heritage Site in July 2024. That has made it better known, but the sheer size swallows the visitors: ten minutes’ walk away from your tour group and you are alone.

Best time to visit Lençóis Maranhenses: when the lagoons are full

The most important question first, because it decides the whole trip. The lagoons are rainwater, and how full they are depends on each year’s rain. As a rough rule, according to the Brazilian travel portal Melhores Destinos:

Temperatures barely change through the year: around 29 to 32 °C during the day, rarely below 24 °C at night. The lagoon water is lukewarm. Cold is never the problem here – sun and reflecting sand are.

Tip: one or two weeks before you travel, ask your accommodation or a local agency for recent photos of the lagoons. That is more honest than any monthly table.

How to get to Lençóis Maranhenses

1. Fly to São Luís

The starting point is almost always São Luís, the capital of Maranhão. From Europe you usually change in São Paulo, Brasília or Fortaleza. We flew within Brazil – for the huge distances in the country, the most sensible option.

2. São Luís to Barreirinhas: bus, shuttle or rental car

The road is about 240 km long and paved. Scheduled buses (for example Cisne Branco) leave from the São Luís bus station; according to the portal Viaje Planejado, a ticket cost around R$ 65–75 per person one way in 2026, journey time just under 5 hours. Shared shuttles (vans) also pick you up at your hotel. We had a rental car via Discover Cars, collected at São Luís airport – about four hours later we were in Barreirinhas. The roads are fine, there are potholes and signposting is patchy. Download Google Maps offline and only fill up at big stations.

3. Barreirinhas to Atins

There is no paved road to Atins. You have two options: the 4×4 shuttle over sand tracks (as we did, about 1 hour 40 minutes according to the blog Viciada em Viajar) or the boat down the Preguiças river, either direct or as a tour with stops in Vassouras, at the Mandacaru lighthouse and in Caburé. Leave your rental car in Barreirinhas – a normal car will not make it through the sand.

4. Santo Amaro do Maranhão

Santo Amaro can also be reached from São Luís (about 240 km) or from Barreirinhas via a road of around 80 km. The last stretch in town is deep sand, so only 4×4 vehicles drive there. Since September 2023 the municipality has charged a tourist fee of R$ 10 per person, valid for three days (source: Melhores Destinos). According to the same source, Barreirinhas and Atins charge nothing.

There is no direct connection between Atins and Santo Amaro – except on foot. The multi-day crossing of the dunes is one of Brazil’s great hikes, and only to be done with a local guide.

Lençóis Maranhenses tours: what is really worth it

Good to know first: only licensed vehicles are allowed into the national park, so you cannot drive in with a rental car. Either book a tour or walk – which works well from Atins and Santo Amaro.

Lagoa Azul circuit (from Barreirinhas)

The classic and the shortest tour: about 40 minutes in an open 4×4 over sand tracks, then a walk to several lagoons close together, with swimming in two of them. The operator Enjoy Maranhão quotes from R$ 200 per person for the shared tour, about 3.5 hours, morning departure. Our lagoon tour from Barreirinhas cost around €25 per person in 2026 – prices vary a lot with season and operator.

Lagoa Bonita circuit (from Barreirinhas, afternoon)

For us the more beautiful choice: a ferry across the Preguiças river, a drive through the sand, then a steep climb up a high dune – 10 to 15 minutes that feel longer. At the top you see lagoons to the horizon. You swim in Lagoa Bonita and Lagoa do Clone, and the tour ends with sunset on the dune. That is the moment you fly here for.

Boat tour on the Preguiças river

A full day on the river: Vassouras with the “Pequenos Lençóis” (small dunes, often with monkeys at the edge), the Mandacaru lighthouse and Caburé – a narrow spit between river and sea with beach restaurants. If you are heading on to Atins, the tour can often double as your transfer.

From Atins: lagoons on foot or by buggy

This is why we recommend Atins to anyone with more than two days. From Atins you reach the dunes on foot or with a short buggy transfer. We went in the afternoon, waited for sunset on a dune – and nobody else was there. Popular spots are Lagoa Tropical and the beach at Canto do Atins, where two beach restaurants are famous for grilled shrimp (around R$ 200 for a dish for two, according to the blog Mala de Aventuras).

Kitesurfing, horse riding, scenic flight

From August to December a steady wind blows in Atins – the village fills with kitesurfers and there are beginner courses. Rides through dunes and lagoons are offered too. A scenic flight over the park (R$ 350 per person according to Viciada em Viajar, as of 2023) shows you the “bed sheets” from above – but check that the operator is licensed.

How much does Lençóis Maranhenses cost?

Day-to-day Brazil is cheap for Europeans, but Lençóis is a tourist area. Here is a range from verified sources and our own numbers:

Our three weeks in Atins

We had a house with a big covered terrace in the green, a hammock, solar panels and a pool at the neighbouring resort – via Airbnb, for around €50 a night. The laptop sat on the terrace table with Starlink next to it. Work in the morning, dunes in the afternoon, donkeys on the sand street in the evening and a sky that fades into pink and violet.

And then the part nobody told us beforehand: Atins depends on a single cell tower. If it fails, the whole village is offline – every provider, travel eSIMs included. That can last hours, sometimes days. For us it was the moment the Starlink idea was born: plug it into power or a power bank, and the internet is there. If you want to work, do your banking or simply stay reachable in Atins, take this seriously. More in our post Starlink on the road.

Lençóis Maranhenses: mistakes and traps that cost money

• Tours at midday: white sand reflects the sun mercilessly. Go early in the morning or in the afternoon for sunset – never onto the dunes at noon.
• July without a booking: July is Brazilian holiday season. Stays and transfers get scarce and pricier. Book early – or go in June or early August.
• Tours from the first street seller: compare two or three operators or ask your accommodation, and make sure the vehicle is licensed for the park.
• Rental car into the sand: trying to drive a normal rental car to Atins or into Santo Amaro ends in the sand – and expensively with the rental company. Park it in Barreirinhas.
• No internet backup: one tower for a whole village. Offline maps, cash in reserve and – if you work – Starlink.
• Using the wrong ATM: best are Banco do Brasil or Bradesco, not the yellow machines in shopping centres. The Wise card works almost everywhere, small vendors take Pix – and with Wise you can scan the Pix QR code directly.
• Heading into the dunes without bearings: the dunes all look alike. Pin your position on your phone, take enough water and be back before dark.

Lençóis Maranhenses: our verdict

Lençóis Maranhenses is not a place to tick off. It is a place that makes you go quiet. Allow enough time, pick your dates by the water, stay in Atins if you can and go into the dunes at least once in the late afternoon when the light turns soft. Then you will understand why we say: this is the most beautiful piece of nature we have ever seen.
