Santo Amaro: The Hidden Gem of Lençóis Maranhenses
Lençóis Maranhenses looks like a desert, yet for several months each year, thousands of turquoise lagoons fill the hollows between its white dunes. We’ve never seen anything quite like it. Of the three gateway towns, Santo Amaro is the closest to the dunes, which start right at the edge of the village. It’s also the quietest, and its lagoons are some of the most beautiful in the region. In this Santo Amaro travel guide, we share everything you need to plan your trip, from when to go to the best tours from town.
At A Glance
About Lençóis Maranhenses
Lençóis Maranhenses National Park in northeastern Brazil is a surreal landscape of vast white sand dunes filled with thousands of crystal-clear freshwater lagoons. It covers approximately 1,550 square kilometers (600 square miles), roughly twice the size of New York City.
During the rainy season, countless rainwater lagoons form among the dunes. Over several months of frequent rain, they grow large and deep enough for swimming. It’s ironic that despite looking like a desert, Lençóis Maranhenses receives two to three times more rain than London, a city famous for its gloomy weather. UNESCO lists the park as a World Heritage Site for its exceptional natural beauty and unique geology.
Best Time to Visit
May to September is the best time to visit Lençóis Maranhenses. By then, the rainy season has done its work, and the lagoons hold more water than at any other time of year. The weather also tends to settle, bringing the classic scene of turquoise water against white sand, perfect for swimming and photos.
June to August is the peak tourist season. The lagoons themselves aren’t usually crowded, but you’ll notice long lines at the entrance gate, busy restaurants, and fully booked inns. If you travel during these months, we suggest booking your accommodation well in advance. For a quieter trip, May and September are great months to visit.
From November to January, almost all the lagoons have dried up, leaving a more traditional sandy landscape. During these months, swimming is mostly limited to the few permanent lagoons that hold water year-round. The rains usually return in January, but it takes a few months for the lagoons to fill up again.
Gateway Towns
Lençóis Maranhenses has three gateway towns: Barreirinhas, Atins, and Santo Amaro do Maranhão. Each has its own character and leads to a different part of the park, so picking a base is the biggest decision in planning your trip. It comes down to your travel style and the kind of experience you’re after.
Barreirinhas📍 is the main gateway to Lençóis Maranhenses, with the widest range of accommodations, restaurants, shops, and travel agencies. It’s the liveliest of the three towns, and the dunes are about a 1-hour drive away on a bumpy road. Once there, rolling white sand stretches out like bedsheets spread across the land. That’s how the park got its name, since “lençóis” means “bedsheets” in Portuguese.
Atins📍 is a rustic fishing village with sandy streets, right by the ocean. It has a relaxed, bohemian feel, with an incredible selection of charming boutique hotels and high-end seafood restaurants. That makes it a top choice for accommodation and dining quality. It’s also famous for world-class kitesurfing. The dunes here slope gently toward the coast, and at Canto do Atins, they run straight into the Atlantic waves.
Santo Amaro📍 is a small, peaceful village where the dunes start right at the town limit. It’s perfect for nature lovers who want fewer crowds and wild landscapes. Accommodation and restaurant options are limited, but it’s the best choice for lagoon quality.
If your time in Lençóis Maranhenses is short, we recommend sticking to one town. This way, you spend your days in the dunes rather than on the road between bases.
Getting There
The closest airport to Lençóis Maranhenses is São Luís International Airport (SLZ)📍 in the capital of the state of Maranhão. There are daily domestic flights from major Brazilian cities, including São Paulo, Rio de Janeiro, Belém, Salvador, and Brasília. LATAM, GOL, and Azul airlines operate these routes. TAP Air Portugal also flies direct from Lisbon twice a week.
From São Luís, we recommend a private transfer for flexibility, and convenience. The journey to Santo Amaro or Barreirinhas takes about 4 hours, with a stop for lunch and a bathroom break. To reach Atins, you’ll first travel to Barreirinhas. From there, the last stretch to Atins is half the fun: a 1-hour scenic boat ride or a 1-hour drive across the dunes.
We booked our round-trip transfers to Santo Amaro with Caetés Expedições, who also organized all of our private tours in the dunes. You can also arrange everything through your accommodation.
How Long to Stay
For most travelers, 3 to 4 nights in Santo Amaro is the sweet spot. That leaves room for two or three full-day tours, each exploring a different corner of the park. If your flights allow, a half-day tour on your arrival or departure day adds one more lagoon to the list.

With 5 nights or more, we suggest splitting your stay between Santo Amaro and Atins. The two towns show very different sides of the region, and Atins adds some beach time to your days in the dunes. A week or longer is enough to see all three gateway towns and the lagoons around each one.
What Makes Santo Amaro Special
Santo Amaro sees fewer visitors than Barreirinhas and Atins, and it isn’t yet overrun by tourism. With its sandy streets and rustic charm, the village feels authentic and unhurried.
The town’s location is hard to beat. Santo Amaro sits right at the edge of the national park, just 5 to 10 minutes by car from the first lagoons. Less time on the road means more time in the water, surrounded by some of the park’s most impressive and untouched scenery. The dunes around Santo Amaro are some of the tallest in Lençóis Maranhenses, and its lagoons are among the largest and deepest. That depth gives the water an especially vivid turquoise and deep blue color. The town is also the starting point for remote circuits like Rancharia and Ponta Verde, where it’s not difficult to have a lagoon all to yourself.
Days in the dunes are easy and comfortable here, too. Authorized 4×4 vehicles can drive right up to the edge of the larger lagoons, so most tours bring beach chairs and a parasol to set up right by the water.
Some lagoons around Santo Amaro also keep good water levels later into the year, often through October. This can stretch the lagoon season a little longer on the Santo Amaro side.
Where to Stay in Santo Amaro
Accommodation options in Santo Amaro are limited, so we suggest making your reservation at least six months in advance. Here are the most charming inns in town.
- Quintal de Areias: This is where we stayed. It’s a small, charming inn with only four comfortable, air-conditioned bungalows, each with indoor and outdoor showers. A peaceful garden with hammocks and exceptional, thoughtful service make a stay here deeply relaxing. Several of the best restaurants in town are within walking distance, too.
- Villa Malie: With its romantic boutique style, Villa Malie is a comfortable, photogenic sanctuary to return to after a day in the dunes. Each room comes with either an outdoor bathtub or a private pool, and its central location puts local shops and restaurants within easy reach.
- Pousada Rancho das Dunas: The standalone chalets offer genuine privacy in a cozy, nature-connected setting. The on-site restaurant, Cozinha do Rancho, anchors the stay with excellent regional cuisine, so a high-quality dinner is always just steps from your door.
Best Restaurants in Santo Amaro
- Maravie Gastrobar📍: One of the newest restaurants in town, Maravie opened in 2026 and is especially good for seafood. The ceviche and the panelinha de frutos do mar (mixed seafood with house toast) are both excellent starters. For a main, we recommend the shrimp pasta.
- Guajiru Restaurante📍: Guajiru was a tip from our guesthouse, and a good one. We loved the Guajiru octopus, and the side dishes complemented it perfectly. You can reserve a table via WhatsApp and even preorder your meal, so it arrives soon after you sit down.
- Cozinha do Rancho📍: The restaurant at Pousada Rancho das Dunas is highly rated, with a beautiful, cozy setting. The menu centers on authentic Maranhense cooking, with plenty of seafood alongside classic Brazilian dishes.
- Quintal de Areias📍: The guesthouse where we stayed also runs a tiny restaurant that welcomes non-guests. The menu is small but authentic, with homemade regional dishes made from fresh, local ingredients. Tables sit in a tranquil open-air garden lit by candles and lanterns. Mosquito repellent comes in handy in the evenings.
A Typical Day in the Dunes
All tours in Lençóis Maranhenses National Park are guided and use off-road vehicles built for the dunes. Half-day tours typically run from 9:00 AM to noon, or leave at 3:00 PM and return just after sunset. Full-day tours usually start at 9:00 AM and also return after sunset.
On a full-day tour, you spend the morning driving through the dunes, swimming in lagoons, and strolling along dune ridges.
Around midday, the tour stops at a remote local village for lunch, which you choose from a menu at the start of the day. After the meal, everyone settles into a shaded hammock, following a cherished daily ritual across northeastern Brazil. In the afternoon, you head back out for a swim at another lagoon.
The last stop is a high dune, where you watch the sunset before driving back to Santo Amaro just as it gets dark.
Best Tours From Santo Amaro
Booking tours from Santo Amaro is easy, either online before your trip or once you’re in town. Most operators follow the same routes. Where they differ is in group size on shared tours, whether they offer private tours, and how well equipped they are.
We had amazing private tours with Caetés Expedições: Rancharia Circuit, Ponta Verde Circuit, and a half-day trip to Lagoa do Maçarico. All our tours included a parasol, beach chairs, towels, fruit, and a cooler with cold drinks.
Rancharia Circuit
This full-day tour visits the lagoons near the village of Rancharia, with free time for swimming and photos. Even the drive from Santo Amaro is absolutely stunning, crossing dune fields dotted with lagoons. Of all the tours we did, this was the most beautiful. The route is one of the most rugged and least crowded in the park.
Because Rancharia Circuit sits in a lower-lying area of the park, some lagoons can hold water longer into the dry season.
Ponta Verde Circuit
Another full-day option takes you to the lagoons around Ponta Verde village. Unlike other dune routes, this circuit mixes white sand dunes with pockets of green vegetation. The greenery makes it the liveliest of the circuits, with chances to spot birds like herons and scarlet ibises. You may also see donkeys, cows, and pigs from the nearby villages.
The lagoons here are turquoise with a greener tone. The tour includes several swimming stops, lunch at a local village, and sunset from the top of a dune.
Betânia Circuit
Along with crystal-clear lagoons and massive white dunes, this full-day circuit stops at the traditional riverside village of Betânia. Unlike many other dune tours, it shows you how families live day to day inside the national park.
Lagoa do Junco
Lagoa do Junco is a half-day trip from town, usually in the afternoon. It’s one of the largest and deepest lagoons around Santo Amaro, with some of the clearest, most vivid emerald-green water in the national park.
Lagoa do Maçarico
Lagoa do Maçarico takes its name from the maçarico, the Portuguese word for sandpiper, a migratory bird that passes through the area during the lagoon season. We visited on a half-day tour, and it felt wonderfully peaceful. Like many lagoons on the Santo Amaro side, its water is remarkably clear. It shifts between deep blue and light turquoise, depending on the depth and the angle of the sun.
If you search for “Lagoa do Maçarico” online, you’ll likely find reviews for a different lagoon with the same name near Barreirinhas, part of the Lagoa Bonita circuit.
Final Thoughts
Lençóis Maranhenses is one of the most unique places we’ve ever seen, and Santo Amaro made it easy to enjoy at a slower pace. The dunes start right at the edge of town, so more of each day goes to swimming in clear lagoons and walking along dune ridges. On the remote circuits, it’s not hard to find a lagoon all to yourself.
Santo Amaro suits nature lovers who value peace, quiet, and raw natural beauty. The town is small and rustic, with just a few charming inns and restaurants, so it’s worth booking early. For a 3- to 4-night stay focused on the lagoons, it’s a wonderful base.
