Seasons, locations, safety tips, and health precautions. See our recommendations for an unforgettable travel experience in Brazil’s Lençóis Maranhenses National Park!
Located in northeast Brazil, Lençóis Maranhenses National Park is a destination sought after by adventurers from all over the planet. Recognized as a UNESCO World Heritage Site, this natural wonder is famous for its vast, giant white sand dunes and crystal-clear freshwater lagoons.
But don’t let its otherworldly beauty fool you—exploring this fantastic place requires thoughtful planning to make the most of your time, energy, and budget. Considering elements like location, weather, and activities, following some Lençóis Maranhenses travel tips can help to make your vacation even more memorable.
That’s why PlanetaEXO, an ecotourism platform specialized in Lençóis Maranhenses tours, has put together 10 essential recommendations for a wonderful experience in one of the most beautiful places in Brazil. Check them out below!
1. Pick your base city: Barreirinhas, Atins, or Santo Amaro
The choice of base cities can shape your entire experience, so analyzing the options and choosing the one that makes the most sense for your travel style is the first tip to thoroughly enjoy Lençóis Maranhenses.

Barreirinhas is the most popular hub, with solid infrastructure and easy access. Atins is a peaceful fishing village, harder to reach, but offering rustic charm and great conditions for kitesurfers. Meanwhile, Santo Amaro has the closest access to the national park and beautiful lagoons, but restaurants, bars, and other services are rather scarce.
Besides considering the different atmospheres and logistics of each base, it’s also possible to combine more than one city throughout a single trip. This way, you can experience each side of Lençóis!

2. Time it right: when the lagoons are at their best
The weather is ideal for those looking to explore ecotourism in Brazil. The best time to visit Lençóis Maranhenses is between May and September, when the lagoons are full from seasonal rains and the sky is usually clear with no rain. This window offers the most spectacular views and the best overall conditions for hiking and swimming.
.
From February to April, the heavy rainfall might disrupt travel plans, while the period between November and January causes the lagoons to shrink or disappear completely.
Lençóis offers great experiences all year round, but the itineraries vary according to the seasons. Make sure to check the weather forecast and plan your trip according to your preferences!
3. Health tips: vaccination and fighting the heat
Foreign tourists are not required to get vaccinated, but Brazil’s Ministry of Health recommends that visitors from other countries be protected against diphtheria, tetanus, polio, and measles.
.
Additionally, as a precaution, it is advisable to get vaccinated against yellow fever and hepatitis A and B—even though there is no imminent risk of these diseases within national territory.
The heat is also something to consider, as Lençóis Maranhenses is located in one of the hottest regions in the entire country. To protect yourself against the intense sun and high temperatures, always apply sunscreen, wear a cap/hat when exploring the sand dunes, and stay well-hydrated at all times.

4. Trust the locals
One of the best Lençóis Maranhenses travel tips is to trust the locals for a truly immersive, fulfilling experience.
Lençóis is a protected area with no marked trails. As the dunes stretch endlessly, it’s easy to lose your sense of direction. Tour guides know the safest and most scenic routes, how to avoid getting lost, and can tailor your experience to your interests. Remember: never venture into the national park without a qualified professional.

Local residents also play an important role in the stay experience, as many travelers making the dune crossing, which can last several days, spend the night in the homes of locals within the park.
The accommodations are simple, yet clean and comfortable—ideal for resting a weary body after a long day of trekking. This is also a wonderful way to meet new people and connect with Brazilian and Maranhense culture.

5. Lençóis Maranhenses treks are demanding (be prepared!)
Expect a workout. The sand is uneven and the dunes are tall, so the ground slips out from under your feet as you walk.
.
Under the hot sun, physical exertion becomes even greater. To avoid stressful situations, exhaustion, and other health issues, dress in light, airy clothes, drink plenty of water, and don’t rush. And while most people enjoy walking barefoot, hiking sandals work just fine!
All this effort and dedication are worth it: you will be rewarded with landscapes that seem out of this world and indescribable experiences to carry with you for the rest of your life!
6. Pack smart
Pack smart, light, and functional. Comfortable, appropriate items for physical activities and warm weather are indispensable:
- Swimwear
- UV-resistant clothing
- T-shirts
- Shorts
- Flip-flops
- Sandals or light hiking shoes
- Socks
- Hats or caps
- Towels
- Sunglasses
- Reusable water bottle (at least 1.5L)
- Eco-friendly sunscreen (non-toxic to aquatic life; SPF 30 or higher)
And, as with any other trip, don’t forget the essentials: documents, insect repellent, medication, a power bank, and chargers (phones, cameras, laptops, and tablets).
Bring your own cash (Brazilian real), as ATMs are scarce (especially in Atins and Santo Amaro), and connectivity for debit/credit cards is limited.
7. Don’t underestimate transfer times
Lençóis Maranhenses National Park is located in a remote area. From the capital of Maranhão, São Luís, to the base cities, the drive takes between 4 and 5 hours.
.
When planning your vacation, map out the round-trip transfer to ensure you enjoy every single second and to avoid any problems with your schedules—like missing a flight, for example.
Your trip should last at least 3 days, but it obviously depends on your availability and the type of experiences you’re looking for.
8. Go for multi-day treks
Speaking of how many days should you spend in Lençóis Maranhenses, if you’re up for a real adventure, consider trekking across the dunes from one village to another.
This is a more intense experience than the day tours, but far more rewarding. You’ll hike through remote parts of Lençóis Maranhenses that most visitors never see, sleep in locals’ homes or campsites, and enjoy simple, home-cooked meals.
.
In the afternoons, after the hikes, you’ll have a few quiet hours to relax and recharge. It’s the perfect moment to disconnect, take a nap, or simply admire the breathtaking beauty that surrounds you.
9. Bring your own snacks and drinks on the tours
Lençóis tours typically only stop during lunchtime, and there are no restaurants or diners inside the national park. If you plan to spend several hours (or even days) in Lençóis Maranhenses, it’s important to bring your own food and water.
Opt for light, non-perishable snacks such as crackers, nuts, protein/fruit bars, etc. Use reusable containers and keep the packaging in your backpack to dispose of it once you return to the city. Never litter in the dunes or lagoons.
10. Download Google Translate for offline use
Don’t expect English everywhere; most locals only speak Portuguese.
Downloading Google Translate (or other translation apps) before arriving and setting up the Portuguese language pack for offline use is highly recommended. This will help with everything you might need, from ordering food to asking for directions.
.
Take the opportunity to learn a few basic words in Portuguese, like “bom dia” (good morning) and “obrigado” (thank you). Small gestures like these show kindness, openness, and appreciation for the people and the place you’re visiting!
