The question of how many days in Lençóis Maranhenses is key to planning your adventure. The time you spend here depends on how many days you can dedicate to exploring its lagoons, dunes, remote villages, and unique desert scenery.
You should plan to spend between 2 and 7 days in Lençóis Maranhenses, depending on your availability and the level of immersion you’re looking for. This destination offers multiple opportunities for connection with nature, culture, and adventure. Whether trekking across vast dune fields, relaxing by freshwater lagoons, or engaging with local communities in remote oases, each day reveals a new side of this extraordinary region.
A short 2-day stay offers a quick introduction to the dunes and lagoons. In 3 to 4 days, you can enjoy more immersive treks or relaxed tours starting from Santo Amaro or Atins. For full immersion, 5 or more days allow you to reach remote oases, cross the park on foot, and even combine Lençóis Maranhenses with other destinations like the Parnaíba Delta or Jericoacoara in Ceará. When asking yourself how many days to spend in Lençóis Maranhenses, consider both travel logistics and the type of experience you want.
Created in 1981, the Lençóis Maranhenses National Park covers 1,550 km² along 70 km of Atlantic coastline, spanning the municipalities of Barreirinhas, Santo Amaro, and Primeira Cruz. In 2024, it earned UNESCO World Heritage status, recognized for its rare combination of coastal dunes, seasonal lagoons, and ecosystems shaped by Amazon, Cerrado, and Caatinga influences.

What Determines How Long You Should Stay in Lençóis Maranhenses?
Logistics and Access
Lençóis Maranhenses is remote, with three main gateways: Barreirinhas, Santo Amaro, and Atins. Reaching the park requires a transfer from São Luís, taking 4 to 6 hours depending on your final destination and transport type. Options include shared vans with fixed schedules or private transfers for more flexibility. Travelers heading to Atins will need an additional boat or 4×4 leg from Barreirinhas, which may influence how many days you’ll want to allocate for your trip.

Season and Weather
The best time to visit is from May to September, when the lagoons are full and ideal for swimming. From October to December, as the lagoons dry up, the landscape shifts to wide open sand fields, offering striking scenery for photography, sunset views, and exploring areas that are harder to reach during the rainy season.
With daytime temperatures ranging from 28°C (82.4°F) to 34°C (93.2°F)year-round, and strong sun with little shade, both the weather and the environment will influence how long you should stay in Lençóis Maranhenses and what kind of experience you’ll have.
Your Travel Style and Pace
Whether you dream of multi-day treks sleeping in hammocks at remote oases, camping among the dunes, or enjoying comfortable inns in Santo Amaro, Barreirinhas, or Atins, there’s an itinerary for every style. Some routes cover up to 70 km on foot, offering full immersion into the park’s dunes and lagoons. Others include short hikes combined with 4×4 rides, ideal for those seeking less physical effort without missing the region’s natural beauty and cultural richness. Along the way, you’ll also have the chance to visit traditional villages, meet local families, and experience the everyday life and culture of the communities that call Lençóis Maranhenses home.
