Make your days count
Lençóis Express
Two Lençóis bases, returning to São Luís. Compare the time spent arriving, exploring and changing accommodation.
São Luís → Barreirinhas → Atins → São Luís
Before you finalize your plans
Count arrival and return days
Barreirinhas is where you first choose your excursions; Atins adds a stay near the mouth of the Rio Preguiças. Visiting both bases takes travel time. In three days, every day includes an arrival or base change; four, five and seven days create room between those stages.

Lençóis Maranhenses in 3 days: Barreirinhas, Atins and the return
One night in Barreirinhas and one in Atins. Every day includes an arrival or base change, and the last day is for the return. Excursions depend on the time left. If these connections do not fit your dates, compare four or five days or replan the trip around one base.

A suggested plan
Lençóis Maranhenses in 4 days: Barreirinhas, Atins and the return
One night in Barreirinhas and two in Atins. An early van from São Luís takes about 4 hours, leaving the afternoon of day 1 for a lagoon circuit. On day 2 the shared boat takes about an hour to Atins, with time left for the beach; the Rio Preguiças tour can also serve as the transfer with luggage, but only on request. Day 3 is for a lagoon circuit from Atins or, in season, kitesurfing. On the other hand, you give up Santo Amaro and a second Barreirinhas circuit, and day 4 is all travel: an early boat and a van, about 6 hours to São Luís, so plan on an evening flight or one more night in the capital.

Lençóis Maranhenses in 5 days: Barreirinhas, Atins and the return
One night in São Luís, two in Barreirinhas and one in Atins. The day between arrival and departure in Barreirinhas lets you prioritize a lagoon circuit or the Rio Preguiças. Atins still has one night; plan that visit around arrival and return times.

A suggested plan
Lençóis Maranhenses in 7 days: Barreirinhas, Atins and the return
One night in São Luís, three in Barreirinhas and two in Atins. Two days between arrival and departure in Barreirinhas and one in Atins give more room for lagoons, the river and village time. Excursions still depend on conditions during your visit. Santo Amaro is left out to limit base changes, but with six nights or more it is the most common addition, and its lagoons tend to hold water longer at the end of the dry season.

Planning reference: rain, wind and lagoons vary from year to year. Check conditions for your trip.
Best time for each section
Rain: 1991–2020 climate normals from Brazil's INMET for the Chapadinha (MA) station, the nearest with an official series — an indicative reference.
Wind: 1991–2020 monthly means from the ERA5 reanalysis (Copernicus, via Open-Meteo), 10 m above the surface, at the Atins (MA) grid point — an indicative reference; on the beach the wind can be quite different.

The colors summarize each month for this itinerary. Outside June to September there are still lagoons, just fewer and smaller.
- 🌊 Lençóis Lagoons — June to September is a planning reference for the lagoons. Water levels vary with rainfall and between circuits; check which excursions suit conditions close to your trip.
- ☀️ Choosing your month — Start with lagoon season, then compare the dates you can travel. The shortest version leaves little room to rearrange excursions if conditions change.
- 🌦 Outside the main season — There are lagoons all year: at the end of the dry season they are fewer and smaller, and agencies take tours to whichever are in the best shape. From February to April, rain tends to fall mostly at night and rarely lasts all day. In the low season, November to March (apart from New Year's week), prices tend to be lower, the pace is calmer and there are far fewer people, though some businesses close; in Atins, kite season can run into January.
Before you finalize your plans
Arrival, return and available time
Count the days from São Luís: The 3- and 4-day versions assume you are ready to leave early on day one. The 5- and 7-day versions include an initial night in São Luís. Flying in may require time outside the itinerary's days.
Coordinate road and river: See São Luís to Barreirinhas and Barreirinhas to Atins. Choose between a direct boat transfer and a Rio Preguiças excursion depending on the time you have; confirm which service reaches your agreed destination.
Keep the final day for the return: Every version returns to São Luís. Confirm departure from Atins, the connection in Barreirinhas and arrival before choosing your flight. An approximate journey time does not guarantee a flight connection.
Prepare for your stay: Ask your accommodation about arrival arrangements, accepted payment methods and what to bring for your chosen excursions. A one-night Atins stay needs particular attention to arrival and departure times.
Frequently asked questions
How many days do I need for Lençóis Maranhenses?
This guide offers 3, 4, 5 or 7 days between São Luís, Barreirinhas and Atins, including the return. The 3-day version allows one night in each Lençóis base and requires an early departure from São Luís on day one; the 4-day version keeps that early start and adds a second night in Atins. The 5-day version includes one night in São Luís, two in Barreirinhas and one in Atins; the 7-day version increases Barreirinhas to three nights and Atins to two. Santo Amaro is not part of these versions.
What's the Barreirinhas to Atins transfer like?
Direct transport and the Rio Preguiças excursion are different services. A 9am departure reference generally describes the excursion; do not use it as a guarantee for the direct boat. Check the leg's section and confirm operator, time, fare, baggage and arrival point for your date before planning the day in Atins.
Is it worth including Atins in the itinerary?
Choosing both bases combines excursions from Barreirinhas with an Atins village stay near the mouth of the Rio Preguiças. The tradeoff is base-change time, especially in three days. If you prefer fewer journeys, compare a single-base stay; that needs a different excursion and return plan, rather than simply deleting the Atins night.
When are the Lençóis lagoons full?
June to September is a planning reference for visiting the lagoons, but water levels depend on rainfall and vary between circuits and years. Check conditions close to your trip. Outside that window, ask which excursions make sense; the calendar cannot promise every lagoon will be full or establish that a visit is no longer worthwhile.
Can I combine Lençóis Express with Jericoacoara?
To include Jeri, compare the Rota das Emoções and Jericoacoara to Lençóis Maranhenses guides. Their stages, overnight stops and entry and exit points differ from this São Luís round trip. The Jeri-to-Lençóis guide's 5, 7 or 10 days cover that whole trip, not extra days to add automatically to Lençóis Express.
