Paulino Neves is where the paved road ends and the sand tracks begin — the gateway to the Pequenos Lençóis Maranhenses.

Paulino Neves is where the pavement ends and the sand begins. For those traveling the Route of Emotions (Rota das Emoções), this Maranhão municipality is the logistics link between Barreirinhas and the Parnaíba Delta — but beyond its role as a waypoint, it hides the nearly untouched lagoons of the Pequenos Lençóis Maranhenses and Lagoa do Barreiro Azul, a turquoise-blue lagoon certified for swimming.
Quick summary: Transit hub between the Lençóis and the Delta. Access to the Pequenos Lençóis and Lagoa do Barreiro Azul.
Paulino Neves is not a beach destination. It's a logistics hub: here, those arriving in a regular car switch to a 4x4 heading for the remote beaches, Caburé, and Atins. The MA-315 highway, fully paved since 2019, connects Barreirinhas to Paulino Neves in 38 km; on the other side of town, the sand tracks begin.
But the municipality holds surprises for those who stop for more than one night. The APA da Foz do Rio das Preguiças — Pequenos Lençóis — Região Lagunar Adjacente is an environmental protection area with dunes and intertidal lagoons that see virtually no tourists. Lagoa do Barreiro Azul, in the Povoado Tingidor settlement 7 km from the center, has existed since 2019 and has never dried up — it has a zipline, pedal boats, kayaks, a water slide, and a restaurant. Morro da Mendanha, a 60 m dune, delivers the most photogenic sunset in the region.
What you'll find:
What you WON'T find:
| Period | What to Expect |
|---|---|
| Jan–Jun | Rainy season — lagoons at maximum level, Barreiro Azul at its best, fewer tourists, lower prices |
| Jul–Sep | Start of dry season — lagoons still full, kite winds, growing visitor numbers |
| Oct–Dec | High season — more tourists, higher prices; Pequenos Lençóis lagoons may start receding |
Tip: The ideal window for the Pequenos Lençóis is June through September — full lagoons with the lowest tourist volume of the year. Lagoa do Barreiro Azul operates year-round.
Nearest airport: Parnaíba (PHB) — ~150 km, approximately 2h30 by car Alternative: São Luís (SLZ) — ~318 km, approximately 5h by car, via Barreirinhas
The most common route from Piauí is Parnaíba → Tutóia (~121 km via the MA-034, ~2h) → Paulino Neves (another 29 km paved). Those coming from Barreirinhas drive the MA-315 for 38 km of well-maintained asphalt.
From São Luís, the most practical option is renting a car or taking a transfer to Barreirinhas and continuing on the MA-315. There are no regional flights with a stop in Paulino Neves — access is always by road from the airports mentioned.
Within Paulino Neves: The town is small and you get around on foot or by mototaxi. For the Pequenos Lençóis, Caburé, and Atins, hiring a local 4x4 is mandatory — regular cars can't handle the sand sections.
The APA da Foz do Rio das Preguiças — Pequenos Lençóis — Região Lagunar Adjacente is an environmental protection area between Paulino Neves and Tutóia, with dunes and freshwater lagoons that see virtually no tourists. Unlike the main Lençóis at Barreirinhas, here the dunes coexist with coconut palms and mangroves, creating an oasis landscape that the main park doesn't have.

The typical tour departs from Paulino Neves by 4x4 or ATV and lasts 3 to 5 hours. The route crosses dune fields with stops at crystal-clear lagoons for swimming — the lagoons fill with rainfall from January to June and stay full until September. Outside peak season, you can have dunes and lagoons practically to yourself. The geological formation is the same as the main Lençóis: rain percolates through wind-blown sand until it reaches the impermeable layer of the Barreiras Formation, creating the intertidal lagoons between the dunes.
Access requires a 4x4 or ATV — local agencies run combined tours departing from Paulino Neves, priced in the range of R$ 80–150 per person (reference prices, confirm at time of travel).
Lagoa do Barreiro Azul, in Povoado Tingidor, is accessible by any vehicle on a dirt road. The turquoise-blue water has sanitary certification from the municipality. On site there's a zipline, pedal boats, kayaks, a water slide, a restaurant, and a camping area. There's a small entry fee per person. Morro da Mendanha, a dune of approximately 60 m within the APA, is the municipality's most famous viewpoint — the climb is steep but the panoramic view over fields, dunes, and beaches makes it worthwhile, especially in the late afternoon.


For those doing the full Barreirinhas–Atins crossing, Paulino Neves is the mandatory operational stop: refuel your tank (there are no gas stations between here and Atins), confirm the 4x4 for the sand sections, and adjust the itinerary according to the tide. Transfers head toward Caburé (~30–40 km along the beach, ~2h by 4x4) and Atins, connecting the coastal Lençóis region with the Parnaíba Delta.
Paulino Neves' food scene is simple and honest — family-run restaurants, beachside shacks, and snack bars in the center. The cuisine follows the Maranhão coastal tradition: fresh fish, shrimp, crab, and local seasonings.
In the town center:
At Praia do Barro Vermelho (4x4 access):

At Lagoa do Barreiro Azul:
General price range: R$ 20–45 for a set meal in the center; R$ 35–80 for seafood portions at beach shacks.
Paulino Neves has functional guesthouses aimed at travelers in transit. Don't expect resorts or high-end accommodation — the focus is on a quick rest before continuing the journey.
| Zone | Vibe | Best For |
|---|---|---|
| Center / MA-315 | Practical, near services and 4x4 agencies | One-day transit travelers |
| Outskirts with field views | Peaceful, more contact with nature | Those staying 2+ nights to explore the Pequenos Lençóis |
Reference prices: simple guesthouses run R$ 120–200 per night (double room); guesthouses with a pool and more complete amenities reach R$ 250–350. Confirm availability in advance for the July through September period.

Insider tips

No. Paulino Neves has no ATM. Withdraw cash before arriving — the nearest options are Tutóia (29 km), Barreirinhas (38 km), or Parnaíba (150 km). Larger guesthouses accept cards, but shacks, mototaxis, and 4x4 agencies only take cash.
Both. You can spend just a few hours here switching vehicles and moving on. But those who stop for two or three days have Lagoa do Barreiro Azul, the Pequenos Lençóis, and Morro da Mendanha to explore — all with far fewer people than the region's more popular spots.
No. The MA-315 is fully paved all the way to the center of Paulino Neves. A regular car gets there without any problem. The 4x4 is needed from here onward, for beaches, Caburé, Atins, and the Pequenos Lençóis trails.
Between June and September the lagoons are full — the result of rains from February through May — and tourist numbers are still low. Lagoa do Barreiro Azul doesn't depend on the season: it has existed since 2019 and has never dried up.
Exclusively by 4x4 along the beach (~30–40 km, ~2h). There is no paved road. Local agencies operate the route; departure time depends on the tide — confirm with the agency on the day.
It's 38 km on the MA-315, fully paved since 2019 — about 40 minutes in a regular car. A 4x4 is only needed beyond Paulino Neves, on the sand tracks.
