The Rio Preguiças Crossing

The boat leaves from Avenida Beira Rio, opposite the O Bambu restaurant. The direct crossing doesn't include a pickup from your guesthouse: walk or take a moto-taxi, and be at the boarding point 15 minutes before departure.

Fiberglass speedboat with an outboard motor, ~6-13 people.

Crossing or Tour?
The direct crossing is transport: about 1h to Atins, with your luggage on board. The boat trip along the Rio Preguiças is something else: a full day (~7h30) with stops along the way, ending back in Barreirinhas. Some tours can drop you in Atins with your luggage if you arrange it in advance. Confirm that the stops, your luggage and the drop-off in Atins are included.
Schedules
The times below are references published by operators, not one timetable for every day. Confirm an available departure before arranging a connection:
| Direction | Reference times |
|---|---|
| Barreirinhas → Atins | Around noon–12:30pm. Some offers also list 4pm |
| Atins → Barreirinhas | Advertised options at 7am and 2pm. Confirm for your date |
For a private boat, agree on the time and availability when booking. Saturdays and public holidays also need confirmation — send us your date and we'll check who runs that day.
Tip: For the van connection to São Luís, ask about the 7am option and confirm the connection too — a planning example for a booked flight is in the São Luís → Atins guide.
Saturdays and Public Holidays
Confirm service for your travel date. Availability varies by company and date.
If you are traveling on a Saturday or public holiday:
- Shared boat: confirm the departure and seats before booking the connection
- Private boat: agree on the time and availability when booking
Overland alternative
The overland 4×4 route must follow the road outside the park, in accordance with the July 2026 ICMBio circular. One of the options described is the jardineira (a 4×4 truck, ~R$40, departs early in the morning (confirm the day before), ~2h ride) — the cheapest option. Fair warning, though: in high season the sand road gets seriously bumpy from the constant tour traffic. The boat is faster, more comfortable, and the scenery is incomparable — we strongly recommend the boat. Confirm transport conditions and availability before booking.
What to Bring
- Hat/cap (intense sun)
- Sunscreen
- Water
- Protect your luggage from the spray
Arriving in Atins
The boat docks at the Atins port, on the riverbank. From there:
- On foot: Most guesthouses are a 5-15 min walk away (sand streets)
- Quad-taxi (quad bike): ~R$10-20 — in Atins there are only quad-taxis
- No pavement: All of Atins is sand — wear flip-flops

Why It Seems Simple But Isn't
The crossing itself is smooth. The problem is coordination:
- Companies change their WhatsApp numbers
- Advertised times vary by company and date
- Saturdays and public holidays need confirmation
- In Atins, some include the ride to your guesthouse, others don't
A poorly coordinated booking = an unplanned night in Barreirinhas. We live in Atins and check who runs on your day — talk to us.
