Quick summary: ~40km on the Rio Preguiças, about 1h by boat (50min–1h20), R$70-150/person.*

The recommended way to reach Atins is by boat, along the Rio Preguiças — one of the most beautiful crossings in the region. There's also an overland 4×4 route through the park (some operators already run it), but we strongly recommend the boat.

Price	From ~R$600 (up to ~R$1,470 for ~10 people)*
Capacity	Up to ~10 people

Schedules

Schedules vary with the tide and demand — confirm before you book. In general, the Barreirinhas → Atins departure leaves around midday (~12pm–12:30pm), and the 7am and 2pm slots are usually the return trips (Atins → Barreirinhas).

Tip: To connect with a transfer to São Luís, take the morning return from Atins (~7am). The boat reaches Barreirinhas in time for the midday van.

The Saturday Warning

The main operator (Satur) does NOT run on Saturdays.

If your trip falls on a Saturday:

K-Beça: An alternative that runs on Saturdays
Private boat: Negotiate at the port

Tide Conditions

The crossing along the Rio Preguiças is affected by the tide. At very low tide, boats may delay departure or take alternative routes through the main channel.

The crossing depends on the tide — check the tide tables before you plan, or Talk to us.

Overland Alternative: 4×4 Through the Park

There's an overland 4×4 route through the park that some operators run. It's doable, but the boat is faster, more comfortable, and the scenery is incomparable — we strongly recommend the boat.

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): Flat fee ~R$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
Schedules vary by demand and tide
Saturdays = Satur doesn't run
Some include a taxi to your guesthouse, others don't

A poorly coordinated booking = an unplanned night in Barreirinhas. We keep contacts verified by people who live in Atins — Talk to us.
