Boat trips from Boipeba: every route, price and departure time

It is ten past seven in the morning and there are eleven people standing on the sand at Boca da Barra in front of a wooden shed with the words Associação de Transporte Marítimo painted on it. Nobody is buying a ticket yet. Everybody is waiting for one man to come out and say what time low tide falls today, because that is the sentence that decides where the boats go and when they leave.

Every boat trip from Boipeba is sold with the same phrase attached: a combinar de acordo com a maré, to be agreed according to the tide. Learn that and half of this article is already in your head. Here is the other half: which trips actually exist, what they cost in 2026, how long they take, what is and is not included, and how to pick one without wasting a day.

The trips that exist, in one table

All of them leave from the beach at Boca da Barra, a few minutes' walk from our flats. Prices below are per person on a collective boat, as published by operators selling Boipeba trips in 2026. They are standardised by the local boatmen's cooperative, which is why you will hear the same numbers from different people; they are not a government tariff, and they move with fuel.

For scale: the round-island trip was around R$100 in 2019 and R$150 to R$200 in 2023. R$250 is what it costs now. Confirm the day before, because we ask the boatmen and they tell us the truth about that week.

Volta à Ilha: the long one

This is the trip people mean when they say "the boat tour". It leaves Boca da Barra between 9:00 and 9:30 depending on the tide and gets back between 16:00 and 18:00, and it goes all the way around Ilha de Boipeba.

The order of stops changes with the tide, but the standard run is: the natural pools at Moreré, a look at Bainema from the water, the beach at Ponta dos Castelhanos and the pools inside its reef, lunch at Cova da Onça on the river side, and then the mangrove estuary of the Rio do Inferno up to the oyster farms at Canavieiras and Tapuias, sold as the Portal das Ostras, where a floating bar serves oysters raw, grilled and gratinated. The last leg is usually timed for the light.

Two honest warnings. First, seven hours is a long time in a boat with an engine and no shade to speak of. Second, operators disagree in writing about whether lunch is included: one sells it as included, another lists it as an extra. Budget R$100 to R$150 per person for lunch, drinks and oysters, and ask the question out loud when you book.

Castelhanos direct, Moreré, Garapuá: the short ones

Ponta dos Castelhanos direct, R$200 and five to six hours, runs the east coast, stops to swim at the Moreré pools and again at Castelhanos, and comes back. It needs eight passengers to run, which in low season means either waiting for a group or paying for the empty seats. Full detail is in the Castelhanos guide.

Moreré and the natural pools, R$125, is the cheapest boat on the island and the one most tied to the tide, because the pools only exist while the reef is exposed. It needs six passengers. There is a floating raft at the pools selling drinks and seafood snacks, paid separately. How to read the tide table for it is in the Moreré tide guide.

Garapuá is the one nobody expects. It is not on Boipeba at all: it is a fishing village on the south of Tinharé, the next island, and the boat runs up past the coconut groves of Fazenda Pontal and along Praia do Pontal to get there. R$200, four to five hours, minimum eight people, and its natural pools also only form at low tide. Good choice on a second visit, when you have already done Castelhanos.

Diving. There is a boat dive trip at Castelhanos, around R$700 per person for six to eight hours, leaving from the beach at Moreré rather than from the village, with instructor and equipment included and sites at 10 to 14 metres. Certification required; discovery dives are offered.

Cairu and the mangrove: what is actually sold, and what is not

Here is the thing the guidebooks get wrong. There is no standalone boat tour from Boipeba to Cairu. The mangrove and the oyster farms are a leg of the Volta à Ilha, not a product of their own.

If you want to see the town of Cairu itself, with the Franciscan convent and church of Santo Antônio, whose foundation stone was laid in 1654 and which has been federally listed since 1941, the way to do it is not a tour. It is the scheduled boat. Cairu is about twenty minutes from Boipeba and both the Valença line and the Graciosa line call there. You get off, you walk up, you visit the convent for a small fee reported at a couple of reais, and you catch a later boat back. Ask us to work out the times with you the night before, because getting the return wrong means a long afternoon in Cairu.

If what you want is the mangrove itself rather than the town, the better product is a paddle. Kayak, canoe and stand-up paddle trips leave from Boca da Barra into the Rio do Inferno: about R$130 for two hours, R$155 for a three-hour sunset and bioluminescence version, and around R$215 for a night paddle into the mangrove tunnel. Silent, close to the water, and nothing like the same thing seen from a boat with an engine.

Day trip to Morro de São Paulo

Yes, it is possible, and no, there is no regular collective boat doing it directly. Three ways:

1. 4x4 and boat via Fazenda Pontal, run by Expresso Madalena and sold as a transfer, about R$150 per person and roughly 1h10 door to door. Departures Boipeba to Morro at 09:00, 13:00 and 18:00, and Morro to Boipeba at 08:00, 12:00 and 17:00. This is the sane way to do a day trip: out on the nine, back on the five.
2. Private speedboat, about fifty minutes, priced per boat: roughly R$1,040 for one to four people one way in 2026, more for larger groups, with a surcharge after 18:00. Fast, expensive, worth it for a group with luggage.
3. Two scheduled boats via Valença, which is the cheapest and, for a day trip, the worst idea on this page. It is a long day of waiting on two piers.

Whether you should go at all is a separate question. Short version: go if you want to see the contrast between the two islands, not if you want a beach day.

Whale season

Humpbacks pass this coast roughly from July or August to October or November. Whale-watching boats run from Boca da Barra and from Praia do Outeiro, four to five hours, quoted between R$250 and R$320 per person by different operators in 2026. It is the one reason to be pleased about coming in the cooler months. There are no guarantees and honest operators say so.

What to take, and what the price does not include

• Cash in reais. There is no reliable cash machine on the island, and the card machines on the boats and at the beach restaurants depend on the same phone signal that drops when it rains. Bring R$150 to R$200 per person for a full-day trip.
• Reef shoes. The pools have coral rubble on the bottom and coral cuts are the most common injury here.
• A long-sleeved rash guard and a hat that ties on. Seven hours of reflected sun is not the same as an afternoon on the sand.
• A dry bag. Spray comes over the bow, and your phone lives on the deck.
• Seasickness tablets, taken an hour before boarding. Not on the boat. An hour before.
• Water. Boats carry a cooler, sometimes.

What the price does not include, almost anywhere: lunch, drinks, the oyster tasting, and anything you buy on a floating bar.

The tide, the wind, and the days not to go

The tide decides whether the pools exist. Around the new moon and the full moon, low tide falls in the morning, which is exactly when you want it, and those are the weeks to book if the natural pools are the reason you came.

The wind decides whether the ride is pleasant. The east coast is open ocean and on a strong southeast day the stretch between Bainema and Castelhanos will make somebody on your boat unwell. The boatmen know at seven in the morning. If they tell you it is a bad day, believe them and go the day after.

Rain: April and May are the wettest months on this coast, June and July are wet, and January through March and August through December are the drier stretch. Travel sites will tell you the sea is calm from August to March. That matches the rainfall data and it matches what we see, but nobody publishes sea-state statistics for this stretch of coast, so treat it as experience rather than as a measurement.

A word on safety, because it changed recently

After a collision between two boats near Morro de São Paulo in April 2025, the Capitania dos Portos in Bahia stepped up inspections across the Cairu archipelago, seizing vessels and checking life jackets, fire extinguishers and navigation lights. In June 2026 the state prosecutor's office opened a programme to map and standardise piers, operators, routes and fares across the tourist coast, Cairu included.

What that means for you is simple and takes ten seconds. Before the engine starts, count the life jackets and check there is one for every person, children included. If there is not, get off. Any decent boatman here will respect you for asking, and the good ones will have already handed them out.

Which boat trip should I do if I only have one day? If the low tide falls in the morning, Moreré and the natural pools. If it does not, Castelhanos direct. Leave the seven-hour round-island trip for a longer stay.

Is lunch included in the Volta à Ilha? Operators publish different answers, so ask when you book. Budget R$100 to R$150 per person for lunch, drinks and the oyster stop.

Can I do a day trip from Boipeba to Morro de São Paulo? Yes, most easily on the 4x4-and-boat transfer at around R$150 per person, out at 09:00 and back at 17:00. There is no direct scheduled collective boat between the two islands.

Do I need to book boat trips in advance? Not usually, but ask on the afternoon you arrive rather than the night before you want to go, because the short trips need a minimum group and the peak weeks sell out.

Tell us your dates and we will look at the tide table with you before you book anything. Start with how to get here, then the flats, two minutes from the beach where every one of these boats leaves.
