Twenty to nine on the sand at Boca da Barra, and the man at the association table is writing your name in a spiral notebook with a pen that keeps dying. Behind him a lancha is already loading: a cooler, two crates of water, a stack of life jackets that smell of salt and old sunscreen. He asks how many of you there are, says the low tide today falls at half past twelve, and tells you to be back on this sand at nine. That is the whole booking system for a boat day in Boipeba, and it works.
Boat tours are how you reach the parts of this island your legs will not. Boipeba has no cars and no road out of the village, so the reef at Ponta dos Castelhanos, the fishing hamlet of Cova da Onça on the river side and the neighbouring island of Tinharé are all boat business. This guide is the price list, the timetable and the honest part: which tour earns its money, which one to skip, and the days when the best thing to do with R$250 is nothing at all.
Who sets the prices, and why nobody haggles
The boatmen of Boipeba work through an association that regulates maritime transport around the island and publishes a fixed price per tour. The number quoted to you at the table on Boca da Barra is the number the couple next to you paid, and it is the same number we quote when you ask us to arrange it. There is no bargaining, no commission war, no booking site that undercuts it.
Two consequences are worth knowing before you arrive. First, booking through your pousada costs the same as booking on the sand, so let us do it. Second, the tour price almost never includes food, and lunch is where a cheap day turns into an expensive one.
Prices below were checked through late 2025 and are what we expect to hold for the 2026 season. At the time of writing a US dollar buys roughly five and a half reais, so R$250 is about US$45 and R$120 about US$22. Fuel and season move these numbers. Message us on WhatsApp the week before you travel and we will tell you what the table says that day.

Volta à Ilha: the one to book if you book only one
Duration: about seven hours, sand to sand.
Departs: from Boca da Barra, at the maritime transport association, between nine and ten depending on the tide. The boatman sets the exact hour the evening before.
Returns: between four and half past five in the afternoon.
Price 2026: around R$250 per person, shared boat.
Includes: the lancha, fuel, a licensed boatman and life jackets.
Does not include: lunch, drinks, oysters, snorkel gear on some boats.
The loop goes clockwise around the bottom of the island. First stop is the reef off Moreré, where the boat anchors and you get in the water over the pools. Then Ponta dos Castelhanos, the southern tip, the lighthouse and the wreck story every captain tells slightly differently. Lunch happens at Cova da Onça, a fishing village on the river side of the island, usually at Estrela do Mar, where grilled lobster in butter with pineapple ran R$ 140 to R$ 220 in late 2025, shrimp moqueca R$ 90 to R$ 150 and grilled octopus about R$100, most dishes built for two people. Last stop is a boat moored where the channels meet, the one everyone calls the oyster place, raw oysters around R$25 a dozen and gratinated around R$30, with the sun going down behind Tinharé.
Best tide and hour: a day when low water falls between eleven and two. The pools are the whole point, and they only exist for the couple of hours around the low.
What to bring: cash in small notes for lunch and oysters, reef shoes, a hat, a long-sleeved rash top, reef-safe sunscreen, a dry bag for your phone and about R$150 per person on top of the tour price for food and drinks.
Skip it if: the low tide falls at seven in the morning or six in the evening, because you will spend R$250 to look at water where the pools should be.
Moreré natural pools: half the price, most of the magic
Duration: six to eight hours, depending on the tide window.
Departs: Boca da Barra, morning, hour set by the tide.
Price 2026: around R$120 per person.
Includes: boat and boatman.
Does not include: food, drinks, the floating bar.
This is the short version of the good part. The boat runs down to Moreré, anchors at the reef and leaves you there through the low tide, with the option of the floating bar where you eat seafood snacks at a table standing in waist-deep water. Because the whole trip exists inside the tide window, it lives or dies on the table.
Best tide and hour: the lower the better. Under half a metre and the sandbanks come out dry; near zero and you can walk between the pools. We read the table with you at breakfast, and there is a full explanation in our tides and natural pools guide.
What to bring: your own mask and snorkel if you have one, because boat gear is hit and miss, plus reef shoes. The coral cuts.
Skip it if: you already booked the Volta à Ilha, which stops here anyway.
Ponta dos Castelhanos direct: the tip without the walk
Duration: five to six hours.
Departs: Boca da Barra, morning.
Price 2026: around R$165 per person.
Includes: boat and boatman, a stop at the Moreré pools on the way, lunch stop at Castelhanos.
Does not include: the lunch itself.
Castelhanos is reachable on foot from Bainema in about an hour and a half at low tide, and every year somebody tries it at noon in February and learns something. The boat version costs R$165 and gives you the pools at the tip, which are the clearest water on the island on a good day. Food at the tip is simple: on tour days there are shacks selling fried pastel with lobster or shrimp filling for R$ 140 to R$ 220 and cold beer, on quiet days there may be nothing at all.
Best tide and hour: low water midday. The reef at the tip is exposed and rough, so this is a reef-shoe beach.
Skip it if: the sea is running from the south, which happens often between April and July. Ask the boatman, and believe him when he says no.
Boipeba to Garapuá: a second island for the same price
Duration: four to five hours.
Departs: Boca da Barra, morning.
Price 2026: around R$165 per person.
Includes: boat and boatman.
This one leaves Boipeba entirely. It crosses to Tinharé, the island Morro de São Paulo sits on, stops at Praia do Pontal and ends at Garapuá, a fishing village with its own reef pools a short swim offshore. It is the tour for people staying a week who have already done the loop and want a day that feels like somewhere else.
Best tide and hour: low water again, since the Garapuá pools work exactly like the ones here.
Skip it if: you have three days on the island. Three days is a Volta à Ilha, a beach walking day and a slow one.
Castelhanos baptism dive: the expensive one, and worth asking about
Duration: six to eight hours.
Departs: from Moreré, not from the village.
Price 2026: around R$550 per person.
Includes: boat, licensed instructor, all the gear, and a baptism dive to roughly fourteen metres on the reef.
Does not include: lunch, which happens at Bainema.
You do not need a certification for a baptism dive, only a doctor-free conscience about your ears and a calm sea. Conditions matter more here than on any other tour: the operator will cancel if visibility or swell is wrong, and that cancellation is good news, not bad.
The private lancha to Moreré is a transfer, not a tour
People book this by mistake all the time. A small lancha from Boca da Barra to Moreré carries one to four passengers for about R$250 and takes twenty-five minutes; a larger one takes five to ten for about R$400. That is a transfer with no stops and no snorkelling, useful if you are sleeping a night in Moreré with luggage, or if the tractor has already left and it is getting dark. For everything else, see getting around Boipeba.
What a boat day actually costs
The tour price is about half the day. Budget, per person, in 2026 reais:
- Tour: R$120 to R$250 for the shared tours.
- Lunch at Cova da Onça or Castelhanos: R$85 to R$150 for a dish that feeds two, so R$50 to R$80 each.
- Drinks through the day: R$40 to R$60.
- Oysters at the sunset stop: R$25 to R$30 a dozen.
- Tip for the boatman, entirely optional and always noticed: R$20 to R$30.
Call it R$350 to R$400 per person for the full island loop with everything, roughly US$65 to US$75. We keep a longer list of island prices in the article on what things cost in Boipeba.
Bring cash. Card machines exist on the boats and at Cova da Onça, and they depend on the same mobile signal that drops when the wind turns. Pix works when the signal does. There is no ATM on the island.
When a boat day is not worth it
We would rather you kept the money than spent it on a bad day, so here is the honest list.
- When the low tide sits at dawn or dusk. The pools are the product. No low water in the middle of the day, no pools.
- From April to July, when the sea is up. Rain we can work around; swell we cannot. The boat will bounce for seven hours and the water will be cloudy.
- On your arrival or departure day. The last lancha off the island leaves around four in the afternoon, and the tour gets back between four and half past five. That maths does not work, and we have watched people learn it the hard way. See how to get here.
- With a child under about four. Seven hours, no shade for long stretches, no toilet on most boats.
- If you get seasick. Take the Moreré pools tour instead: less time on the water, same reef.
How to book yours
Ask us the day you check in. We message the association or the boatman we work with, tell them how many you are, and the hour comes back that evening with the tide. In high season, from late December through Carnival, book two or three days ahead, because the good boats fill. In low season you can decide at breakfast.
If we say wait a day, wait a day. The tide table does not negotiate, and a Tuesday loop with a midday low beats a Monday loop with a four o'clock low every time.
Frequently asked questions
How much does the Boipeba island boat tour cost in 2026? Around R$250 per person for the full Volta à Ilha, a fixed price set by the boatmen's association. Lunch, drinks and oysters are not included, so budget another R$100 to R$150 per person.
Do I need to book the boat tour in advance? In low season you can book the evening before, either at the association table on Boca da Barra or through us. From late December to Carnival, book two or three days ahead.
Which Boipeba boat tour is best if I only do one? The Volta à Ilha. It covers the Moreré pools, Ponta dos Castelhanos, lunch at Cova da Onça and the oyster stop at sunset in one seven-hour day, around R$250 per person.
Does the boat tour depend on the tide? Completely. The natural pools only appear for about two hours around low water, and departure shifts between nine and ten to match it. Ask us to check the tide table before you fix a date, or read our FAQ.
Pick your days by the tide, not by the calendar. See the flats, tell us your dates, and we will tell you which morning the pools will be there.
