Caburé – Boat tour on the Rio Preguiças
The best part of this day is the change of scenery: you race down the Rio Preguiças, pass mangroves and sandy riverbanks, then reach a beach where the Atlantic lies on one side and the river on the other. It is a fine way to see how river life and coastal life meet in northeastern Brazil.
I like the stop at Mandacaru’s lighthouse, where a climb gives you wide views of Caburé, Atins, the beaches, and the village below. I also like the easy pace in Caburé, with time for lunch, a hammock, or a swim. The main caution is that this is a popular, full-day boat outing, and one past departure suffered serious boat trouble and missed stops.
Key points
- 08:00 departure from Barreirinhas: Plan on a full seven hours, with pickup at your hotel or directly from the river if your lodging has river access.
- Vassouras and the small Lençóis: The first stop introduces sandy terrain and river-country scenery before the boat continues downstream.
- Mandacaru lighthouse: Climb for a panoramic view of Caburé, Atins, the beaches, and Mandacaru village.
- Caburé’s two-water setting: Spend several hours between the Atlantic Ocean and the Rio Preguiças, with swimming possible on either side.
- Portuguese-led outing: English and German guides can be arranged for an additional cost.
- Lunch is separate: The tour includes water and a small snack, but you pay separately for lunch and other drinks.
A morning departure from Barreirinhas

This seven-hour trip starts at 8:00 in the morning, so it takes up most of your day. That is useful if you want one organized outing that combines river scenery, mangroves, a lighthouse, and beach time without arranging separate transport.
Pickup is included. You may be collected by a transfer service at your hotel, or directly by boat if your accommodation connects to the river. That second option is especially convenient, since you can begin the trip without first making your way to a separate landing stage.
The ride is by speedboat on the Rio Preguiças. The boat makes the journey feel active rather than passive, but the open-air setting also means strong sun and wind. Bring a hat, sunscreen, swimwear, and beach clothing. One liter of water and a small snack are included, but I would not treat that as a full day’s food supply.
The guide speaks Portuguese. If you need explanations in English or German, request that option when booking and expect an added charge. This matters more here than on a simple transfer because the stops are part of the value. You will get more from the villages, river, and lighthouse if you can follow the guide’s explanations.

Vassouras and the small Lençóis

The first stop is Vassouras, a settlement associated with the small Lençóis. The name points to the sandy scenery found around the river, with low dunes and open, pale ground rather than a city-style attraction.
This is a short introduction to the region’s character. The Rio Preguiças is not just a route between towns. It links freshwater, sandy areas, mangroves, fishing communities, and the coast. Vassouras helps you see that connection early in the day.
I would keep your expectations in check. The stop is not presented as a long walk or a major sightseeing site. It works best as a brief chance to step off the boat, look around, and get a first feel for the sandy interior near the river.
That short stop also breaks up the boat ride. On a seven-hour outing, regular pauses matter. You can stretch your legs, take photos, and return to the boat ready for the next section of the river.
The Rio Preguiças by speedboat

The boat ride is the backbone of the experience. You travel along the Rio Preguiças through a setting shaped by both water and sand. Mangroves add a different texture to the route, while the riverbanks give way to the coastal villages farther along.
This is a good choice for you if the journey itself matters as much as the destinations. The boat lets you see the region from the water, and the route offers a practical view of how communities such as Mandacaru and Caburé are connected.
The ride is also the part most affected by conditions and equipment. A serious problem was reported on one departure, with several boats breaking down, being towed, and causing long delays. That outing missed planned stops, and the agency agreed to a refund. It appears to have been an exception rather than the normal pattern, since other departures were praised for smooth service and friendly staff, but it is still a fair reason to keep your plans flexible.
Do not schedule a tight connection or an important evening activity after this tour. The stated duration is seven hours, and mechanical trouble or delays could push the return later.
Mandacaru lighthouse and the best view of the day

The village of Mandacaru is the most rewarding sightseeing stop. Here, you can climb the lighthouse for a broad view over the village, the beaches of Caburé and Atins, and the surrounding coastal area.
The lighthouse stop is short, but the view gives the whole route a useful sense of place. From the river, the region can feel like a series of separate stops. From above, you see how the beaches, water channels, village, and sandy ground fit together.
Allow a little effort for the climb. The tour is not suitable for wheelchair users, and the lighthouse visit involves access that may be difficult for anyone with limited mobility. No special accessibility support is described, so ask before booking if stairs or uneven ground are a concern.
This is also the clearest photo stop. You can look back toward the river, out toward the coast, and down over Mandacaru. The view is one reason I would choose this boat trip over an outing that only takes you directly to a beach.
Keep your hat and sunscreen handy. The lookout is exposed, and the sun can be strong in the morning.

Caburé between river and Atlantic
After Mandacaru, the boat continues to Caburé for the longest pause of the day. The village and beach sit between the Rio Preguiças and the Atlantic Ocean, giving you two very different places to spend your free time.
You can swim in the ocean on one side of the beach or in the river on the other. That choice is the unusual feature here. If the sea feels too rough or the river looks more inviting, you are not limited to one type of water.
Caburé also offers the least hurried part of the outing. You have several hours for lunch, a hammock, or a quiet break by the water. This is not a packed schedule where you rush off the beach after a quick photograph. The stop gives you time to enjoy the setting at your own speed.
Lunch is not included. You pay for the meal and drinks separately, so carry enough money for that expense. The tour includes one liter of water and a small snack, which helps during the ride but does not replace lunch.
A seafood meal with a water view may be part of your Caburé experience, but the specific restaurant and menu are not stated. The important practical point is to budget separately for food. One especially positive account described the lunch break as tasty and enjoyed with a view of the water, while another singled out the combination of good food and a pleasant stop.
The hammock option makes Caburé suitable for mixed groups. One person can swim, another can eat, and someone else can simply rest. If you are traveling alone, keep in mind that several hours of free time may feel less rewarding than it does for a couple or group, especially if you have already covered the same river route while heading to Atins.
What the experience is worth at $60

At $60 per person, the price is reasonable if you want several experiences in one day: a guided river trip, two stops before the beach, lighthouse access, and free time at Caburé. The value comes from the transport and the route as much as from any single attraction.
You are paying for a boat, hotel or riverside pickup, a local guide, water, and a snack. You are not paying for lunch, drinks, or a German or English-speaking guide. Add those costs before comparing this outing with an independent boat arrangement.
The tour is a stronger buy for a first visit to the area. You see the river, mangroves, sandy surroundings, fishing villages, a lighthouse, and the coast in one organized day. If you have already traveled the same river route to Atins, the novelty may be lower. One experienced solo visitor found the repeated route less special, while still rating the lighthouse and food highly.
The price also buys convenience. You do not need to arrange separate transport between Barreirinhas, Vassouras, Mandacaru, and Caburé. That is useful in a region where river travel is central to getting around.
Language, service, and the human side of the trip

The standard guide language is Portuguese. That is fine if you understand Portuguese, but it can limit the experience if you do not. You can book an English-speaking or German-speaking guide for an additional fee, which is worth considering if you want context at the villages and lighthouse rather than only help with timing.
Service seems to depend partly on the crew assigned that day. One especially warm account praised a young staff member for being friendly and helpful throughout the trip. Other positive comments described the staff as kind and attentive, and the operator LencoisPrime EcoTour received praise for its service.
That personal attention matters on a boat outing. Staff help with boarding, timing, stops, and the transition between river and beach. Still, the mechanical problem reported on one departure shows why you should not assume every day will run perfectly.
The best approach is to enjoy the trip without building an overly tight schedule around it. If everything runs normally, the seven-hour plan gives you a well-shaped day. If a boat problem occurs, flexibility will make the experience less stressful.
Who will enjoy this boat trip most

I would recommend it to you if you want a broad introduction to the Rio Preguiças and the coast near Barreirinhas. It suits people who like changing scenery, short sightseeing stops, swimming, and unhurried beach time.
It is also a good match for couples and families who want different options at the final stop. One person can rest in a hammock while another swims in the river or ocean. The lighthouse adds a clear sightseeing goal, so the day is not only a long ride followed by lunch.
You may want to skip it if you have already traveled the same route to Atins and are looking for something completely new. The river trip can feel repetitive on a second pass, especially if your main interest is a demanding nature excursion rather than a relaxed boat day.
It is not suitable for wheelchair users. Consider the lighthouse access and the boat transfer carefully if you have limited mobility, since no wheelchair support is provided.
What to bring for a comfortable day
Pack light, but cover the basics:
- Sun hat
- Sunscreen
- Swimwear
- Beachwear
- Extra money for lunch and drinks
The supplied water and snack are useful, but you should still plan around a proper meal at Caburé. Alcohol and drugs are not allowed, and littering is prohibited. Keep personal items secure on the boat and protect anything sensitive from spray or sand.
The tour combines water, sun, and open beach. I would wear clothing that dries easily and keep your phone protected when you are not taking photos. These are simple precautions, but they make the long day more comfortable.
Should you book the Rio Preguiças tour?
Book it if you want a convenient, good-value day that combines river travel and Atlantic beach time. The lighthouse in Mandacaru is the visual highlight, while Caburé gives you the freedom to swim, eat, or rest rather than follow a rigid schedule.
Think twice if you have already made the same boat journey to Atins, dislike long outings, or need guaranteed timing. Ask about an English or German guide if language matters, budget separately for lunch, and leave room in your schedule in case the boat runs late.
For a first visit to the area, I would choose this tour for its variety. You get a real sense of the water routes around Barreirinhas, not just a quick stop at one beach.
