Our review · LENÇÓIS MARANHENSES TOURS
Preguicas River Speedboat Tour
The best part of this outing is the changing view from the water. You leave Barreirinhas by vehicle, board a fast boat, and follow the Preguiças River past dunes, small settlements, palms, and wide sandy shores until river and Atlantic meet at Caburé. The ride gives you a useful taste of the Lençóis Maranhenses area without spending a full day on a long 4×4 route.
I like the easy mix of river scenery and short stops, especially Pequenos Lençóis and the view from Mandacaru Lighthouse. I also like the price: at $35 per person, hotel-to-port transport, a guide, boat travel, and several stops can make this a strong half-day value. The main concern is organization, since pickup instructions and the long lunch stop have caused trouble for some people.
Key points to know before booking

- The boat is the main event: You follow the Preguiças River by speedboat, with broad views of dunes and riverbank villages.
- Pequenos Lençóis comes early: You can get off and walk across smaller dunes rather than only viewing them from the boat.
- Vassouras adds a wildlife stop: Monkeys may be present, but feeding or crowding them can make the visit unpleasant.
- Mandacaru Lighthouse is a brief change of pace: The stop offers a higher viewpoint, though some people find the stay there underwhelming.
- Caburé is the longest stop: Lunch takes place where the Preguiças River meets the Atlantic, but the break may run much longer than expected.
- Portuguese is the tour language: The guide accompanies you, but no English, French, Italian, German, or Russian service is listed.
From Barreirinhas to the Preguiças River

Your morning begins with pickup from your hotel in Barreirinhas. The stated plan describes a road transfer in a 4×4 vehicle to the port, where you board the speedboat. This first step matters more than it may sound, since clear pickup instructions are important in Barreirinhas, where the riverfront and hotel areas can involve different meeting points.
The outing is sold as a five-hour experience. That makes it a good fit if you want to keep part of the day free for another activity, rest, or a separate visit in town. Still, you should treat the five-hour figure as an estimate rather than a guarantee. A long lunch break has made the outing run well beyond the planned length for at least one booking, and one person reported a serious pickup failure.
Before leaving, confirm exactly where you will be collected. The included service is hotel-to-port transport, but one person understood that the boat would pick them up directly at the water. That confusion led to a missed pickup. I would ask the operator for the exact meeting point, pickup time, and whether you should wait at your hotel entrance or at a river access point.

A fast boat through changing river scenery

Once you reach the port, the experience shifts from road travel to water travel. The speedboat carries you along the Preguiças River, the main waterway through this part of Maranhão. You will see the banks change as the boat moves toward the coast, from town edges to sandy stretches, vegetation, dune fields, and small riverside settlements.
The speed makes it possible to cover several stops in a half day. It also gives the trip a lively feel, though the ride may be less restful than a slow boat. You should expect an open-air outing shaped by sun, wind, spray, and frequent boarding and landing.
The guide speaks Portuguese. The guide’s role includes accompanying the group and pointing out features of the natural setting. One of the strongest parts of the outing, based on the available feedback, is the way the guide identifies things along the river and helps explain what you are seeing. If you do not speak Portuguese, you may still enjoy the scenery and stops, but you should not expect a full explanation in another language.
Walking among the dunes at Pequenos Lençóis

Pequenos Lençóis is one of the most appealing stops because it lets you leave the boat and walk on the dunes. The name means Little Lençóis, a smaller dune area related in character to the famous Lençóis Maranhenses region.
This stop gives you something the boat ride cannot: a chance to feel the sand underfoot and see how the dunes rise beside the river. You can walk, take in the open views, and get a closer look at the contrast between pale sand and dark water. The stop is also useful for breaking up the ride, especially if you prefer an active outing rather than several hours seated in a boat.
The supplied details do not state how long the walk lasts or whether a set route is used. Plan for a simple dune visit, not a long trek. Sand walking can be tiring, so light clothing, water, sun protection, and footwear that handles loose sand will make this stop easier.
The river remains the thread connecting every part of the day. At Pequenos Lençóis, you see the area from land. From the boat, you then regain the broad view and continue toward the settlements farther downstream.
Vassouras and the monkey problem

Vassouras is another stop along the river. It is associated with monkeys, and you may see them near the visitor area. This can be a memorable moment, particularly if you enjoy wildlife and want something different from dunes and boat views.
But this is also the stop that calls for the most care. A poor interaction with wild animals can quickly turn a pleasant stop into a stressful one. One account described the monkeys as aggressive and compared the scene to old-fashioned wildlife encounters where people crowd animals and encourage them to approach. That is a useful warning for you: enjoy the animals from a sensible distance, and do not treat them as performers.
The available information does not state whether food is provided for the monkeys or whether feeding is formally encouraged. For that reason, do not assume you should offer them anything. Keep your belongings secure and follow the guide’s instructions. The stop may be fun, but it is not the reason I would book the whole tour. The river and dune scenery are the more dependable attractions.

Mandacaru Lighthouse and the second pause

The route continues to Mandacaru Lighthouse. This stop adds a different kind of view, since a lighthouse gives you a chance to look over the surrounding area from higher ground. After seeing the river at water level and the dunes on foot, a raised viewpoint can help you understand the shape of the coast and the nearby settlement.
The lighthouse stop has received mixed reactions. Some people find it worthwhile, while others consider it only an average pause. That difference likely comes down to expectations. If you want a major monument or a long cultural visit, this will probably feel modest. If you enjoy short stops that break up the boat trip and offer another angle on the area, it fits the day well.
The details provided do not confirm whether access to the top is always available, how many steps there are, or how long the group stays. The tour description simply identifies the Farol de Mandacaru as a stop. You should therefore see it as an added viewpoint rather than the central feature of the outing.
Caburé, lunch, and the meeting of river and sea

Caburé is the final destination described in the route. It is the spot where the Preguiças River meets the Atlantic Ocean, giving the day its most dramatic geographic moment. You can see the river’s calm flow give way to the coast, with sand and open water shaping the surroundings.
This is also where the tour slows down. Lunch takes place at Caburé, and the stated schedule may allow a lengthy break. A two-and-a-half-hour lunch pause was considered far too long by one person and made the day run much later than expected. If you are hoping for a tightly timed five-hour trip, this is the part to watch.
The lunch cost is not listed as included. The tour includes hotel-to-port transfer and a Portuguese-speaking guide, but no meal is named among the inclusions. Plan to pay separately for food unless the operator tells you otherwise.
There is also a practical group issue at Caburé. The boat operator may divide people among different small restaurants. If you are traveling with friends and want to eat together, make one booking for the whole group. Separate reservations may lead to separate lunch assignments, even if you arrived together.
Caburé’s value is not only the meal. It gives you time to stop rushing, sit near the meeting point of river and ocean, and enjoy the coast. Still, the length of the break should match your style. I would welcome a proper pause after a hot boat ride, but I would not want an unplanned two-and-a-half-hour wait if I had another activity booked later.
What $35 buys you
At $35 per person, this is a low-cost way to see several parts of the Preguiças River corridor. You get transport from your hotel to the port, a speedboat route, a guide, dune access at Pequenos Lençóis, stops at Vassouras and Mandacaru, and time at Caburé.
The price looks especially fair if you value variety. Instead of paying separately for a river transfer, a dune visit, and a coastal stop, you combine them in one outing. The price is also helpful for people who want an introduction to the area before deciding which places deserve more time.
The value falls if the pickup goes wrong or if the long lunch disrupts your plans. A missed tour is not a bargain, even at a low price. The experience also depends on the quality of local coordination, so the practical details matter as much as the advertised route.
The overall rating is 3.8 out of 5 from 14 ratings. That points to an experience with genuine strengths but uneven delivery. Safety and basic organization received positive comments, and the guide was described as practical and discreetly friendly. The weaker points were pickup communication, the extended final stop, a booking payment error, and one complete missed pickup.
Who will enjoy this boat trip?

I would choose this outing if you want to see the Preguiças River, Pequenos Lençóis, and Caburé in one compact day. It suits people who like a mix of movement and short visits, rather than a single long stay in one place.
Families and couples may like the simple route and the chance to see dunes, monkeys, a lighthouse, and the Atlantic in one trip. The price also makes it approachable for budget-conscious visitors. You should be comfortable with a fast boat, sun, sand, and an itinerary that may not run to the minute.
This is less suitable if you need English-language guiding, strict timing, or a carefully managed restaurant arrangement. It may also disappoint you if you want a deep cultural program at each stop. The Portuguese guide can add useful local context, but the only listed tour language is Portuguese.
Groups should pay special attention to booking. Make a single reservation if you want to remain together at lunch. Solo bookers and couples have less to coordinate, but they should still confirm pickup details before the morning of the trip.
Booking details worth checking

Cancellation is flexible: you can cancel up to 24 hours before the activity for a full refund. You can also reserve now and pay later, which helps if your Barreirinhas schedule is still shifting.
The listed duration is five hours, and starting times depend on availability. Since the lunch stop can stretch and pickup arrangements have caused confusion, ask the provider to confirm the actual return time. That small step can protect a later reservation.
The tour is provided by Tour by Foot. The listed guide service is in Portuguese, and no individual guide name is supplied. Do not assume that another language will be available unless the operator confirms it directly.
Should you book the Preguiças River Speedboat Tour?
I would book it if you want an affordable first look at the Preguiças River and nearby coast, and you are happy to accept a relaxed schedule. The combination of speedboat views, dune walking, Vassouras, Mandacaru, and Caburé gives you a lot for $35.
I would pause before booking if your day depends on a precise finish time. Confirm the pickup point, ask how long lunch normally lasts, and make one reservation for your entire group. With those details settled, this can be a lively and good-value introduction to the river country around Barreirinhas.
