Preguicas River Speedboat Tour
The best part of this outing is the changing scenery from Barreirinhas to Caburé. You move from riverbanks and small settlements to the sandy Pequenos Lençóis, then finish where the Preguiças River meets the Atlantic. The speedboat makes the route feel lively, not like a slow sightseeing cruise.
I like the chance to combine several sights in one morning, especially the dune walk and the stop at Mandacaru Lighthouse. I also like the simple price of $35, which includes the hotel-to-port transfer and a Portuguese-speaking guide. The main concern is timing: the Caburé stop can turn into a long lunch break, and pickup instructions need to be confirmed clearly.

Key points to know before booking

- A full river-to-ocean route: The boat travels from Barreirinhas along the Preguiças River to Caburé.
- Four distinct stops: Expect the Pequenos Lençóis, Vassouras, Mandacaru Lighthouse, and Caburé.
- Portuguese guide only: The guide accompanies the group, but no other language is listed.

- Hotel pickup is included: Confirm exactly where and when you will be collected.
- Book friends together: Lunch arrangements may separate people who make different bookings.
From Barreirinhas to the Preguiças River

This tour begins in Barreirinhas, the main access point for many excursions in the Lençóis Maranhenses area. In the morning, a vehicle takes you from your hotel to the port. The transfer is useful because you do not need to arrange your own ride to the river.
The route starts on paved roads in a 4×4 vehicle before you reach the port and board the fast boat. The phrase flying boat suggests speed rather than flight. Expect a brisk ride on the water, with the river providing the main thread between the stops.
The Preguiças River is the reason this trip works so well as a half-day outing. Instead of seeing just one dune area, you get a broad sample of the region. The riverbanks change as you travel, and the boat gives you a moving view of the communities, sand, vegetation, and open water along the way.
You should be ready for a practical, local excursion rather than a polished luxury cruise. The guide speaks Portuguese, and the activity information does not promise interpretation in English, French, Spanish, or any other language. If you do not speak Portuguese, bring a translation app and confirm key instructions before the boat leaves.

Walking across the Pequenos Lençóis

The first major stop is the Pequenos Lençóis, a sandy area that offers a taste of the larger dune country nearby. You will leave the boat and walk among the dunes rather than simply view them from the river.
This is the part I would prioritize if you want a short taste of the region’s famous sand formations. The stop gives you time to see how the pale dunes meet the river setting. It is also the place where comfortable footwear and sun protection matter most. The supplied details do not specify how far you walk, so you should expect an outdoor stop on sand rather than a fixed, paved route.
The dune visit is valuable because the boat ride alone cannot show you the texture and scale of the sand. Once you are on foot, you can look across the rolling shapes, take photographs, and get a clearer sense of why this area draws people to Maranhão.
Do not expect a long independent exploration. This is one stop in a five-hour route, and the group must return to the boat for the next part of the trip. Keep your belongings together and follow the guide’s timing.
Vassouras and the entertaining monkeys

The next stop is the settlement of Vassouras. Here, the river trip takes on a more informal feel. The stop is known within this excursion for encounters with monkeys, and one particularly happy account describes funny monkeys, swimming, and time to relax.
That sounds appealing, but you should keep your expectations sensible. Wildlife encounters are never fully predictable, and the presence of monkeys can create problems when people feed or crowd them. One unhappy account compared the animals to poorly managed wildlife encounters in major national parks. The practical lesson is simple: watch from a respectful distance, follow local instructions, and do not treat the animals as photo props.
Vassouras adds variety to the day. The dunes give you open sand, while this stop puts more attention on local life and the river’s edge. It is also a good chance to stretch your legs after the boat ride.
The guide’s role matters here. The guide can point out natural features and help the group understand what it is seeing, but the service is in Portuguese. If you want explanations, stay close enough to hear them and ask short questions in Portuguese or through a translation tool.
Climbing near Mandacaru Lighthouse
The route continues to Mandacaru Lighthouse, another clear landmark on the river. The lighthouse gives the tour a destination you can recognize, rather than a series of unnamed river views.
The stop is often brief enough to fit neatly into the route, but the value depends on your interest in viewpoints and local landmarks. The activity information does not specify whether access to the top is guaranteed, so do not book this expecting a confirmed lighthouse climb. Think of it as a stop in the Mandacaru area, with the lighthouse as its visual focus.
One account found this stop only so-so, which is a fair warning against overselling it. The lighthouse is not the sole reason to choose the tour. Its real value comes from how it breaks up the journey and gives you a different setting before the final stop at Caburé.
If you are sensitive to heat, this is another point where a hat, water, and sun protection will help. The schedule includes several outdoor stops, and the bright sand and open river can make the day feel hotter than the clock suggests.

Caburé, lunch, and the meeting of river and sea

Caburé is the final destination and the most geographically striking part of the route. Here, the Preguiças River reaches the Atlantic Ocean. You get a clear sense of the region’s two-sided character: river on one side, ocean on the other.
This is also where the schedule becomes less predictable. Lunch is arranged at Caburé, and the stop can last about two and a half hours. That is a large portion of a five-hour tour. For some people, it is welcome downtime for eating, swimming, and relaxing. For others, it feels like too much waiting after the active parts of the route.
I would plan for Caburé as a rest period, not a quick meal. The information does not include lunch in the price, so you should treat food as an extra expense. It also does not name a specific restaurant. The group may be divided among different small restaurants, which can separate you from friends who booked independently.
If staying with your companions matters, make one booking for the whole group. That is a small detail with a real effect on the day. A shared reservation gives you a better chance of being placed together for the lunch portion.
The Caburé pause also explains why some people may feel the tour runs longer than advertised. The listed duration is five hours, but a long lunch stop and local timing can extend the outing. If you have a flight, bus, private transfer, or another activity later that day, leave a generous buffer.
What the $35 price really buys you

At $35 per person, this is an inexpensive way to see several points along the Preguiças River. The price includes transportation from your hotel to the port, the fast boat route, the stops, and a Portuguese-speaking guide.
The strongest value comes from the combination of transport and variety. Arranging separate rides to the port, a boat, and visits to the river stops would likely be more trouble than the price suggests. You are paying for a simple package that connects the major points in one outing.
The price does not appear to include lunch. You should also not assume that drinks, personal purchases, or other food costs are covered. Since Caburé is a long stop, carry enough money for the meal and any small expenses you may have there.
Value depends on how much you enjoy group timing. If you want to see the river, dunes, Vassouras, the lighthouse area, and Caburé without planning each movement yourself, $35 is attractive. If you dislike waiting at restaurants or want long, quiet time at each stop, the same itinerary may feel less efficient.
The rating of 3.8 out of 5 reflects that mixed experience. Safety and general organization received positive marks in one account, while pickup, timing, and booking problems caused serious frustration in others. I would not call this a flawless operation, but the price is low enough that the practical details matter more than luxury touches.
Pickup details deserve a phone call

Hotel pickup is included, but you should confirm the exact meeting point. There has been confusion about whether passengers should wait at the hotel, go directly to the water, or meet at another point near the port.
One person was not collected at all and had to make other plans. That does not prove every pickup will fail, but it is enough reason to take control of the morning. Before the tour date, ask the provider for the pickup time and location in writing. If you are staying somewhere with more than one entrance, specify the exact door or reception area.
The transfer is described as beginning in a 4×4 vehicle and continuing to the port. At the port, you board the speedboat. Make sure you understand this sequence so you are not waiting in the wrong place.
A simple confirmation in Portuguese can help. Ask for the hotel name, pickup time, and port meeting point. Keep the provider’s contact details available on the morning of the tour.
A Portuguese-only guide changes the experience

The live guide speaks Portuguese. This is important, not a footnote. The guide can accompany you and show you natural features, but the amount you understand will depend on your language skills or your ability to translate.
If you speak Portuguese, the tour should be easier to follow and more rewarding. You can ask about the river, the stops, local customs, and the timing at Caburé. If you do not, you can still enjoy the scenery and use the guide’s gestures and group movements, but detailed explanations may be harder to catch.
I would download an offline translation tool before leaving. Save a few useful phrases about lunch, departure time, swimming, and meeting points. The tour has several stops, so knowing where and when to return to the boat is more important than understanding every historical detail.
This is also a good reason to stay near the guide at each stop. The guide is described as practical and discreet, and the strongest positive feedback concerns useful guidance and safe organization. You get more from that service when you are within earshot.
Timing, comfort, and possible snags

The advertised duration is five hours. That is a reasonable length for the route, but you should not treat it as a precise promise. A two-and-a-half-hour lunch break at Caburé can use up half the day, and local departures may not run to the minute.
The boat ride itself should suit you if you like moving water, changing views, and an active schedule. The tour is less suitable if you need a quiet, highly controlled itinerary with fixed departure times.
Bring water, sun protection, and clothing you can wear comfortably outdoors. The supplied information does not specify boat shade, seating, or changing facilities, so it is best to prepare for a warm river excursion without relying on extras.
Swimming and relaxing at Caburé may be possible within the stop, as one account describes swimming there, but the activity details do not set out a formal swim program. Treat swimming as an opportunity rather than a guaranteed feature.
Cancellation is flexible if you act at least 24 hours before departure, with a full refund stated for cancellations within that window. You can also reserve now and pay later. Those terms help if your plans around Barreirinhas are still shifting, but they do not solve same-day pickup or timing issues, so confirmation remains wise.
Who should choose this river trip?
I would recommend this tour to you if you want a low-cost introduction to the Preguiças River and prefer one organized route over several separate arrangements. It suits people who enjoy a mix of boat travel, short walks, local stops, and a relaxed meal at the end.
It is especially useful for a first visit to the area. In five scheduled hours, you get the Pequenos Lençóis, Vassouras, Mandacaru, and Caburé. You will not study any one stop in great depth, but you will see the region’s main contrasts.
Families and groups may like the variety, although everyone should be comfortable with sun, sand, and a potentially long lunch stop. Friends should make one booking if they want to eat together.
I would hesitate to recommend it to you if you need English guiding, exact timing, or dependable door-to-door communication without follow-up. I would also think twice if you want a quiet nature outing with no animal interaction or informal group arrangements.
Should you book the Preguiças River speedboat tour?
Book it if the $35 price, Portuguese guide, and broad selection of stops fit your priorities. The river-to-ocean route is the main attraction, and the combination of dunes, Vassouras, Mandacaru, and Caburé gives you a useful snapshot of the area.
Before paying, confirm the pickup location, ask how long the Caburé lunch stop is expected to last, and make one reservation for everyone in your group. With those details settled, this can be a good-value half-day outing.
Skip it if you need English commentary, a tightly timed five-hour schedule, or a polished service with no uncertainty. The scenery is the reason to go, but the operation requires a little patience and careful communication.
