Dunes, lagoons, and a long walk in one day. This guided trek in Lençóis Maranhenses takes you from Lagoa Azul to Lagoa Bonita, with 4×4 transport from Barreirinhas and time to enjoy the sunset.

I love the fact that the day is built around real walking, not constant switching between vehicles and stops. With a local guide at your side, you get help staying oriented through the dunes and lagoons.

The one real catch is the effort: it’s a 12-hour outing with a 12 km hike, so it’s not for you if you’re dealing with back problems, mobility limits, or low fitness.

Key things I’d circle before you go

• 12 km trek from Lagoa Azul to Lagoa Bonita across sandy terrain and lagoon views
• 9:00 am departure from Barreirinhas in a 4×4 vehicle
• Lunch stop at Lagoa Bonita at a local restaurant (food and drinks are listed as not included)
• Time after lunch until sunset where you’re trekking
• Portuguese-speaking guide on the walk
• No alcohol or drugs, plus you’ll want sunglasses, a cap, and real walking shoes

A 12 km trek that actually feels like the park

Lençóis Maranhenses works best when you’re on foot. This day trip is set up for that: you leave Barreirinhas at 9 am, ride out by 4×4, and then start walking under the dunes as you work your way toward Lagoa Bonita. You’re not just seeing water from afar—you’re moving through the same natural system that shapes these dunes and seasonal lagoons.

What I like most is the pacing. The day isn’t packed with extra detours. You get a strong chunk of walking—12 km—and then time to linger at Lagoa Bonita before heading back. That structure helps you feel the place in a practical way: sand under your feet, lagoon moments as they appear, and a real finish with sunset time.

The only thing to weigh is how physical the day is. This isn’t a stroll. The route is long enough that low fitness, serious back issues, or reduced mobility can turn the experience into a chore instead of a highlight.

Getting to the dunes: why the 4×4 ride from Barreirinhas matters

Your day starts with pickup from your hotel in Barreirinhas, and you travel out in a 4×4 vehicle. That detail is more important than it sounds. Lençóis Maranhenses terrain can be rough and sandy in ways that don’t work for a standard ride, so the vehicle choice helps you get where the trek begins without wasting time.

This also shapes the mental rhythm of the trip. You’ll arrive, you’ll feel the dunes, and then you’ll step into the hike without a long, complicated transfer. When the day is already a 12-hour commitment, less logistical friction is a win.

Tip: since pickup depends on your hotel name, make sure you share it clearly when you book. It’s the simplest way to avoid last-minute confusion on a morning departure.

Walking the Lagoa Azul to Lagoa Bonita route

The heart of the day is the 12 km trek from Lagoa Azul to Lagoa Bonita. The best way to think about it: you’re crossing a dune-and-lagoon world where the scenery changes as your elevation and angle shift. As you go, you pass several lagoons and you get strong visual contrasts—sand underfoot, water in pockets, and big open views when the dunes allow it.

What you’ll likely feel on the trail

Even without guessing any technical details, 12 km in dune country is a workout. Sand can slow your stride, and the sun exposure can add up. This tour sets you up with an expectation of effort, not a casual walk, which is why it excludes people with low fitness and also lists limits for back problems and mobility impairments.

The guide’s role (and why it’s worth having one)

You have a live tour guide who speaks Portuguese. On a route like this, the guide matters because it’s not just about distance—it’s about timing, staying on the right path, and keeping you moving in a way that fits the day’s schedule. If you’re comfortable with Portuguese, you’ll get more out of the explanations as you walk. If not, you can still follow along, but plan for less commentary.

Footwear is not optional

The tour specifically calls out nice shoes. I treat that as serious advice. In dune terrain, comfortable walking shoes are what lets you enjoy the trek instead of focusing on sore feet. If you show up in shoes with little traction or no support, the day will feel longer than it is.

Lagoa Bonita lunch stop: fuel plus a chance to breathe

After your hike, you reach Lagoa Bonita. The day includes lunch at a local restaurant there, and this is where the trip changes gears: you switch from sand effort to eating, rehydrating, and resetting your legs.

One practical thing to double-check: the activity notes say food and drinks are not included. That doesn’t mean you won’t have lunch—it means you may need to pay for what you eat and drink. Since the day is already focused on a guided hike and transport, I’d treat lunch as a scheduled stop, but still verify what’s covered when you book.

What makes the lunch stop valuable is the location. Lagoa Bonita isn’t just a waypoint; it’s a place you reach and then get time in. That gives you a more complete experience than a quick snack-and-go.

Sunset time: the payoff after the walking

After lunch, you get time until sunset at Lagoa Bonita. This is the part I’d call the emotional payoff. You’ve already spent hours moving through the dune-and-lagoon scenery, and sunset time gives you a slower pace to enjoy how the light changes the water and sand.

Practical angle: sunset timing means you should plan to stick with the schedule. If you wander too far off the group or spend too much time stretching right away, you can end up rushing the last part of the day. Keep your energy for the finish.

Returning to Barreirinhas in the 4×4 vehicle

Once sunset time is done, you head back to Barreirinhas by 4×4. The point here is that the trip is structured as a full day: transport out, 12 km walk, lunch, sunset time, transport back. It’s not a half-day activity, so start the day well-prepared and don’t count on being able to improvise comfort later.

Also, if your hotel pickup is tight, make sure you know exactly where you’ll be collected. The departure is set for 9 am, and you’ll want to avoid any morning delays that can throw off the day.

Price ($261): what you’re paying for, and why it can be worth it

At $261 per person for a 12-hour guided trekking day, you’re paying for three core things:

• Guiding (a live Portuguese-speaking guide on the hike)
• Transport from Barreirinhas via 4×4
• A full-day structure that includes the route from Lagoa Azul to Lagoa Bonita, plus lunch and sunset time

The “not included” part is important for value math: food and drinks aren’t included. That’s a real budget item. Still, the way the day is designed—long walk, time at Lagoa Bonita, and the logistics handled for you—can make it feel worth it if your goal is to experience Lençóis Maranhenses on foot rather than piecemeal.

My advice: if you’re the type who enjoys committing to a hike and you’re comfortable planning around meals you pay for, the price feels reasonable for what you actually get. If you’re hoping for a lighter day or you want lots of included meals and drinks, you might find the cost-to-comfort ratio less appealing.

Who this tour suits (and who should choose something easier)

This trek is clearly aimed at active travelers. It’s listed as not suitable for:

• children under 12
• people with back problems
• people with mobility impairments
• people over 331 lbs (150 kg)
• people with low level of fitness

That list is your reality check. If you’re on the edge fitness-wise, don’t romanticize it. 12 km plus dune conditions is long enough that your body will call the shots.

Best fit

You’ll likely love this if:

• you want a guided, no-nonsense trek through Lençóis Maranhenses rather than a quick sightseeing loop
• you enjoy walking and want the scenery to unfold as you move
• you want a day with a clear arc—walk, lunch, sunset finish

Not the best fit

You might want a different option if you:

• need frequent stops with minimal walking
• have pain limitations that worsen with longer durations
• rely on mobility supports and can’t manage sandy terrain for an extended period

What to bring: the sun and the sand are the real bosses

The tour calls out a few items directly: sunglasses, a cap, and nice shoes. Take those seriously. The dunes put you in open sun for long stretches, and sandy footing punishes footwear.

Beyond that, you’ll want to come in ready for a long 12-hour outing. If you plan your day like a hike—hydration habits, snack planning if you’re paying for lunch/extra drinks, and comfortable socks—you’ll enjoy it more.

Also note the rules: no alcohol or drugs. It’s worth remembering because it keeps the day safer and more focused, especially when you’re out walking for hours.

Should you book this Lagoa Azul to Lagoa Bonita day trek?

Book it if your top goal is to feel Lençóis Maranhenses on foot. This itinerary is built around a real hiking distance (12 km) with a structured day: 4×4 from Barreirinhas, a guided route from Lagoa Azul to Lagoa Bonita, a lunch stop, and time until sunset. If you’re fit enough for a full day outdoors, you’ll likely come away with a strong sense of place.

Skip or rethink if you want something easy. With the stated exclusions for back problems, mobility limitations, and low fitness, you’ll be happier choosing a gentler activity. And if you’re sensitive to sun or long walks, plan accordingly with sunglasses, a cap, and proper shoes—because those details can make or break your comfort.
