Choosing between the Lagoa Azul and Lagoa Bonita circuits is the single most common dilemma travelers face in Barreirinhas, the main gateway to Lençóis Maranhenses National Park. While both circuits showcase the park’s surreal landscape of wind-sculpted white quartz dunes and crystal-clear rainwater lagoons, they offer contrasting physical demands, costs, and ideal visit times.
In short: Circuito Lagoa Azul is flatter, slightly cheaper (R$ 80 to R$ 130 per person), and perfect for a relaxed morning swim across gentle rolling dunes. Circuito Lagoa Bonita sits atop a 30-meter high dune accessible via a 140-to-160-step wooden staircase, costing between R$ 120 and R$ 180 per person, and delivers Brazil’s most celebrated panoramic sunset.
Lagoa Azul vs Lagoa Bonita: The Quick Comparison Matrix
To help you decide which tour suits your schedule, budget, and fitness level, here is how the two flagship Barreirinhas circuits compare side by side:
| Feature | Circuito Lagoa Azul | Circuito Lagoa Bonita |
|---|---|---|
| Shared Tour Price (2026) | R$ 80 – R$ 130 per person | R$ 120 – R$ 180 per person |
| Physical Effort | Easy to moderate (gentle sand slopes, no stairs) | Moderate to strenuous (140–160 step wooden staircase up 30m dune) |
| Optimal Time of Day | Morning (08:30 – 13:00) | Afternoon / Sunset (14:00 – 18:30) |
| Highlight Experience | Calm crystal-clear swimming (Preguiça, Peixe, Esmeralda) | 360-degree panoramic sunset view over endless dune field |
| 4×4 Trail Transit Time | 40–50 minutes each way | 50–60 minutes each way |
| Key Lagoons Included | Lagoa Azul, Lagoa da Preguiça, Lagoa da Esmeralda, Lagoa do Peixe | Lagoa Bonita, Lagoa do Maçarico, Lagoa do Clone |
If you have multiple days in Barreirinhas, the best strategy is to do both on separate days. If you only have one full day, you can combine them into an unforgettable morning-and-afternoon double excursion.
Circuito Lagoa Azul: Relaxed Swimming and Gentle Rolling Dunes
The Lagoa Azul circuit is the classic, family-friendly introduction to Lençóis Maranhenses. Located geographically closer to Barreirinhas, the 4×4 trails leading here are slightly shorter, and the vehicle drops passengers at a parking perimeter right beside the first dune ridge.
Unlike Lagoa Bonita, there is no towering dune barrier to scale at the start. Visitors simply step off the open-sided 4×4 truck, take off their footwear, and walk across gentle, undulating slopes of soft white quartz sand. Within 5 to 10 minutes of easy walking, you reach the first lagoons.
The circuit typically visits several distinct freshwater pools:
- Lagoa Azul: The circuit namesake, famed for its deep cyan-blue hue on sunny mornings.
- Lagoa da Preguiça: A shallow, tranquil pool with warm water, often the first stop for a relaxed dip.
- Lagoa da Esmeralda: A striking pool whose green tint contrasts vividly with the brilliant white sand.
- Lagoa do Peixe: One of the rare perennial lagoons in the park that retains water through much of the dry season, home to small native fish (traíras) that survive in underground aquifers.
Because the terrain involves relatively flat walking, Circuito Lagoa Azul is the superior choice for seniors, families with small children, or travelers recovering from a long transit day. Morning departures (around 08:30) are recommended because the morning sunlight strikes the water directly overhead, producing stunning turquoise colors before the midday heat peaks.
Circuito Lagoa Bonita: The 150-Step Staircase and the Ultimate Sunset
If Lagoa Azul is about swimming comfort, Circuito Lagoa Bonita is about raw visual drama. Located further south in the National Park, this circuit is famous for its towering 30-meter dune ridge that overlooks the entire sea of sand.
When your 4×4 arrives at the base of the dune, you are greeted by the circuit’s defining architectural feature: a steep wooden staircase of approximately 140 to 160 steps. In years past, visitors had to pull themselves up the loose sand slope using a thick rope. The wooden stairs make the climb significantly safer, but climbing 150 steps in tropical heat still requires a moderate level of cardiovascular effort. Take your time, stay hydrated, and use the handrails.
The reward upon reaching the top is breathtaking: an unbroken 360-degree panorama of rolling white dunes stretching as far as the eye can see, punctuated by vibrant blue and green rainwater lagoons.
Key highlights of the Lagoa Bonita circuit include:
- The Panoramic Dune Ridge: The elevated vantage point provides the most photogenic perspective in all of Lençóis Maranhenses.
- Lagoa Bonita: A large, deep freshwater lagoon directly behind the main ridge, offering fantastic deep swimming.
- Lagoa do Clone: A picturesque lagoon named after the famous Brazilian telenovela O Clone, which filmed key scenes on these exact dunes.
- Lagoa do Maçarico: A peaceful secondary stop often used by guides when main pools become lively.
Afternoon departures (between 13:30 and 14:00) are standard for Lagoa Bonita. You spend the warm afternoon swimming in the lagoons, and by 17:15, everyone gathers back at the top of the main dune to watch the sun dip beneath the sandy horizon in a spectacle of purple, orange, and gold.
The 4×4 Jardineira Journey: Ferry Crossings and Bumpy Sand Trails
Reaching either lagoon circuit is an off-road expedition in itself. The journey from your hotel in Barreirinhas involves two distinct phases that every traveler should anticipate:
- The Rio Preguiças Balsa Crossing: Vehicles must cross the Preguiças River on a small motorized wooden ferry (balsa). The crossing takes only 5 to 10 minutes, but during peak July holiday mornings, there may be a short queue of 4×4 trucks waiting at the ramp.
- The Sand Trail Trek: Once across the river, the paved road ends immediately. You travel in a jardineira—a specially modified 4×4 Toyota pickup truck fitted with open-air passenger benches and a canvas canopy. The 40 to 60-minute drive winds through deep sand ruts, low restinga scrub, and muddy seasonal puddles.
The ride is noticeably bumpy and dusty. If you have back issues, try to sit toward the front of the vehicle cabin rather than the rear tailgate where bumps are magnified. Hold onto the metal bars, wear sunglasses with a strap, and keep your phone or camera tucked inside a sealed pouch to protect delicate lens mechanisms from fine blowing sand.
How to Schedule Both: The 1-Day Sprint vs. The 2-Day Relaxed Plan
How should you organize your visit to maximize time and avoid exhaustion? Here are the two proven itinerary models:
Option 1: The 1-Day Double Circuit (High Energy)
If you only have one full day in Barreirinhas, you can complete both circuits back-to-back:
- 08:30 – 12:30: Circuito Lagoa Azul morning tour. Enjoy the calm water and gentle walking while temperatures are moderate.
- 12:30 – 14:00: Return to Barreirinhas for a leisurely lunch along the Rio Preguiças waterfront and rehydrate in air conditioning.
- 14:00 – 18:30: Circuito Lagoa Bonita afternoon tour. Climb the wooden stairs, swim in the deeper lagoons, and watch the sunset from the dune crest.
Note: Doing both in one day means spending roughly 2.5 hours total bouncing on 4×4 benches. It is exciting and completely feasible for active travelers, but can be tiring for young kids or anyone sensitive to motion.
Option 2: The 2-Day Split (Recommended)
If your travel schedule permits two days in Barreirinhas, split the tours across consecutive days:
- Day 1 Afternoon: Arrive in Barreirinhas, settle into your pousada, and take the 14:00 Circuito Lagoa Bonita sunset tour.
- Day 2 Morning: Take the 08:30 Circuito Lagoa Azul tour for a refreshing morning swim, leaving the afternoon free for a boat excursion down the Rio Preguiças toward Atins or Caburé.

Essential Survival Rules: What to Pack and Park Etiquette
Because Lençóis Maranhenses is a strictly protected federal National Park managed by ICMBio, there are no beach bars, restaurants, or permanent restrooms once you enter the dunes. Keep these practical rules in mind:
- Leave Your Footwear in the 4×4: Do not attempt to hike the dunes in sneakers, heavy hiking boots, or flip-flops. Footwear fills with dense sand immediately. The local standard is to leave shoes in the truck and walk completely barefoot across the soft, cool quartz sand.
- Pack Minimum 1.5 Liters of Water Per Person: The combination of reflective white sand, dry wind, and tropical sun dehydrates you quickly. Bring sufficient water and light snacks in your daypack.
- Seal Electronics in Dry Bags: Constant Atlantic trade winds blow fine quartz grains across the dunes. Carry a ziploc bag or waterproof dry bag for your smartphone and camera gear.
- Strict Conservation Rules: Private uncertified vehicles, motorized watercraft, and alcoholic beverages are strictly prohibited inside the park. All trash, including fruit peels and wrappers, must be packed out and disposed of back in town.
