Most visitors accessing Lençóis Maranhenses from Barreirinhas book either the Lagoa Azul or Lagoa Bonita circuit. Both require authorized 4x4 transport and take about four to five hours. Deciding which one is better depends on your fitness level and whether you prefer morning colors or evening views.
What is the Lagoa Azul circuit?
It is a 4-to-5-hour guided trip to a series of easily accessible, bright blue seasonal pools.
This classic route is known for its blue water and straightforward access. The walking paths over the dunes are relatively gentle. You will spend time swimming in the freshwater pools and walking between the main lagoons.

What is the Lagoa Bonita circuit?
It is a half-day tour featuring a steep 30-meter (98-foot) dune climb to reach a panoramic viewpoint.
The Bonita circuit requires more physical effort right at the start. Visitors use a rope to climb a massive sand dune. The reward is a 360-degree view over the entire dune field.

Which tour is better for morning or afternoon?
Lagoa Azul is best at 8:00 AM, while Lagoa Bonita is better in the afternoon for sunset.
Morning sunlight sits directly overhead at Lagoa Azul. This angle brings out the brightest turquoise colors in the water. Lagoa Bonita is widely considered the best sunset viewpoint in the park, making the afternoon departure ideal.
How do the two circuits compare?
Both take half a day and cost 160 to 220 BRL on a shared tour, but they differ in effort and timing.
Here is a quick breakdown of the main differences between the two primary circuits.

Can you do both circuits in one day?
Yes, you can book a full-day combo tour that visits both lagoon areas.
Because each circuit takes four to five hours, you can do Azul in the morning and Bonita in the afternoon. A combined 10-to-12-hour excursion lets you see both, though it makes for a long, hot day in the sun.
How much do these tours cost?
A standard shared half-day 4x4 tour costs between 160 and 220 BRL per person.
Prices change based on the operator and season. The national park itself charges 0 BRL for entry. You are only paying for the licensed 4x4 vehicle and the mandatory guide. Private tours cost significantly more.

Questions travellers ask
Can I drive my own car to Lagoa Azul or Bonita?
No. Private vehicles and rental cars are strictly prohibited inside the dune zones. You must use an authorized 4x4 guide.
Are the lagoons always filled with water?
No. The lagoons are seasonal. They fill heavily between January and May and peak from June to September.
Is it safe to swim in the lagoons?
Yes. The pools are crystal-clear freshwater. Remember to apply biodegradable sunscreen to protect the fragile ecosystem.
