A Landscape Unlike Any Other
Imagine endless waves of pristine white sand dunes, sculpted by the wind and cradled between thousands of crystal-clear freshwater lagoons. This isn’t a mirage; it’s Lençóis Maranhenses National Park, one of Brazil’s most breathtaking and surreal natural wonders. Located in the state of Maranhão, this protected area spans over 1,550 square kilometers (600 sq mi) and offers an otherworldly experience that feels like stepping onto another planet. But despite its desert-like appearance, it’s a unique ecosystem that defies simple categorization. This guide covers everything you need to know to plan your unforgettable adventure.
What Exactly is Lençóis Maranhenses?
The name “Lençóis Maranhenses” translates to the “bedsheets of Maranhão,” a fitting description for the vast, rolling white dunes. What makes this park so unique is its climate. It receives a significant amount of rainfall during the first half of the year, which collects in the valleys between the dunes. This creates thousands of temporary lagoons, with some reaching depths of over 3 meters (10 feet). The water is filtered by the sand, making it incredibly clear and perfect for swimming. This seasonal phenomenon creates a landscape that is constantly changing, a desert that is full of life and water.
When is the Best Time to Visit?
Timing is everything when it comes to visiting Lençóis Maranhenses. To experience the park at its most magnificent—with full, vibrant lagoons under a sunny sky—you need to plan your trip carefully.
- Peak Season (June to September): This is the absolute best time to go. The rainy season has just ended, meaning the lagoons are at their fullest and most spectacular. The weather is dry and sunny, perfect for exploring the dunes and swimming.
- Shoulder Season (May and October): In May, the lagoons are still filling up, and you might encounter some rain. In October, they begin to recede, but many larger lagoons will still be there. You’ll also encounter fewer crowds.
- Off-Season (November to April): This is the rainy season. While essential for the park’s life cycle, it’s not ideal for tourism. Many lagoons will be dry or just beginning to form, and constant rain can disrupt tours.
How to Get to Lençóis Maranhenses
Reaching this remote paradise requires a few steps, but it’s well worth the journey. The main entry point is the city of São Luís (SLZ), which has an international airport.
From São Luís, you need to travel to one of the three main base towns:
- Barreirinhas: This is the largest and most popular gateway to the park. It has the most developed infrastructure with plenty of hotels, restaurants, and tour agencies. It’s about a 4-hour bus or shared van ride from São Luís.
- Santo Amaro do Maranhão: A quieter, more rustic town that offers access to some of the most beautiful and less-crowded lagoons. The journey here is a bit more rugged, requiring a 4×4 vehicle.
- Atins: A remote and charming fishing village situated where the Rio Preguiças meets the Atlantic Ocean. It’s perfect for travelers looking for a laid-back, off-the-beaten-path vibe and is a popular spot for kitesurfing.
Top Things to Do and See
Exploring Lençóis Maranhenses is done exclusively on 4×4 tours or boats with certified local guides, as navigating the vast, unmarked dunes is impossible for the uninitiated. Your choice of tours will largely depend on your base town.
From Barreirinhas
- Lagoa Azul Circuit (Blue Lagoon): A classic half-day trip that takes you to a series of stunning lagoons, including Lagoa Azul, Lagoa do Peixe, and Lagoa da Preguiça. It’s a perfect introduction to the park’s beauty.
- Lagoa Bonita Circuit (Beautiful Lagoon): This tour involves a steep climb up a dune, but your effort is rewarded with one of the most incredible panoramic views of the entire park.
- Rio Preguiças Boat Tour: Explore the region’s ecosystem by water. This full-day trip takes you down the Preguiças River to see the small villages of Vassouras (home to playful monkeys), Mandacaru (with its lighthouse offering amazing views), and Caburé.
From Santo Amaro
Many consider the lagoons near Santo Amaro to be the most impressive. A must-do is a tour to Lagoa da Gaivota (Seagull Lagoon) and Lagoa da Andorinha (Swallow Lagoon), where you can watch a spectacular sunset over the dunes.
Essential Tips for Your Trip
- Hire a Certified Guide: It’s mandatory to enter the park with a licensed guide. They are essential for navigation and your safety.
- Pack Smart: Bring lightweight clothes, a swimsuit, a hat, sunglasses, and strong sunscreen. A reusable water bottle is a must to stay hydrated.
- Bring Cash: While Barreirinhas has ATMs, smaller towns like Atins and Santo Amaro have limited or no banking facilities. Cash is king.
- Protect Your Electronics: Fine sand and water can be a deadly combination for cameras and phones. Bring protective cases or dry bags.
- Leave No Trace: This is a delicate and protected ecosystem. Take all your trash with you and respect the natural environment.
Lençóis Maranhenses National Park is more than just a destination; it’s a profound experience.
