Lençóis Maranhenses 2026: A Travel Guide to Brazil’s Stunning Sand Dunes

Lençóis Maranhenses is one of Brazil’s most unusual natural destinations. Located in Maranhão in northeastern Brazil, this national park features white sand dunes and clear freshwater lagoons. 

In 2026, UNESCO recognized Lençóis Maranhenses National Park as a World Heritage Site. This guide covers the best time to visit, how to get there, where to stay, and what to know before booking your trip. 

Lençóis Maranhenses: Nature at Its Purest

The park covers more than 156,000 hectares of dunes, lagoons, beaches, and coastal ecosystems. Wind shapes the dunes, while rainwater fills the pools between them. The colours change throughout the year.

Visitors can swim in permitted lagoons, walk across the dunes, and enjoy wide-open views. The park is protected, so visitors must follow local rules and use authorized tour operators.

Grandes Lençóis and Pequenos Lençóis

Grandes Lençóis refers to the main dune landscape inside the national park. It includes many of the well-known lagoons and routes accessed from Barreirinhas and Santo Amaro.

Pequenos Lençóis is a separate dune area near the coast, outside the main park landscape.

It offers a different experience, with smaller dunes and coastal scenery. Ask local guides about the route and conditions before choosing an excursion.

São Luís do Maranhão: A Historic Coastal Capital

São Luís is the capital of Maranhão and a common starting point for trips to the national park. Its historic centre features colourful colonial buildings, traditional tiles, and streets shaped by Portuguese influence.

Spend a day exploring the city before heading to the dunes if your schedule allows. You can enjoy regional food, local music, and historic architecture before continuing to Barreirinhas or Santo Amaro.

Bumba-Meu-Boi

Bumba-Meu-Boi is one of Maranhão’s best-known cultural traditions. It combines music, dance, colourful costumes, and storytelling around the tale of an ox.

The celebration is especially prominent during the June festival season. If your visit falls around this time, check local event calendars for performances in São Luís and nearby communities.
