Lençóis Maranhenses National Park, located in the state of Maranhão, was established in 1981 with the goal of preserving one of the most impressive and unique ecosystems in the world. Covering an area of 155,000 hectares, the park is known for its vast white sand dunes and crystal-clear lagoons that form between them during the rainy season. The creation of the park was motivated by the need to protect this unique natural landscape, which is the result of a singular geological process of sediment accumulation brought by the Preguiças River and the action of the winds. In addition to the dunes and lagoons, the park is home to a rich biodiversity, including bird, fish, and reptile species adapted to the region’s extreme conditions. Today, Lençóis Maranhenses National Park is managed by the Chico Mendes Institute for Biodiversity Conservation (ICMBio) and is a renowned international tourist destination, attracting visitors eager to explore its surreal landscapes and connect with untouched nature.
Lençóis Maranhenses National Park is essential for the preservation of a unique ecosystem on the planet, where the desert-like dunes dynamically interact with the fresh waters of the seasonal lagoons. In addition to protecting this exceptional landscape, the park plays a crucial role in conserving the region’s fauna and flora, including species adapted to the extreme conditions of the dunes and wetlands. For Brazil, the park is a symbol of natural beauty and ecological diversity, contributing significantly to ecotourism and the economy of local communities. Tourism activities in the park also raise environmental awareness, encouraging the preservation of this natural heritage.
Access to Lençóis Maranhenses National Park is free. However, to explore some of the more remote areas or take guided activities, such as boat trips along the Preguiças River or 4x4 tours through the dunes and lagoons, fees vary depending on the tour operator. Hiring local guides is highly recommended to ensure a safe and enriching experience. The park is easily accessible from the towns of Barreirinhas, Santo Amaro, and Atins, where a wide range of tourist services can be found. Some activities, such as the park crossing on foot, require more planning, and it is important to book in advance.
To make the most of your visit to Lençóis Maranhenses National Park, wear light clothing and comfortable shoes, ideal for walking on sand and exploring the lagoons. Don’t forget sunscreen, a hat or cap, and insect repellent, as sun exposure is intense. Stay hydrated by bringing plenty of water, and take light snacks such as fruit and cereal bars for the hikes and tours. Always follow the signs and the instructions of the park’s guides and staff. Stay on designated trails to minimise environmental impact. Avoid feeding the animals and keep a safe distance from local wildlife. Take all your rubbish with you and use the bins provided. Respecting conservation rules is essential to ensure that future generations can enjoy the same natural wonders.
The best time to visit Lençóis Maranhenses National Park is between May and September when the lagoons are full after the rainy season, offering the most spectacular landscapes. During the dry season, from October to March, the lagoons begin to dry up, but the dune landscape still offers a unique experience. Rain occurs between January and April, making access to the park more difficult but ensuring that the lagoons are replenished for the next season. Each time of year offers a different view of Lençóis, and the choice of when to visit depends on visitors' preferences.
For visitors coming from Europe, the best entry point is Marechal Cunha Machado International Airport (SLZ) in São Luís, the capital of Maranhão.
