Barreirinhas

Barreirinhas is located at the northern edge of Maranhão state and features white sand dunes, seasonal lagoons, and a network of rivers that serve as transportation routes. The landscape combines water and desert features that cut through the terrain.

Portuguese settlers established this municipality in the 18th century as an agricultural center focused on sugar cane and rice cultivation along the Preguiças River. This early economic focus shaped the settlement pattern and use of river resources.

The town hosts local celebrations throughout the year that blend indigenous traditions with Portuguese colonial influences and regional music performances.

Visitors can reach this municipality by regular bus services from São Luís, with the journey taking approximately four hours on paved roads. The best time to visit is during the dry season when the lagoons become more visible and accessible.

The territory contains part of Lençóis Maranhenses National Park, where rainwater creates thousands of clear blue lagoons nestled between massive sand dunes. This seasonal water formation results from the interaction of heavy rainfall and the region's unique sand geology.
