Barreirinhas Essentials

Barreirinhas serves as the primary entrance to the Lençóis Maranhenses National Park, a 155,000-hectare protected area characterized by rolling white sand dunes and seasonal rainwater pools. This collection features the high-altitude viewpoints of Lagoa Bonita and the deep waters of Lagoa Azul. It also includes the 35-meter Preguiças Lighthouse in Mandacaru and the remote oasis of Baixa Grande. Local gastronomy is represented by traditional seafood establishments specializing in the region's grilled shrimp and river-side dining along the Preguiças River.
