Why go
Santo Amaro sits less than 2 km from Lençóis Maranhenses, where white dunes and freshwater lagoons meet local communities. You can enter on foot or in a licensed vehicle, since private cars aren't allowed, and authorized guides lead the named routes. Lagoon levels rise and fall with the rain, so each outing depends on conditions.
