Lençóis Maranhenses National Park is a vast expanse of white sand dunes and seasonal rainwater lagoons. Visiting requires choosing a base, hiring an accredited vehicle, and traveling during the season when the lagoons are full.
Barreirinhas, Santo Amaro, and Atins offer different experiences—don’t treat the park as a single, one-size-fits-all excursion.
What are the Lençóis Maranhenses like?
The park is made up of dune fields broken up by rainwater lagoons. The landscape changes throughout the year and between circuits; what you see depends on the rain, the wind, and the access allowed on the day.
Which base should you choose?
Barreirinhas has the most lodging and tour options; Santo Amaro is close to circuits with more direct access; Atins combines lagoons, kitesurfing, and a village vibe. To compare planning, also check out how to choose your base in Lençóis.
