Brazil
Lençóis Maranhenses
Vast white sand dunes stretch across coastal plains, forming temporary lagoons during rainy seasons.
Wind-sculpted sand dunes roll across 600 square miles of coastal plain, their surfaces shifting constantly under trade winds from the Atlantic. During the rainy season, rainwater collects in the valleys between dunes, creating thousands of turquoise and emerald lagoons that mirror the sky. The landscape feels both oceanic and desert-like, a place where freshwater pools appear and vanish with the seasons.
What draws people here
- —pristine white sand dunes that migrate with seasonal winds
- —seasonal freshwater lagoons trapped between shifting sand formations
