With large expanses of sweeping sand dunes, Lençóis Maranhenses might appear to be your average desert. But for six months of the year, crystal blue lagoons turn the arid region into a cool summer hot spot.

Located in the Brazilian state of Maranhao, the national park is inundated with rainstorms from January to June of every year. The rainwater that collects between the sand dunes paints a stunning landscape covered in thousands of crystal clear lagoons.
