15 Unreal Natural Wonders You Have to See to Believe

9. Lençóis Maranhenses, Brazil – The Desert with Lagoons

Imagine a vast desert of rolling white sand dunes, but instead of being dry and barren, it's filled with crystal-clear blue and green lagoons. That’s Lençóis Maranhenses National Park in Brazil, a phenomenon caused by seasonal rainwater collecting between the dunes. For a few months every year, this surreal landscape becomes a paradise of hidden pools in the middle of the desert, perfect for swimming. The contrast between the blinding white sand and the vibrant turquoise water makes this place look like something straight out of a dream.
