The vibrant pinks and contours of the first landscape shot caught our eyes, which made us wonder where the extraordinary place photographed is. Turns out it’s Lençóis Maranhenses National Park in the northeastern state of Brazil, Maranhão, and a lucky few who have visited this unique location took these remarkable photos of it. Nearby the Amazon rainforest, the park receives substantial seasonal rain that creates lagoons surrounded by white-sand hills and a natural habitat for freshwater fish and seabirds to flourish.
