Harbour Island in the Bahamas is home to one of the world's most jaw-dropping stretches of shoreline — three miles of rose-tinted sand that looks like someone spilled a giant bottle of rosé. The pink hue comes from crushed coral, shells, and the microscopic remains of foraminifera, a tiny red-shelled organism. Locals act completely unbothered by the fact that they live next to something that looks like a fantasy.
