7Sarakiniko Beach, Milos (Greece)

Sarakiniko is the closest thing you’ll find to the moon without leaving Earth. Waves and wind have carved Milos’ volcanic rock into smooth, sculptural white formations that look like a lunar playground.

The contrast between blinding white cliffs and electric-blue water is so dramatic that many visitors assume Instagram exaggerates it — until they see it up close. Walking across this natural white “stone desert” with the Aegean beside you is a sci-fi dream come to life.
