Capri

Just 10.4 sq km off the Sorrentine Peninsula in Italy's Bay of Naples, Capri has captivated emperors, artists, and travellers for two millennia. The Blue Grotto (Grotta Azzurra) sea cave illuminated by refracted sunlight, the faraglioni rock stacks rising 109m from the sea, and Villa Jovis — the clifftop palace where Emperor Tiberius ruled Rome from 26-37 AD — make this tiny island an unrivalled concentration of natural wonder and ancient history.
