Up close, these villages, particularly Oia at the island’s northmost tip, can be absurdly picturesque, all winding stone alleyways and narrow steps, with pathways running over rooftops, tiny, domed shops selling every kind of tourist tat and questionable Greek fashion, and vivid bougainvillea, all beneath a flawless blue sheet of sky. Every so often, as I wandered around, I had to leap into the nearest doorway to avoid being mown down by a caravan of donkeys, all done up in bright tassels and blankets, being led down the hill at a brisk trot in order to haul red-faced tourists back up from the seafront far below.
