Santorini roads might be a little tricky at first as they are nothing like the roads of a big city! If it is your first time driving in Santorini, you should remember you will drive through some curved roads due to the crescent shape of the island.
Within the various small towns and villages, the roads are narrow, often cobbled. You should keep in mind that some of them only allow one way driving. In many areas, there are no sidewalks so you should also keep an eye for pedestrians, stray cats & dogs.
