Due to the rural nature of much of Ayrshire it is unlikely you will encounter any crime if you stick to regular tourist activities. Nevertheless, if in the centre of one of the larger towns such as Kilmarnock, there is the potential to encounter drunken or otherwise undesirable individuals, particularly on a Friday or Saturday night. With this said, it is exceptionally rare that a tourist visiting the area will be the victim of crime.

As with the rest of the UK, English is spoken, but proficiency in foreign languages is very rare. At best you may encounter someone with a grasp of French, but this is to be regarded as an exception.
