Britain and Ireland make an appealing combination for a city-hopping holiday, bringing together medieval castles, winding old streets, dramatic waterfronts and lively neighbourhoods where local life unfolds around pubs, markets and cafés. Each city has its own character, from Edinburgh’s historic skyline to Dublin’s literary heritage and Glasgow’s creative energy. Add the maritime atmosphere of Belfast, the Georgian architecture of Bath and the colourful streets of Cork, and there is plenty of variety without having to travel enormous distances.
