The bustling harbor town of Dún Laoghaire (pronounced Dun Lear-y) is one of a string of Dublin commuter towns that, in the 2000s, became known as “Bel Eire” for their beauty and for the density of Irish celebrity residents. You could spend an afternoon wandering here; there are plenty of interesting shops, a bucolic park, and the long promenade alongside the harbor is a beautiful spot.
