Historically, Dún Laoghaire was a fort from which the fifth-century High King of Ireland, Laoghaire Mac Néill, conducted his European raids. A waterbaby’s dream, today the coastal town has a more peaceful vibe, and a visit provides an insight into Dublin’s history as a port as well as a chance to take a dip in the sea.
From early April to mid-October visitors to Dún Laoghaire have the chance to explore two of Ireland’s best diving sites: Dalkey Island and the Muglins rocks. In good conditions, both sites offer the potential to see a wealth of Irish marine life at depths of 8m-25m (25ft-80ft), from sponges and starfish to crab, lobster and dogfish. Oceandivers diving school is run by two of Ireland’s first Professional Association of Diving Instructors (Padi) with more than 20 years’ experience teaching, so even novices are in good hands here.
