Dun Laoghaire, Dalkey, and Killiney Loop Walk is a 8.5 mile loop trail located near the city of Dun Laoghaire that offers scenic views and is rated as moderate. The trail is primarily used for hiking and walking and is accessible year-round.
Follow the coast around the smart suburbs of south-east Dublin and return via a historic walkway. Situated between the mountains and the sea, the coastal area on the south side of Dublin Bay from Dun Laoghaire to Killiney encompasses a number of attractive seaside towns and harbours as well as places of historical and literary significance and sites of ecological importance. The history of the development of this area is tightly bound to the history of Dublin City, especially the difficulties involved in navigating ships into Dublin Port. The great harbour in Dun Laoghaire was built as an asylum for ships to protect them from the storms that batter the Irish Sea. Before its construction, the small harbours around Dalkey developed as a safer alternative place to land with passengers and crew. The great granite quarries of Dalkey also supplied most of the stone used to build Dun Laoghaire Harbour and The Metals, the route the wagons carrying the stone used to travel from quarry to building site, still survives to this day. This walk takes you from the seaside town of Dun Laoghaire and its harbour along the coast through Sandycove and Dalkey before climbing to the summit of Killiney Hill, overlooking the great sweep of Killiney Bay, a view compared with that of the Bay of Naples, and then returning to Dun Laoghaire along the historic route of The Metals.
