Just north of the city, the fishing village of Howth offers sea air, seals in the harbour and one of Dublin’s best coastal walks. This half-day guided tour whisks you out along the bay, up onto the cliff path for sweeping views over Dublin Bay and Ireland’s Eye, and into the village for its famous fish and chips. It is a refreshing escape from the city bustle. Pack a windproof jacket, as the headland catches every gust.
