Also, there are so many options for you to start your journey in a variety of places all around the Republic of Ireland (most popular airports: Cork Airport, Donegal Airport, Kerry Airport, Knock Airport, Shannon Airport; and other towns and cities: Limerick, Galway, Waterford, Drogheda, Dundalk etc.) and in Northern Ireland (Belfast Airport and other locations in Belfast, Derry, Craigavon etc.)
