If I am driving to Killarney from Dublin which is the quickest route. Is it via Limerick or Cork or some other route? Forget about the scenic element of the trip.
Via Limerick, stick to main route, motorway most of the way and from Limerick on road quite good through Newcastlewest/Abbeyfeale etc. Worst bit is through Adare if you hit it the wrong time as in anything from about 4 p.m. onwards.
