With recently completed highways to Waterford and Kilkenny, a car is the best option for covering ground quickly and easily. Waterford City, the regional capital, is easily accessible from all parts of Ireland.
From Dublin, take M7 southwest, change to the M9, and continue along as it bypasses Carlow Town and Thomastown until it ends in Waterford. N25 travels east–west through Waterford City, connecting it with Cork in the west and Wexford Town in the east. From Limerick and Tipperary Town, N24 stretches southeast until it, too, ends in Waterford City.
For the most part, the main roads in the Southeast are of good quality and are free of congestion. Side roads are generally narrow and twisting, and you should keep an eye out for farm machinery and animals on country roads.
