Killarney to Tournai Road Trip Guide: Ultimate Cross-Europe Route

The route from Killarney, County Kerry (51.94° N, 9.50° W) to Tournai, Hainaut (50.61° N, 3.39° E) spans 1,070 km (665 mi) and typically requires 12–14 hours of pure driving time. This journey crosses Ireland via the N22, M8, and M11 to Dublin Port, then ferry to Holyhead, Wales, followed by the A55, A5, M6, and M1 through England to the Channel Tunnel or ferry to Calais, then the A16 and A1 to Tournai. An often-overlooked fact: the section between Holyhead and Manchester roughly follows the ancient Roman road Watling Street (now the A5), once a key route connecting Roman Britain.

Fuel costs vary: petrol in Ireland is about €1.60/L, the UK €1.45/L, and France €1.70/L. A mid-size car will spend roughly €150–€180 on fuel one-way. Tolls exist on the M6 in the UK (no tolls in Ireland or France on the A16/A1). The Channel Tunnel (LeShuttle) costs €80–€120 one-way depending on booking time; ferries from Dover to Calais are €30–€60.

• Ireland: M8 toll near Cashel – €1.90
• UK: M6 toll bypass at Birmingham – £8.90
• France: A16 and A1 are toll-free except near Paris; not applicable here
