Brussels to Killarney Road Trip Guide: Epic Drive

The journey from Brussels to Killarney spans approximately 1220 km, crossing Belgium, France, England, Wales, and Ireland. A unique quirk: the Irish side of the road demands driving on the left, a shift from continental right-hand driving. The route largely follows the E40 to Calais, then the A16/M20/A2 through the UK, and finally the M7/M20 in Ireland. Expect a total driving time of around 15-16 hours excluding stops, but with breaks and sightseeing, plan for 2-3 days.
