Killarney to Ostend: Epic Road Trip Guide

The journey from Killarney, Ireland, to Ostend, Belgium, spans approximately 1,100 km (683 miles) and crosses three countries: Ireland, the United Kingdom (via ferry), and Belgium. Historically, this route follows ancient trading paths and modern motorways, with a unique quirk: the M20 motorway in Ireland ends abruptly at a roundabout near Rathmore, requiring a careful merge onto the N22. This drive offers diverse landscapes from Irish lakes to Belgian coastlines.
