Brest to Westport Road Trip: Atlantic Coast Gems

The route from Brest (France) to Westport (Ireland) is a trans-European adventure across the Celtic Sea, combining two of the Atlantic's most dramatic coastlines. The shortest ferry crossing is from Roscoff, 60 km north of Brest, to Cork, then a 4-hour drive to Westport. Total driving time on land is about 9 hours, excluding ferry. A quirky local fact: the N59 in County Mayo follows an ancient drover's route, and on clear days you can see Croagh Patrick from 30 km away.
