Introduction: The Atlantic Arc Crossing
The Oviedo to Cardiff road trip spans approximately 1,900 km (1,180 miles), crossing Spain, France, and the UK along the Atlantic Arc. This route takes drivers through the Bay of Biscay's rugged coast, the Loire Valley's châteaux, and the green hills of South Wales. A unique fact: the shortest sea crossing is from Roscoff to Plymouth (6 hours), but some prefer the longer Santander-to-Portsmouth ferry for a direct link.
