A Coruña to Blois Road Trip: Ultimate Guide

The road from A Coruña (43.3623° N, 8.4115° W) to Blois (47.5861° N, 1.3359° E) covers roughly 950 km (590 mi) across Spain and France, crossing the Bay of Biscay via ferry. A historical fact: this route roughly follows the old Way of St. James (French route) in reverse, with Blois marking the gateway to the Loire Valley castles. The drive takes about 10-11 hours excluding the ferry crossing from Santander to Portsmouth (or a long detour via the A63/E5 through France). For a direct overland route, you'd face a 14-hour drive via Bordeaux and Paris, but the standard itinerary involves a ferry to save time. Our guide focuses on the ferry-plus-drive plan, with key stops in northern Spain and central France.
