Nantes to Collioure Road Trip: Ultimate Guide to France's Scenic Southwest

Stretching 700 kilometers from the Loire estuary to the Vermilion Coast, the Nantes-Collioure route spans France's southwest diagonal. The fastest path uses the A11, A10, A62, and A9 autoroutes, taking about 7 hours without stops.

The A63 variant offers a coastal detour via Bayonne and Biarritz, adding 90 minutes but rewarding with Atlantic views. Near Calais? The A106 links to the A6 via Périphérique, but that's for a different trip.

This guide treats the A62/A9 axis as primary, with options for the Bordeaux wine route or the D933 through Lot-et-Garonne backroads. Each route offers distinct rhythm and discovery.

From the flat Loire vineyards (Muscadet) to Bordeaux's Châteaux (Pomerol, Margaux). The Dordogne valley near Bergerac offers walnut groves and prehistoric caves.

South of Montauban, the A62 climbs through the Garonne valley with sunflower fields and medieval bastides. The A9 dives into Roussillon's red cliffs and the Pyrenees foothills.
