Also, the abandoned WWI fort at Fort de la Pompelle (A4, 5 min south of Reims) is a fascinating stop. Culinary gems: try a flammkuchen at Wirtshaus am Rosengarten in Baden-Baden, and a real Welsh rarebit at The Cottage Loaf in Llandudno.

The optimal route is Baden-Baden (A5) – Karlsruhe (A8) – Saarbrücken (A6) – Reims (A4) – Calais (A16) – Dover (ferry) – M20/A2 – M25 – M40 – A5 – M6 – A55 – Llandudno.

Geographical shifts: the Black Forest (dense conifers and rolling hills) gives way to the Rhine Valley (flat vineyards), then the Champagne region (sculpted chalk hills), and finally the Welsh mountains (Snowdonia, dramatic peaks). Each area offers unique local commerce.

• UNESCO World Heritage Sites: Reims Cathedral (Notre-Dame de Reims, along route), Chauvet Cave (near Vallon-Pont-d'Arc—too far for a short detour), and Pontcysyllte Aqueduct (near Wrexham, 30 min detour from A55).
