Clermont-Ferrand to Speyer: A Scenic Road Trip via A75 & A5

The drive from Clermont-Ferrand to Speyer covers roughly 730 km (454 miles) and weaves through the heart of France into Germany. Unlike a direct autoroute, this route offers a dramatic shift from the volcanic Chaîne des Puys to the flat Rhine Valley, with the A75 cutting south of Massif Central before joining the A36 and A5 toward the border. A lesser-known fact: the A75 features the Millau Viaduct, the world's tallest cable-stayed bridge, rising 343 m above the Tarn River – a true engineering marvel. Expect 7-8 hours of driving time, but plan for at least two days to savor the stops.

• Total distance: Approximately 730 km (454 mi)
• Time: 7-8 hours pure driving; 2 days recommended for sightseeing
• Key highways: A75, A36, A5, then A61 in Germany

The journey is well-served by modern highways, but requires careful planning for tolls, fuel, and rest. The A75 south of Clermont-Ferrand is toll-free except for the Millau Viaduct (around €8.90 in 2025). After that, the A36 and A5 are partially tolled, costing about €45 total for the French section. In Germany, highways are toll-free for cars, but fuel prices are higher than in France by roughly €0.15 per liter.

• Fuel stops: Frequent along A75 and A5; plan for petrol stations every 40 km. LPG limited in rural areas.
• Fuel cost estimate: For a diesel car consuming 6 L/100km, total fuel ~44 L; at €1.70/L, about €75.
• Tolls: Total ~€54 for the entire route (France only).
• Parking: Rest areas with dedicated parking for naps (marked 'Aire de repos') every 20 km.

Departing Clermont-Ferrand, the landscape rises through the volcanic Chaîne des Puys, a UNESCO World Heritage site since 2018. The A75 then descends into the gorges of the Tarn and into the limestone plateaus of the Causses. As you head east, the terrain flattens into the fertile plains of the Franche-Comté, with the Vosges mountains in the distance, before dropping into the Rhine Valley's vineyards.

• UNESCO sites: Chaîne des Puys (short detour), also the Historic Fortified City of Carcassonne (south detour) or Strasbourg's Grand Île (near Speyer).
• Local commerce: In Auvergne, buy Saint-Nectaire cheese; in Alsace, stop for flammekueche and locally made eau-de-vie.
• Hidden gems: The village of Saint-Cirq-Lapopie (15 min from A20) or the abandoned Château de Saint-Ulrich in Alsace (5 min from A35).

The A75 is well-maintained with good lighting at interchanges, but fog can suddenly roll in over the Causses, reducing visibility to 50 meters. The A36 near Belfort often has strong crosswinds, so slow down if driving a high-sided vehicle. Speed cameras are frequent in France, including mobile units in construction zones.

• Family-friendly stops: Le Pal Animal Park (near Dompierre-sur-Besbre, 30 min from A79), or the Vulcania theme park near Clermont-Ferrand. Interactive museums like the Cité de l'Automobile in Mulhouse.
• Pet-friendly stops: Most rest areas have grassy zones; designated dog areas near Aire de la Chicane (A36). Several autoroute restaurants allow dogs on terraces.
• Fatigue management: Ideal rest points: Aire de la Lozère (A75, 44.5342° N, 3.2345° E) with panoramic views and shaded parking for naps. Aire de la Franche-Comté (A36) offers quiet spots.
