Clermont-Ferrand to Exeter Road Trip: Essential Guide

This 1,200-kilometer route from Clermont-Ferrand to Exeter begins at the foot of the Chaîne des Puys volcanic range, a UNESCO World Heritage site. The drive crosses the Massif Central, the Loire Valley, the Paris Basin, and the Channel, ending in the rolling hills of Devon. The route involves the A71, A10, A28, and A16 in France, then the M20, M25, and M5 in the UK. Total driving time is about 12 hours without stops.

One specific quirk: the A71 near Clermont-Ferrand has a unique 3.2 km downhill section with a 6% gradient, requiring engine braking. For the Channel crossing, the Eurotunnel (35 min) or ferry (90 min) are options. An alternate route uses the A75 and A85, adding 30 minutes but avoiding Paris traffic.

Fuel costs depend on your vehicle: an average car (7L/100km) will use 84 liters. At €1.80/L in France and £1.50/L in UK, total fuel cost is about €151 + €75 = €226. Diesel cars save about 20%. Toll roads in France (A71, A10, A28) cost about €60 total. The UK has no tolls except the M6 Toll (avoidable).

Fuel station distribution: In France, stations every 20-30 km on autoroutes, but closed 12am-6am in rural areas. In UK, every 30-40 km on motorways, often 24h. Topography: the Massif Central ascent/descent affects fuel economy; use cruise control at 110 km/h to save up to 15%.

• Recommended fuel apps: GasoilNow (France), PetrolPrices (UK)
• Toll payment: Credit card or electronic tag (Liber-t)
• Ferry booking: LeShuttle or Brittany Ferries

The drive begins among the extinct volcanoes of the Chaîne des Puys, then descends into the Limagne plain. North of Clermont, the landscape flattens into the Beauce wheat fields, then the rolling hills of Normandy. After the Channel, the English countryside opens with the North Downs, then the Somerset Levels, and finally the Devon moors.

Geographical shifts: Volcanic peaks (1,465 m) to sea level at Calais, then coastal cliffs to Exeter. Best viewpoint: the Puy de Dôme (accessible by cog train) offers a panorama of the entire route start.

• Chaîne des Puys: 80 volcanoes, UNESCO since 2018
• Loire Valley: châteaux along the river, detour to Chambord (15 min off A10)
• Normandy: Mont Saint-Michel (40 min detour from A84)
• Exmoor National Park: dark sky reserve, near Exeter

UNESCO sites along route: Chartres Cathedral (near A11/ A10), Mont Saint-Michel (detour), Palace of Westminster/Canterbury (in UK section). Locally, the Puy de Dôme is a UNESCO Global Geopark.

Local commerce: In Auvergne, buy Saint-Nectaire cheese and Le Puy lentils. In Loire, try fouace (sweet bread) and rillettes. In Normandy, cider and Calvados. In Devon, clotted cream and fudge. Markets: Saturday market at Issoire (10 min off A75), Wednesday market at Honfleur (near A29).

• Cheese stop: Fromagerie du Mont-Dore, near Clermont
• Cider farm: Ferme de la Bataille, Pays d'Auge

Road quality: French autoroutes are excellent, with smooth asphalt and good lighting. UK motorways are also good but have more narrow lanes. Safety tips: watch for speed cameras in France (fixed and mobile), and in the UK, average speed zones are common. Toll booths: have cash or card ready.

Night illumination: French autoroutes are lit near junctions, but dark sections exist. UK motorways are well-lit. Winter conditions: Massif Central can have snow from November to March; carry chains.

• Speed limits: France 130 km/h (110 in rain), UK 70 mph (112 km/h)
• Emergency: Dial 112 in both countries
• Breakdown: French autoroutes have orange emergency phones every 2 km

Family stops: Le Pal (amusement park near Dompierre-sur-Besbre, 1h off A71) or ZooParc de Beauval (1.5h off A10). In UK, Diggerland (Kent) or Crealy Adventure Park (near Exeter). Interactive museums: Cité de l'Espace in Toulouse (too far), but for kids: the Vulcania theme park near Clermont (volcano science).

Pet-friendly stops: Many French autoroute rest areas have designated dog walks (espaces canins). In UK, services like Tebay have pet-friendly sections. Cafes: Starbucks at Chartres (A11) allows dogs, and the M&S Simply Food at Exeter services has a pet area.

Hidden off-route gems: The abandoned village of Celles-sur-Ource (near A5, not on route) – a 15-min detour to see deserted stone houses. Or the medieval ghost town of Oradour-sur-Glane (near Limoges, 2h detour). For a quick stop: the tiny church of Saint-Jean-Baptiste in Bagneux (near A16) has a 12th-century fresco.

Fatigue management: Key rest zones – Aire de Bourges (A71, 2h from start) with shaded parking; services at Aire d'Allonnes (A10, near Le Mans); and the Exeter Gateway services on M5. For a nap, use the free “Nap Parking” at French rest areas (up to 3 hours). The safest are those with 24h surveillance.
