Bristol to Quimper Road Trip: Complete Guide

The route from Bristol to Quimper is a 480-mile (770 km) journey that combines motorway efficiency with the scenic beauty of Devon, Cornwall, and Brittany. A unique quirk: you drive on the left in the UK and on the right in France, requiring a ferry crossing that resets your orientation.

The total driving time, including the ferry (Plymouth to Roscoff or Portsmouth to St Malo), is around 10–12 hours. The route uses the M5, A30, and A38 in the UK, and the N12 and D785 in France.

Fuel costs vary: UK petrol ~£1.50/L, French diesel ~€1.70/L. The route features ample service stations: M5 services (Taunton, Exeter), A30 (Launceston), and French N12 (Morlaix).

• M5 junction 21 (Weston-super-Mare) to A30 via M5 junction 31 (Exeter)
• A30 to A38 near Bodmin for Plymouth
• French N12 from Roscoff to Morlaix, then D785 to Quimper
• Consider Portsmouth–St Malo ferry for a longer but scenic alternative

Road quality is excellent on motorways, but single-carriageway A-roads in Devon and Cornwall require caution. French roads are well-maintained, with roundabouts prevalent.

• UK: M5 has average speed cameras; A30 has mobile enforcement
• France: N12 is dual carriageway with 110 km/h limit
• Rest zones: Exeter services (M5), Launceston (A30), Morlaix aire

For families: stop at Crealy Adventure Park (Exeter) or Océanopolis (Brest, detour). Pet-friendly: many UK service stations allow dogs; French aires have dog relief areas. Fatigue warning: plan a break every 2 hours.

The drive traverses Dartmoor National Park (A30), with its rugged tors and ponies. In Brittany, the N12 passes near the Monts d'Arrée, a wild moorland reminiscent of Scotland.

• Dartmoor: hike to Haytor Rocks (10 min off A30)
• Cornwall: stop at Eden Project (near St Austell, 20 min detour)
• Brittany: visit the medieval town of Morlaix (viaduct and old town)

Local commerce includes farm shops in Devon (e.g., Okehampton Farmers Market) and Breton crêperies in every village. For hidden gems, check out how to find the best stops and hidden gems between cities.
