Torquay to Tournai: Ultimate Road Trip Guide

The A38 from Torquay to Exeter becomes the M5, merging into the M4/A4 corridor toward London. Past the Dartford Crossing, the M20 leads to the Channel Tunnel at Folkestone. After emerging near Calais, the A16/E40 points southeast to Tournai. This 480-mile route crosses three countries, blending Devon hills, Kent orchards, and Belgian plains. The journey takes roughly 8 hours driving time, excluding breaks and Channel crossing.

Fuel costs vary: UK petrol averages £1.50/litre, France €1.80/litre, Belgium €1.65/litre. For a typical car (40mpg), total fuel cost ~£110-£130. The topography is mostly flat after the Devon hills, so fuel efficiency improves. Fuel stations are abundant along motorways, but rural sections (e.g., Devon A38) have fewer options; fill up at Exeter or Taunton. Toll roads: the Dartford Crossing (free with account), and French A16 (toll ~€10).

• Driving time: 8 hours (without stops + crossing)
• Recommended departing: 8am Torquay to avoid rush hour near Bristol
• Channel crossing: Book Eurotunnel (35 min) or ferry (1h30); Eurotunnel faster but more expensive (~£70 vs £50)
• Route: A38 → M5 → M4 → M25 → M20 → Eurotunnel → A16 → A1 (Belgium) → E429/E403 to Tournai

UK motorways are well-lit near cities, but night driving in rural Devon has unlit stretches. French A16 is well-maintained; Belgian motorways have good illumination near towns. Speed limits: UK 70mph, France 130km/h (80mph), Belgium 120km/h (75mph).

• Rest zones: At M5 junction 24 (Somerset), the Sedgemoor services have picnic areas. At A16 near Calais, the Haute Ville rest area offers open fields for dog walks.
• Family stops: the Royal Gunpowder Mills (M25 exit 27), Kent Life heritage farm (M20 exit 6).
• Pet-friendly: Most UK services allow dogs in designated areas; the Channel crossing (Eurotunnel) requires pets in carriers.

UNESCO Sites: short detours: the city of Bath (UNESCO) is 15 min from M4 junction 18; the Neolithic flint mines of Spiennes (UNESCO near Mons) are 30 min from Tournai.

Climate: southeast winds often hit the A20 in Kent; anticipate crosswinds on exposed sections. Sunset views over the Somerset Levels from the M5 around 7pm in summer.

Leaving Torquay, the road climbs through Haldon Forest, offering views over the English Riviera. The M5 cuts through Somerset Levels, a flat wetland. Near Bristol, the Severn Estuary opens up. Across the Cotswolds fringe, gentle hills with dry-stone walls. In Kent, the Garden of England, orchards and hop fields dominate. Post-Channel, the flat Flanders plain stretches toward Tournai. This shift from rolling hills to pancake-flat topography is striking.

• Hidden off-route spots: 5 min from M20 exit 10, the village of Boughton Aluph has a medieval church and duck pond. In France, 5 min from A16 exit 25, the abandoned fort of Fort d'Ambleteuse overlooks the coast.
• Local commerce: Kentish apple juice at roadside stalls near Maidstone; Belgian waffles and chocolate at Tournai's Grand Place market (Saturdays).
