Motorways are well-lit and fenced, but sections of A16 near Abbeville have narrow hard shoulders. In rain, the steep slip roads at the Channel Tunnel terminal can be slippery. Always have a high-vis vest and warning triangle in France.

• Fatigue breaks: every 2 hours at Aire de la Baie de Somme (playground, picnic area) or Aire de la Côte d'Opale (24h café).
• Child suitability: Nausicaá aquarium in Boulogne (50,000 sq ft) for kids; Parc d'Olhain near Béthune has adventure trails.

Pet-friendly framework: dogs under 8 kg can travel free in Eurotunnel (carrier required). French motorway rest stops often have dog walking areas. Many Honfleur hotels, like La Maison de Lucie, accept pets.

The White Cliffs of Dover (UNESCO tentative) dominate the English coast. In France, the Opal Coast features dramatic cliffs at Cap Blanc-Nez and Cap Gris-Nez, with views across the Channel. Further south, the Seine estuary near Honfleur offers marshland and old fishing ports.

• Stop at Pointe du Hoc: D-Day cliffs with bunkers, free entry, 30 min detour from A13.
• Normandy's apple orchards: Visit a cidrerie along the D579, like Domaine Dupont for calvados tastings.

Local commerce thrives on produce: cheese (Camembert, Livarot), cider, and seafood. Boulogne-sur-Mer has Europe's largest fishing port; its market sells fresh turbot and scallops. Honfleur's Vieux Bassin is lined with artisan galleries selling marine paintings.

The route uses the M20 from London to Folkestone, then the A16/E402 along the French coast. Toll sections: A16 near Boulogne (€5.60) and A29 near Le Havre (€9.10). Fuel costs: about €80 for petrol, €60 for diesel.

• Best fuel stops: Cite Europe petrol station (Calais) and TotalAccess at Aire de Villers Carbonnel.
• Tunnel booking: flexible fares start at £85; ferries from Dover at £60.

Driving on the right in France is straightforward but requires attention at roundabouts. Speed limits: 130 km/h on motorways, 110 km/h on dual carriageways. Radar detectors are illegal; use Waze for mobile cameras.
