Delft to Colmar-sur-Mer: A Road Trip Through Dutch and French Countryside

The route from Delft to Colmar-sur-Mer traverses 360 kilometers across three countries and two distinct cultural landscapes. This road trip begins in the Dutch province of South Holland and ends on the French Opal Coast near Calais, passing through Belgium and the northern French region of Hauts-de-France.

A curious historical detail: the A16 motorway in Belgium follows the path of the ancient Roman road Via Belgica, which connected Cologne to Boulogne-sur-Mer. Today, this corridor is a modern artery carrying travelers between the Low Countries and the English Channel.

Local driving quirk worth noting: in Belgium, speed cameras are often mounted on orange poles, especially in the Walloon region. The speed limit on Belgian motorways is 120 km/h, but it drops to 90 km/h on the A7 between Tournai and Lille during peak hours.

The primary route uses A4 (Netherlands), E19/E42 (Belgium), A7/E17 (France), and then A16/E402 to the coast. Driving time is approximately 4 hours 45 minutes without stops, but plan for 6 to 7 hours with breaks.

Tolls apply in both Belgium and France. In Belgium, the Liefkenshoek tunnel near Antwerp charges €5.30 for cars. French tolls from Lille to Calais cost about €12.40. An electronic toll badge (like Tolltickets or Bip&Go) can streamline payment.

• Fuel costs: €0.95/L in Belgium, €0.90/L in France as of 2025. Fill up in Belgium before entering France.
• Rest areas: Aire de Ghyvelde (France) features a panoramic view of the Dunkirk beaches.
• Road quality: Dutch and Belgian motorways are well-maintained. French A16 is good but watch for construction near Calais.

The route is generally safe, but be cautious on the Antwerp ring road (R1) which can be congested. In France, the A16 has long straight sections that can induce drowsiness; take breaks every 2 hours.

Family-friendly stop: Pairi Daiza zoo near Mons (Belgium) is world-class. For children, the Citadelle de Lille has playgrounds and a zoo.

• Pet-friendly framework: Most rest areas allow dogs on leash. In France, check that restaurants have pet-friendly patios.
• Fatigue management: Aire de Saint-Martin-Boulogne has a Michelin-starred restaurant. Aire de Tatinghem has a playground.

The first hour from Delft passes through flat polders and green pastures. Near Antwerp, the landscape transitions to the Scheldt estuary. In France, the A16 skirts the coast, offering views of the English Channel.

Hidden off-route spots: The Parc Naturel Régional des Caps et Marais d'Opale has rolling hills and medieval villages like Licques. For birdwatching, the Réserve Naturelle du Platier d'Oye is superb.

• Natural attractions: Platier d'Oye Reserve, Cap Blanc-Nez, Cap Gris-Nez.
• Local commerce: In Saint-Omer, visit the Maison du Maroilles cheese. In Gravelines, the weekly market sells fresh seafood.
