Canterbury to Sion Road Trip: Ultimate Across-Channel Guide

This road trip begins at the historic city of Canterbury, famous for its UNESCO-listed cathedral, and ends at Sion, the capital of Valais in Switzerland, nestled in the Rhône valley. The total driving distance is approximately 950 km (590 miles) via the most direct route, which takes you through the Channel Tunnel (Eurotunnel) from Folkestone to Calais. Expect a total driving time of about 10–11 hours, excluding stops. A unique feature of this route is the transition from driving on the left (UK) to the right (France and Switzerland) immediately after the tunnel.

The journey blends English countryside, French autoroutes, Swiss alpine roads, and is rich with cultural and natural highlights. Key highways include the M20 (UK), A16 (France), A26, A5 (France, then Switzerland's A1, A9). This guide follows the route Calais–Reims–Dijon–Lausanne–Montreux–Sion. For deeper insights on finding stops, refer to this resource: how to find the best stops and hidden gems between cities.

Road quality is excellent throughout, but be aware of differences: UK roads have a speed limit of 70 mph (113 km/h); France has 130 km/h (110 km/h in rain); Switzerland has 120 km/h on motorways. In Switzerland, headlights must be on at all times (even daytime). Check your car's equipment: a warning triangle and hi-vis vests are mandatory in France and Switzerland.

For family stops, consider the following:

• Reims: Covered carousel in the town square and the Planetarium
• Saint-Dizier: The Lake Der-Chantecoq offers birdwatching and beaches
• Dijon: Jardin des Sciences (science museum) and parks
• Vallorbe: Les Grottes de Vallorbe (caves) with guided tours
• Montreux: Playground near the lakeside and visit the local water park

Fatigue management plan: Stop every 2 hours. Recommended rest areas include: Aire de la Haute Seine (A5, near Langres) with picnic tables; Aire de l'Ain (A40) with panoramic views; and the Swiss rest areas (Raststätte) like Genève-Sud. Consider a two-night layover in Reims and Dijon to break the journey.

The journey begins at the A2 in Canterbury, leading to the M20 towards Folkestone. The Eurotunnel crossing to Calais takes about 35 minutes. It's essential to pre-book your crossing, as last-minute tickets are significantly more expensive. From Calais, follow the A16 to the A26/E17 towards Reims. This toll road is well-maintained but requires a toll pass (like Liber-t) or cash payment. The A26 through Champagne is scenic but can be windy.

After Reims, continue south on the A26/A5 towards Dijon. This section is also tolled, with rest areas every 30–40 km. The A5 offers smooth driving, but watch for speed cameras, especially near Troyes. From Dijon, proceed onto the A36 to the A39 towards Lausanne. Near the border, you'll join the Swiss A1 at Vallorbe. Swiss motorways require a vignette (annual sticker, CHF 40) for cars. You can purchase it at border crossings or gas stations.

• Toll costs: UK to Calais: £130 (Eurotunnel); France tolls: approx. €70–90 total (depending on segment use)
• Fuel: Estimated cost €120–€150 for petrol, based on average consumption (8 L/100km)
• Swiss vignette: CHF 40 (available at border, valid for calendar year)
• Parking: Sion has paid parking garages (e.g., Parking de la Gare) costing about CHF 2 per hour

The drive showcases three distinct landscapes: the rolling hills of Champagne, the Burgundy countryside, and the Alps. Near Reims, the vineyards of Champagne are a must-see. In Burgundy, the landscape is dotted with historic châteaux and vineyards. Watch for the famous Route des Grands Crus near Dijon. As you approach the Jura mountains, the scenery becomes more forested and rugged. The final leg along Lake Geneva (Lac Léman) from Lausanne to Montreux offers breathtaking views of the lake and the Alps.

Local commerce along the route includes: champagne houses in Reims (e.g., Taittinger, Veuve Clicquot), mustard shops in Dijon (Maille), and Swiss chocolate shops in Montreux. In the Swiss Rhône valley, look for local cheese (Raclette, Fondue) and wine (Fendant). A recommended stop is the Lavaux Vineyard Terraces (UNESCO) between Lausanne and Montreux, where you can taste local wines with lake views.

• Reims: Visit the Cathedral of Notre-Dame (UNESCO) and try a glass of Champagne at a local maison
• Dijon: Walk the city center, sample Burgundy wines and mustard
• Lausanne: Stop at the Olympic Museum or stroll the old town
• Montreux: Explore the Chillon Castle
• Sion: Visit the Valère Basilica and Tourbillon Castle
