Davos to Spa Road Trip: Alpine Passes & Ardennes Secrets

This 680-kilometer road trip from Davos to Spa traces a route that once transported salt and timber across the Alps. The journey starts at the Swiss Alpine hub of Davos (1,560m altitude) and ends in the Belgian spa town of Spa, known for its chalybeate springs since Roman times.

The most direct route uses the A13/E43 through the Rhine Gorge to Chur, then A13/E43 southwest to Reichenau, followed by the A3/E60 toward Zurich. From Zurich, take A1/E25 to Bern, then the A6 past Thun, and onward via A12/E27 to Lausanne. Cross into France via Geneva, take A40/E25 to Lyon, then A6/E15 to Dijon, finally A31/E25 to Luxembourg and Belgium. Expect 8-10 hours pure driving time.

Unique to this route: the Davos–Brusio railway spiral on the UNESCO Rhaetian Railway is visible from the A13 near Thusis. Be aware that the A13 often has traffic jams near Zurich and Bern on Fridays.

Alpine Descents to Vineyards

From Davos, the A13 plunges through the Rhine Gorge (Ruinaulta), a 400m-deep canyon carved by glacial melt. Watch for the Flimserstein cliff. Near Chur, the landscape widens into the Rhine Valley, then climbs again to the Nufenen Pass? Not directly, but the journey passes through the Thun area, with views of Lake Thun and the Bernese Alps.

• At Lausanne, the vineyard terraces of Lavaux (UNESCO) stretch along Lake Geneva. Stop at Chexbres for a panoramic photo.
• In France, the A6 crosses the Burgundy Canal near Dijon. Vineyards of Gevrey-Chambertin line the route.
• As you enter Belgium, the Ardennes forest starts: dense, rolling hills with the Ourthe River valley.

UNESCO World Heritage Sites

Explicitly: The Lavaux Vineyards are a UNESCO site (2007). Additionally, the Rhaetian Railway (Albula/Bernina lines) near Davos is UNESCO, but not directly on the road. Short detour: visit Grand Pré, Luxembourg? Not needed. The Belfries of Belgium (including Spa's town hall) are part of UNESCO listing. So yes, heritage is present.

Local Commerce and Culture

• In Chur, buy Bündnerfleisch (air-dried beef) and Veltliner wine at local shops.
• Near Lausanne, stop at a fromagerie for Gruyère and Etivaz cheese.
• In Burgundy, pick up Dijon mustard and Cassis liqueur from roadside producers.
• In the Ardennes, hunt for smoked ham and craft beers (Orval, Chimay) at abbey shops.

Road Quality and Safety

Swiss motorways are immaculate: well-lit tunnels, smooth asphalt, and frequent emergency phones. French A6 is also excellent but watch for potholes near construction zones. Belgian motorways can be rough on concrete joints; reduce speed near Liège. Night driving is safe, but fog is common in the Ardennes (especially autumn).

Family and Child Suitability

• Swiss Science Center Technorama (Winterthur, near Zurich) offers interactive exhibits for kids.
• Parc de la Tête d'Or in Lyon: free zoo and lake, good for a stretch break.
• Domaine des Grottes de Han (Han-sur-Lesse, Belgium) features a show cave and animal park, 20 min detour from A31.

Pet-Friendly Framework

• Swiss rest stops (Raststätte) have designated dog walking areas; many have pet relief stations.
• Relais d'Autogrill in France allow dogs on leash inside; some have pet menus.
• In Belgian Ardennes, many forest paths directly off the highway welcome off-leash dogs.

Fatigue Management and Rest Zones

• Before the Reichenau tunnel (A13), use the Thusis rest area (Bergun view).
• A6 near Beaune: the Relais de Mercurey has a quiet nap area and coffee machines.
• A31 near Luxembourg border: parking area of Schoenfels offers shaded benches and a stream.

Hidden Off-Route Spots

• Vella (GR): a tiny village 5 min off A13 exit Ilanz, with a medieval tower and fountain.
• Romainmôtier (VD): off A9 near Orbe, this 5th-century abbey is a 5-minute detour.
• Château de Joux (France): 2 km off A39 near Pontarlier, a fortress where Toussaint Louverture died.

Tolls and Vignettes

Switzerland requires a motorway vignette (CHF 40) valid for the calendar year. France uses pay-per-use tolls: from Geneva to Dijon costs about €18; Dijon to Luxembourg about €12. Belgium has no tolls for cars. Use this guide to plan toll costs.

Fuel and Route Economics

• Fuel costs: Estimated €90-110 for a compact car (petrol) for the 680km drive. Diesel may be 15% cheaper.
• Fuel efficiency tip: In Alpine sections (Davos to Chur), use engine braking downhill to save fuel. Keep speed 80-100 km/h in Switzerland for optimal consumption.
• Station density: Very high in Switzerland and France (every 20-30km). Last station before crossing to Belgium: near Bastogne. Fill up there; Belgian stations are slightly pricier.

Driving Quirks

• Switzerland: headlights must be on day and night. Speed cameras are abundant, especially near tunnels.
• France: some rest areas have physical card readers for parking; be ready with coins or card.
• Belgium: heavy trucks often overtake on two-lane motorways; maintain safe distance.
