The journey uses the A7/E80 north from Cassis, then the A40/E62 through the Mont Blanc tunnel. In Switzerland, follow the A1/E60 past Geneva to Zurich. From Zurich, the A3/E60 leads to the German A3, finally joining the A92/E56 to Passau. Toll roads apply in France (€0.12/km) and Switzerland (annual vignette CHF40). Fuel stations are abundant on major highways, but sparse on scenic D-roads in the Jura.

• Estimated fuel cost: €80-€120 depending on vehicle (gasoline at €1.80/L in France, €1.90 in Switzerland, €1.85 in Germany).
• Fuel efficiency tip: Use cruise control on flat autoroutes; the Jura climbs can reduce efficiency by 15%. Fill up in Germany for cheaper fuel.
• Station distribution: Every 30-50 km on autoroutes; in rural Jura, stations are limited to towns like Lons-le-Saunier and Dole.

The route transitions from the turquoise calanques of Cassis through the lavender-covered Luberon (detour via D973) and into the Jura's rolling vineyards. The Swiss plateau offers lake vistas near Zurich, before the Black Forest's dense pines near Donaueschingen. The final stretch into Passau reveals the Danube valley's baroque towns.

• UNESCO sites: The route passes near the Lavaux Vineyards (Switzerland), Regensburg's Old Town (Germany), and the Primeval Beech Forests along the Danube.
• Sunset spot: View the sunset from the Jura's Fort l'Écluse (Nantua), where the Rhône valley glows orange.
• Local crafts: Near Lons-le-Saunier, buy Comté cheese at fruitières. In the Black Forest, stop for handcrafted cuckoo clocks in Triberg.

French autoroutes are well-lit and have emergency phones every 2 km. Swiss roads require headlights in tunnels. German autobahns have no speed limit on sections, but traffic jams near Munich especially on weekends. Always carry a reflective vest and warning triangle (mandatory in France and Germany).

• Family-friendly: Visit the Swiss Transport Museum in Lucerne (1h detour) and the Playmobil FunPark in Zirndorf (near Nuremberg). In the Black Forest, the Vogtsbauernhof open-air museum offers hands-on history.
• Pet-friendly: Many rest stops like 'Aire du Bois de la Bâtie' (A40) have dog walking areas. Cafes in Passau's historic district welcome well-behaved pets.
• Rest zones: For a nap, use official rest areas every 20 km. In the A1 near Yverdon-les-Bains, a dedicated 'aire de repos' provides shaded parking and benches. In Germany, 'Raststätte' facilities offer clean restrooms.
