Dijon to Treviso Road Trip Guide: Scenic Route via Alps

The A31 from Dijon to the Swiss border passes through the historic town of Dijon, where the first speed camera on the A31 near exit 5 monitors the downhill stretch toward the Saône valley. This route covers approximately 750 km (466 miles) and typically takes 7 to 8 hours of driving time without stops. The journey crosses three countries: France, Switzerland (or Italy via the Mont Blanc tunnel), and Italy, culminating in the Veneto region. The key decision is whether to take the direct motorway route via the tunnel or opt for a more scenic Alpine pass.

• Starting point: Dijon, capital of Burgundy, at the junction of A31, A38, A39.
• End point: Treviso, just north of Venice, served by A27 and A4.
• Best stops Dijon to Treviso include Lake Geneva, the Swiss Alps, and the Aosta Valley.
• How long to drive Dijon to Treviso: around 7-8 hours non-stop, but plan for 10-12 hours with breaks.
• Is it worth driving Dijon to Treviso? Absolutely, for the freedom to explore alpine passes and hidden villages.

The primary route uses the A39 from Dijon to the Swiss border, then joins the Swiss A1 toward Geneva. From Geneva, take the A40 (Autoroute Blanche) toward Chamonix and the Mont Blanc tunnel (toll: around €46 one-way). After exiting the tunnel, take the Italian A5 motorway to Aosta, then continue on the A5 to Turin, and finally the A4 to Treviso. Alternative route: go through the Brenner Pass (A22) via Switzerland and Austria, which is longer but often less congested.

• Tolls: French A39/A40 (approx €25), Swiss vignette required (€40 for 1 year), Mont Blanc tunnel (€46), Italian A5/A4 (approx €30). Total: around €140.
• Fuel costs: petrol stations frequent on French and Italian motorways. Avoid Swiss motorway stops for fuel; towns just off exits are cheaper.
• Rest stops: Every 20-30 km on French/Italian motorways. Notable: Aire de la Bresse (France), Autogrill Chavannes (Switzerland), Area di Servizio Verbano (Italy).

Road quality: excellent on French motorways, good to excellent on Swiss A1, variable on Italian A5 (some tunnels with narrow lanes). The Mont Blanc tunnel is single bore with speed limit 70 km/h and strict safety rules.

The journey transitions from the rolling vineyards of Burgundy to the Jura foothills, then the spectacular alpine scenery around Mont Blanc. After the tunnel, the Aosta Valley offers Roman ruins and castle-dotted hills. Entering the Po Plain, the landscape flattens into agricultural lands and industrial suburbs of Turin, Milan, and finally Treviso. Things to do between Dijon and Treviso include hiking near Chamonix, visiting the thermal baths of Pré-Saint-Didier, and sampling wines in the Franciacorta region near Brescia.

• UNESCO World Heritage Sites: Historic Centre of Dijon (starting point); Lavaux Vineyard Terraces (Switzerland, near Lausanne; detour of 30 mins); Monte San Giorgio (Switzerland/Italy border, near Chiasso); The City of Vicenza and the Palladian Villas of the Veneto (near Treviso).
• Hidden off-route spots: The medieval village of Pérouges (Ain, France) just off A42; the suspension bridge of La Balme de Thuy; the Rocca di Manerba on Lake Garda.
• Local commerce: Dijon’s Les Halles market (sat mornings); Swiss chocolate shops in Montreux; Italian food markets at the Mercato di Piazza dei Signori in Treviso.

Climatic conditions vary: mild in Dijon (spring/fall average 12-18°C), cold and possibly snowy at Mont Blanc passes (winter), Mediterranean-influenced on the Italian plains (hot summers). Route aesthetics peak in the Alps and Lake Geneva region.

The route is generally safe, but note that the Mont Blanc tunnel requires headlights on, no overtaking, and a minimum following distance of 150m. Winter tires or chains are mandatory on the Italian side from November 1 to April 15. Rest zones are well-marked: the Aire de l'Ain (France) has a playground; Swiss rest stops often have picnic areas with lake views; Italian Autogrills are family-friendly with clean bathrooms. Fatigue management: stop every 2 hours or 200 km. Recommended stops for children: Parc de la Tête d’Or (Lyon) is a large urban park with a zoo; Swiss Transport Museum in Lucerne; and the MuBa museum in Aosta.

• Pet-friendly framework: Many French and Italian motorway services allow dogs on leads. The Mont Blanc tunnel requires pets to be in a carrier or on a leash. Accommodation: try the Camping des Gorges du Tarn (not on route) but for direct route, Le Colibri at Servoz (near Chamonix) accepts pets.
• Infrastructure safety: Emergency phones every 2 km on French motorways, every 1 km in the Mont Blanc tunnel. Italian A5 has SOS columns. Roadside assistance: France’s Vinci Autoroutes (call 3605), Swiss TCS (140), Italian ACI (803 116).
• Hidden off-route spots: The Abbaye de Hautecombe on Lake Bourget; the stunning viewpoint at Grand Saint Bernard Pass; the medieval town of Ivrea in Italy.
