• UNESCO World Heritage Sites: None directly on the main route, but Dijon (30 min detour) has the Historic Site of Dijon (part of Climats of Burgundy).
• Local commerce: Stop at Forges de Py (ironwork) near Dole, or buy Burgundy cheese (Époisses) at roadside markets.
• Climatic conditions: In autumn, morning fog common near Dole; summer sunsets over the vineyards near Troyes are spectacular.

The route is almost entirely motorway, with toll sections in France: from the Swiss border near Geneva to Dijon, expect tolls totaling around €25. Fuel stations are frequent every 30-40 km, but premium diesel (B7) is common.

• Estimated fuel cost for a standard sedan (7 L/100 km): €50-€60.
• Recommended fuel stop: Aire de Pouilly-en-Auxois (near Dijon) has competitive prices.
• No tolls in Switzerland; French tolls can be paid by card or cash at booths.
