• Best stops Aix-en-Provence to St. Moritz: Grasse for perfume, Monaco for glamour, Verdon Gorge for kayaking, and Lake Como for elegance.

Road quality is excellent on motorways but variable on Alpine passes. Toll roads are well-lit; secondary roads may lack lighting. Safety tips: always keep headlights on in tunnels (long tunnels like Mont Blanc and San Bernardino). Carry snow chains in winter (October–April).

• Family-friendly: Le Village des Automates (interactive museum) near Aix, Aquarium of Genoa (one of Europe's largest), and Swiss Transport Museum in Lucerne (detour 1.5h).
• Pet-friendly: Several rest areas with green patches; near Menton, there's a dedicated dog park off the A8. In Switzerland, many mountain restaurants allow dogs on terraces.
• Fatigue management: Take breaks every 2 hours. Recommended rest zones: Aire de Port Grimaud (France, with sea view), Autogrill Serravalle (Italy, with shops), and Raststätte Mettlen (Switzerland, family-friendly).
• Nap spots: Park at designated truck stops or well-lit motorway services; avoid unsafe roadside parking.

The route begins on the A8 west of Aix, continuing to the A55 toward Nice. From Nice, take the A8/E80 east to Ventimiglia, Italy, then switch to the A6/E717 heading north through the Italian Riviera. Near Genoa, follow the A7/E25 north towards Milan, then take the A4/E64 east to Bergamo. From Bergamo, take the A2/E35 through the San Bernardino tunnel into Switzerland, following signs to St. Moritz via the A13/E43.

Toll roads are prevalent in France and Italy; carry a credit card or cash. Motorway service areas are well-spaced every 30–40 km. Toll costs: approx. €40 total. Fuel stations are frequent, but in higher Alpine sections they are sparser—fill up before climbing.

• Fuel costs: Estimate €60–€80 for a compact car, depending on driving style. Mountain driving increases consumption.
• Efficiency tips: Use cruise control on highways; shift to lower gears for descents to save brakes and fuel.
• Petrol stations: Major brands (Total, Eni, Agip) near highways; some remote Swiss stations may close early.
• Sleeping options: Overnight in Chamonix or Interlaken for a 2-day break.
