Saint-Malo to Davos Road Trip: Ultimate Guide

The road from Saint-Malo to Davos covers 850 kilometers, crossing northern France, the Jura, and the Swiss Alps. A historical fact: the first section follows the route of the ancient Roman road from Condate (Rennes) to Vesontio (Besançon), now part of the A84 and A36. Driving time is 8.5-10 hours without stops, but the journey is best stretched over two days. Is it worth driving Saint-Malo to Davos? Absolutely, for the contrast of tidal coastlines and Alpine peaks. This guide answers how long to drive, lists things to do between, and highlights the best stops.

Route A84/A36 from Saint-Malo to Basel is tolled (approx. €45 for cars). Switzerland requires a vignette (€40) for motorways. Fuel costs: €90-100 total for a petrol car.

• Best refuel stops: near Rennes (Leclerc), Besançon (Intermarché), and Basel (Tankstelle).
