Metz to Sion Road Trip: Alpine Views & Historic Route

The drive from Metz to Sion covers roughly 350 kilometers, tracing a path from the Moselle River to the Rhône Valley. The journey transitions from French Lorraine's rolling hills into the Swiss Alps, with a mandatory pass through the Jura and the outskirts of Basel. A little-known fact: the route crosses the linguistic border between French and German Switzerland just east of Basel, where road signs switch from French to German. This trip typically takes 4 to 5 hours without stops, but the best stops between Metz and Sion transform it into a full-day adventure.

The road itself is a mix of French autoroutes (A31, A36) and Swiss highways (A1, A9), each with distinct toll systems and speed limits. French autoroutes are tolled, while Swiss highways require a vignette (40 CHF for a year). For scenic detours, consider the Route des Crêtes in the Vosges or the wine routes of Alsace.

Fuel prices vary significantly along the route. In France, expect €1.90/liter for diesel; Switzerland is cheaper at around CHF 1.80/liter. Fill up in Switzerland if possible. The Swiss highway vignette is mandatory – purchase at border crossings or gas stations.
