St. Moritz to Mons Road Trip: Alpine Peaks to Belgian Plains

The drive from St. Moritz (1,822 m) to Mons (56 m) drops over 1,700 meters in elevation across 800 km, passing through Switzerland, France, and Belgium. This route crosses the Swiss National Park, the Jura Mountains, and the Champagne region before reaching Mons, a city with a UNESCO-listed belfry.

A local driving quirk: on the Swiss A13, expect pink snow fences that double as avalanche deflectors. In Belgium, the E42 has cobblestone sections near Mons that date to Roman times.

This route uses the A13 in Switzerland, then the French A36, A5, A26, and finally the Belgian E42. Toll roads apply in France (€20-30 total) and Belgium (free). Swiss vignette needed (CHF 40).

• Fuel stations every 30-40 km in Switzerland/France, fewer in Belgian Ardennes
• Diesel recommended for long stretches; petrol okay
• Average fuel cost: €120 for the trip
