Santander to Interlaken Road Trip Guide: Scenic Drive Through France and Switzerland

The Santander to Interlaken drive spans approximately 1,100 kilometers (684 miles) and takes about 11-12 hours of pure driving time, excluding stops.

A unique geographical quirk: you'll cross the Jura Mountains near the French-Swiss border, where the road briefly enters a 2.5 km tunnel beneath the Col de la Givrine, a pass that historically separated the Kingdom of France from the Swiss Confederacy.
