Colmar to Interlaken: Alpine Road Trip Guide

The drive from Colmar to Interlaken spans approximately 200 km (124 miles) and takes about 2.5 to 3 hours without stops. This route crosses the Franco-Swiss border near Basel and winds through the Jura Mountains before descending into the Bernese Oberland. A historical oddity: the section between Colmar and Mulhouse was once part of the ancient Roman road connecting Argentoratum (Strasbourg) to Augusta Raurica (near Basel). Today, the A35 highway follows this path.

Drivers should note that Swiss motorway vignettes are required and available at border petrol stations. The journey offers dramatic geographic shifts from Alsatian vineyards to Alpine peaks. How to find the best stops and hidden gems between cities is essential for maximizing this route.

The route primarily uses well-maintained highways: A35 in France, then A1 and A6/A8 in Switzerland. Toll sections in France (A35 between Colmar and Mulhouse) cost €2.70 for cars. Switzerland requires a vignette (CHF 40) valid for 14 months. Fuel costs: petrol averages €1.80/L in France and CHF 1.70/L in Switzerland. Diesel is slightly cheaper.

• Fuel stations: Regular intervals of 20-30 km on A35 and A1; fewer on A6/A8 (every 40 km).
• Recommended fill-up: Fill tank before entering Switzerland at Basel border stations (e.g., Tamoil at 47.5608, 7.5914).
• Fuel efficiency: Expect 8-10% lower efficiency due to altitude gain (from 200 m in Colmar to 560 m in Interlaken).
• Rest areas: Aire de Meyenheim (A35, km 27) has clean toilets and vending machines. Swiss Raststätte Deitingen (A1, km 67) offers full services.

Parking in Interlaken is easy: multi-storey car parks near the railway station cost CHF 2-3/h. For free parking, try the eastern outskirts near Unterseen.

The geographical shift is striking. Departing Colmar (Alsace), the land is flat with fertile plains and vineyards. Near Basel, the landscape becomes hilly as you cross the Rhine. The A1 passes through the Jura folds, with scattered farms and dense beech forests. At Solothurn, the Alps emerge on the horizon. The final leg from Bern to Interlaken follows the Aare River valley, with dramatic cliffs and waterfalls.

UNESCO Sites Along the Route

• Grande Île of Strasbourg (45 min detour): 17 km north of Colmar, the historic centre is a UNESCO site.
• Old City of Bern (directly on route): 1-hour stop recommended. The Zytglogge clock tower and bear pit are highlights.

Road surface is excellent on all highways; minor sections of A1 near Bern are being repaved (2025). Night illumination: full lighting on A35 and A1; A6/A8 has reflective markers but no lights in rural segments. Speed limits: 130 km/h France, 120 km/h Switzerland (except highway code in villages). Radar traps common near construction zones.
