Colmar to Mulhouse Road Trip: A Deep Drive Through Alsatian Gems

Did you know the A35 autoroute between Colmar and Mulhouse was built atop a former Roman road connecting Argentovaria (Colmar) to Augusta Raurica (Augst)? This 44-kilometer stretch, normally clocking 30 minutes without traffic, offers far more than a quick transit. The route transitions from the Vosges foothills to the Alsace plain, with the Rhine flanking east and the Sundgau hills south. For those wondering how long to drive Colmar to Mulhouse, the answer is deceptively short, but the question is it worth driving Colmar to Mulhouse becomes moot once you discover the layers of history and nature lurking off the exits. This guide unearths the best stops Colmar to Mulhouse, turning a mundane highway dash into a curated Alsatian journey.

how to find the best stops and hidden gems between cities. This philosophy underpins our deep dive.

The A35 is well-maintained and mostly straight, but watch for heavy truck traffic near Mulhouse. Speed cameras are frequent, especially near exit 23. For night driving, the road is well-lit around towns but dark between. Fatigue management: recommended rest stops include the Aire de Horbourg (picnic tables, clean toilets) and the parking at Parc de Wesserling (exit 18).

• Safety tip: Fog can roll in from the Rhine in autumn–reduce speed.
• Family stop: Le Petit Train at Parc du Petit Prince (exit 21) – interactive museum and playground.
• Pet-friendly: The banks of the Canal du Rhône au Rhin (near exit 20) have a 2-km dog-walking path. Cafés in Ensisheim are pet-friendly (ask for water bowls).

Hidden off-route gem: The ruins of Château de l'Engelbourg (5 min from exit 23) – a medieval castle with panoramic views. For nap safety, pull into a rest area (Aire de Horbourg or Aire de Meyenheim) – both well-lit and patrolled.

As you leave Colmar, the Vosges mountains fade in the rearview, replaced by the vast Alsace plain. Vineyards dominate the flanks near Eguisheim and Wettolsheim, though they're more visible on side roads. The climate is semi-continental: expect misty autumn mornings and hot summers. A notable aesthetic spot is the viewpoint at Château du Hohlandsbourg, 10 minutes east of the A35 near Kaysersberg – perfect for sunset photography.

• Natural landmarks: The Ill river parallels the route near Ostheim; the Route des Vins (wine road) runs parallel to the west.
• Best sunset spot: Côte de Rouffach, overlooking vineyards.
• Local product: Munster cheese farms dot the hills – stop at Ferme des Coteaux (exit 23) for fresh fromage.

Commerce along the route is seasonal. Autumn brings roadside stands selling apples and mirabelle plums. Check the Sunday market in Rouffach for pottery and local honey.

The A35 southbound from Colmar exits smoothly onto the N83 near Sélestat if you miss the autoroute, but stick to the A35 for efficiency. Fuel stations cluster around Colmar (TotalEnergies, Esso) and Mulhouse (Avia, Shell), with a sparse gap near Ostheim. The topography is flat, so fuel efficiency is high—expect ~5 L/100km in a compact car. Estimated fuel cost: €7–9 for the one-way trip. Night illumination is good on the A35, but the D83 alternate is darker and narrower.

• Colmar to Mulhouse driving time: 30 min direct, 1.5 hours with stops.
• Best fuel stop: Leclerc Colmar-Horbourg (cheapest diesel).
• Road surface: Excellent on A35, fair on D83 with some patched sections.

Toll gates? None on this A35 segment; it's a free motorway. However, a vignette is required if you venture east into Germany (exit at Breisach).
