Mulhouse to Rust Road Trip: Alsace to Black Forest

The 85-kilometer route from Mulhouse to Rust begins on the A36 autoroute before merging onto the A5/E35 near the German border. This road trip crosses the Rhine River at Ottmarsheim, where the historic 11th-century Ottmarsheim Abbey (a UNESCO tentative site) stands just off the N66. A local quirk: the A5 is toll-free in Germany, but the French A36 has a toll section north of Mulhouse costing about €2.30 for passenger cars.

Infrastructure safety: Both A36 and A5 are well-lit at night, with emergency phones every 2 km. German sections have no hard shoulder on two-lane segments; use rest areas in emergencies. Speed cameras are common near construction zones.

Family suitability: Europa-Park is the main draw for kids, but along the way, the Burg Rötteln castle (near Lörrach, off A5 exit 66) has a kids’ treasure hunt. The Museum Autovision in Altlußheim (exit 58) with interactive car exhibits is great for older children.

• Pet-friendly stops: Le Grand Chien (Sausheim) has a pet-friendly terrace. At the Hundespielplatz Freiburg (off A5 exit 63), a fenced dog park.
• Fatigue management: Rest area Aire de Sausheim (A36) has shaded parking and picnic tables. Raststätte Freiburg-Süd (A5) offers a nap room (€5/hour).

Hidden off-route spots: The Ruine Baden (abandoned castle above Badenweiler, 10 min from A5 exit 68) offers panoramic views. The Harmoniebrunnen fountain in Village-Neuf (near Saint-Louis) is a quirky 1960s sculpture.

Climatic conditions: In autumn, fog often forms on the Alsatian plain until 10am. The Kaiserstuhl area is known for local wind patterns; sunset from Katzenbuckel viewpoint (near Rust) is spectacular over the Rhine valley.

Geographically, the route transitions from the flat Alsatian plain to the rolling foothills of the Black Forest. The Rhine River acts as a natural border; once crossed, vineyards give way to dense spruce forests. The Kaiserstuhl volcanic massif is visible to the east—a perfect spot for a short detour.

UNESCO World Heritage: None directly on the route, but the Strasbourg Cathedral (1 hour north) is a UNESCO site. The Ottmarsheim Abbey is on the tentative list (2017). A short detour: Jardin des Deux Rives in Kehl (30 min north) is not UNESCO but offers scenic cross-border gardens.

Local commerce: At the border village of Ottmarsheim, a weekly market (Wednesdays) sells Alsatian cheeses and local wine. In Rust, shop for Black Forest cuckoo clocks and smoked ham at the Rust Markt (Saturdays).

• Alsatian wines: Riesling, Gewürztraminer at Domaine Pfister (Ottmarsheim).
• Black Forest honey: at Imkerei Schmitt (Rust, off L113).
• Handmade pottery: Atelier Schelb (Bad Bellingen, 5 min from A5 exit 64).

The A36 autoroute from Mulhouse to the German border is well-maintained with good signage. After crossing the Rhine, the German A5 narrows to two lanes in some sections, especially near Freiburg, but remains in excellent condition.
