• Distance: ~1,200 km (745 miles)
• Driving time: 12–14 hours pure

The journey from Aarhus to Mulhouse traverses four distinct natural regions. In Denmark, the Jutland peninsula features glacial moraines and beech forests. The Wadden Sea UNESCO site near Esbjerg is a detour but offers mudflat hiking. Crossing into Germany, the Flensburg Fjord gives way to the rolling hills of Schleswig-Holstein. The Harz Mountains around Göttingen provide a stark contrast with dense spruce forests. South of Würzburg, the Tauber Valley offers romantic vineyards and half-timbered villages.
