Colmar to Silkeborg Road Trip: Scenic Drive Across Europe

The drive from Colmar to Silkeborg crosses three countries and 900 kilometers of evolving landscapes. The route begins on the A35 in France, merges onto the A5/E35 in Germany near Freiburg, then follows the A5 north to the A7/E45 near Kassel, continuing into Denmark via the E45/E20 across the Storebælt Bridge—a fixed link connecting the Danish islands of Funen and Zealand. This exact stretch includes the unique experience of driving on a bridge-tunnel combo where the motorway dips under the sea at the Eastern Tunnel, reopened in 1998 after a major safety upgrade.

Colmar lies at 48.08°N, 7.36°E, while Silkeborg sits at 56.17°N, 9.55°E, a shift from temperate oceanic to a more continental-humid climate. The total driving time without breaks is about 8.5 hours, but a minimum of 2 days is recommended to enjoy the stops. The best stops Colmar to Silkeborg include the medieval towns of Rothenburg ob der Tauber (detour from A7) and the Hanseatic city of Lübeck (on route). How long to drive Colmar to Silkeborg non-stop? Approximately 8 hours, but rest stops are essential. Is it worth driving Colmar to Silkeborg? Absolutely, for the dramatic geographic shifts and cultural contrasts. Things to do between Colmar and Silkeborg are abundant: visit the Viking Ship Museum in Roskilde (just off the E20) or explore the Wadden Sea National Park (UNESCO site near the Danish border).

The A5 and A7 in Germany have sections without speed limits, requiring constant attention. Night illumination is good along these Autobahns, but in Denmark, some stretches of the E45 near Billund have limited lighting. The Storebælt Bridge has high wind warnings; in gusts over 20 m/s, speed limits drop to 80 km/h. For pet-friendly breaks: Rasthof Holle (A7 exit 65) has a designated dog walking area with grass and waste bags.

For families, the Legoland Billund (Denmark) is a 30-minute detour off the E45 exit 69 near Vejle. In Germany, the Erlebnis-Zoo Hannover (Hannover Adventure Zoo) is accessible from the A7 exit 54, and the Phaeno science center in Wolfsburg (A2/A39 junction) offers interactive exhibits. Hidden off-route spots: the abandoned village of Altjessnitz (Saxony-Anhalt) near the A9 (far east) is not on this exact route, but a more local gem is the ruined castle of Burg Greifenstein near Bad Wildungen (5 min from A49, which connects to A7). Fatigue management: take a nap at the Raststätte Steinhuder Meer (A7 exit 49) which has a quiet lounge, or use the driver's rest cabin at the Tank & Rast service area near Gørlitz (A7 exit 68) in Denmark. Recommended overnight stops: Göttingen (A7 exit 72) or Kolding (E20 exit 62).

Climatic conditions: The drive through Alsace in spring (March-May) offers mild temperatures and flowering vines. The Rhine valley can have morning fog in autumn. In the North German Plain, strong crosswinds are common, especially on the approach to Hamburg. The best sunset spot is on the Storebælt Bridge, looking west over the Great Belt; stop at the Halsskov service area (before the bridge) for a walk along the shore. Sunsets here in June occur around 9:30 PM CEST, casting golden light on the Baltic Sea.

The journey primarily uses toll-free highways in Germany and Denmark, but France's A35 near Colmar requires a vignette for sections south of Strasbourg (the A35 itself is free north of Mulhouse). Fuel stations are abundant, with Autohofs (truck stops) every 30-50 km along the A5 and A7 in Germany. In Denmark, tankstations are less frequent but well-marked; the last fuel stop before the Storebælt Bridge is on Funen, and the bridge toll (around €50 for a standard car) can be paid with a credit card at the booth.

Fuel efficiency varies: the flat terrain of northern Germany and Denmark reduces consumption compared to the slight hills in Alsace. For a diesel car averaging 6 L/100 km, total fuel cost at current prices (~€1.50/L diesel in Germany) is about €81 for the 900 km. Tolls: only the Storebælt Bridge (approx. €50) and potentially the Great Belt Fixed Link if using the older route. No vignettes are required for Denmark's motorways. The total cost of tolls and fuel combined can be estimated at €131. For detailed costs, visit the official toll calculator for Storebælt.

• Fuel stations: Shell, Aral, and Jet along German Autobahns; Circle K and OK in Denmark.
• Recommended refueling points: Near Würzburg (A7 exit 102), near Hamburg (A7 exit 26), and Kolding (E20 exit 61).
• Motorway service areas: The Rasthof Brohltal (A5) and Rasthof Kassel-Nord (A7) have family-friendly facilities.

The drive begins in the Vosges foothills, with Colmar's half-timbered houses and vineyards. As you join the A5 north, the landscape flattens into the Upper Rhine Plain, offering views of the Black Forest to the east. The transition near Frankfurt marks the start of the Central German Uplands, and the A7 cuts through rolling hills and forests, passing the Spessart and Rhön regions. North of Kassel, the terrain opens into the North German Plain, a flat agricultural expanse stretching to the Danish border.

In Denmark, the E45 crosses the Jutland Peninsula, punctuated by heathlands and winding streams. Near Silkeborg, you enter the Søhøjlandet (Lake Highland) region, with over 100 lakes and the Gudenå River. The geological shift from glacial moraine to limestone formations is evident in the clear waters. A short detour to the Himmelbjerget (Sky Mountain) offers a 147 m elevation with panoramic views—the highest natural point in lowland Jutland.

Local Commerce & Culture

• Alsace (Colmar region): Visit a roadside stall for Munster cheese and Gewürztraminer wine. The Route des Vins d'Alsace runs parallel to the A35 for a short stretch.
• Franconia (near Würzburg): Stop at a Bauernmarkt (farmer's market) for Fränkischer Grünkohl (kale) and local sausages.
• Danish border area (Padborg): Salling SMV supermarket sells Danish pastries and smørrebrød ingredients.
• Silkeborg area: Hærvejen, an ancient military road, hosts local craftspeople selling wood carvings and woolens. Try the smoked trout from Gudenåen Fiskepark.

UNESCO World Heritage Sites

Two UNESCO sites are near the route with a short detour: The Wadden Sea (Denmark/Germany) accessible from the E20 near Esbjerg (60 km detour) and the Hanseatic City of Lübeck (Germany) directly off the A1 (10 km detour from the A7). Additionally, the Bergpark Wilhelmshöhe in Kassel (UNESCO) is a 10-minute drive from the A7 exit 63.
