Interlaken to Kiel Road Trip: Ultimate Guide

This road trip connects the Swiss Alps with Germany's Baltic coast, covering roughly 1,000 kilometers via the A1, A5, and A7 motorways. Driving time is about 10 hours without stops, but you'll want to budget at least two days to explore.

The route crosses six German states, showcasing dramatic changes in landscape and culture. It passes through the Black Forest, the Rhine Valley, and the North German Plain. A little-known fact: the A1 near Hamburg has Europe's longest continuous highway, the 55-km Elbtalbrücke section.

From Interlaken's turquoise lakes to the Black Forest's dense woods, every region offers distinct beauty. The Rhine Valley introduces vineyards and castle ruins; near Göttingen, the Leine river meanders through farmland. As you approach Kiel, the landscape flattens into the Holstein Switzerland lake district.

• UNESCO sites: Old Town of Bern (detour), Upper Middle Rhine Valley, Wartburg Castle near Eisenach.
• Between Kassel and Göttingen, stop at the Fairy Tale Road for themed towns.
• Local commerce: Sample Black Forest ham, Swabian Maultaschen, or Lübeck marzipan.

Weather varies: Alpine passes may be snowy until May; North German summers are mild. Spring and autumn are ideal for driving. In summer, the A7 can be congested due to holiday traffic.

The optimal route uses A8 from Interlaken to Basel, then A5 north to Frankfurt, A3/A7 to Kassel, and A7 toward Kiel. Expect heavy traffic around Frankfurt and Hamburg. Avoid Friday afternoons and holiday weekends.

Fuel costs vary: Switzerland ~€1.8/liter, Germany ~€1.6. Autobahn rest stops (Raststätte) have higher prices—fill up at Aral or Shell stations near exits. Consider a vignette for Swiss highways (€40 for 10 days).

German autobahn has many no-limit sections, but also variable speed limits. Always obey digital signs. Swiss roads require dipped headlights day and night. Rest every 2 hours; use Rastplätze with picnic tables.

• Family-friendly: Phantasialand near Cologne, Sea Life in Timmendorfer Strand (near Kiel).
• Pet-friendly: Many rest stops have grass areas; Germany requires dogs on leash. Swiss rest stops are less accommodating.
• Hidden off-route spots: The Sababurg forest near Kassel (Sleeping Beauty castle) and the Molfsee open-air museum near Kiel.

For fatigue management, especially on long A7 stretches, take the Hildesheim exit for a short walk at the restored Roemer- und Pelizaeus-Museum. Local food truck stops like 'Grillstation' offer quick, tasty breaks.
