Interlaken to Füssen Road Trip: A Deep Alpine Driving Guide

Leaving Interlaken, you immediately notice the precise road markings on the A8. This section of Swiss highway is known for its strict speed enforcement, with average speed cameras every 15 kilometers. The drive to Füssen spans approximately 450 kilometers, usually taking 5 to 6 hours without major stops.

Historically, this route traces part of the old Roman Via Claudia Augusta, a military road connecting Italy to Germany. Today, you follow the A8, A1, and A96 through three countries—Switzerland, Austria, and Germany.

Along the way, asphalt temperatures can vary by 15°C between Alpine tunnels and open valleys. This affects both fuel economy and tire grip.

Leaving Interlaken, the Jungfrau peaks dominate the rearview mirror. Soon the A8 cuts through the 2.2-km Kirchenwald Tunnel, giving way to Lake Brienz’s turquoise waters. The landscape transitions from Swiss alpine to rolling pre-Alps near Zurich. After crossing into Austria, Lake Constance (Bodensee) appears on your left.
