Lauterbrunnen to Cagliari: Alpine to Mediterranean Road Trip

The journey from Lauterbrunnen (46.5944° N, 7.9084° E) to Cagliari (39.2238° N, 9.1217° E) spans roughly 850 km and crosses four countries. Few know that the Swiss A8 motorway near Interlaken has a 3.5-km covered avalanche gallery built in 1973. That engineering marvel sets the tone for a route that combines alpine tunnels, Italian autostrade, and a ferry across the Tyrrhenian Sea.

Driving time without stops is about 10–11 hours on land, plus a 13–15 hour overnight ferry from Genoa to Cagliari. This guide breaks down every aspect: landscapes, fuel stops, UNESCO sites, and family-friendly breaks.
