Cagliari to Thun: Epic Mediterranean to Alpine Road Trip

This road trip from Cagliari (Sardinia) to Thun (Switzerland) spans over 1,200 km and includes a ferry crossing from Sardinia to mainland Italy, plus a transit through the Swiss Alps. The drive combines coastal Mediterranean roads, the Po Valley's straight highways, and the dramatic ascent into the Bernese Oberland. A unique fact: the route crosses the 46th parallel north twice – once near Genoa and again just south of Thun – but the landscape changes from olive groves to alpine meadows in just two days.

The journey requires careful planning due to the ferry leg and alpine tolls. The fastest route from Cagliari to Genoa is via the SS131 and SS291, then a ferry (Grimaldi or Tirrenia) to Genoa or Livorno. From the mainland, take the A7 motorway from Genoa to Milan, then A1 to A8 toward Switzerland, followed by the A2 to Thun. Total driving time on land is about 5.5 h after the ferry, but the overall trip including ferry and breaks easily takes 18–20 hours.

• Tolls: The A7/A1/A8 in Italy are toll roads; expect about €25–€30. Swiss autoroutes require an annual vignette (CHF 40).
• Ferry: Cagliari–Genoa overnight ferry saves a night's accommodation; car included. Book in advance for summer.
• Fuel stops: Frequent along Italian motorways (every 30 km), but less dense in the Apennines near Genoa.

The geographical shift from Sardinia's rugged coastline to the Po Valley's flat farmlands, then the sudden rise of the Swiss Alps, is breathtaking. In Sardinia, you'll see limestone cliffs and macchia scrub; the ferry crossing offers views of the Ligurian Sea. After Genoa, the A7 climbs through the Apennines with tunnels and viaducts. Once past Milan, the landscape opens to the Po plain, then the Alps near Bellinzona. The final stretch along Lake Thun is postcard-perfect.

• UNESCO Sites: The route's direct path passes none, but a short detour to the Rhaetian Railway in the Albula/Bernina landscapes (UNESCO) is possible near Thusis, about 1 h east of Thun.
• Local products: Near Vercelli (Po Valley) buy riso carnaroli; in the Swiss part, try Berner Alpkäse from roadside farm shops.
• Hidden off-route spots: Just off the A7 near Busalla is the abandoned village of Savignone (5 min exit), home to a medieval castle ruin.

Road quality is excellent on Italian autostradas and Swiss highways, but the Apennine stretch has frequent tunnels and sharp curves – reduce speed. Night illumination is good on main routes. For families, the Fondazione Sandretto Re Rebaudengo in Turin (near the A4/A5 junction) offers modern art workshops for kids. Pet-friendly stops include Area di Servizio Brianza Sud on the A1, which has a designated dog walking area.

• Fatigue management: Best rest zones: the Novara Ovest service area (A4/A26) has a quiet lounge; in Switzerland, the Gurtnellen rest stop (A2) offers panoramic views ideal for a 20‑min nap.
• Safety tips: Winter tires mandatory in Switzerland from Nov‑Mar; carry snow chains. Italian motorways have speed cameras (autovelox) – respect limits.
• How long to drive Cagliari to Thun? Approximately 16–18 hours of pure driving+ferry, but plan for two days with an overnight near Genoa or Milan.
