Interlaken to Alghero Road Trip: Alps to Mediterranean

The A9 motorway from Interlaken to Simplon Pass was originally a Roman mule track, and today it forms the first leg of a 760-kilometer journey ending at Alghero's Catalan-Aragonese walls. This route crosses three countries, passes through the world's longest railway tunnel (Gotthard Base Tunnel), and ends on an island where the local dialect still preserves 14th-century Catalan phrases.

The drive from Interlaken to Alghero takes approximately 9 hours without breaks, but we recommend splitting it over two or three days to fully experience the transition from alpine meadows to Mediterranean maquis.

The alpine stretch from Interlaken to Brig passes through the Jungfrau region, with views of the Eiger north face. Between Brig and Domodossola, the Simplon Pass road (SS33) winds past ancient stone bridges and waterfall-carved gorges – a UNESCO tentative site for its historic road engineering.

• Swiss National Park buffer zone: near Zernez, chance to see ibex and golden eagles.
• Italian Piedmont vineyards: Barbaresco and Barolo regions accessible via A33 exit at Alba – local wineries offer free tastings.
• Alghero's coral reef: protected marine area, snorkeling spots at Capo Caccia.

Commerce along the route includes Swiss chocolate shops in Interlaken, outlet malls in Serravalle Scrivia (A7 near Genoa), and Sardinian artisan cheeses in Alghero's market. The town of Bosa, 40 km south of Alghero, produces unique hand-painted ceramics.

Local specialties to buy: Ghirardelli chocolate in Interlaken, pesto in Genoa, bottarga (cured fish roe) in Alghero.

Swiss motorways have strict speed enforcement (120 km/h) with average speed cameras on A9. Italian autostrade allow 130 km/h, but sudden fog patches near Genoa require caution. Sardinian roads are generally well-maintained but winding near Alghero's coast.

• Rest zones every 30 km on A7/A9: 'Sosta' areas with picnic tables, clean toilets, and playgrounds.
• Pet-friendly stops: Agip petrol stations in Italy usually allow dogs inside; Swiss rest stops have designated dog areas.
• Family activities: Zoom World amusement park near Lainate (A9), Aquarium of Genoa (Europe's largest), Neptune's Grotto in Alghero.

Fatigue management: The drive features monotone stretches on the Italian A7. Top tips: take coffee breaks at Autogrill Villata (famous for cappuccino and cornetto), switch drivers every 2 hours, and use the ferry crossing as a sleep opportunity.

Hidden off-route spot: The Sacro Monte di Domodossola, a UNESCO site with nine chapels, is a 20-minute detour from the Simplon tunnel exit – quiet and contemplative.

The most efficient path uses the A8/A9 from Interlaken to Milan, then the A7 to Genoa, followed by a ferry to Sardinia. An alternative is driving through Switzerland via Gotthard pass (open June-October) to avoid Milan traffic. Fuel costs average €0.20/km for a diesel car; Switzerland requires a vignette (CHF 40) for motorways, and Italy has tolls approximately €0.08/km.

• Swiss petrol stations near Interlaken: Migrol at 2.00 Fr./l, open 24h on A8.
• Italian autogrills along A7: Villata Ovest, Serravalle Scrivia – both have free Wi-Fi and EV charging.
• Sardinian roads: SS131 from Porto Torres to Alghero is mostly dual carriageway, speed limit 110 km/h.

For the how to find the best stops and hidden gems between cities, we recommend planning a stop in the Ticino region for chestnut risotto and a dip in Lago Maggiore.
