Savona to Sion Road Trip: Coastal Pass to Alpine Valley

The drive from Savona to Sion covers approximately 310 kilometers, crossing the Alps via the A6 motorway (E717) through the Fréjus Tunnel. This route transition from the Mediterranean coast to the high alpine valleys of Switzerland. A specific local quirk: the Fréjus Tunnel, inaugurated in 1980, sits at an altitude of 1,298 meters and is one of the longest road tunnels in the Alps, creating a microclimate shift that often surprises drivers with sudden temperature drops.

The journey utilizes the A10 from Savona to Ventimiglia, then the A8/E80 inland, before merging onto the A6/E717 toward the Fréjus Tunnel. Toll costs for the entire Italian section amount to approximately €25, while the tunnel fee is about €50 one-way. Fuel stations are well-distributed along the A6, with major stops at Turin Orbassano and Susa. For electric vehicles, charging points are available at Susa and the tunnel rest area.

• Toll cost: ~€75 total (incl. tunnel)
• Fuel consumption: Expect 7-8 L/100 km on average due to gradients
• Recommended fuel stops: Savona (start full), Turin area (midway), Sion (end)

The route transitions from the Mediterranean maquis of Liguria to the Alpine foothills, passing through the Po Valley's agricultural plains, then climbing the Susa Valley. Key landscape shifts occur near the town of Susa, where dense forests give way to high-altitude pastures. A notable UNESCO World Heritage Site is the Sacri Monti (Sacred Mounts) of Piedmont and Lombardy, particularly the Sacro Monte di Varallo, reachable via a 10-minute detour from the A6 at Borgosesia.

• Must-stop viewpoint: Col de l'Échelle (1,556 m) before the tunnel – alpine panorama
• Local commerce: Buy Toma cheese in Susa or miele di montagna (mountain honey) at roadside stalls near Oulx
• Culinary highlight: Osteria La Torre in Susa offers traditional agnolotti del plin

The A6 is well-maintained with modern asphalt, but the tunnel section requires attention: speed is limited to 70 km/h, and no overtaking is allowed. Night illumination is adequate, but fog can form near the tunnel exits. For family breaks, the Parco del Valentino in Turin is a 15-minute detour with playgrounds and a botanic garden. For pet-friendly stops, the Agriturismo La via del Sale near Cuneo has a fenced dog area and water bowls.

• Fatigue stop: Rest area Villafranca Piemonte (km 270) – picnic tables and quiet zone
• Pet-friendly café: Bar del Tunnel in Bardonecchia – dog welcome on terrace
• Hidden off-route spot: Abandoned village Exilles with a fortress, 5 min from the A6 exit at Exilles
