Sion to Varenna Road Trip Guide: Alpine Drive

The road from Sion, Switzerland, to Varenna, Italy, crosses the Rhône Valley, climbs the Simplon Pass, and descends into the Italian Lake District. This 220 km journey typically takes 3 hours 15 minutes without stops, but the real value lies in the detours and slow travel. The Simplon Tunnel, opened in 1906, remains one of the longest rail tunnels in the world, but for drivers, the old pass road offers stunning views and historical charm. This guide covers best stops Sion to Varenna, how long to drive Sion to Varenna, and is it worth driving Sion to Varenna? Absolutely, for the dramatic shift from Alpine peaks to Mediterranean lakes.

The route combines major highways (A9 in Switzerland, SS33 in Italy) with local roads. Expect to spend around 4-6 hours with scenic breaks. Planning is key to avoid fatigue and maximize discovery. Use this guide to find things to do between Sion and Varenna, from vineyards to castles.

Road condition is good on both sides, but the Simplon Pass has tight hairpins and occasional gravel patches. In winter, mandatory snow chains from November to April. Italian section has narrow lanes through villages; watch for bikes. Night driving: poor street lighting on pass; use high beams. For families, stop at the Swiss Vapeur Parc in Bouveret (1 hour from Sion) – a miniature railway park. Or at the Adventure Park in Domodossola (treetop climbing). Pet-friendly: Simplon Dorf's Berggasthaus holds a dog-friendly terrace; in Varenna, Ristorante La Vista allows well-behaved dogs. Fatigue management: park at Simplon Hospiz (free, safe) for a 20-min nap. Also, the rest area near Mergozzo (lake view) has benches and shade. Safety tips: always carry water, sun protection in summer; the pass can be cold even in July (15°C). Emergency numbers: 112 in both countries.

For hidden off-route spots: the abandoned stone village of Cravagliana (5 min from SS33 near Varzo) and the Orco Valley viewpoint off the SS394.

The geography shifts from the dry, sunny Rhône Valley to the birch forests of Simplon, then to the lush, terraced hills of Lake Maggiore and Lake Como. The Simplon Pass features the scattered villages of Simplon Dorf and Gondo, where you can find the ancient stockpile route (Barena). The Italian side descends through the Ossola Valley, with vineyards around Domodossola. A must-see UNESCO site: the Sacri Monti of Piedmont and Lombardy (including the one at Ghiffa, near the route) are a short detour (20 minutes from Verbania). Also, the vineyards of the Valtellina (just north of Varenna) are a UNESCO cultural landscape.

Local commerce: at Simplon village, buy Alpage cheese from the cooperative (open June-September). In Domodossola market (Saturday), find salamis and local wine. Near Varenna, olive oil from Lake Como (very green, peppery) is sold at Agriturismo Caresito. The best stop: the Borghetto di Domodossola, a medieval village with cobblestone streets. For hidden gems, take the 5-minute detour from Simplon Pass to Hübschhorn, an abandoned mine with a 360-degree view.

• UNESCO sites: Sacri Monti of Ghiffa (20 min detour), Valtellina vineyards (10 min from Varenna)
• Local products: DOP honey from Sion, Bettelmatt cheese from Simplon, Lugana wine near Varenna
• Best markets: Sion (Wednesday and Saturday), Domodossola (Saturday), Varenna (Sunday morning)

The drive starts on the A9 from Sion towards Brig. After Brig, you have two options: the Simplon Pass (SS33) or the Simplon Tunnel. The pass is 40 minutes longer but offers dramatic views and is free. The tunnel costs 20 CHF per car. In Italy, the SS33 becomes the SS340 to Luino and then the SS394 towards Varenna. Fuel economy: the climb to Simplon (2008 m) reduces efficiency; expect 8-12 L/100 km. Fill up in Sion (cheap Swiss fuel) and again before Varenna (Italian fuel is slightly cheaper). Toll: no tolls on the Swiss side except the tunnel. Italy has no tolls on this route. Three fuel stations on the Swiss side, five after the pass. Parking in Varenna is limited; use the large lot near the ferry terminal (€2/hour).

• Distance: 220 km via Simplon Tunnel, 250 km via pass
• Driving time: 3h15min (tunnel) to 4h (pass)
• Best season: May-October for pass; winter requires snow tires
