Strasbourg to Siena Road Trip: A Journey Through Alsace, Alps & Tuscany

This route traces the historic Via Francigena pilgrimage path, but modern drivers follow the A5/E35 corridor through Basel and the Gotthard tunnel. The 850 km journey takes about 9 hours without stops, but you'll want to stretch it over two days.

One little-known fact: the segment between Lucerne and Milan passes directly under the Pilatus and Rigi massifs, where tunnel portals are carved into sheer rock faces. For more on savoring the in-between, read how to find the best stops and hidden gems between cities.

Key metrics: distance 850 km, driving time 9-10 hours, toll cost ~€80 (Swiss vignette €40 extra). Best stops between Strasbourg and Siena include Colmar, Basel, Lucerne, Bellinzona, and Florence. How long to drive without stops? About 9 hours. Is it worth driving? Absolutely, for the Alpine panorama alone.

Natural Landscapes & Attractions

The route crosses three distinct biomes: the Alsatian vineyards (Vosges foothills), the Swiss Alps (Lucerne to Bellinzona), and the Tuscan hills (Chianti region).

• Must-see Alpine panorama: drive the A2 between Amsteg and Airolo – the valley floor rises from 500m to 2100m with waterfalls and granite peaks.
• Chianti hills: after Florence, take SS222 (Chiantigiana) through Greve and Castellina for olive groves and cypress-lined roads.

UNESCO World Heritage Sites

Three UNESCO sites lie directly on or within 20 km of the route.

• Strasbourg: Grande Île, Notre-Dame Cathedral (world heritage since 1988).
• Lucerne: the old town and Chapel Bridge (part of the medieval city center, listed).
• Florence: historic center (1982) – detour 10 minutes to see Piazza del Duomo.
• Siena: historic center (1995) – Piazza del Campo and Palazzo Pubblico.

Infrastructure Safety & Road Quality

All highways are well-maintained, but the Gotthard tunnel has no emergency shoulders – drive carefully. The A1 through Florence has heavy traffic and narrow lanes.

• Rest area frequency: every 20 km in France and Italy; every 30 km in Switzerland.
• Lighting: all tunnels are lit; Swiss tunnels have SOS stations every 500 m.
