Würzburg to Sion: Ultimate Road Trip Guide

The direct route from Würzburg to Sion spans roughly 520 kilometers, taking you through Germany, Switzerland, and a sliver of Austria. You’ll spend about 5–6 hours behind the wheel if you stick to highways: A3 south to the A1, then the A2 across Switzerland to Lausanne, and finally the A9 along the Rhône valley to Sion. A specific fact: Würzburg’s Residenz (a UNESCO site) was built in 1720 by Balthasar Neumann, while Sion’s Valère Basilica dates to the 12th century—two bookends of a journey through centuries of European culture.
