Siena to Weimar: The Ultimate Road Trip Guide

The route from Siena to Weimar traces the ancient Via Francigena in reverse, crossing the Apennines and the Alps before descending into the Thuringian Basin. A little-known fact: the E45 highway near Bologna was built atop a Roman road, the Via Aemilia, and still follows its straight-as-an-arrow course for 260 kilometers.

This drive is a journey from the cypress-studded hills of Tuscany to the beech forests of Thuringia, spanning 1,100 kilometers and roughly 12 hours of pure driving time. Yet the best stops Siena to Weimar lie off the autobahn, in valleys where time seems suspended.
