Siena to Montepulciano: Ultimate Road Trip Guide

The SS2 via Cassia, originally a Roman road, connects Siena to Montepulciano over 70 kilometers of rolling hills. This route passes through the heart of the Val d'Orcia, a UNESCO World Heritage landscape. The driving time is about 1 hour without stops, but expect 2-3 hours with exploration.

Historically, the Via Cassia was a key artery for pilgrims and traders. Today, it offers a journey through vineyards, cypress groves, and medieval hill towns. The road surface is generally good, but some stretches are narrow and winding.

When considering how long to drive Siena to Montepulciano, plan for 70 minutes of pure driving. However, is it worth driving Siena to Montepulciano? Absolutely, because the journey itself is the attraction. For things to do between Siena and Montepulciano, see the table below.
