The route first goes past Montichiello, one of the many very picturesque villages in this area. Then the route descends to the valley of the Orcia, which is on the UNESCO World Heritage list.
You will first visit Bagno Vignoni, another small very picturesque village (or rather a hamlet), known for its hot springs: the central square of the hamlet is a hot spring fed by a volcanic layer deep underground!
After that, the route heads towards the mountain massif of Monte Amiata and the roads become quiet.
The real climb starts in Seggiano, where you take the northwestern side that partly goes through a narrow road through a dark beech forest. The western side from Castel del Piano is more well-known, but whether it can compare to the northwestern side via Seggiano is unknown.

Monte Amiata is heavily forested with beech, birch, and chestnut trees. So you hardly have any views unless the leaves are falling in autumn.
Above 1250 meters in elevation, the road surface gets a bit worse. You do not cycle via the shortest route to the top, but follow the ring road under the summit (to avoid as much as possible going back and forth on the same road in the upper part). The summit lies, after 21 kilometers of climbing, at just under 1700 meters in height. Then it’s downhill, sometimes with worse road surfaces in the upper part (!). Via the old mining town of Abbadia San Salvatore, the route heads towards the valley of the Orcia. Before you enter the valley, you will encounter the road from Le Conie to Contignano, offering you many beautiful views. In the last 3 km, you climb via a gravel road to the endpoint of the route over the SP88, which is also used by regular traffic.

The roads on this route are generally quiet to fairly quiet in terms of traffic.
