Train from Rome to Montisi
#2
I would think you could get to Torrie di Siena on one side and San Giovanni dasso on the other side. Taking a train from Rome the Torrie a would involve a change in Chili's Chianti another. I don't know about the San Giovanni connections. Have you looked at bus connections from Chiusi? How do you plan to get the rest of the Way? These small stations won't have taxis.
