I am planning a trip to Italy the first week of May. I am taking the train from Rome to Chiusi than catching a bus to Montepulciano. Is there a bus that goes from Montepulciano to Volterra, or do I have to take the train to somewhere (I read that Cecina is the closest train station to Volterra) and then bus to Volterra? Is there an English website for trains and also buses around Italy? Thanks!
