Ciao - We are driving from Florence to Siena on October 12. We would like to take SR 222 towards Siena. Looking at the route, it seems to disappear past Castellina. What is the best way to use SR222 to Siena - and if we take this route, how long of a drive is it? Are there wine shops/vineyards for tastings, etc., along the way, any restaurants to recommend?
