I want to make a trip to Pisa next month with my parents. We will be there around 3 or 4 days. Our plan is staying in Pisa and doing short day trips to nearby towns, as we have already been to Pisa before. One day we wanted to go to Cinque Terre, another to Lucca (that is pretty close and with easy access by train).
Our doubt is if we can do a day trip to Siena, because I can't find a train or bus connection. In case it is too difficult (or too far), any suggestions on where to go on the last day? We've been to Firenze already, so we are rulling that one out.
Thanks in advance!
