I will be Assisi in August and was hoping to do a "day trip" to Siena. In checking the sena.it bus schedule, it looks like there is only one bus that arrives in Siena at 13:40 ...and later departs back to Assisi at 17:00. This only leaves a few hours, so it does not appear to be a good option. I will not have a car.
Does anyone have a suggestion as to a better way to travel between Assisi / Siena for a day trip???
