I need to go from Florence to Siena on the evening of Sept 24th, and I understand that it is better to take the bus than the train since the train station in Siena is some distance from the city. I also understand that the bus station in Florence is very close to the SMN train station. I do not know how to find the bus schedule however. Can anyone help?

If you decide to take the train, there is an elevator, buses, or taxis to get you inside the walls.
