Lucca & Pisa + Siena

Those are regional trains
No need to purchase in advance

There is a bus from Lucca that drops you right near Field of Miracles
Train is a 20-30 min walk unless you take it to Pisa Rossore

Not familiar with bus from Lucca to Siena but if it drops you up in town I’d take bus rather than train
Train requires 1 or 2 changes and drops you bottom of the hill

For Field of Miracles you could purchase online to avoid any wait in ticket line as long as you are sure of your dates

Hello jodycsr,

The trains to Siena come from Florence or Pisa but either way you'll end up with 2 changes. It looks like on the current Saturday schedule all the Lucca > Florence trains change in Pisa anyway so there's no reason to not take this one:
Lucca > Pisa Centrale > Empoli > Siena (~2.5 hours)
There are essentially 2 every hour all day and it costs ~14e so just pick the one you want.

I'm not familiar with the buses from Lucca but nothing seems to promising anything faster than the 2.5 hours of the train trip and most seem to stop at the Siena train station anyway. Some people prefer the bus from Florence over the train because it drops you in the center rather than at the bus station, but in these cases the endpoint seems to be the same.

Hope that helps, all those towns are great, have a good trip,

You are going to have a fantastic time, great choices of places to visit! I took a train to Lucca and Pisa from Cinque Terre and it went super easy. Have fun :-)

We took the bus from Lucca to Pisa. It dropped us off, and later picked us up, at the Field of Miracles. Very convenient. I believe it was VaiBus #E3, but you can check here: https://lucca.cttnord.it/Linee_e_Orari/linee-extraurbane/L/573. We didn't buy tickets in advance for any part of the Field of Miracles, but we were there in mid-April so not very crowded, except for the Cathedral.

Buon Viaggio!
