Pisa to Florence -trains

If you go to the Trenitalia site and click on the 'language' button in the upper right corner, you'll get English as an option. Really, though, the trains go very frequently along that route, so you can just go to train station, buy your ticket, and you're off. EDIT: even on the English site, you need to look up cities by their Italian names; Florence is Firenze. It has several train stations, and you most likely want the main one, which is Santa Maria Novella.

alpha31zulu, you want to use Italy's national rail website, Trenitalia. It has an English version:

To explore schedule from Pisa to Florence, enter " Pisa Centrale" in the "From" box
Enter "Firenze S. M. Novella in the "To" box
Choose a desired date and time. To look at schedules coming back, just reverse the process.

Use the site only to explore train times: your journey will be on inexpensive regionale trains, and tickets can be purchased at the station the morning of your day trip(s). These tickets will need to be validated (time-stamped in little machines near the tracks) before you board the trains.

Another option is to take the Terravison bus from the Pisa airport to S.M. Novella station. We did this during a train strike, and the buses are clean, air conditioned and very comfortable:

Do be aware that some of the museums in Florence will be closed on Monday: Uffizi, Accademia, Palatine Gallery, and some others depending on what Monday of the month you'll be there.

I understand you are flying into Pisa, however, unless you have some business to do in Pisa, you won't need to stay in Pisa overnight at all. There is nothing to see in Pisa, except for one piazza with a bell tower that everybody wants to see because it's leaning on one side, otherwise nobody would even bother to go there. To see Pisa you need a couple of hours max, which you can do after you land before heading to Florence by train.

If you don't want to bother with Pisa at all, not even on the day of arrival, you can actually take a bus directly from the airport to Florence. The train won't save you any time because you need to take a shuttle to the station first.

You're from Florence, aren't you?

Pisa is wonderful.
The all Field of Miracles is a UNESCO World Heritage Site, and they did not put it on the list because of a leaning bell tower.

The Buffalmacco fresco in the Cemetery, now partly under restoration, is a priceless masterpiece of western art.

Ciao Dario,
Thank you so very much for your link.
It makes me want to go back to Pisa and dedicate a bit more time to it... I have a home in Florence ... Ha ha

Thank you so much everyone for generously sharing all your diverse ideas and experience, this forum is awesome!

If you stay in Firenze, you can easily daytrip to Pisa and Lucca in one day (have lunch or dinner in Lucca, not in Pisa near the tower).

I agree with Dario, there is a lot to Pisa - even just the Campo dei Miracoli - besides the bell tower, although Roberto is also right in that almost everyone goes to Pisa to see the tower and take a photo.
