We recommend this efficient bus route finder map (below) for Pisa, Italy, because pdf network maps for Pisa may be out-of-date. Public transport routes can change from year to year and the local bus company has, at the time of writing, not produced one since 2017. The pdf transport network map is still fairly accurate, but if you want to be sure, see the simple instructions in the red box.
There’s a similar route finder on the Italian bus company’s website.
Pdf timetables can also be downloaded from there. Look for Linee e orari (Lines and times) and then Linee urbane Pisa (Pisa city lines). The timetable for each line is under the column heading of Orari.
Think twice before taking the bus. Pisa is not a big city, and the main tourist sites are just a pleasant 20-minute walk from the station, with interesting streets, churches, shops and markets on the way. It’s flat all the way too. Get a map from the tourist info at the station first or use the map on your phone.
For the major sites, consider booking ahead to avoid long lines at the ticket office:
