Because Pisa itself is the central historic and transit hub located within the Tuscany region, traveling from Pisa to other Tuscan destinations (such as Florence, Lucca, Livorno, or Viareggio) is exceptionally easy via regional trains. To reach Florence, for instance, you simply board a frequent Trenitalia regional train from Pisa Central Station. The journey takes approximately one hour, runs multiple times every hour, and requires no advance booking, allowing travelers to purchase inexpensive tickets directly at station kiosks or via mobile transit apps before departure.
