Taking a taxi from Pisa International Airport to destinations within Pisa city center typically costs a fixed or metered rate ranging from €15 to €25, depending on luggage, night tariffs, and exact drop-off locations. However, if you mean traveling by taxi from Pisa Airport to other major parts of Tuscany (such as Florence, Lucca, or Siena), private taxi fares increase dramatically due to the long distance, often costing anywhere from €100 to €250+, making regional trains or pre-booked shared shuttles far more economical options.
