Livorno is in Tuscany.
Livorno is on the Tyrrhenian sea in Italy. It is the third-largest port on the western coast.
Pisa airport (code: PSA) Galileo Galilei.
Main train station is Livorno Centrale. Take bus number 1 to go to town center and then to the port in about 20 minutes.
Many cruise ships stop here for at least a full day to allow guests to tour Florence and/or Pisa. Guests not taking cruise ship arranged tours can take a shuttle (supplied by the port) to the the downtown area. It offers a decent shopping experience, but not compared to Florence. A further 10-20 minute walk (or another bus ride) gets you to a train station. There you can take frequent departures for either Pisa or Florence. Many experts advise seeing Florence or Pisa on a one-day port visit by cruise ship. Though some tours claim to cover both, you'll get no more than a rushed look at a few icons...and if you're too early or late for any, it may well be closed.
If hoping for maximum time in Florence...
Bus number 1 is a shuttle from train station to the port and vice-versa. Ticket for one hour of travel is 1,00 Euros, daily ticket is 3,20 Euros. For self-reliant cruise passengers, this is part of the most economical way to reach trains to Pisa and Florence.
"Ponce alla livornese" is optimal to finish a meal (warm drink with coffee and rum).
Livorno is a good starting point and base for a tour of Tuscany. You can reach Pisa in half an hour, Lucca and Florence in somewhat over an hour. (See note under "Get in" "By Boat" above). In a well-organized day you can tour from a hotel in Livorno you might sample Chianti-side, Monteriggioni, San Gimignano, Siena and Volterra and be back for dinner. However, return before by expected time for a cruise ship departure could be quite problematic.
