Taxi from Livorno to Livorno (city)
If you don't like to walk or take a shuttle bus, then a taxi is a good alternative to go to the city center or train station. The center is located a few kilometers from the port. The journey takes 15-20 minutes and count on approximately € 20 per taxi (4 persons one way).
Keep in mind that most drivers prefer to sell you a day trip and are not eager for a short drive to downtown.
