From Florence, we did a quick day trip to Rome. Our train departs SM Novella at 9:38 and arrives at Roma Termini, Rome at 11:10. That’s a 1 hour 32 minutes ride for a distance of 276 km with the train cruising at a maximum speed of 250 km/h on some stretches and 120 km/h on curved track. It will take 3+ hours if you drive. As always, the train is smooth and comfortable.
Once you’re at Roma Termini, you can choose taxis or buses for you to explore Rome. The metro also converge into Roma Termini and is a level down. The metro ticket cost €1.50 and can be used on city buses and trams as well. You can also buy the ticket at the newstand at the metro level.
Our itinerary in Rome is to visit the Colosseum, Trevi Fountain, Spanish Steps and the grounds of the Vatican. All these has to be completed fairly quickly as our return train to Florence is at 16:50. Although hectic, we did manage all of it with time for lunch and tea before returning.
