The Leonardo Express by ECYM
After your flight lands at Leonardo da Vinci Airport, Rome's main airport in Fiumicino, it is just a short train trip into the city. All it takes is the time to claim your luggage and then the Leonardo Express whisks you off to Rome's Termini Station in only 31 minutes.
The ride is comfortable and cabin is spacious. And the frequency of the train is every 30 mins. Convenient!
Each trip is 9.50 euro.
