Rome airport train rides are the most affordable transit option from FCO to Civitavecchia Port. However, they aren’t convenient, as they require a change of line. Still, they remain a value-for-money alternative for many travelers on a budget. Explicitly, the train options from Rome Airport to Cruise Port are:

The fast train runs from the airport train station, lying in front of T3 close to both terminals, to Roma Termini in the city center. It is equipped with luggage racks, charging outlets, and first-class seating, and operates every 15 minutes from 06:08 am to 11:23 pm. Leonardo Express needs only 32 minutes to get to Termini Station and costs 14€/15.40$. Children up to 4 years of age are out of charge, while each paying adult can travel with one kid aged 4-12 for free. Tickets are available online. In that case, they are already validated and must be used within 90 minutes of the set time. Alternatively, you can buy them from some retail stores, the airport ticket offices (from 06:45 am to 10:12 pm), or the automatic vendors. However, you’ll have to validate them before catching your train.

Once reaching Roma Termini, you’ll hop on the FrecciaBianca route to Civitavecchia.  Thus, the overall rail ride from Rome Airport to Civitavecchia Port will last around 96 minutes and cost about 30€/33$. Please note that the rail station in Civitavecchia is located almost 1.50km/1 mile from the Cruise Terminal. From that point, you’ll find free cruise shuttles to your exact terminal. Local buses also link Civitavecchia Station to Cruise Terminal, costing around 2€/2.20$.

No matter the chosen train line, you should opt for an early reservation. As a matter of fact, early bookings usually come with lower fares.

Instead of the fast Leonardo Express, you can take the somewhat slower yet also cheaper FL1 Train, running every 15 minutes from the airport train station from 05:57 am to 11:27 pm. On Sundays, it operates until 00:27 am while running on a 30-minute frequency. The regional train doesn’t have designated luggage space but costs only 8€/8.80$. Tickets are available online or through the ticket counters (open from 06:45 am to 10:12 pm) and the automatic vendors. Although all tickets have to get validated before hopping on the train, online tickets are already validated. Still, they have to be printed and shown at the turnstiles. Children younger than 4 don’t pay for their tickets, while one kid aged 4-12 per each paying adult travels for free as well.

The FL1 Train will get you to either Trastevere Station in about 27 minutes or Ostiense Station in 34 minutes. At Trastevere Station, you can take one of the regional trains heading to Civitavecchia every 20-40 minutes from 06:57 am to 10:57 pm. The total traveling time will be around 110 minutes, and the price for your transit from FCO to Civitavecchia Port will be 11€/12$. Alternatively, you can head to Ostiense Station and take the intercity trains to Civitavecchia. However, even though the duration of your journey will be about 90 minutes, intercity trains run 4-5 times a day and are more expensive. Therefore, you’ll have to pay 19.50€/21$ for your ride. In any case, after reaching Civitavecchia Train Station, you’ll have to use the local buses or walk to the Cruise Terminal, located almost 1.50 km/1 mile away.
