Although taxis are available at the Civitavecchia’s port to take you to Rome, this is going to also be a very expensive choice. Consider that taxis are metered and charge base on distance, and Rome is 80 kilometers (50 miles) away, so your journey will cost between €125 to €150 or more. Consider this as the option of last resort if none of the others are available.
If money is not an object, then this can however be a stress-free way to get to and from Rome. You won’t have the hassle of waiting for public transport and can relax on the journey there and back. And if indeed budget is not a barrier to your transport choice, you could even treat yourself with a private limousine. This would provide an even comfier ride to Rome and back, although naturally is more expensive, with prices varying among operators.
Private shared transfer
A slightly more affordable alternative to taking a taxi is to sign up for a private shared transfer service. These shuttle buses usually take small groups of people to Rome for a flat rate per person, with prices dependent on which company you choose. Many of these transfer companies offer their services at the port, so you can step off your ship and choose among them. But it is usually helpful to book these transfers in advance because they can sell out, and having a booking guarantees your ride to Rome and back. Expect the cost to be lower than a taxi, although you’ll still be at the mercy of traffic which could make it a long journey.
