The port of Civitavecchia is very responsive and attentive to the needs of tourists arriving or departing from the port of Rome. Unfortunately, the service internally located at the port, is not yet activated so the best luggage storage solutions are outside the harbor.
The most practical and quick solutions to store your luggage, whether you arrive with a cruise or a ferry, are two: Luggage Storage at Civitavecchia Train Station, and Luggage Storage next to Varco Fortezza
