Every day, ferries leave the Sardinian port of Olbia for Civitavecchia, which is a handy arrival point for those visiting Rome. All ferries from Olbia to Civitavecchia are operated by Tirrenia, which reaches the mainland in eight hours, so it's a relatively time-consuming journey. There's a single crossing every day, which usually departs at around 10:30 p.m., and travels overnight to reach Civitavecchia around breakfast time. Travelers can take as many cars and bikes on board as they desire.
Travelers should be aware that there is only one crossing between Olbia and Civitavecchia every day, so there won't be many services to choose from. The only ferry of the day leaves in late evening, and takes eight hours to reach the mainland, docking in Civitavecchia shortly before breakfast. The ferry itself is a large vessel, capable of carrying 2,908 passengers and 850 vehicles. Passengers can choose to reserve deck seats, or book their own cabins for an extra fee.
Olbia's passenger port offers simple dining options and places to purchase travel essentials. All Tirrenia ferries leave from the Stazione Marittima Isola Bianca, which can be found on a peninsular just outside the city center. Both the number 5 and 9 buses serve the port, and there are on-site parking facilties if required. At the other end of the voyage, the port of Civitavecchia is around 1.6km from the town's railway station. Taxis are probably the best way to make the transfer. However, passengers can also head to nearby Largo della Pace and catch either the CSP or PortLink buses. Both serve the station, where passengers can easily transfer to Rome-bound trains.
