Find Your Cruise
Exit the train station at Civitavecchia - turn right, follow the coast road, keeping the sea on your left. After 10 mins you will get to a small area where the complimentary shuttle busses are waiting on the left hand side which will run you to the ship. The port is huge, chaotic and it is not advisible to walk around it looking for a ship.
If you are wanting to go into rome , then dont go on a ships tour you can get the train and it costs 9 euro return, you can buy the tickets from a little newsagents inside the statio.
