Hi, two possible ways:
1) All the route by train: around 3 hrs by the best connections, one train change in Grosseto
look at "51G-R" table
Either way you do this you'll need to get moving pretty early in the morning.
If your ship pulls out at 5 PM the all-aboard is probably 4 PM, or possibly earlier, you need to confirm the time with your cruise line. You need to allow a minimum of 30 minutes to get from the train station at Civitavecchia to the ship before they close for arriving passengers, so if your all-aboard is 4 PM your train to Civitavecchia must arrive by 3:30. This allows you enough time to walk the one mile to the free port shuttle that will take you to check-in.
The last train connection that gets you there in time departs Siena at 8:10 AM.
If you're traveling on a Sunday everything changes, these are Monday-Saturday schedules.Edited: 5:00 pm, February 20, 2018
Thank you so much, appreciated, sounds like we will not be able to dilly dally
Maxine, DID YOU MAKE IT??? If so, were you/did you feel rushed?
We are thinking of doing the same in a few weeks. Thanks for your reply!
Hi there we did make it. We actually stayed overnight in Civitavecchia before we went on our cruise which gave us plenty of time to get to the cruise ship.
We caught a bus (Flexibus) from Siena to Rome (it was 2hrs late in arriving in Siena), then got a train from Rome to Civitavecchia, there is always a conductor or someone on the platform to tell you the correct platform no. If you are going on a cruise it is best to get the free shuttle from the cruise port area in Civitavecchia to your ship as there is two sides to the port and a very long walk and if you get on the wrong side...you will see the tent sites set up for each cruise boat, they run a very good service.
Good luck and enjoy your trip.Edited: 9:28 pm, August 29, 2018
