To those travelling to Civitavecchia (Rome) and planning to do this port on your own with train, please understand that actual "Rome" is about an hour train ride away. The cruise ship docks at industrial port that requires free shuttle (about 5 minute) ride to take you out to the city of Civitavecchia. I think I saw someone attempt to walk but that would have been a very very bad idea as all the lanes are for trucks, industrial vehicles, and buses - the so called "walkway" is about a foot wide and seemed to end at several places. Also the buses go quickly without traffic stops so please don't attempt to walk out the dock! If anything just wait for the next shuttle, they come quite quickly.
The train station is about 10 minute walk (there are tons of instruction online - we just followed the throngs of people). We purchased two BIRG tickets from the ticket counter - I asked for "BIRG", the ticket attendant said "Roundtrip" - they were 9 euro each. Grabbed a seat then had merry journey to Rome. This train was considerably more well worn than the French train of the last stop, also lots of graffiti along the buildings - did not make for picturesque ride.
Got off at Roma Ostiense, switched over to the Metra B line to Coliseum. So it turns out that monuments in Rome are huge and close together. By close together I mean that you can see a whole row of monuments Circo Massimo, Palatine Hill, the Forum, and the Coliseum all together but it is a very long walk with little shade. I think the walk from metra stop to Coliseum was 20 minutes then the line already wrapped around the building with potential baking under the sun for 2-3 hours. We snapped some pictures and went along our way.
Our next Italy must go to stop was the Trevi Fountain - where we were told by the police officer at the Coliseum was 10 minutes away in a general direction. It was about 30 minute walk crossing giant streets with questionable traffic lights. The fountain was beautiful and everything we dreamed of and we threw in the coins for good measure.
Our next stop was Piazza Navonna which we were told by another polizia that it was 10 minutes away. We baked another 20 minutes and sat at a cafe to cool down. I think here was when I realized that either Italians walked really really fast or I should just double all the walking time I am quoted henceforth.
Vatican City (also the smallest country in the world) was our next destination. I was advised by the waiter that the walk from Piazza Navonna to the Vatican Museums would be roughly 1/2 hour - this was much closer to 40 minutes. The Vatican really was otherworldly experience, perhaps much better if there was not a sea of people moving you forward at every corridor. Definitely a site to see if you are visiting Rome. I was very impressed by the collection of paintings, sculptures, and details of every piece of ornament. It was literally miles of art to behold.
After leaving the Vatican, we were well exhausted and wanted to trek to St. Pietre Train station back to Civitavecchia but alas someone finally truthfully let us know the walk was about 50 minutes (he might have said 15) so we took the #64 bus from the front of the hospital.
Just when we thought our adventures in Rome came to an end - we met the cruise rush train ride. I came researched and prepared and read all about not being able to obtain seats so that you "might" need to stand the whole trip. I was not prepared to take running leap to jam myself into the doors with taller people than I, dripping sweat on me for 45 minutes due the very very minimal air conditioning. At least I was better off than the guy who had his face smashed up against the door window for 10 minutes.
After finally getting back to Civitavecchia, in an extraordinarily sacrilegious move, we stopped in the local McDonalds to enjoy AC and 0.80 euro ice cream cones (we had gelato earlier in the day). Shuffled back to the shuttle line, almost needed to crawl or partially dragged by my significant other to our stateroom. Shower. sleep.....
