Hi,

Fiumicino airport is about 30km from Rome centre, that’s nothing worth to see there… But 10 hours is a lot of time. I would take a train from Fiumicino to Center Rome (Termini Station). It’s cheap (around EUR 10) and takes 30 min…From Termini it’s easy to go to any touristic place in Rome…just choose one that you would like to see…and that’s it. Maybe the best would be to go to the Colosseo…
Have fun!!!

Thank you! I did as you suggested. It was wonderful. We shopped, had a gelato, saw the Colosseo and Trevi fountain, and then had a wonderful lunch. It was fantastic. I just enjoyed walking through the city. Thanks! We were there in July.
