So here is how you can easily reach one of my favorite places just 12 miles from Rome: Ancient Ostia.
Ancient Ostia is the most undervalued archaeological site in Italy. In my opinion and for those who work with tourism, it is a hidden gem. It can be compared with the most known Pompei and is also easier to reach. It has beautiful mosaics, an outstanding theatre, and a gorgeous setting under the old pines away from the mass.
If you'd like to reach this extraordinary ancient city, you must take the metro (subway) line B to Pyramid. As you arrive, follow the signs to the Ostia train line, which is within the same building as the subway. As you leave the subway train platform, take the escalator and turn left, and it is just next to the ordinary subway line. The trains leave every 10 minutes so that is the maximum you will need to wait for the next train.
After 26 minutes and seven stops, get off at Ostia Antica. As you arrive at the station, the train will leave you on the platform on the opposite side of the station, so you will only need to take the underground passage to get to the exit. Don't try to use the bathroom because it is out of order from prehistoric times.
As you exit the small train station, you will see a bridge in front of you. Take the stairs, cross the bridge over Ostiense street, then walk straight in front of you for 5 minutes. You will find a gate, go through it, turn left and find the kiosk of the ticket area of the archaeological site. The bathrooms are next to the ticket area. They are working again after a coach hit them, injuring a poor tourist who was inside.
You will find a self-service and another toilet in the middle of the archaeological site, near the Museum and the bookstore.
