The Roma metro system has two lines: the red A-line and the blue B-line. As a visitor, you’ll find yourself on the A-line the most. It goes from Termini past the Trevi Fountain, Spanish Steps, Piazza del Popolo, and most importantly, the Vatican.

The B-line will get you from Termini Station to the Colosseum and Circus Maximus. These are the most popular stops for visitors using the metro to get to Rome’s top attractions.

You can’t get to Trastevere by metro, but you can get close to Testaccio by getting off at Piramide. Both Trastevere and Testaccio are known for their lively nightlife and great food. Your hotel and most Airbnbs will have a metro map that you can keep handy.
