Public transport is usually cheap and efficient and is probably the best way to visit Italian cities, since parking, petrol and motorway tolls are quite expensive in Italy.

Generally speaking, it is usually more expensive to buy a single ticket, so it is worth your while finding out about the cost of weekly or monthly tickets for transport in your town.

Be aware that bus tickets are not sold on board and need to be purchased beforehand, usually at tobacconist's and newsstands.

All tickets must be stamped before boarding trains and underground trains or on board buses.

Train:

Train ticket Milan - Rome 38.00 (Intercity train), 47.00 (Eurostar train) / one way
 

Bus:
All the major cities have extensive bus and tram networks but these can inevitably be slow during peak traffic hours when the towns become very congested.

 Metro:

The Rome metro system, simply called Metropolitana by Italians, runs approximately every 3-5 minutes, from 5:30am until 11.30pm every day (until 1:30am on Saturdays). Tickets can be purchased in newsstands, tabacchis, or vending machines.
