Tarquinia is a town in Lazio, Italy. At first site it looks like a miniature version of San Gimignano with its medieval towers but the main reason for visiting is that it has fascinating Etruscan tombs with wall paintings (UNESCO World Heritage Site []), as well as a good museum on the Etruscans.
Trains run from Rome (mostly Roma Termini) and take about 1:30-2 hrs., cost about 7 Euro each way. There is a bus from the station terminating at the centre of the old town in Tarquinia. Within the old town there is a free bus to all the sights including the Netropolis. However, its also an easy walk through a peaceful mediaeval town.
Run to and from nearby cities.
By car from Rome, take the Autostrada that runs northwest along the coast in the direction of Civitavecchia. Tarquinia is not too far after the end of the Autostrada at Civitavecchia but take care as the road is a popular stretch for the police to operate speed traps and catch you for overtaking illegally.
From Civitavecchia: There is a direct bus that picks up at Piazza Vittorio, Civitavecchia. The bus company’s name is Cotral. It is a large blue bus marked Tarquinia and it drops off at Barriera S. Giusto, Tarquinia (near Tarquinia InfoPoint). The ride takes about 25 minutes.
There's a local bus to the necropolis.
