To reach Tarquinia from abroad, we suggest to fly to Roma-Fiumicino airport. You will then be able to reach Traquinia by frequent regional train service changing in Roma-Trastevere (note: you do NOT have to use the express "Leonardo" train to Roma Termini, as this does not stop in Trastevere), see schedule on the website. Tarquinia train station is NOT  at walking distance from the city center; you will need a bus or taxi. Bus schedule will be posted here in spring; moreover the organizers and the Hotel will be happy to arrange transportation for you if required.


Beside the interest of Tarquinia per se - seaside, medieval town and etruscan remains - and the possibility to easily reach Rome by train, the area has many interesting nearby (less than 1 hour drive) places which may be of interest to accompanying persons. Many of these easily reached also by public transportation (see Trenitalia and Cotral web sites), albeit having a car would be an advantage.

Among these we mention (see e.g. Wikipedia for details):
