After a few days of ancient ruins and shopping until you drop you may want to escape the city and head for the beach or the hills. Both choices are close and easy.
Rome is less than 20 miles from the sea. Rome is also blessed with a sunny climate that makes a seaside lunch an almost year-round affair. the resort town of Ostia is easily reached by a swift light rail train that leaves regularly from the Piramide metro stop. La Vecchia Pineta is all old fashioned Dolce Vita glamour.
The Umbrian hill town of Orvieto is less than an hour from the main train station. With an early start you can visit the town’s magnificent cathedral with it’s frescoes painted by Luca Signorelli, feast on local specialties like pasta topped a sauce of wild boar and crisp Orvieto Classico wine, shop for hand painted ceramics on the via del Duomo and be back in Rome in time for dinner.
