Head to Frascati, one of the historic hill towns to the South East of Rome known as the Castelli Romani. This town has been a popular destination for centuries away from the hustle and bustle of the capital, and this is still true today. Famous worldwide for its white wine, Frascati is a relaxed hill town with a slower pace of life. Just 21km from Rome, Frascati is accessible by bus or train. Trains run from Roma Termini approximately every hour, take about 30 minutes, and cost around â¬2. Also in the Castelli is Castel Gandolfo, the summer residence of the Pope. The town overlooks Lake Albano, a popular weekend trip for Romans in the summer. Also accessible by bus and train but there are several interesting towns and villages in the Castelli so hiring a car for the day would be well-rewarded.
