Spending about a week in Rome late September, but looking for at least 2 day trips out to the country: the Sabine hills and/or Frascati/Marino/Rocca di Papa. We'll not have a car, and seek an itinerary based on Trenitalia and/or autobus (and we're open to combining the 2). Sabina in general appeals more (Fara in Sabina, for one) and many of its towns are served on the Firenze-Roma regionale line. Frascati and its neighbors seem to be more accessible. For country air, small, quiet walkable towns, good non-fancy eating--suggestions/recommendations on directions, towns, and specific destinations welcome. Have searched CH boards and not found much on Sabina, but will keep looking. Not much interested in the coast, though. Might also consider Viterbo or Orvieto.Thanks in advance.
