I am hoping (Covid gods willing) to spend 10-12 weeks next summer traveling around north central Italy, Essentially, I'm thinking of a circuit roughly from Genoa, Pisa. Cinque Terre in the west, Tuscany, Florence, Lucca, Sienna, Orvieto, then east and north to Perugia, Ravenna, Verona and then perhaps a foray north toward Lake Como or Maggiore. I typically arrange house swaps in central-ish areas for stays of a week or more and take day trips from there. I have done similar trips in France, traveling by car from one stopping pointy to the next and have mixed feelings about repeating the experience in Italy. I don't mind the driving and enjoy the views as I meander from one place to another. And I love the freedom to make stops along the way and to easily drive to out of the way villages and points of interest from my lodging point. BUT, it can be tiring and, as I am a solo traveler, a bit isolating.
So, looking for advice on how much I'd gain...or lose...by relying on public transit. Thanks!
