Really nice Toscanan landscape with easy curvy roads, enjoy!
I took this route out of Florence on SS67 and SS69 as a way into the next valley where Regello is, en route to Arezzo. It was a nice trek through the hills. Good roads, some nice curves. Not too much traffic. Good to get your feet wet if you´re renting a bike in Florence and finding the best way to get out of town (and heading east or southeast).
Curvas y mas curvas peraltadas! cuidado con los coches no respetan nada.
