Firenzuola is best reached by car. From Florence, the route climbs through the Mugello and over Apennine roads that are scenic but slow. In winter, check conditions before committing to the higher passes.
Bus connections exist from Mugello towns, but they are limited and not ideal for sightseeing. If you want to visit Badia di Moscheta, Passo del Giogo, or the Futa cemetery on the same day, drive.
