This leg starts from the historic centre of San Piero a Sieve and follows CAI Bo-Fi signposting. After a little while, you have the option of taking a little detour to see the Medici Fortress of San Martino, as well as the Castello del Trebbio, breathtaking views, and a tabernacle from 1664.
Following the CAI 17 Bo-Fi Bivigliano directions, you will pass olive groves, medieval hilltowns and the distinctive landscapes of the Mugello. Carry on until you come to the main road for Florence, whereupon you turn left for Tagliaferro, eventually coming to the Abbey of Buonsolazzo.
After a break at the monastery of Monte Senario, you come to Olmo. The CAI path no. 2 continues climbing towards Poggio Pratone, which affords a stunning panorama over Florence. From Poggio Pratone you descend to Monte Fanna on a dirt track, at which point the route becomes asphalt again. You traverse the hamlet of Borgunto, and soon find yourself in the piazzas of Fiesole.
Here you can take the bus bound for Florence’s Piazza San Marco, and disembark instead in Piazza della Signoria. Or stay on your feet and take the CAI path no. 7, which climbs to Monte Ceceri and then drops into Coverciano.
