The route leaves the Sieve valley to climb the hills separating the Mugello from the plain around Florence. The route is of medium difficulty, not so much because of the overall length of the climbs which, moreover, leave ample room for recovery, - the difference in height is 844 meters - but because of the particular stretch of the Salaiole climb. Its ramps, although short, reach slopes close to 20% and therefore require considerable effort, as well as the availability of very light gear ratios (39/28-30 or compact equivalents) if you do not want to risk putting your foot on the ground.
If our condition does not allow us to tackle such rugged climbs, it is possible to travel the entire length of provincial road 302 from Borgo San Lorenzo to Vetta Le Croci, a much easier though less spectacular road. For climbers, on the other hand, we recommend climbing, from Bivigliano, to the Convent of Montesenario: three hard kilometers but rewarding with spectacular views of the Mugello.
