Just before the town of Nasino, practically at the point where the road slopes steeper, in the "Mulino" area there is this beautiful arched bridge, in an excellent state of conservation... a good excuse to catch your breath before the climb!

Here you take the downhill path to the right. Too bad there is no maintenance, otherwise the hairpins in sequence would be spectacular. We have found a lot of digging, branches, stones and alas we did a good part of the descent on foot
