Great road with some tarmac irregularities at the first kms but finishes just great. Many corners particularly inside old and narrow stone bridges.
Beware not to wake up the customary dog sleeping on the side of the road in some locations.
Enjoy the views either from the river on your left, the mountain on your right or some centenarian stone villages that stand proud on top of slopes and terrain reliefs.
Also important: the food's great! :)
