Wonderful little-used road that meanders up the mountain in tight serpentines. Great road surface, so that this road is also ideal for racing cyclists. However, they have to turn around at the top, because the connection between Piscia and Vacca is a bumpy dirt road, for which you should already have a trekking bike or MTB. In Vacca the road is paved again, and sometimes a real snake sunbathes on the warm pavement ;-)
