The route of about 4 km leaves from Greggio town center and, after a first asphalt stretch, entirely develops on dirt roads: the first lap is represented by "tombe del Sesia", the siphon with which channel Cavour passes under river Sesia, where you will also find a descriptive panel. The route continues along the riverbed, enters the Park and, finally, beyond the outlet of channel Cavour, it goes back to the departure point.
The route develops both within and outside the Park, is adequately marked, and easily accessible on foot or by bike (any kind of bike).
