The variant of the Mercatorum Way that branches off at Dossena reaches the floor of the Brembo valley at San Giovanni Bianco, after having gone through San Gallo. The ancient route coincides partly with today’s roads. In the section along the Piazzo Valley, there is a lovely stretch of paved mule track, which ends at the recent housing developments in San Giovanni Bianco. The Ponte Vecchio bridge brings this section of the Mercatorum Way onto the same route of the Priula Way hiking itinerary. It is useful to remember that from San Giovanni Bianco to Cornello, the route of the Mercatorum Way follows the path of the Priula Way hiking path. In this case, we are referring to today’s current hiking routes and not the original historic route of the Priula Way, which follows the course of the state road 470.
