Bibulca Way (in Italian:Via Bibulca) was an old road dating back to the 11th century that used to link up Modena with Lucca and it was part of a much bigger network of roads. It starts where the Dragone River flows into the Dolo River in the La Piana locality (44°22′44.15″N 10°37′11.22″E / 44.3789306°N 10.6197833°E) and finishes at San Pellegrino in Alpe (44°11′30.55″N 10°28′55.39″E / 44.1918194°N 10.4820528°E), a hamlet (currently a frazione of the commune of Castiglione di Garfagnana) located on the ridge that separates the Tuscan from the Emilian Apennines. It was also called the Imperial Way due to its high toll that had to be paid in order to use it and that it could host a cart drawn by two oxen one beside the other, a luxury for the time. It has a length of 30 kilometers, starting from a height of 360 metres and arriving at a height of 1,529 metres. Now it is used as an amateur trekking path that runs alongside the Strada provinciale 32MO road and in certain stretches shares the same route.
