From Piazza al Serchio the path rises along the river to the Acqua Bianca (White Water) to reach the medieval villages of niches, and Castagnola Agliano, the latters overlooking the lake Gramolazzo.

On a hill near the lake stands the bulk of the Old Church, abandoned building eighteenth and only recently the subject of a recovery.

A Gorfigliano in the new church of San Bartolomeo is kept sacred, ancient, and a wooden statue depicting a medieval holy bishop.

The route continues along the stream by sending the Acqua Bianca (White Water) in the heart of the Apuan Alps in a mountain of great interest to the passage of Focolaccia, before falling back on the side of Massa.
An interesting digression on this journey is the path parallel to the glacial valley of Orto di Donna, to the mouth of Cardeto, towards the Valley Hotel, formerly the territory of the province of Massa.

The area is characterized by the extraction of marble with the creation of striking artificial fronts due to excavation and ravaneti, landfill of waste material.

As a result of intense mining activity and prolonged in time, the Apuan marble basins are characterized by huge volumes of debris waste of cultivation, the so-called "ravaneti", which are discharged along the slopes adjacent to areas of the quarry and that are now a typical element of the landscape of the Apuan Alps.
