The route starts from Brisighella RA and arrives at Borgo Tossignano BO, through paths that climb the cliffs of the chalk vein, (vena del gesso). (Editors Note: the .gpx file shows an out-back).

"A spectacular silvery gray ridge"
"From the Sillaro valley to Brisighella, in the Lamone valley, the Romagna hills are furrowed by a spectacular silvery gray ridge well recognizable at first sight, which abruptly interrupts the gentle hill profiles giving a unique aspect to the landscape. The outcrop, which is the longest and most imposing chalky relief in Italy, extends for 25 km and has an average width of one and a half kilometers. The area is characterized by peculiar karst morphologies, which include sinkholes, blind valleys and numerous caves, among which many "abysses" stand out."
