Val Pentemina is a small side valley of the upper Trebbia Valley, located in the municipality of Torriglia, in the heart of the Ligurian Apennines. It extends through chestnut and beech forests at the foot of Mount Prelà and takes its name from the Pentemina stream that flows through it. It is a quiet and sparsely populated valley, where time seems to have stood still: ancient stone villages like Pentema bear witness to the rural life of the past.
