The Fosso della Cornacchia ( the ditch of the carrion crow) is located along the rose colored flakes of Mount Nerone, a destination for canyoning lovers near Serravalle di Carda, not far from Apecchio. The trail during the winter allows admiring the waterfalls formed by the raging waters.

Located on Fiumicello, to the confluence with the ditch and near Valdara, is also a mill, now converted into a house.

Beyond the gorge you must be careful as the trail is marked by several hills and slopes. In some places you dive into the woods, until you reach the bed of the Trilla ditch, where is another beautiful gorge. Here canyoning is practiced. After crossing the ditch, you enter a large lawn crossed by a street that leads to the peak of Mount Nerone.
