This is a very easy walk that takes about an hour and a half to reach the Grotta della Madonna.
From Borca via Villanova, you can get there by taking forest road 460, which leads to the green plains of Tièra.
After the bridge, known as the bridge of the Madonna, there is a small path on the left, at the end of which you will see the cave dug out of the rock, built as a vow of thanks by the villagers for having escaped danger.
One winter, during the transport of wood from the woods with the "lioda" sledge, it overturned on the bridge and miraculously stopped on the precipice.
