The river Vandra (in dialect La Vandura) is one of the longest rivers in the province of Isernia (about 30 km), it flows on mainly clayey and impermeable soils, so it has a torrential character. Starting from Villa San Michele, a small village, now abandoned, in the municipality of Vastogirardi, and then descending along the river bed, one is fascinated by the beauty of the landscape and the extraordinary clarity and transparency of the water.

The crypt and cathedral of Gravina in Puglia bear witness to the artistic and religious tradition of the town, which was the birthplace of Pope Benedict XIII.
