The Sangro river was born in the National Park of Abruzzo, Lazio and Molise at 1441 m asl under the Passo del Diavolo, Marsica territory, on the slopes of Mount Turchio. It flows into the Adriatic Sea near Torino di Sangro after about 122 km. Its waters bathe two regions (Abruzzo and Molise) and the territory of three provinces: L'Aquila, Isernia and Chieti. Initially it flows from north-west to south-east in narrow and deep gorges and in Villetta Barrea (AQ) it forms the artificial lake of Barrea. Immediately after the town of Alfedena, the watercourse crosses the plain of Castel di Sangro, receiving the waters of the Zittola river. In the stretch that goes from the town of Castel di Sangro, in Ponte della Maddalena, about 100 meters above the Iron Bridge, along the confluence with the river Zittola, there is the CONI Fly Fishing Gym and it is practiced "no kill" fishing for trout. The Sangro is certainly one of the most fishy rivers in Italy. During the summer its banks are a destination for many tourists and on the day of August the Masked Regatta takes place. Beyond Ateleta, in the stretch up to Quadri (Ch), the river marks the border between Abruzzo and Molise. Downstream, its waters give life to the artificial lake of Bomba and the reservoir of Serranella, which today is a controlled nature reserve of the Abruzzo region. Near the mouth, on the right bank, there is the Lecceta Regional Reserve of Torino di Sangro.
