The Tirso is the longest river in Sardinia. It rises as Riu de su Campo north of Bitti, in the province of Nuoro on the east side of the island, flows through the Lago Omodeo reservoir and flows into Oristano on the west side of the island. In the middle reaches it is spanned by the Ponte Ezzu, an old Roman bridge, near Illorai. It is 150 km long and is only navigable in the last few kilometers. The fertile plain north of Oristano through which it flows is called the Tirso plain.

Vedetta Truzzulla along the dirt road all uphill with sections with significant gradients of up to 18/20% starting from Siamanna on the asphalt provincial road to Allai. I recommend not doing it on hot days as there are few shaded areas.

The rural sanctuaries, typical of the Ghilarza countryside, have very ancient origins, and often preserve the remains of villages that have disappeared or been abandoned for centuries. There are also numerous pre-Nuragic and Nuragic remains in the area.

It was once the Forum Traiani, the most important Roman city in the island's hinterland, founded in the late Republic and becoming a marketplace between the inland communities and the Romanized population of the Gulf of Oristano under Emperor Trajan. Today Fordongianus is a small town of less than a thousand inhabitants in the Barigadu area, a renowned wellness center thanks to a thermal facility that uses saline and thermoactive water springs that flow at 56 degrees all year round and have beneficial effects on the body. A feature known to the Romans: the city is situated on the left bank of the fertile and lush valley of the Tirso, home to the warm and healing Aquae Ypsitanae, Roman baths from the 1st century AD, now an archaeological site. Two facilities can be visited, one retains a rectangular porticoed swimming pool, originally with a barrel vault, the other includes the changing room. The floor was in mosaic (you will see traces of it) and the ceiling in blue glass paste. The supply was ensured by a network of canals and a system of wells and cisterns. The importance of the thermal baths is confirmed by two statues of the god Bes, deity of health cults, and by a sacred space dedicated to the nymphs.

The Tirso is one of the largest rivers in Sardinia. Even in summer it still carries water. Here it flows idyllically under the bridge made of reddish trachyte blocks. A short path in the river valley takes visitors to the center of Fordongianus.

On the slopes of Lake Omodeo. Built on a Roman construction, probably from the 7th century. He sees the first muristene in 1657. The mountain landscapes and Lake Omodeo are stunning, as are the mosaics at the entrance to the church. The gates are always open, and the village can be visited even if uninhabited except for the period in which the novena is celebrated. In the main street, behind the church, you can find a drinking water fountain to top up.
