You will cycle in the Campidano of Oristano, a generous territory irrigated by River Tirso and by Cabras pond, and on the way to the volcanic mountain masses of Montiferru and Monte Arci. Water is an essential element that gives life and provides well-being. It flows among the ancient channels of Fordongianus thermal baths of Roman origin, and it becomes a valuable resource to preserve inside the Santa Cristina well. Not only do the minerals enrich the local sources of water coming from the Park of San Leonardo di Siete Fuentes, but, following a millenary manufacturing process, they also become obsidian - a refined and strong volcanic glass known as “oro nero” that embellishes the jewels and protects the Sardinian population since the pre-Neolithic age. Aged in Contini's humid cellars, the local wine will pamper you after you've explored the slopes and coasts of this splendid central-western area of Sardinia.
