It is an itinerary of less than 50 Km., which follows the highway n. 126, the Sardinian Western highway. In this area, which constitutes the richest and most varied mining region in the whole of Italy, one encounters Fluminimaggiore, with the temple of Antas; the seaside area of Buggerru (Capo Pecora, the beach of Portixeddu and the dunes of St. Nicolò); Arbus, with the Costa Verde (Green Coast) and the Marina of Arbus. Taking various detours along mainly unmade roads, the itinerary allows us to visit a series of old industrial villages. Significant for their environmental, landscape anf architectural value, are those of St. Benedetto, Ingurtosu, one of the most important 19th century examples of mining settlements in the island, and that of Montevecchio, a half-abandoned village situated in the centre of a metalliferous complex, considered for years, one of the most productive and efficient among all Italian industrial centres.
