After Terrazzu, you have to proceed towards Pani Loriga; if you want to visit the archaeological site, you need to cross once again the SP 293 two times to visit the site and come back. When crossing, pay attention to vehicular traffic on the provincial road.

Before arriving in Su Benatzu and just before Is Zuddas, you have to take a stretch of the SP 70 road; watch out for vehicular traffic.

This stage will lead you to barite quarries and several archaeological sites (Domus de janas of Su Cungiau de Tuttui, Nuraghi Moddizzi, Murrecci and Corongius Longus).

Upon arriving in Masainas, just before reaching the memorial stone, you have to cross the southern outskirts of the village while passing through Via Roma, which is none other than the urban route of the SS 195; therefore make sure to pay attention when crossing and passing along the streets of the village.
