Long route, from Bau Acca to Truzzulla (T-421)

The trail starts from the village of Allai (OR) and climbs to a charming panoramic spot which also features a fire lookout tower that strategically covers a large area of the Grighine during the summer. 
 

Together with the shorter T-422 route (with which it shares the start and end points) this trail can form a ring route starting and ending in the village.

Monte Grighine Municipal mountain hut

Monte Grighine, bordering the municipalities of Ruinas, Villaurbana, Siamanna, Siapiccia and Fordongianus, reaches an altitude of 674 m a.s.l. with a beautiful all-round view of the Giare tablelands, the Gulf of Oristano and the Montiferru and Gennargentu massifs.

Near the summit stands the municipal mountain hut, available subject to booking and for a fee where hikers can prepare and eat meals, as it is equipped with gas cookers, tables and chairs. There is also a fireplace which however cannot be used in the summer because of the danger of wildfires.

The summit of Monte Grighine and the mountain hut can be easily reached by travelling 5 km along a blacktop municipal road that starts at the pass of provincial road 33 (Allai-Fordongianus), 3 km after the village.
