You will notice the abundant presence of the endemic black arum plants while crossing the Campu de Coxinas.

The excursion also has a powerful cultural connection since it retraces some of the pages from Paese d’ombre (Town of Shadows) by Giuseppe Dessì, a native of Villacidro, offering intense emotions to those who have already read the novel.

The excursion leaves from the pineta del Carmine pine grove at 300 metres a.s.l. behind the residential area. Penetrating the dense pine grove, you will head towards the Parco di Castangias park at the old rifle-range at 333 metres a.s.l. The pine grove will accompany you to Genna Is Paboneddus, at 496 metres a.s.l. without any particular challenges. This pass will offer the first suggestive view of the Coxinas hollow and there is a fun road linking to path 108 as you approach the bottom of the valley. Once you have surpassed the dam on the rio Coxinas, you will wade into stream and continue on into the heart of the valley at Campu de Coxinas to then climb up to Genn’e Prunai, at 725 metres a.s.l. and from here continue climbing all the way up to the rocky peak of Monte Margiani, at 859 metres a.s.l., which Dessì calls Monte Volpe (Mount Volpe) in his famous novel Paese d’Ombre (Town of Shadows).
