The south side of Gennargentu Mountains has highly spectacular areas for the people who drive along the few roads crossing it, particularly the SS 198.
In order to reach the declivities of Mount Tonneri and Mount Perda Liana, if you arrive from the Sardinian inlands, it is necessary to start from the village of Seui and to go towards the state forest of Montarbu, a land characterized by the presence of many calcareous towers (tacchi) and of closely-planted trees like holm-oaks, ashes, hollies, wild pear-trees, with a scattered Mediterranean scrub. Various lanes lead into the forest where you can easily sight wild-boars, mouflons, foxes, weasels, buzzards. Continuing on the road towards Flumendosa Lake (Lago Alto del Flumendosa), immediately after the Genna ‘e Medau pass, Mount Tonneri rises in front of you.
At the following pass, S’Arcu ‘e su Pirastu Trottu, you will park the car and take a path that skirts the natural step of a calcareous rock: from that point you will enjoy a unique view, extending from Mount Gennargentu to the Flumendosa valley.
After a short drive, you will meet the base of Mount Perda Liana, one of the most famous 'tacchi' of Ogliastra; its top dominates a beautiful area teeming with woods mingled with rocks and green pastures.
if you leave from the coast of Ogliastra, you have to go to Lanusei and then to Villagrande Strisaili where you will find the signal showing the right direction.
