The Forest of Montes, access to which is a few kilometres from Orgosolo, extends for 4,500 hectares on elevations around 1,000m high, from the first spurs of the Gennargentu massif, passing through the high valley of the Cedrino river and the Orgosolo Supramonte area, as far as the Rio Flumineddu river, on the eastern border. 1,000 hectares are occupied by an expanse of holm oaks, 20-25m tall: it is Sas Baddes, one of the most ancient and extensive holm oak forests in Europe, which coexists with maple trees, holly trees, strawberry trees, phillyrea and yew trees. In the undergrowth, there are peonies, the wild Gennargentu rose.
In the forest there are wonderful landscapes, among which the natural monument of Monte Novo San Giovanni that has aiguilles up to 70m high, where rare endemic flowers grow, some of which are unique.
There are numerous springs in this location: from the Funtana Bona, the Cedrino River starts its course. Here there are sheepfolds featuring pinnetos, shepherds' shelters made of stone with cone-shaped roofs made of branches. There are also various Nuragic ruins: the village of Sas Baddes, inside the holm oak forest, two Tombs of the Giants, near the valley of Sa Senepida, and, in the heart of the forest, the Nuraghe Mereu, built from white limestone rocks.
The dolina of Su Suercone is one of the natural monuments in the area.
