Monte Pulchiana is the largest granite monolith in Sardinia, situated on a highland in northern Gallura, at 550-673 m above sea level. It is an inselberg that originated from the breakdown of the rock via a process of hydrolysis. It has a characteristic round form, "panettone" (traditional Italian Christmas cake) and is partly covered in low, ground hugging brush; the rocky surface has a pinkish-yellow colour due to the process of oxidation.
Monte Pulchiana is included among the natural monuments of Sardinia and its characteristic form brings its surroundings to life, a scene of great charm and emotion. It is found, in fact, within a spectacular granite landscape, which has no comparison in the other areas of the island: tafons, tors, rocks in heaps, and a dome inselberg. The plant cover is characterised by brush and woods of cork oaks.
Another characteristic of Monte Pulchiana is the upland plain of Lu Pari, covered to a large extent by rockrose. Part of the land is for pasture and during the rainy months is also becomes marshy. Near this plain it is possible to see an open excavated road that was used to transport large blocs of granite extracted from a now disused quarry.
