A few kilometers from the town of Alvito, among the mountains bordering Abruzzo, there is the so-called Fossa Maiura (815 m), a karst depression that almost forms a natural amphitheater: it is a gigantic sinkhole about 100 meters deep and about 3 km in circumference, in the shape of an inverted truncated cone with a perimeter of more than a kilometer. This is where the waters that feed the Fibreno originate.

The lake of Posta Fibreno or della Posta, a nature reserve, is one of the most beautiful, characteristic and unspoiled natural oases in all of central Italy. Included in the green Valle di Comino, this huge source of pure water, coming from the slopes of the nearby mountains of the Abruzzo National Park, gives life to the icy and clear Fibreno river. Singular peculiarities of the lake are the floating island and the ancient boat with a flat bottom. The small trout called "Carpione del Fibreno" (endemic) and the rare macrostigma trout find their natural habitat here. The lake has always been frequented by scuba divers or free diving and by birdwatching enthusiasts.

In the territory of Casalvieri for a matter of meters from the border with Arpino. The picnic area is well equipped (unfortunately the usual uncivilized people leave garbage everywhere) but I think it is more a place for the spirit than for food. Breathtaking 360 ° panorama.

Terrific look! According to Komoot, there is no way here. However, following the trails as far as Komoot is concerned, they are also well marked until just before the summit. Just before the Punto Mazza you should keep your eyes open to see all the markings, which then follow only difficult to follow paths. All in all, the ascent is good to do.
