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 is part of the homonymous protected natural area and extends for 0.287 km². The lake is fed by several tributaries, but the water flows slowly. This ensures that the temperature remains around 10-11 ° C all year round. Another feature is the transparency that allows the light to reach deep.

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.

"Fossa Maiura", a gigantic chasm already mentioned in ancient times ("description of Alvito et his Contato" Prudentio 1574) in the texts of historians and naturalists, for its geological and naturalistic peculiarities. The area still remains an example of integration between human activities (agricultural and pastoral) and natural balances, despite the relentless process of land abandonment, now revealing the testimony of an almost lost era. A few kilometers from the village of Alvito, in 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 that has a perimeter greater than a kilometer. Here the feeding waters of the Fibreno originate. Within the territory there is a spring from which sulphurous-ferruginous water flows. This very particular karst depression with the ancient districts of Cortignale and Cappudine, now abandoned, present themselves as real ghost towns. The two villages were completely depopulated already after the war, but within the walls of the stone houses you can still understand the customs and rules of the disappeared peasant civilization.
