The Gola dell'Infernaccio, or 'Gorge of Hell', was carved by the Tenna River and features narrow passages and underground aquifers.
The mountain range acts as a significant watershed divide between the Adriatic and Tyrrhenian slopes.
Parco Nazionale dei Monti Sibillini spans 70,000 hectares across the Umbria and Marche regions of the central Apennines. The landscape is characterized by limestone peaks reaching over 2,400 meters, including Mount Vettore, the highest point in the range. It protects diverse ecosystems, including the glacial Lake Pilato, known for its unique crustacean species. The park contains historical mountain villages like Castelluccio, famous for its high-altitude lentil production. Seismic activity in 2016 caused significant structural damage to infrastructure within the park, necessitating ongoing trail and road accessibility checks. Trails connect various geological features, such as the Gola dell'Infernaccio gorge and the Grotta della Sibilla. The protected area serves as a habitat for wolves, golden eagles, and the rare Apennine chamois.
