Denti della Vecchia, Mountain range in Lugano Prealps, Switzerland.

Denti della Vecchia is a mountain range in the Lugano Prealps with several limestone peaks, the highest reaching about 1,491 meters, forming a series of rocky spires. The formation sits near Lake Lugano and displays sharp ridges and steep flanks characteristic of the region.

Climbing here began in the early 1930s, when routes were protected with pitons and climbed in hemp ropes and climbing shoes. Shortly after World War II, André Roch, Emilio Comici and Riccardo Cassin trained on these walls. The Gruppo Scoiattoli dei Denti della Vecchia, founded in 1964, opened and documented many difficult routes.

The peaks earned their name, meaning Teeth of the Old Woman, from observers in the region who saw the jagged formation resemble worn dental structures. This name remains alive among hikers and climbers today and shapes how locals think about the place.

The marked trail from Capanna Pairolo to Alpe Bolla takes about two hours and is narrow and exposed in places. The climbing area is reached via Capanna Pairolo SAT, Capanna Baita del Luca and Baita Scoiattoli Cioascio; the last eastern crossing before the group lies at 1400 m near Bassa d'Ogé. Thanks to its southern position, climbing is possible almost all year.

The crags are the southernmost climbing area in Switzerland and are called the "Cross Mountains of Ticino". The marked trail from Capanna Pairolo to Alpe Bolla takes about two hours and is narrow and exposed in places. The best view of the tooth-shaped spires rising from the forest is from the opposite flank of Val Colla, near Bidogno.
