Dents de Lanfon, Mountain summit and climbing area near Lake Annecy, France

Dents de Lanfon is a mountain above Talloires on the east bank of Lac d'Annecy in Haute-Savoie. Its wooded, steep slopes end in a cliff of Urgonian limestone about 200 metres high, cut by erosion into three main points: the northern point, the central point at 1,828 metres and the southern point at 1,791 metres. The western face, seen from the lake, is the best known.

Early mountaineers began exploring the peaks in the late 1800s and established the first climbing routes. Over time, these paths have been refined and expanded to accommodate modern climbers.

The mountain draws climbers from across the region who gather to test their skills and learn from more experienced mountaineers. The rock faces serve as a meeting point for people dedicated to mastering alpine techniques.

The climbing routes are reached on foot from marked car parks below the mountain, with a steep ascent of about 75 minutes. Bring full climbing equipment and check local conditions and weather before setting off. The most familiar face, above Talloires and Menthon-Saint-Bernard, is the one seen from the west shore of Lac d'Annecy.

The mountain's three main points are the North Point, the Central Point at 1,828 m and the South Point at 1,791 m, while the English Wikipedia gives a summit of 1,824 m. The urgonian limestone cliff crowning the wooded slopes is about 200 m high. The massif stands above Talloires and Menthon-Saint-Bernard on the west side of Lac d'Annecy.
