The Dents de Lanfon (Teeth of Lanfon) are a mountain in the Bornes Massif bordering Lake Annecy. There is a great view at the summit but the trail is quite difficult. I followed this itinerary.
Starting in Annecy-le-Vieux, I took my bike in the direction of Thônes, passing east of Mont Veyrier. I then turned at the road leading to Menthon-Saint-Bernard and went up to the hamlet of Villard-Dessus in the village of Alex. I parked my bike then followed the forest road to the Chalet and pastures of l’Aulp Riant Dessous. At the Chalet, I left the road (which continues towards the Lanfonnet) and started to walk in the direction of the Dents de Lanfon. The trail gets around the Dents on the north side then goes up: That part was very steep with unstable rocks. I arrived at a place near the north Dent with a view on the lake. I then took the path on the way to the middle Dent: There were a few passages where hands were needed. Finally, I arrived at the summit some time after. Unfortunately, there was a lot of fog so the view was limited. I took the same path on the way back. I then went back to Annecy by completing the loop around Mont Veyrier, going past the castle of Menthon-Saint-Bernard then following the road along the lake.
