The Vanil Noir ( Friborg Patois ) is the highest mountain peak in the Freiburg Pre-Alps in Switzerland . The border between the cantons of Friborg and Vaud runs over the mountain ridge . The name Vanil is an expression of the Friborg patois , means something like rock , rocky summit and originally goes back to the Gallic word vanno (slope, summit).
The Vanil Noir mountain range is bounded in the south by the Pays-d'Enhaut , in the west by the Haute-Gruyère , in the north by the Jaunbach valley and in the east by the high valley Gros Mont. From the highest point of the Vanil Noir, a grassy summit, three narrow and partly rocky mountain ridges run out: the first to the north or northeast, which leads to the peaks of Dent de Folliéran and Dent de Brenleire , the second to the east to Tour de Dorénaz ( ) and Dent des Bimis ( ) and the third to the southwest to the next almost equally high peaks Vanil de l'Ecri and Pointe de Paray (both ). The eastern side of the Vanil Noir is drained to the Saane via two streams of the Ruisseau des Ciernes Picat . In a cirque in the Vallon de Bounavaux on the western slope of the mountain there are two small mountain lakes; the valley is also drained to the Saane by a side stream of the Tâna .
From a geological point of view, the Vanil Noir area belongs to the Préalpes Romandes , a large-scale thrust mass of Penninic sediments, which are deposited as a cliff or cliff cover on Swiss sediments. The topography of the area is mainly determined by the rock material. Hard limestone ranges, which form the landscape features , alternate with marly layers that are much more eroded. The Vanil Noir belongs to the competent limestone of the Préalpes médianes plastiques . There are also typical karst phenomena in the region , for example cart fields , sinkholes and caves (including the Gouffre des Diablotins ).
The Vanil Noir area has been under protection since 1983 . Today's nature reserve covers an area of around 15 km² with the valleys of Bounavaux and Morteys. The Vallon des Morteys in particular is characterized by rare plant species ( alpine betony , pointed orchis , alpine flax , alpine shed head and mountain dragon head ). There are larger populations of ibex and chamois on Vanil Noir.
The Vanil Noir can be reached either via hiking routes through the Vallon de Bounavaux or through the Vallon des Morteys; The Vallée de Motélon bordering to the north can also be used as a starting point for ascents. The mountain hiking trail over the north ridge of the Vanil Noir has an exposed, difficult section, secured with wire ropes , with the gap in the rock of the Pas de Borière , which must be overcome.
