Roc Lancrenaz, Mountain summit in Haute-Savoie, France
Roc Lancrenaz is a limestone hogback that rises between the communities of Alex, Talloires-Montmin, and Thônes in the French Alps, reaching 1679 meters above sea level. The formation has a distinctive ridge shape that stands out in the landscape and offers wide views across the surrounding Bornes Massif.
For centuries, the mountain paths around this summit served as essential routes connecting villages across the Bornes Massif. These historic routes shaped how communities traded and traveled, and many of them remain as marked trails today.
The area around this summit has long served as a meeting point for people traveling between mountain villages in the Bornes range. The trails that wind through here still connect communities and draw hikers who come to experience this part of the Alps.
The main trail from Montmin covers about 9.6 km (6 mi) with roughly 840 meters (2750 ft) of elevation gain and is clearly marked on hiking maps. Wear sturdy boots and bring plenty of water, as the route includes steep sections that become slippery in wet weather.
The Pas de l'Aulp is an exposed rocky passage where metal chains are fixed into the rock face to help hikers navigate the steepest and most exposed sections safely. These anchored cables transform a challenging stretch into a manageable climb that stands out from typical alpine routes.
