The road to the summit is gravel. It’s an old military road, not for beginners. It’s very narrow and should be used by experienced drivers only. Along the road there are several military constructions and fortresses. The road is winding, in some places only wide enough for one vehicle, and in many places bordered by a drop of hundreds of meters (many hundreds of feet) unprotected by guardrails.
The road was built in 1830. After rain, sections of road can become decidedly hazardous when fast-flowing creek crossings and slippery mud can cause road closures. The track to the summit is impassable between September and June and includes several hairpin turns. It’s narrow and very steep, with sections up to 20 %. Near the summit sits the Ouvrage Pas du Roc, a lesser work (petit ouvrage) of the Maginot Line's Alpine extension, the Alpine Line.
