Col de Lachau
Col de Lachau is a mountain pass at an elevation of 1.332m (4,370ft) above the sea level, located in the Drôme department in southeastern France.
The road to the summit, located within the Vercors Natural Regional Park, is called D76 (Combe Laval Road). It’s asphalted but pretty narrow and steep, with some sections up to 9.1%. This road is one of the most famous balcony roads in France. A balcony road is a hair-raising lane cut into the sides of sheer cliffs.
