If you are looking for a road that combines the adrenaline of driving with a primordial landscape, the Gorges des Gâts are a must-see stop in the south of the Vercors. This incredible canyon, about 10 kilometers long, carved into the limestone rock by the Gats stream, connects the valley of Châtillon-en-Diois to the Col de Grimone. The route winds along a narrow and winding road that hugs vertical rock faces, crossing stone bridges and short tunnels dug directly into the rock. The view is impressive: the grandeur of the cliffs contrasts with the green of the vegetation and the blue of the stream flowing at the bottom of the gorge.
