How long is the road D265 to Col du Trible?
The road to the summit is called D265. It is 8.2 km (5.1 miles) long, running east-west from Le Chambon de Bavas to Saint-Cierge-la-Serre. Although fully paved, the asphalt is in poor condition with significant surface irregularities. The road is narrow: a single-track lane where passing oncoming vehicles is impossible for medium-sized cars in most segments. The route features 10 sharp hairpin turns and steep sections with a maximum gradient reaching 8.0%.
How challenging is the road to Col du Trible?
The main risks on the D265 are the lack of passing pockets and the presence of low stone walls along the road edge. These stone barriers provide minimal safety and further restrict the usable width of the pavement. Drivers must reverse maneuvers on steep inclines, as meeting oncoming traffic often requires one vehicle to backtrack considerable distances to the nearest wide point. The visibility is limited by dense roadside vegetation and the winding nature of the limestone terrain, requiring constant use of the horn on blind corners.
Is the road to Col du Trible open in winter?
While the pass is at a relatively low elevation of 540m, the road is prone to black ice during winter months due to its shaded northern exposure and proximity to the Rhône Valley humidity. There are no services, fuel, or passing lanes between Le Chambon de Bavas and Saint-Cierge-la-Serre. The D265 is strictly not recommended for long vehicles, trailers, or inexperienced drivers. During autumn, the road is frequently covered in wet leaves and debris, significantly reducing tire traction on the 8% steep ramps.
