How to drive the D135 balcony road through Gorges de l'Escharis?
The Gorges de l'Escharis is a deep limestone canyon located in the Drôme department of southeastern France. The road through the gorge, the D135, is a technical high-exposure route that ranks among the specialized balcony roads in France. Carved by the Roanne River, the drive requires high situational awareness due to its narrow roadbed and vertical rock walls.

Where is the Gorges de l'Escharis?
The canyon is located in the southeastern part of France, within the Auvergne-Rhône-Alpes region. Logistically, the D135 road follows the deep incision made by the Roanne River. The most technical sector of the drive spans 22.4 km (13.91 miles), running north-south from Espenel to Saint-Nazaire-le-Désert. This corridor serves as a critical but narrow link through the rugged Drôme mountains.
How challenging is the D135 through the Gorges de l'Escharis?
Technically, the road through the Gorges de l'Escharis is fully paved but presents significant challenges for modern vehicle widths. The roadbed is exceptionally narrow in several sections, featuring overhanging rock formations and tight turns with limited visibility. Logistically, the 22.4 km transit can be unnerving due to the lack of safety barriers in the most exposed "balcony" stretches. Drivers must be prepared for reversing maneuvers in the event of encountering oncoming traffic, as passing room is strictly limited in the gorge's interior.
What are the driving logistics in the Roanne River Valley?
The D135 is a sensitive logistical zone. While the scenery is dominated by turquoise water and narrow rock corridors, the technical focus remains on rockfall risks and surface integrity. During summer, vehicle density increases, making the narrowest parts of the Gorges de l'Escharis a high-concentration driving area. Safety protocols mandate a slow speed to manage the sharp bends and to account for the variable road width that characterizes this 22.4 km alpine transit.
When is the best time to drive the Gorges de l'Escharis?
Technically, the road is open year-round, but logistics change with the seasons. In summer, the Roanne River flow is reduced, but traffic peaks, complicating the 22.4 km drive. During winter or periods of heavy rain, the risk of rock debris on the asphalt is a primary concern. Technically, managing the D135 requires constant monitoring of the vehicle's position relative to the canyon wall, especially in the Saint-Nazaire-le-Désert sector where the roadbed is most constricted. Checking local weather alerts for the Drôme department is a necessity before attempting the full transit.
