Clue de Saint Auban is a spectacular gorge which links St Auban and Brianconnet (France) and has the Esteron River flowing through it. It is situated in Provence-Alpes-Cote d'Azur and belongs to the Alpes Maritimes.It’s one of the French balcony roads.
The D2211 snakes its way through the clue on a ledge and passes a chapel cut out in the rock where a service is held every September. The narrow and winding D-2211 is a roller-coaster through forests and mountains to finally climb up to the clue of St. Auban. St. Auban is one of the deepest, steepest and most spectacular clues in Provence. For two kilometers, the narrow one-lane road contours up the sheer ravine wall with a roof of rock overhead much of the way. It runs as a single track road along the mountainside for some distance with nowhere to pass another vehicle. Here one says a prayer that nobody is coming towards you until the road widens some kilometres further.
This road is one of the most famous balcony roads in the country. A balcony road is a hair-raising lane cut into the sides of sheer cliffs. It’s a kind of road not for those who fear heights. There is little room for error on these roads. Drive with care as this is a mountain road with hairpin curves and narrow unlit tunnels. When you take this road as picturesque as it is narrow, with its many suprising meanders, drive carefully, and above all don't miss the parking spaces that have been provided. To reach the summit of the Clue de Saint Auban, starting from Pont de St. Pierre, the ascent is 2,5 km long, with a gain of 116 meters and an average percentage of 4,6 %.

Do not travel this road in severe weather conditions. Avalanches, heavy snowfalls and landslides can occur anytime. A quick glance at the map at its sheer drops and serpentine twists and turns, confirms that this is no hype. With just a low concrete barrier between you and the steep mountain drop, it's best not to look down. Drive with care as this is a mountain road with hairpin curves and dangerous dropoffs. It’s definitely not for anyone suffering from vertigo or a fear of landslides.
