The Gorges du Guiers Mort is a canyon formed by the Guiers Mort river in the Isère department in southeastern France. It’s one of the French balcony roads.
The gorges are traversed by the D520B road, also known as Route du Désert. The gorges are located on the route between La Diat and Saint-Laurent-du-Pont, two municipalities in the Isère department in south-eastern France. This amazing road is carved into the mountainside in France. It’s a road to die for (or die on, if you're not careful!). This cliff road is asphalted. It's normal for your palms to sweat looking at those photos, imagine what it must have been like before the barriers.
Located within the Chartreuse Natural Regional Park, 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. There are not many roads like this in Europe, if you can handle the height and the prospect of a very long freefall this road absolutely has to be on the list of any road connoisseur.
