This route runs through southeastern France through the departments of Drome and Ardèche.

The Drôme department is part of the Auvergne-Rhône-Alpes region. It is bordered by the departments of Ardèche, Isère, Hautes-Alpes, Alpes-de-Haute-Provence and Vaucluse. The canton of Valréas, called Enclave des papes until the French Revolution, belongs to the department of Vaucluse, but is completely surrounded by the department of Drôme.
The department takes its name from the river Drôme, a tributary of the Rhône, with a length of 110 km.

The Ardèche is part of the Auvergne-Rhône-Alpes region and is bordered by the departments of Drôme, Vaucluse, Gard, Lozère, Haute-Loire, Loire and Isère and the nearby Cévennes nature reserve and National Park.
The surface of Ardèche is 5,528.64 km², of which 172,000 hectares are covered with forest (31%). Most famous rivers are the Rhône, the Ardèche (river), the Chassezac and the Doux. There is a lot of natural beauty in Ardèche, such as the Gorges de l'Ardèche with the famous Pont d'Arc at Vallon-Pont-d'Arc. Here is also the regional nature park of the Monts d'Ardèche. There are also several caves, such as the Aven d'Orgnac, Grottes de Saint-Marcel and the cave Chauvet.

The route starts and ends at the village of Chalancon at Motovacances Chamauche, a great base for exploring this region. It goes straight up with a few hairpin bends to the Col de Chamauche. The long descent towards Valence starts from the Col, via winding roads and sharp bends. Towards Valence the mountains are getting lower and the roads busier. Just before Valence, a coffee stop is planned at an organic supermarket where they serve excellent coffee and sell delicious delicacies. We leave Valence on the right and continue towards the northern part of the Ardèche, The D633 is one of the most beautiful driving routes in the region, beautiful asphalt and an endless amount of curves take you to the highest part of the Ardèche. At 1404 meters you also reach the watershed between the Mediterranean and the Atlantic Ocean. From here you head towards the southern Ardèche. With sharp hairpin bends you drive to the river Ardèche.

The Ardèche is a river in France that has its source in the department of the same name at an altitude of about 1400 meters in the "Forêt de Mazan". At Pont-Saint-Esprit it flows into the Rhône at an altitude of 50 meters. Between Ruoms and Saint-Martin-d'Ardèche, it meanders through the Gorges de l'Ardèche, a canyon hundreds of meters deep with impressive rock formations. Most famous is the Pont d'Arc, an "arch bridge" created by nature over the river, near Vallon-Pont-d'Arc. In 1994, the Chauvet Cave was discovered in the rock formations of the valley, which contains the oldest petroglyphs known to date. The river crosses the departments of Lozère, Ardèche and Gard. The main tributaries are the Auzon, Ligne, Chassezac, Ibie and Beaume.

The lunch stop is planned in the town of Bayzan and you can refuel a village further. Via Aubenas the route continues towards Vallon Pont d'Darc, where the most beautiful part of the route in terms of nature begins. Here you follow the Gorges de l'Ardèche with beautiful viewpoints in many places. Take the time to stop regularly. It doesn't get any better in terms of appearance. At Pont Saint Esprit, the Ardèche flows into the Rhône. From here it is a bit of a struggle to cross the Rhône valley. This is not the most beautiful stretch of road at the moment, but from Nyons there is a few more kilometers of beautiful asphalt with beautiful keepers between the rocks. Don't forget to fill up your tank at Rémuzat for the next day. From here it is another 17 kilometers uphill to the end of this route where you can enjoy this beautiful route in the evening sun on the terrace.
