A magnificent and demanding circuit to discover the Cévennes valleys and the famous terraces where the Cévennes sweet onion is grown.

Take the D999 towards Ganges, for around 6 km, as far as Le Rey, where you turn onto the D329 towards l'Arboux, then Costubague, Mandagout, St André de Majencoules, before rejoining the D986 and rejoining the D999 at Pont d'Hérault, where you head back towards Ganges.

At the junction with the road to Sumène (D20), don't be taken by surprise and change gear before turning, as it climbs to Cap de Coste before descending to Sumène, which you cross to continue along the meandering river to St Martial, then the Col de la Tribale. From here it's downhill to Notre-Dame-de-la Rouvière, then up again to Ardaillès, and after Le Gasquet cross the D986 to the Taleyrac valley.

In spring, the terraced fields of Cévennes sweet onions can be seen on both sides of the road as far as Taleyrac (D323). The winding road climbs steeply (up to 11%) to the Col des vieilles (782m), the highest point on this route, before descending to Le Vigan via Mandagout and the Col des Mourèzes.
