Nice 2.5 km climb from Le Martinet. At the top, the pass is the confluence of several forest tracks that allow you to explore the surrounding mountains, one of which, the Chemin de Trélis, allows you to reach Rochessadoule.

Despite its current state, which is essentially in ruins, the castle (or more accurately, Castrum) of Allègre remains impressive and bears witness to nearly 10 centuries of history. It features towers and stately homes, a double rampart, a chapel, and a village. Located at an altitude of 275 meters, overlooking the middle valley of the Cèze, the entire site covers one and a half hectares and offers a sublime panorama of Mont Bouquet and the entire Cévennes (orientation table). Very close to the D37, the tour is best done on foot after leaving your bike in the parking lot.

Ideal for gravel and touring bikes. Very safe, far from the sometimes heavy traffic during peak season. On my mountain bike, I found this cycle highway rather monotonous and boring. It's an ideal connecting road to the trails.

The Via Ardeche railway cycle path is a nice idea in itself, but unfortunately, the perfect surface (asphalt) is only present in the tunnel sections. The rest is rough concrete, gravel, and even worse.
