Sustained climb but doable on gravel with wide tires. The descent on gravel would be no fun, always on the brakes. Be careful on the ridge at the col de Sucheyre, the stones are very aggressive, I tore the sidewall of my tire.

The Queen's Staircase is carved into the volcanic rock. A superb view of the surrounding mountains awaits you at the top of the 215 steps. The magnificent Royal Ladders circuit takes you to discover the Devil's Bridge as well as the Queen's Ladder and the King's Ladder.

Shakes way too much for gravel. Big stones, few rolling parts, it's a shame because it is indeed beautiful.

This walk starts very hard and certainly does not make it easy. Very beautiful on the other hand.

This magnificent stone bridge overlooks the Ardèche River at the foot of the village of Thueyts, 45 minutes from Vallon Pont d'Arc. 17 m high, it is an emblematic place of the Ardèche to discover. According to legend, the bridge was built under the inspiration of the devil, for the destruction of the souls of the young people of the village, who wanted to cross to the other side to hide their guilty loves, slipped into the abyss. "And on days when the river's current swells, we sometimes think we hear their desperate cries mixed with the rumbling of the water"

Source containing iron ore. Very hidden. Look carefully at the lowest point on the side path on the left. A very small pipe is the source. You can't hold a water bottle under it, just a small mug.

Coarse gravel, sharp rocks, exposed to the weather. Great distant views, a must.
