Basalt flow from the Strombolian volcano of Gravenne Thueyts. It reaches locally more than 50 m thick and 80 m high, so it is one of the largest of the Young Volcanoes of Ardèche and one of the highest in Europe.
This is visible from the Devil's Bridge and also along the "Devil's Bridge, King's Ladder" hiking trail.
All year round.
