Initiatory walk between the stone trees
The cypress and palm trees follow gigantic cabbages and imaginary monsters. Immaculate candles stand before monumental organ buffets to give way to magical oases.

A vertical chimney 75 meters high and 3 meters in diameter rises from the vault of the room to the surface of the Causse Méjean in the form of a funnel and a mysterious well.
