The Pilat possesses an astonishing fauna and flora which is a delight to those who take time to contemplate the sites of the Crêts du Pilat, the peat bogs and moors of Chaussître, the Ondenon valley and the Combes du Pilat Rhodanien, which are now classified as Natura 2000 to ensure the safeguard of this wilderness which is as beautiful as it is fragile.
