This natural wonder is the Tufière de Saint-Ciergues. It is a small tufa formation created by the deposition of limestone on moss, forming a series of small waterfalls. Tuff is a porous stone which gave its name to the site. You can enjoy the view of the tuff and the surrounding forest, but be careful not to step on it, as it is very fragile and needs to be preserved.
