It is said that the gorges near Ferrette were inhabited a long time ago. Dwarves lived there and lived in the hollows. These friendly creatures had eternal youth and beautiful childlike faces with shining eyes. Their small cave houses were decorated with all kinds of silver objects. To the left of the Grotto of Nains, where the Smurfs live, there is a crack in the rock, here you can climb up to the plateau and enjoy the beautiful view.
