This undulating loop extends from the red lands of the Saint-Affrique area to the sumptuous medieval village of Brousse-le-Château. It is irrigated along the way by the Dourdou, Tarn and Len rivers. 

This long getaway has several demanding ascents, curves, and hairpin bends in store for you, but at each elevation and each turn, a new reward awaits you. The red sandstone village of Saint-Izaire, the fortress of Brousse and the three rivers with their meanders intersperse this very refreshing route situated in the heart of a landscape displaying a fantastic variety.

    Ardeliès 2 Carved Standing Stone

    This statue was subjected to several changes during prehistoric times as it displays both feminine and masculine attributes: one breast is visible and so is the masculine “object” which is a sort of dagger. This object is particularly detailed: ring and decorations with chevron ornaments that could represent the dagger sheath. The belt is represented by criss-crossed patterns and constitutes the only decoration of this kind, along with the grid pattern, which suggests the formation of the fingers of the hands. On the back, shoulder blades, belt and perhaps hair, represent the outline of a female figure.

    Ardeliès 1 Carved Standing Stone

    This statue displays several masculine features: the harness passing over the right shoulder and holding an “object” with a ring. The belt ornamented with a buckle, and the legs are clearly visible. The facial features are difficult to identify. On the back, the lines that extend arms or harness come to a stop on a central element with an unknown meaning. By analogy to the masculine objects, some suggest it may be a harness, but is it a warrior attribute, a body ornament or part of a garment? The issue remains unresolved.

    Ardeliès 6 Carved Standing Stone

    This statue must have represented a masculine figure as the trace of a harness is noticeable on the left side on the back. Arms and buckled belt are also still visible. The features of the face and back were achieved by picketing the rock. This technique was frequently used on the statues of the Ardaliès either for the engraving of figurative elements (Ardeliès 6) or to smooth the surface on which embossed elements emerged in relief (Ardeliès 9).

    Ardeliès 9 Carved Standing Stone

    This statue has undergone some changes, it displays breasts as feminine attributes together with a harness holding the”object” which are masculine features. Moreover, the ring of the “object” and one breast become confused. The belt chevron ornaments are meticulously crafted, and legs appear in relief on an evenly pitted surface. The back, shoulder blades and belt are depicted along with a central item. This could be an harness with a ring like those on the Ardeliès 1 statue, the Bancanel statue (Saint-Affrique) or the one of Saint-Jean-de-l'Hôpital (Montclar), all of these statues are not far away from one another.
