Heritage wise: the granary-tower of the Viala-du-Pas-de-Jaux. Landscape wise: the sensational cirque of St-Paul-des-Fonts. Two unique sites that make this crossing of the causse an exceptional hike.

Built in the time of the Hospitaller knights, the granary-tower of Viala-du-Pas-de-Jaux is the starting point of this loop inside a sumptuous agropastoral landscape. Formed by the karst erosion, the cirque of St-Paul-des-Fonts (village with a museum dedicated to the botanist Hippolyte Coste) offers you a breathtaking sight.

3 points of interest

  • Agropastoralism

    The lavogne (cobbled watering place)of Font Rome

    This lavogne (cobbled watering place) of Font Rome, built in 1910 near tank wells is was first situated on a waterproof clay background. Then, it was built of stones all around and cemented. So this type offers the advantage of forming a passage that resists the trampling of sheep, and the gentle slope of the surrounding area limits the risk of slipping and falling of the animals. It is supplied by rainwater.

  • Panorama

    Cirque of St-Paul-des-Fonts

    The cirque of St-Paul-des-Fonts is a semi-circular natural cirque formed by karst erosion.

  • Flora

    Botanical Museum Hippolyte Coste

    Established on the ground floor of the presbytery adjoining the church of Saint-Paul-des-Fonts, the botanical space is dedicated to the life and work of the canon Hippolyte Coste who shared his life between the duties of his ministry and his passion for botany.
    This rouergate of modest peasant origins, which has been nicknamed "le curé des fleurs" (the priest of the flowers), knew how to rise in the yard of the greatest botanists by realizing in particular the remarkable and masterful «Flore descriptive et illustrée de la France, de la Corse et des contrées limitrophes» (1901 – 1906) which constitutes its masterpiece, known and still recognized today at the European scale.
    With this museum Saint-Paul-des-Fonts becomes an unmissable destination for all those who wish to learn by discovering the botanical wealth of the Larzac and Aveyron.
    Open from april to septembre. Free entrance.
