5 points of interest

  • Natural environment

    The Mont Aigoual forest

    “Aigoual, Forêt d’Exception”
    The French Forestry Office, which manages state forests, launched a programme in 2013 called “Aigoual, Forêt d’Exception” (Aigoual: An Exceptional Forest) with the aim of highlighting the massif’s natural and cultural heritage. The Forestry Office thus tries to foreground the different aspects of its multi-facetted management: production, protection and receiving visitors. One key aspect of this approach, which complements other initiatives by local actors, is to improve visitors’ experience in the forest.
  • Landscape

    Col du Suquet pass

    You are at the highest point of the hike. On the right bank of the Dourbie, the path crosses a sheer slope that is alternatively made up of zones of solid granite and other zones where it has decomposed due to weathering into coarse granitic sand. To the south, the views encompass the entire Lingas massif, a high wooded plateau overlooking, further south, the region around Le Vigan and the Languedocian plain.
  • History


    A former farm turned forester's house in 1880. In the early days of the Mont Aiguoal reforestation, forestry officers lived here year-round during their missions. Forestry workers working on the replanting were allowed to use the outbuildings. Later, only one official resided here. Since 1967, no official has permanently lived here. (B. Mathieu)

  • Water

    The Bonheur river

    The Bramabiau site is an example of a karst spring. Here, slightly east of Camprieu, the Bonheur River has dug into the Causse (limestone plateau) and disappears in a natural tunnel. It re-emerges into the open at the bottom of the Aven de Balset, but it twists to the south to disappear again below ground. The river meanders through more than 10 km of tunnels. Then, 700 horizontal meters from its sinkhole, it reappears as a spring! The rock walls of the narrow canyon magnify the sound of its waters and add to its rumbling some acoustic vibrations that are close to a gigantic roaring. This is no longer the tranquil Bonheur, it is the tumultuous Bramabiau.
  • History


    In the 19th century, the village streets were bustling year-round with a throng of artisans, labourers and shopkeepers, who lived in these modest mountain houses that were also suitable for livestock rearing. Camprieu had: two cobblers, six clog makers, two basket makers, one carpenter, two wheelwrights, two farriers, one miller, two stonemasons, one glassworks, one sawmill, one dairy, two grocer’s shops, a haberdashery and ironmonger’s and one shop for ladies’ “fashion and dresses”. There was also a cheese cellar that produced Roquefort until 1932, a hotel and an inn.
