Jaujac stands in the Ardèche section of the Monts d’Ardèche Regional Natural Park, where the Lignon river cuts through a landscape of volcanic rock. Insee counted 1,199 municipal residents in 2023 across the whole commune, at a density of 49.4 people per square kilometre. This is the administrative population, not just the central village. Jaujac is known for the Coupe, a Strombolian volcano with a north-open crater, and for the basalt flow that follows the valley. The Park’s geosite account traces the flow for about 3.5 kilometres and explains how the Lignon eroded it to expose columns of basalt. Here geology is part of the everyday map: river, stone, streets and footpaths meet within a small area.
A village around a public square
The municipal history describes a star-shaped settlement around the tree-planted Champ de Mars, with its fountain, parapet and role as a place for markets, gatherings and festivities. The nearby Chastelas quarter preserves the memory of an earlier castle; municipal history says the noble family of Jaujac lived there, and the regional walking description identifies remains on the slope above the river. Old records cited by the town use several forms of the name: Vallis de Gauga in 1255, Valles de Jajat in 1275, Gaugac in 1464 and Sancti Boneti Gaudaici in 1516. Those spellings document a changing written record; the sources consulted do not establish one simple modern etymology.
A history visible in the rebuilt centre
Jaujac’s municipal account says many older houses were removed during the second half of the nineteenth century. A more sudden break came on 5 November 1963, when a Royal Air Force aircraft carrying out a NATO mission crashed into houses bordering the Champ de Mars. The municipality’s 2023 commemoration records five victims and the unveiling of a memorial plaque near the Rue de la Poste; its historical page says twelve houses were later demolished and the new street and rebuilt façades changed the centre’s appearance. A walk around the square therefore brings together an older civic layout and a documented twentieth-century reconstruction, rather than one uninterrupted architectural period.
Work, services and volcanic paths
Today’s local directory lists a bakery, pharmacy, cafés, other shops, and the Sources & Volcans visitor office. The regional Park’s Maison du Parc is based at Château de Rochemure. Insee counted 258 jobs located in the commune in 2023; at the end of 2024 it recorded 34 employer establishments, 61.8 percent in trade, transport and varied services. These are dated measures of jobs and establishments, not a complete statement of household livelihoods. Shop and visitor-centre schedules vary, so confirm them before travelling. A municipal bulletin notes that the Turbine area on the Lignon is unsupervised; it should not be mistaken for a staffed swimming pool.
The main “Coupe de Jaujac et sa coulée” loop links the old streets, basalt riverbank, Rochemure estate and the interpretive climb through chestnut and pine. The Sources & Volcans route card lists 7.4 kilometres, three hours and +220/-220 metres; the regional tourism sheet for the same route lists 7.5 kilometres and +254/-218 metres. Because the published elevation figures differ, use the current GPX rather than combining them. The route source advises good footwear for the volcanic ascent. For a shorter accessible outing, Sources & Volcans describes the 1.2-kilometre “Sentier qui pétille” at Rochemure with audio, sign-language and easy-read interpretation; an all-terrain chair is available only on request, so confirm its availability. A separate 5.2-kilometre, moderate loop around the volcano starts in neighbouring Saint-Cirgues-de-Prades. Check river conditions, trail access and seasonal restrictions before setting off.
