The Cévennes are a partly mountainous hillcountry in south-central France, a part of the Massif Central. The mountain ridge runs southwest to northeast, and is bordered by the Grands Causses, the Montagne Noire, in the southwest, and by the Monts du Vivarais to the northeast. As it is a geographic region, its borders are different to the political borders. It covers parts of the départements of Gard, Lozère, Ardèche, and Haute-Loire. This means it belongs to three different régions: Languedoc-Roussillon, Rhône-Alpes, and Provence-Alpes-Côte d'Azur (PACA).
