A biological environment of major European interest, this peat bog lies at an altitude of 900m in the communes of Meymac, St Merd-les-Oussines, Chavanac and St Sulpice-les-Bois. It occupies a huge 250ha depression, where numerous springs and streams merge to form the Vézère. Its size, unusual landscapes and the diversity of its flora and fauna make the Tourbière du Longeyroux one of the natural gems of the Plateau de Millevaches. Two paths allow visitors access to the peat bog. A booklet providing information on the two waymarked paths and the bog is available from Haute Corrèze Tourist Office in Meymac (1€). Guided tours from 2.30-4pm on Thursdays in July-August, departing from the tourist office in Meymac; all year round for groups by prior arrangement.
