Trail no. 43, labelled Uni'Vert Trail by the Fédération Française d'Athlétisme, 43.6 km, starting from Saint-Nicolas-des-Biefs.
On this route for experienced runners, you'll explore much of the south-eastern Montagne Bourbonnaise and some of its most beautiful sites: the Assise state forest, the mysterious Pierres du Jour, the village of Lavoine facing the Rocher Saint-Vincent, and the lower slopes of the Verrerie plateau with its heather fields.
