Trail no. 13, labelled Uni'Vert Trail by the Fédération Française d'Athlétisme, 13.7km from Châtel-Montagne.
Starting from Châtel-Montagne and its 12th-century Romanesque church, this moderately demanding circuit takes you to the Puy du Roc, from where a superb panorama of the Auvergne mountains awaits you. During your run, you'll also pass the pretty Saint-Clément lake and dam.
