This trail takes you back to a time when the ruins of Tony's old mill bear witness to the austerity of yesteryear. The milling industry was of paramount importance to the rural world, which lived in virtual autarky. The route takes you through the wilderness of the Triouzoune gorges. You'll find typical country villages and enjoy superb views of the Monts d'Auvergne. Variant: +1.4km 2h30. Yellow markings.
