Source Bleue (Châteauvieux-les-Fossés) walks

Set off to discover two small valleys of contrasting light and shade. Then, as the landscape becomes wilder, you will come to the Source Bleue and, nestled in the greenery, the Tuffière, resembling the mouth of a giant forest creature, ready to devour you, ending at the Cascade du Raffenot at the bottom of a typical valley of the Loue.
