To the mills

From the Lac-des-Rouges-Truites, in an open landscape shaped by agricultural activity, you will also discover that the industrial hand of man has done its work in a discreet way.
Shady or sunny, the paths are well suited to an introduction to mountain biking, and highlight the facets of the Grandvallier heritage: peat bog, old mill, tramway, cheese factory, etc.

From LE BUGNON, take the tarmac road down to the village of Les Thévenins, towards La Gare (green MTB signposting no. 67).
Carefully cross the D437, and continue straight ahead on a tarmac road that climbs to Le Crêt.
Take the stony track on the left that descends towards Le Puits, crossing a forest and pastures. Continue straight on the forest track which descends (be careful in wet weather) to reach the Moulin d'Hylarion.
It is possible to discover the Lemme marshes and the river's re-streaming from the Chatelet lookout, in a 1.2 km round trip following the road to the right, yellow markings. Turn left and climb the small tarmac road that runs alongside the Lemme. Go past La Maréchette, join the D 437 road, then turn right, LA HALTE DES MARTINS.
Carefully cross the road to take a stony path, the old tramway, which enters the forest and leads to Sous le Goulet. Follow this track straight ahead, which joins a tarmac road.
Follow this road to the right up to the Quatre Chemins crossroads and down to your starting point, LE BUGNON.
