Start at the church square in Torcé-Viviers-en-Charnie.
(S/E) Walk round the back of the church, turn right onto the road towards Neuvillette-en-Charnie (D9) and follow it for about a hundred metres. Turn right into Rue de l’Avenir and continue along a path that skirts the lake.
(1) Cross the D9 with care, then the D161 (Route de Parennes), until you reach a track.
(2) Turn right and follow a wide track round Bouillé Castle.
As you reach the departmental road via a small open area, take in the view of the gate (monumental entrance) and, on the other side of the road, the Tour du Trésor. Turn left to walk alongside the D161.
(3) Look for a small path on the right that crosses the plateau. At the junction between La Tellerie and Le Petit Fourneau, carry straight on. Cross the D9 with care and continue climbing towards the first patches of woodland at Bel-Air.
(4) Head down the D146 for a good 200 metres and turn left onto the Bel-Air forest track, which leads to the Haute-Croix-Mallard crossroads, skirting a lake.
(5) Turn left to climb the forest track towards the Grande-Charnie ridge, a high barrier of Armorican sandstone quarried until the end of the 19th century to supply many of Paris’s cobblestones.
(6) At the junction, head down to the right towards Les Tuileries, follow the road to the left and turn right about a hundred metres further on.
(7) Turn right onto a lovely path towards La Croix-Mallard, where you’ll rejoin the tarmac road. Then turn left.
(8) Follow the D146 to the left to head back down to the village of Torcé-Viviers-en-Charnie (S/E).
