(2) Walk past Chazier Farm and continue along the track heading north-east.
Go through the gates, closing them behind you, and carry on until you reach a concrete track.
Follow this track for about 200 metres downhill to reach a junction with a footpath.
(3) Turn right onto this path and you’ll soon come to the Discovery Trail. Walk alongside the pond and continue along the path until you reach the Mont Saint-Christophe Forest Road.
(4) Turn right onto it and walk to the right-angled junction with a forest track.
(5) Keep going straight ahead on the forest track to reach the radio masts. Take a moment here to enjoy the magnificent view from this viewpoint.

At the top of the track, turn left and follow the edge of the woodland to the Labry barn. Walk past the barn.

(8) Turn sharply 90° to the right onto the forest track, which is suitable for vehicles. You will then begin a gentle descent. At the Y-junction, keep to the right, following the signs for Moirans-en-Montagne.
Further on, you’ll come to the signpost for Tongea.
