Park at the Verrerie (glassmakers), slightly further down the D978. Coming from Autun, it's on your right.
(S/E) From the park, with your back to the houses, turn left onto the D978. Cross the road, take the footpath which starts at the end of the safety rail, arrive at a carriage road, after the small bridge.
Go right up the course of the Canche, past the power station to the penstock.
(2) After the penstock, ford the river and follow the Canche along its right bank, (a path laden with obstacles, fallen trees, small climbs, slippery fords...). At the top of the gorge, on the other side to your left, you'll see a riverside path.
(3) Cross the Canche and join the path. Follow it to the right and join the road (D179). Go past the dam and follow the road for about 1500m. Miss a path to the right and soon reach another fork in the road.
(4) Don't follow the GR®°13 on your left, but the unmarked track on your right.
(5) After just over 300m, take a large track to the left and follow it back to the forest road. Leave the 1st track on your right and the tracks on your left.
(6) Back on the gravelled forest road, follow it to the left, ignoring all other junctions. When you reach the D978, cross it.
Turn left towards Château-Chinon.
At the first crossroads, don't take the road on your right but the one opposite (D388), follow it through the woods and take the GR® on your right.
(8) Follow it straight ahead, missing a large track on the left, until you come to a road on the right (GR®) as far as the next crossroads.
(9) After 400m, turn left onto a track (GR®). When you reach the houses, follow the road to the right, which will take you to the cemetery.
(10) After the cemetery, turn right again, following this road for about 600m.
(11) Take a large track on your left, descending into the fields.
(12) At Les Guillaumes, fork right, then left. Cross the D978 and follow it to the left for 100m, then turn right onto the Canche gorges road.
(13) Before the wood, take a track on your right, then immediately left (leaving the GR®). Return to the road, cross it and continue along the track opposite. Leave the first large track on your left, and when you come to a large perpendicular track, turn right. The path ends here on a steep, rounded slope, take the right-hand part and descend it, you'll arrive behind the power station.
(2) Cross the river Canche and turn left onto the path you took on the outward journey to reach your vehicle (S/E).
