Departure from the Chantres/Saint-Cassin car park.
(S/E) At the end of the car park, take the small road on the right. After 200 metres, leave this road and take a path on the left that runs alongside private property. This path, marked in yellow, leads to a track at a place called "Sur la Rave".
(1) Continue right on the track. At the end of the next bend, take a path on the left just before two concrete blocks on either side of the track. Ignore the paths that branch off to the left (3 in total) and continue to a crossroads called "Chalet Lélia".
(2) Turn left onto a wide track towards "Col du Planet". After passing Chalet Lélia, follow a left-hand bend. After this bend, take a small path on the right. Cross a track and continue along the small path towards Corbeley/Col du Planet. Reach Col du Planet (1184m).
(3) At the pass, turn right towards "Corbeley" and descend towards a small meadow, ignoring the path that branches off to the right towards Granges du Planet.
(4) From the meadow, take the track on the right that heads north-west towards Le Corbeley to reach Plan du Bouc.
(5) At Plan du Bouc, turn right. Continue, ignoring a path on the left. At the fork, take the left path.
(6) At the fork, leave the main path and take the small path on the left marked with yellow signs. This path then climbs almost straight up the slope, following the yellow signs. When you reach the rock, walk along it on the right. You will reach the foot of the rock, where a vertical cable indicates the route to take. Climb the rock (the first ten metres are tricky). Reach the ridge and enjoy the view. Then continue towards the summit on a small path below the ridge.
At the end of the path is the summit. Continuing past the summit, a path below the ridge leads to the end of the massif where, approaching very carefully to the edge of the cliff, you can see the vertical rock face next to Corbeley.
(7) Return to the Col du Planet via the same path you took on the way up.
(3) At Col du Planet, leave the route you took on the way up.
You can also choose to take the same route you took on the way up to return to the car park.
If you opt for the circular, at Col du Planet, be careful, as part of this return route is very difficult to see (between (9) and (10)). The GPS function on your smartphone will be a valuable aid in staying on track. Continue straight ahead towards "Col du Mollard". The path descends to a stream.
(8) Cross the stream. Immediately turn left, then left again onto a path that descends.
(9) Turn right downhill (well before a stream) following the yellow markings. At this crossroads, hidden behind a tree, a sign indicates "Tour de la Drière" (you have to turn around to see this sign hanging on a tree when you are at the crossroads). The path will become less and less visible.
Follow the yellow markings, which become increasingly scarce. Cross the bed of a stream, which is usually dry, to reach a wide path. Take this path to the left to reach a track.
(10) Follow it to the right. Descend towards a stream and cross it. Turn left to follow it. At the "Y", take the left path which will follow the stream on the right, overlooking it. Cross a road and continue along the path opposite. At the fork, turn right then veer left and climb a short path to reach the road.
(11) Follow it to the right to reach the car park on the left (S/E).
