Park in the car park opposite the town hall in La Baume-Cornillane.
Yellow signposting
(S/E) With your back to the town hall, go to the signpost opposite the town hall, above the information board on the right. Follow this small tarmac road uphill towards the feudal village. After 100m, the tarmac gives way to dirt and then comes to two houses.
Turn right and then immediately left to follow the path between the two houses. The trail enters a wood, ignore a path on the left and continue climbing until you reach a flat area. Turn right and then right again to climb up to the ruins of the 12th-century castle, which offers beautiful views of the plain.
(1) Descend and return to the ridge where you will find an information panel about the centre of Pangaea. Turn left onto a path that runs alongside a line of rocks. After 120 metres, ignore a path that descends to the left and follow the path that curves to the right, passing between the rocks. You will reach the Réservoir signpost.
(2) Leave the path on the left, which will be the return route, and continue right towards Serre Perrier on the descending path. Go through a gate, cross the road and head straight ahead on the path parallel to the entrance to the Graire farm. The path climbs and turns left just after a semi-troglodyte ruin until it reaches an esplanade. At the fork, follow the path on the right for about 200m to find a small marker post.
Leave the main path and take a small stony path on the left (not very visible at first) which climbs uphill. N.B. Several tracks on the left are marked on the map but are no longer visible on the ground.
The trail narrows, then passes under the pine trees and finally arrives at a flat area. Ignore the trail that branches off to the left towards Serre Perrier and continue for about 20 metres to reach the Serre Perrier signpost.
(3) Continue on the path on the right towards Pas de la Croix. Higher up, the path becomes steeper at times and ends in a tunnel of boxwood. You will reach a gate marking the arrival at Pas de la Croix.
(4) Turn right to make a round trip to the plateau, which offers a beautiful view. Please note that depending on the season, it may not be possible to reach the plateau as it is a grazing area. Return to Pas de la Croix.
Yellow-green markings
(4) Turn right towards Pas du Buis on a grassy path. Cross a beautiful beech forest dotted with holly trees. At a fork (not visible on the map), follow the path downhill to the left, which joins Pas du Buis.
(5) Turn left through a passage carved into the boxwood. The trail descends along the side of the hill through boxwood at first, then changes slopes and enters a pine forest.
(6) At a fork, follow the path uphill to the left. About 100 m further on, you will come to another fork. Turn left and begin the descent, which is quite stony in places, until you reach a small flat area at the Danier crossroads.
Yellow markings are scarce
(7) Turn sharply left onto the wide path descending towards La Baume-Cornillane. Pass the Buisson de Granon signpost and continue straight downhill towards Serre Perrier. You will come to a junction of tracks (junction of the alternative route).
(8) Turn right onto the track and start the descent. Shortly afterwards, you will see Valence ahead of you. Further down, at a fork, take the left-hand path which runs along the top of the Bégaire stream. You will reach a junction near Mazoyer.
(9) Continue straight ahead on the same path, which becomes flatter. After a bend, leave a path on the left and continue on the main path, which may be muddy in places. You will arrive at a paved section with a gate on the right and the Ferme Bouchet on the left. Follow the road opposite downhill, turn right and continue gently to a dirt car park at Pas du Pont at the foot of a rocky outcrop.
(10) Turn left onto the road to cross this pretty stone bridge. Immediately after, turn left onto a small path that descends for a few metres and then climbs steeply to the right (the route on the map is slightly off). The trail joins a stony path coming from the right (marked in purple on the map), follow it to the left as it climbs.
After following the path more or less along the ridge of the small hill, you will come to a fork. Leave the path on the left that descends and arrive on the right at a viewpoint at the La Roche de Pangée sign. Follow the path that slopes to the right towards the rocks, following them until you reach the Réservoir crossroads.
(2) Follow the same route as on the way there until you reach the ruins.
(1) Descend via the same path to the car park (S/E).

. What's more, there are lots of paths on all sides, so it's not easy
