Park near the main square in Jaujac.
(S/E) Cross the square, take the passage between the houses (Tourist Office), follow the street to the right to reach the Pont du Chastelas. On the way there, the yellow and white markings are still clearly visible.
(1) From the bridge, admire the old village of Chastelas and, downstream, the beginning of the basalt flows from the Jaujac volcano. Take the road to the left of the bridge and then, a few metres further on, the path on the left that descends towards the Lignon.
(2) Walk past an old silk mill, where the mechanism that transmitted the rotational movement is still visible at ground level. The path follows the old water supply pipe.
(3) You will arrive at a large square building that was once an oil mill. Cross the bridge and climb through a wood to the Château du Bruget. Before the château, descend slightly to the left to pass below the building, then climb up through the holm oaks and join a road.
(4) Follow the road to the left. After 100 metres, take the road on the left. Pass another crossroads.
(5) At the next crossroads, take the path on the left which passes through Brunissard, then Peyreplane, continuing to follow the markings. You will come to a crossroads with some very beautiful paths lined with old walls.
(6) Follow the path downhill to the left.
(7) Join the road and follow it again to the right. At Dabrigeon, take a path on the left and cross a superb old bridge over a beautiful stream.
(8) Continue to the left of the bridge, then the path veers to the right to follow the Lignon. A little further on, on the left, there is an arch from a bridge that was washed away by the river.
(9) At Lioure, join the road that leads to La Souche, crossing the bridge over the Lignon.
(10) After the bridge, cross the D19 and take the first path on the left, called Chemin des Endettés. Follow it straight ahead to the Château de Charay (or Charrail).
(11) Join the D19, follow it carefully for 100 metres to the right, take a path on the right between the walls, join a tarmac road, follow it to the left to join the D19. Follow it again for 350 metres to the right.
(12) After La Croze, take the path on the right to the hamlet of Les Peyreyres. Continue straight ahead on the road after Les Peyreyres for 200 metres.
(13) Take the shortcut on the left that cuts across the hairpin bend. Continue down the Peyreyres road, passing close to the hamlet of Basses Peyreyres, and cross the Peyreyres stream via the bridge.
(14) Just after a new bridge over the Ruisseau de Sarrayou, turn right onto the path that climbs into the forest. Pass two hairpin bends, then a barn on the right. Be careful, this is where people get lost, as there are hardly any markings. Look for the path that climbs steeply to the right. If you reach a three-way junction, you have gone too far.
(15) Climb the steep path to the D5 (Col de la Croix de Millet road), follow it to the right for about 50 metres, then take the small road on the left towards Cheylas. Before the hamlet, take the path on the left towards Fougeyrolles, descend again on the left via the small road that rejoins the D5, which you follow this time to the right downhill to La Mercerie.
(16) At the La Mercerie crossroads, leave the D5 on the left, cross the hamlet and descend along a path to a small road, which you follow to the right. Keep left at the next crossroads, then go straight on to reach the stream and then the D19 via the path between the houses.
(17) Follow the D19, which can be very busy in season, with caution, to reach Jaujac and the starting point (S/E).
