Yellow markings for the Gresinhòla
(1) Turn left immediately to follow Ruelle de Carguemech, between the café and the large stone cross of Alric. This Garmiech hill leads onto the D9.
(2) At the D9, walk a few dozen metres to the right, then, before the Grailhettes campsite, take the grassy track on the left. After 50m, ignore the track on the left and continue straight on along the narrow path opposite. This runs parallel to the D9, climbs steadily and joins the main road at a bend, at an elevation of 282m.
(3) Cross the road and continue climbing through the woods. Pass through two gates halfway between the bend and Grézelles Basses. Reach the access road to Grézelles Basses.
(4) In front of the farm access road and to the left of the road, there are two PR® signposts. Follow the signs for Gresinhòla. Keep heading south then south-west. Pass Grézelles Hautes. Cross the Pézatgé. Approach Les Fontanelles. You have reached the highest point of the route.
(5) Turn left onto the path beneath Pézatgé. You will come to a road; walk 50m to the right. In front of Mayrin, turn left. Continue to a T-junction with a dirt track. Turn right to reach the junction with theGRP® Cordes-Penne-Coustous, at an elevation of 376m.

(12) Follow the street to the right to reach the centre of Roussayrolles. Pass in front of the town hall and then the cemetery.
A visit to the church is a must. The church in Roussayrolles dates from the13th century.
On leaving the cemetery, turn left. Take the first dirt track on the right. At the T-junction, turn left. The track runs alongside the Touron farm, where cows graze freely. Please ensure you close the pasture gates behind you.
(13) At the road, cross over and continue straight ahead. 100m further on, at the fork, keep right onto the gravel track. Pass a tree that has swallowed up a small signpost (on your left).
(14) Turn right onto the dirt track. Follow the yellow-marked path, which winds through the woods a few times, passing a wooded pasture. Walk alongside the cattle enclosure, then follow the path until you reach the Ruisseau de Bonnan, at an elevation of 258 metres. Cross the ford just before a fork in the path.
(15) At the fork, take the wide track on the right. Follow this track to the right of the stream. Halfway along, you will come across the ruins of the Madeleine sarcophagus. You will reach a bridge.
Yellow markings – Bonnan Valley
(16) At the bridge and in front of the signposts, follow the PR® Bonnan Valley trail by turning left and crossing the bridge. Continue to the right towards the petrified waterfall. In summer, the waterfall is dry, but in winter, the spring flows abundantly or becomes covered in stalactites if there is a frost. It is possible to walk up to its source.
(17) Tuff waterfall. Continue along the stream until you reach the next bridge and cross it (see the Bonnan waterfall a little further downstream). Note, as you pass, just before the bend towards the bridge, a huge, centuries-old elm tree on the right.
At the T-junction, turn left.
(18) At the road, head up the hill opposite. Stay on this road, ignoring the one you cross after the bend, in front of the white wrought-iron cross. Walk gently downhill to the bottom of the village.
(1) At the Alric cross, retrace your steps to return to the Salle Communale car park (S/E).
