Start at the car park in the village of Rimplas near the church.
(S/E) Take the paved stairway that climbs north of the village - marker 157a.
(1) Turn right and arrive at the Serre road in a bend, continue along this road to the end at a transformer.
(2) The trail starts to the right of the transformer. Begin a fairly steep climb heading north and you will reach two ruined chalets - marker 158a.
(3) At the marker, stay on the path on the right and continue north, passing marker 158, going over a reservoir and arriving at marker 159.
(4) Leave the Rimplas cattle trail on your left. Follow the direction of Rouagne. Walk east on a rocky path lined with thorny bushes for about 1.1 km. Enter a more pleasant area of undergrowth and reach a Y-shaped intersection. Please note that there are no signs or yellow markings.
(5) See the practical information for this point. At this fork, take the path on the right and gradually begin the descent. After a few switchbacks, you will arrive at a small plateau facing some rocks.
(6) Do not go to the rocks but turn left immediately to go around them. Continue the descent to marker 152. Head towards a ruined building and a sign indicating La Bolline.
(7) Follow this pleasant path to reach marker 151 at the entrance to the village of La Bolline.
(8) At the crossroads, leave the main road and turn left onto Rue du Pont, to the right of the bus stop. Cross the village via Rue Centrale. At Café Edhy, turn right and cross the main road at marker 147. Heading south, take Chemin Saint-Macaire to rejoin the GR®52A at marker 148.
(9) Continue west towards Rimplas. On the GR®52A, follow the fairly steep descent, guided by markers 149 and 150, to reach a bridge over the Vallon Gros torrent.
(10) After the bridge, the path climbs again to Rimplas. Stay on the GR®52A, pass marker 155 and come out onto the M2565 at a hairpin bend. Take this road carefully uphill on the right for about 200 m until you reach marker 154.
(11) At the right-hand bend, take the path opposite, which continues to climb, pass markers 153a and then 153, and reach the entrance to Rimplas and the car park (S/E).
