To get to the start, coming from Aubenas, after the Balazuc junction, the car park in an old bend is on the left of the D104, just after the large viaduct. To avoid crossing the road, you can turn right onto the road leading to the hamlet of Les Louanes and come back in the right direction.
(S/E) Leave the car park and follow the white-yellow marked trail northwards. Cross the stream. At the "Viaduc" sign, turn right and continue to the Serre Bouchet sign.
(1) Go down the path on the right, cross the stream and go back up to Serre Bouchet. Continue following the white-yellow markings. The paths on the right and left shown on the IGN map are not visible. However, at a ruin currently being restored, leave a wide unmarked path on your right. You will arrive at the Serre de Rimbaud sign.
(2) Turn right and follow the ridge path to the Serre Juillet sign.
(3) Leave the path descending to Pradons on your right and take the path on the left. Reach the highest point.
(4) Temporarily leave the white-yellow markings and turn left, ignoring the cross. At the first junction, turn right to rejoin the marked path and continue on the left. This small detour offers a more beautiful view and avoids a stony descent. You will reach a hairpin bend.
(5) Leave the marked path that descends to the left and continue straight ahead on the ridge along a wide path that gradually becomes a trail.
Note: this trail is marked in its entirety on Open Street Map hiking but not on the IGN map.
Pass under an electric fence, walk along an old rusty fence and descend until you reach a path marked in white and yellow again in the hollow at a small pass.
(6) Take it to the right and cross a first stream. Before the second stream, follow the markings carefully, which make a hook to the left then right (elevation 190). Pass the Le Planas hiking sign and continue on the tarmac road towards Pradons. You will reach a crossroads just before the Les Blaches sign.
(7) Leave the markings and take a path that branches off to the right a little way back. Cross the stream and arrive at a path, turn right onto it. You will reach a three-way junction with three paths.
(8) Take the path furthest to the left, ignoring the cross, as the rest of the route is not signposted.
After crossing a stream (channelled by culverts), leave a wide path on the right and left and continue straight ahead on a path that becomes a trail and leads to another stream.
(9) Descend along this stream for about 20 metres, then cross it on rock slabs and climb up the ravine opposite via a path on the right bank. Cross a recently burnt area and you will reach a wider path.
Leave a path descending to the left, cross a stream and arrive at a hairpin bend on the right.
(10) Continue straight ahead, leaving the main path on your right. Pass by a ruin. In the next section, several parallel tracks may cause you to hesitate. The main path follows the ridge very closely and runs parallel to a fence on the left.
(11) At the corner of an olive grove on the left, turn right onto a clearly visible path. Descend to a stream, then turn left and continue downhill, following the stream on its left bank.
(12) At a three-way junction, near a waterfall, take the path on the right and continue until you reach a wider path. Turn right and descend to the stream.
(13) Turn left to cross it. Continue along the path (not shown on the IGN map) to the bridge over the Greenway. Cross the bridge and immediately turn left to descend to the Greenway, which you take on the left, passing under the bridge again.
(14) After crossing over a small road, follow the signs indicating the exit from the Greenway via a path on the left that leads directly back to the car park (S/E).
