Start from the car park on the Place de la Mairie in the village of Le Garn.
This route is very well signposted in yellow and white. There are no fords on this route.
(S/E) From the car park on the Place de la Mairie, take the Route de la Piscine on the right, heading north-west towards Le Puech-Guin. At the various junctions, continue straight on along this same road.
(1) At a place called La Piscine, which is actually a small pond, follow the road to the left. When you reach the first junction, continue straight ahead.
(2) At the second junction, turn right, heading north towards La Flassade, and follow the road, which soon turns into a track. Stay on this track and ignore the various paths crossing it.
(3) At the junction of tracks, the La Flassade mast, and also the fire defence access road (DFCI), turn right and follow the GR®4. You will reach the Terme Rouge mast, near a cistern.
(4) Leave the GR®4 and follow a path on the left down into the Cros valley. This path is quite difficult, very stony.
(5) At the first junction since the start of this descent, follow the path on the left, which is sometimes very steep.
(6) At the Mât de la Combe de Cros, overlooking the River Ardèche, turn right to follow the river along a path alternating between short ascents and descents, sandy stretches, limestone rocks and wooded areas... A little further on, leave the path leading up to La Flassade on your right and continue straight on along the path running alongside the river and the Plaine de la Cathédrale. The path will gradually climb. You will reach the site of the Maladrerie des Templiers.
(7) Continue to the left, cross the site, then, on the return journey, take a small, well-marked path on the left (unmarked), leading up to a summit.
(8) Enjoy the view of the Cirque de la Madeleine, which is quite superb. Retrace your steps back to the Maladrerie des Templiers
(7) After visiting the site, rejoin the marked route. Turn left towards Les Ingranatières and head up towards the plateau via a lovely, well-maintained path: steps carved into the rock and a safety cable, overlooking the Templiers meander. Stay firmly on this path and ignore all the various paths joining it.
(9) At the Ingranatières marker, cross theGR®®4and continue straight ahead along a track.
At the first junction, leave the track and take a path on the left. Further on, you’ll cross a wide path; continue straight ahead.
(10) At the wide track, follow it to the left for a few metres. After the first bend, take a path on the left, heading south-southeast, which leads to the few remaining ruins of the ancient oppidum of Clos des Mules.
Shortly afterwards, this path branches off at a right angle, heading west, and joins a track.
(11) Follow it to the right for a few metres, then turn left at a right angle to take a path heading south, leading to a road.
Discrepancy between map and terrain: the path-road junction is to the right of the oratory (not to the left). You can therefore visit the small restored chapel on the left, making a round trip. Continue along the Route de la Capelette. At the next junction, carry straight on. After a few metres, turn right. You will then cross Rue des Écoles, and a few steps further on to the right you will find the Place de la Mairie and the car park (S/E).
