Start from the car park on the Place de la Mairie in the village of Le Garn.
This route is well signposted in yellow and white. There are no ford crossings on this route.
(S/E) From the car park in 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 ahead on the same road.
(1) At La Piscine, which is actually a small pond, follow the road to the left. At the first crossroads, continue straight ahead.
(2) At the second crossroads, turn right, heading north towards La Flassade, and follow the road, which soon gives way to a path. Keep to this path, ignoring the various paths that cross it.
(3) At the junction of tracks, the La Flassade mast, and also the DFCI (fire-fighting service), turn right and follow the GR®4. Reach the Terme Rouge mast, near a cistern.
(4) Leave the GR®4and follow a path to the left down into the Combe du Cros. This path is quite difficult and very stony.
(5) At the first crossroads since the start of this descent, follow the left-hand path, which can be very steep.
(6) At the Mât de la Combe de Cros, overlooking the River Ardèche, turn right and follow the river along a path that alternates between short climbs and descents, sandy beaches, limestone rocks and wooded areas... A little further on, leave the path leading up to La Flassade on the right, and continue straight ahead on the path skirting the river and the Plaine de la Cathédrale. The path gradually rises. Reach the site of the Maladrerie des Templiers.
(7) Continue to the left, cross the site and then, going back and forth, take a small, well-marked path on the left (not signposted) up to a summit.
(8) Enjoy the superb view of the Cirque de la Madeleine. Retrace your steps as far as the Maladrerie des Templiers.
(7) Return to the signposted route after visiting the site. To the left, towards Les Ingranatières, head up to the plateau along an attractive path with steps cut into the rock and a safety cable, which overlooks the meander of the Templiers. Make sure you stay on this path and ignore all the various paths leading to it.
(9) At the Ingranatières mast, cross the GR®4and continue straight ahead on a track.
At the first crossroads, leave the track and take a path to the left. Further on, cross a wide track and continue straight ahead.
(10) At the wide track, follow it to the left for a few metres. After the first bend, turn left onto a path heading south-south-east, which leads to the rare remains of the ancient Clos des Mules oppidum.
Shortly afterwards, this path branches off at right angles to the 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.
Map/land discrepancy: the path/road intersection is to the right of the oratory (not to the left). You can therefore go and see the small restored chapel on the left. Continue along the Route de la Capelette. At the next crossroads, continue straight ahead. After a few metres, turn right. Cross the Rue des École, and a few steps to the right you will find the Place de la Mairie and the car park (S/E).
