Description of the walk

Departure at the foot of Mont Chiron on the RD21.

(S/E) Cross the main road and take the small tarmac road opposite.

(1) Take the first path on the left towards Martel. Cross Martel, pick up a small road, cross the Dunière on the small bridge, and reach the hamlet of Lafaurie.

(2) At the hamlet of Lafaurie, take the first road on the left towards the hamlet of Chazalet.

(3) Pass the first house in the hamlet and take the path on the right. Walk about 100 metres, then follow the path that branches off to the left under the stone wall. At each intersection, stay on the path going downhill until you reach a large meadow. Be very careful: at the caravan, the path branches off sharply to the right to join the Dunière.

(4) Cross a small footbridge and continue on the path that climbs up opposite. Look for thePR® markings (white and yellow) on the fence posts, follow them and turn left to reach a small tarmac road. Turn right onto the road towards the hamlet of Dunière.

(5) Just before the transformer, take a path on your left that climbs between orchards and woods. Keep heading south-southeast to reach the D13.

(6) Turn left and then immediately right. Then keep to the right to pass through the lower part of the hamlet of Collanges. Just before the road (D13), leave the path that leads to it on your left and continue on the right to Ranchi. Go straight ahead and go through a small gate: you have just entered a park, so close the gate behind you as there are animals inside.

(7) Quickly take the path on your right that descends to a small river, which you must ford. The path then climbs back up to the D13 at the hamlet of La Chabane. Follow the D13 to the right, heading west, for about 500 metres.

(8) At a bend, take the path on the left that climbs through a chestnut grove and leads to a four-way crossroads where you will find thePR® trail.

(9) Follow it to the right, pass in front of a free-range pig farm in an oak forest and continue straight ahead to a small road. Cross and take the road opposite to reach Saint-Jean-Chambre. Pass in front of the church then turn right to reach a crossroads (cross).

(10) Take the small road opposite (marked in red and yellow bythe GR® de Pays de Vernoux) which quickly gives way to a path. Just before reaching the main road, take the path that descends to the right, goes into the woods and then climbs up to a small road. Follow it to the right and, just before the buildings at Jours, leave it and turn left onto a path towards Croix du Loup.

(11) At the crossroads, follow the small tarmac road to the right. In a bend, just above the Razes house, leave the tarmac road and take the dirt track straight ahead. Continue straight ahead, ignoring the turnings on the left and right, until you reach a new road, which you should follow to the right for about 500 metres. You are now in a fairly dark pine forest.

(12) Take the track on the left, which first descends and then climbs rapidly to lead to the sources of the Dunière.

(13) Continue along the path, which climbs again to the Maison des Mottes.

(14) Turn right, along the fence of the meadow, onto the path that descends gently. At the fork, turn left to overlook the Combe farm and continue to a track just opposite the starting point (S/E).

random route for experienced hikers. The start indicates a first path with a downward slope (dangerous), the second path on the left joins the first, but there are no signs indicating Martel. The first hamlet encountered is Martel, after confirmation.
arrival at Chazalet: impossible to find a path descending to the right. You have to go back and, at the Chazelet sign, take a path on the right.
Arrival at a large meadow, no indication whether to turn right or left; in fact, you have to turn left and descend towards Duniere. No caravans, after the footbridge, no white and yellow markings, so I crossed another uphill meadow to reach the road leading to Duniere
Point 5 is clearly marked. The path turns to the right, heading south-southeast
Unable to reach the D13 departmental road, path cut off by ploughing, so return to the car

Taken on 10 June 2025. LELETTE
A very beautiful hike, with lovely woodland,
lots of flowers called foxgloves. Birdsong.
One small downside between the 6th and 7th: you arrive at a small hamlet that you shouldn't cross, but instead go up to the left, go around the hamlet and you'll find the No. 7 sign to go down to the river.
We will happily do this hike again in September.
I recommend it to anyone who enjoys hiking.

A very pleasant walk in the Ardèche countryside. The route is varied and not too difficult, making it suitable for the whole family. We did it in May when the broom was in bloom... a real treat.

A beautiful hike under a slightly yellow sky due to the sirocco wind. A little trouble between 3 and 4 finding the right path.

The map provided for this hike is an IGN map on the same scale as the TOP25, so it is just as accurate.

Hi

So, how can I put this
8 hours, 25 kilometres???
Everything started well. I found the starting point easily. I only had the VISORANDO map, which was a big mistake.

At No. 4, cross a small footbridge and continue on the path that goes up opposite. => No more footbridge, or I couldn't find it, but I doubt that, so I crossed the dry stream, following the tracks left by farm machinery.
Of course, at the exit, I couldn't find the path, so I went back up the farm track and ended up on the road ten metres to the left of the PR, so nothing complicated.

At No. 5 Just before the transformer, take a path on your left that climbs between orchards and woods. Keep heading south-southeast to reach the D13.
I think the " just before " is the mistake. I suppose the "just before" is about 100 metres away. I didn't go back to check after the hike.
So when you reach the transformer, just before it there is a path on my left that also climbs between orchards and woods.
After a nice climb, I ended up in a cornfield, continued through the woods, found some paths, and ended up at "Serre de la Chave". Tired, I used my compass as indicated, left a wheat field, took the road, and ended up at "Ponce". I followed the road to "the peatlands" where I rejoined the No. 6 trail.

From No. 11

"Continue straight ahead, ignoring the turn-offs to the left and right until you reach a new road."
Continue straight ahead ? Leave the turnings on the left and right?
What does "straight ahead" mean in a wood with winding paths? Do we follow the trail that shows us the main path? At an intersection, there is a path at 90° to the left, so I ignore it. A descending path with an open metal barrier prohibiting motor vehicles due to a catchment area, but given the vegetation, it is rarely used. It's an excellent landmark, so I thought that if the hike went through there, it would be marked as 11, especially since it's a PR, so I continued on the main trail. I ended up finding three or four other trails that ended in dead ends.
So, after much back and forth, I took the water catchment barrier. And, oh miracle, there it was.

When you're mapping a hike, you have to be very precise. This can be useful if you're not using an app.
I hadn't bought an IGN map, as I'd never had any problems with this before. I should have, but for a week I didn't see the point.
I may be wrong, but the route was designed to be used 100% with an app.

Luckily, I was on my own, because with the 28°C heat and the navigation errors, it would have quickly turned into a headache with a group.

It's not the fact that I walked for 8 hours and covered 25 km in the heat that bothers me, but the impression of the landmarks.

So be more precise next time.

The barrier, the PR, if to find a path you have to go to a physical landmark, such as a transformer, and retrace your steps for 100 metres, and take the path that goes up... Indicate it clearly.

A superb hike, even if you don't always have a 360° view. Well done if you did it in four hours – it took me almost seven! For me, the hardest part was finding the path after the footbridge at No. 4. However, I recorded 18 km and 540 m of elevation gain on the same route! Perhaps because I did 8 to 10 km on the road.

A lovely walk, with no major difficulties either on the route or in the description. Beautiful views of the Alps and the Vercors on one side and the Mézenc on the other. The route is often in the undergrowth, which is a bit frustrating at this time of year (March), but I think it must be lovely in summer.

A beautiful, peaceful hike. In terms of time, it takes about 4 hours at a normal walking pace (70 years old). I don't know if the 5 hours 35 minutes given includes breaks? There is a slight discrepancy at marker 2 (Le Chazalet), but with a 1:25,000 map, there's no problem. Thank you for the route.

Hello

Many forest paths with no views. Nothing exceptional about the route. If you want to go hiking in the area, choose "Les Corniches de l'Eyrieux" on Visorando instead. Happy hiking, everyone. The Ardèche is beautiful!
