Description of the walk

(S/E) From the Lac des Ramiers car park, turn right onto the Mirabel-Chambaud path for a few metres, then turn left onto Avenue de Baschi for a few metres.

(1) Keep right on Chemin de Tacanet,GR®420, towards Le Gratol, Boffres. At the next fork, go down to the left and follow the Merland stream. Pass the water treatment plant, then join a three-way junction: Les Petits-Ponts.

(2) Go up the small road straight ahead towards Le Gratol, Boffres. At the next fork, turn right. A little further up, walk alongside the Mont Flos farm. Continue to the next fork, just before a hairpin bend.

(3) At this junction, take the road climbing to the left and follow it until you reach the small road leading to the hamlet of Savinas, which you follow to the right. Cross the hamlet and continue along this small road.

(4) At the next crossroads, take the path on the left going up towards the Gratol farm. This path gives way to a trail that passes in front of the farm, climbs above it on the left, then continues through the woods. Reach a wide path and follow it to the right until the nextGR® crossroads.

(5) Continue to the right towards L'Herbasse. A little further on, cross a track and continue on theGRP®420to the next three-way junction.

(6) Continue straight ahead towards L'Herbasse, staying on theGRP® until you reach the hamlet of L'Herbasse. Cross it and continue to the nextGR® junction: turn right towards Col de la Mure-Saint-Julien-le-Roux and join the next crossroads at Lierne.

(7) At Lierne, go straight ahead towards the south, Col de la Mûre, Saint-Julien-le-Roux. Follow theGR®42andGRP®, which is sometimes quite rough.

(8) At the fork, leave theGR®420and continue straight ahead on theGRP® de Vernoux, marked in yellow and red, without ever leaving it, until you reach the Col de la Mure. Turn left and follow the RD21 for about 150 metres until you reach the hairpin bend.

(9) At this bend, take the path winding through the woods to Saint-Julien-le-Roux. Ignore all the paths branching off to the right or left and stay on theGRP® until you reach a small road. Continue straight ahead.

(10) A few metres further on (Vignasse mast), at the crossroads, continue straight ahead towards Vernoux. At the next crossroads (Croix mast), turn left towards Vernoux. You will reach a three-way junction (Clôt mast), follow the path on the right (without leaving theGRP®), which passes through fields, orchards and woods until you reach the road. Follow it on the left for a few metres, then continue straight ahead towards Le Vernet (sign).
At the next junction, do not turn towards Le Vernet, but continue straight ahead, following the path that continues along the road.
Reach a three-way junction, turn right (marker on a rock), go around the field on the left, and the path continues without any problems.
Walk to the D231.

(11) Cross it and follow the path opposite down to the Ève stream. Take the footbridge to cross the stream, then climb up opposite, without leaving theGRP®, until you reach the ruins of the Château de la Tourette.

(12) There are two ways to reach the ruins:
- just before the ruins, theGRP® takes a small marked path on the left which then joins the Chemin de la Tourette and the ruins;
- continue to the right until you reach the ruins, then take the Chemin de la Tourette.

Take the small Chemin de la Tourette road, reach and cross the hamlet of Pailler, continue on theGRP® along this small road, ignoring the various small roads on either side ofthe GRP® until you reach the Montunaud district.

(13) Continue along this small road, without leaving it, towards Vernoux straight ahead for about 500 metres (follow the housing estate, leaving Chemin des Îles on your left).

(14) At the three-way junction, take the small road on the right until you reach the intersection with Chemin du Vernet.

(15) Turn left, then shortly after right onto Chemin Abraham Mazel. Follow it to the D21, cross it and shortly after join the Chemin de Tacanet, which will take you back to the Lac des Ramiers (S/E).

Notes

Hiking boots: trails can be uneven or steep in places (Ève valley)

The hike can be shortened at the point (4) by following the signposted alternative route to the right towards Col de la Mure and Grosjeanne, which does not present any particular difficulties.

The name "Vernoux" certainly originates from the name "Vern", which comes from Auln. "Vivarais" was added later to refer to both the region in which the village is located and the fact that it was home to one of the twelve baronies of Vivarais.

Well described except for one place where the description did not match reality. We went down to the road via another route and rejoined your route further on. A lovely walk with beautiful scenery, definitely worth doing. Thank you for this suggestion

Hike completed on 13 June 2024. A very beautiful hike, I thoroughly enjoyed it. The final climb to the castle is quite challenging

Beautiful hike. We didn't have any problems with dogs. There's a steep descent towards the end before climbing back up to the castle. I think it's better to do it in the direction indicated.

Hike done today, Tuesday 18 April, with a small group of six people.
A very beautiful loop, done backwards to start with, covering 2 km of road at the beginning. Lots of flowers on beautiful trails with stunning views all along the way. The walk is long but so beautiful!
I would like to point out that at the Pailler farm, we were harassed by two dogs (Australian Shepherd type). One of them bit a hiker's ankle, but fortunately it wasn't serious thanks to his high-top shoes. They were very aggressive, and we shouted to alert the owner, but no one came. They followed us for quite a long way along the road, and we had to walk backwards to face them! It was quite stressful!
Thank you very much for the walk.

A very well-described and well-marked hike. Foggy weather but very pleasant woods and a desire to see the panoramic views on a clear day

20 km hike to avoid in hot weather, especially the second part after the Eve footbridge.
Quite a lot of tarmac overall.

The Visorando team is also sorry to hear about this accident. The dog owner's reaction is unacceptable, and as ardechom said, you did the right thing. Nevertheless, it was a bad experience. Good luck and get well soon

Yes, TB, that's exactly what needs to be done. The owner will have to bring their dogs, or at least the dog that bit, in for three visits. You should also report it to the Vernoux Town Hall. Generally, the elected official will take the necessary steps to ensure that it doesn't happen again.
I have encountered the same type of problem in St-Étienne du Serre (the mayor dealt with the issue remarkably quickly), as well as in Piégros-la-Clastre (I did not receive a reply to my email, but the necessary steps were taken, as I was able to confirm). The situation is now back to normal.
I wish you a pleasant day and a speedy recovery.

Thank you for your support. Yes, that's right.
I went to A&E as soon as the walk was over. I was well looked after (stitches, antibiotics, phone number for the rabies centre, etc.). I called the rabies centre in Lyon this morning. They are going to write to the owner, who must arrange for veterinary follow-up...

Hello, sorry to hear about your misadventure. Was it on the road near the Paillet farm that you were bitten? Dogs have no business being on a public road, and certainly not biting people, especially in front of the owner. Did you report the bite?
Have a nice day.

A great hike until the 17th/18th kilometre. Just after Tourette Castle, I was attacked and bitten by one of the two dogs on the farm, right in front of the owner! I was bitten on both legs... Be careful! According to the owner, the dogs felt provoked because I had walking sticks!

Hike done in the opposite direction. Unfortunately, it was cut short by the threat of a storm. We only went as far as the castle ruins, which offer a beautiful view.
To be repeated in better weather.

The only minor drawback of this hike is the road on the way back.
