Description of the walk

The new starting point is at the cemetery, which avoids any neighbourhood disputes.

(S/E) Leaving the car park, with the cemetery on your left, turn right onto the path heading south-southwest. You will reach a fork at an elevation of 634 metres at Col de la Croix.

(1) Continue straight ahead (west). The path is quite rocky but does not present any major difficulties.

(2) You will come to a path coming from the right; turn slightly left (south-west).

(3) At the fork, take the path on the right (west) to elevation 730, at Goulet de la Verrière.

(4) At the crossroads, it is impossible to climb the ridge that leads to Serre de Leyrier.
Take the path opposite that descends into the woods. Ignore the paths on the left.

(5) At an altitude of 600 m, take the path on the left and continue downhill through the woods. You will come out onto a small road.

(6) Follow it to the right. At the crossroads that immediately follows, turn left. In a left-hand bend, leave the road and take a path that branches off to the right at an acute angle.

(7) At the next intersection, turn left. Enter the hamlet of Vaneilles and, at the T-junction, turn left. At the end, turn right.

(8) Immediately afterwards, turn left at the hairpin bend (follow the signs for Le Chambon-de-Bavas then Serre de Gruas). Go up the winding road and cross the D265 road. Ignore a turn-off on the left.

(9) At the next junction, turn right. Ignore a turn-off on the left and, in a right-hand bend, take the path that branches off to the left. Join the D265 road and follow it to the left (west).

(10) Above the village of Le Chambon, leave the road and take the path on the left that climbs to the edge of the forest. Then take the first path on the right and, at a fork, take the path on the left. At a T-junction, turn right and you will immediately reach an elevation of 514 metres, at another fork.

(11) Take the path on the left. Then take the first path on the right and climb the switchbacks. Return to the path you left at the previous point and follow it to the left.

(12) At a fork, take the left-hand path. Then take a sharp left turn to cross the Ravin des Biousses. Join a small road.

(13) Follow it to the right. This will take you to Croix de Gruas at an elevation of 778 metres.

(14) Take the first path on the right. Then ignore a path on the right. At the T-junction, turn left to reach the ruins of the Saint-Quintin farm, a building reminiscent of the region's farming history.

(15) Turn sharply left and follow the main path north-northeast. You will come to a track; follow it to the right. Ignore a turn-off on the right.

(16) At a hairpin bend to the right, continue straight ahead on a path towards Grand Bois. Follow this well-marked path which winds through the woods.

(17) At a fork, at elevation 611, turn left, heading due east. The path climbs and narrows, turns north and joins a fork passed on the way out.

(3) Turn right and retrace your steps to return to the cemetery car park (S/E).

Notes

There are no water sources along this route, but if you venture a little further into the village of Chambon-de-Bavas, you will find refreshments. Be sure to bring 2 litres of water per person.

The paths are very passable, with only a few very stony sections that may cause problems for older people.
Wear good walking shoes as the distance is considerable.

The route is clear and well marked except for the climb between Le Chambon-de-Bavas (1) and Les Croix de Gruas (14), where most of the markings have been worn away. However, apart from the Ravin du Cros fork, all routes lead to the same destination, the difference being in the elevation gain.

Worth a visit

The climb up to Serre de Leyrier is currently blocked.It can be bypassed to shorten the hike by 500/600 m and almost 100 m of elevation gain. However, the panoramic view of the Vercors, the Drôme valley and the Trois Becs on one side, and the Ardèche Mézenc mountains, Gerbier de Jonc and the network of valleys on the other, is, in my opinion, well worth the effort.

(15) The ruins of Saint-Quintin bear witness to a very significant peasant past in Ardèche, and its architecture could be confused with that of a small chapel. Once again, this detour can be avoided, shortening the route by 600/700 m, with almost no elevation gain.

The final climb up the Serre de la Cheline is for those who wish to reconnect with the panorama encountered at the top of the Serre du Leyrier. It offers a slightly different view of the Rhône, the natural border between the Ardèche and the Drôme.

A lovely, pleasant walk among the chestnut trees... Several beautiful viewpoints. I would happily do it again with my group (this was a reconnaissance walk the first time).

Hello
Hike undertaken by a group of 24 hikers. Very enjoyable, beautiful scenery, lovely chestnut forests...
A few points to note:
- It is no longer possible to climb the ridge that leads to Serre de Leydier WP5. It is all fenced off, and even if you try to go around it, it is no longer possible to get there.
- It is not possible to do the section from WP1 to WP2 on the way back, as it is all fenced off and impossible to pass. You have to take the same route as on the way there.
Everything else is fine.
Thanks to the author for this splendid hike.

Hello
Hike completed by a group of 12 walkers. Everyone thoroughly enjoyed this beautiful route through chestnut, pine and oak trees. Some beautiful views of the Ardèche mountains at the top of Serre Leyrier. Very pretty hamlets including Vaneilles and the charming village of Chambon de Bavas.
We were unable to complete the last small circular, as the path seemed to pass through fenced-off areas that we did not dare to cross. No big deal.
Thanks to the author for this beautiful hike.

A beautiful hike with stunning views. We chose to return via the summit of Serre de Gruas, where the view is breathtaking. The descent into the Eyrieux valley is very pleasant, but the climb back up is a little tough in places; the path is not very visible, but it's well worth the effort once you reach the top. The GPS was a big help. A beautiful walk that we highly recommend.

Note: one of the paths leading up to the greenhouse is virtually inaccessible

Hello, could you clarify? If you are referring to the Leyrier greenhouse from the Verrière gorge, there is a path leading to the top, blocked by a fence that can be climbed over.

It is best to park in the cemetery car park as the owners of the hamlet of Les Prés have asked us to vacate the location indicated on Visorando.
This hike is superb. In the hamlet of Vaneilles, it is worth taking a short detour to the right in spring, as there is a beautiful rose garden and a "bird retirement home".

A beautiful hike, without any major difficulties, in the hills of the Ardèche. The views of the Vercors and the Alps on one side and the Ardèche mountains on the other are simply superb.
