Description of the walk

Access to Poët-Laval is via the D540. Park in the car park at the foot of the old village: there are dry toilets in the car park.

(S/E) Walk back a few metres along the road you arrived on, turn right at the crossroads and continue for about 100 metres.

(1) Turn right onto Rue Basse du Pavé, which leads up to the old village. When you reach Rue des Remparts, turn left and then right onto Rue du Château. Further up, cross Rue Neuve, continue straight ahead to pass to the right of the Château des Hospitaliers, then descend towards the cemetery.

(2) At the signpost marked "Poët-Laval vieux village" (old village of Poët-Laval) at the corner, turn right towards Trou du Furet on the tarmac road that runs alongside the cemetery for about 150 metres. At the three-way junction, ignore the path on the left and take the path on the right, which goes around a house further on and begins to climb through increasingly dense vegetation.
Follow the yellow and redGRP® markings and ignore the small paths on the left and right. When you reach a clearing, continue climbing to the Montagne du Poët plateau: a beautiful stone arrow indicates the direction.

(3) When you reach the plateau, turn left and follow a beautiful, fairly steep path that descends towards Trou du Furet.

(4) At the Trou, the wind is strong, but the landscape is worth the descent. There is a lovely view of the village of Eyzahut. Retrace your steps and climb up towards the cliffs to walk along them and admire the scenery. Be careful not to get too close to the rock, especially when the wind is strong! Continue through the pastures: you may see horses, but do not disturb them. Find a well-marked path.

(5) Continue straight ahead. Magnificent beech trees line the path and in April and May, pasque flowers bloom everywhere in the mountain pastures. When you reach the woods, follow the path that descends slightly towards the ravine.

(6) At the crossroads, turn left and follow a beautiful path to the Ruisseau de Salettes stream, which is dry. Continue through the forest to the Rocher de la Tournelle rock.

(7) Take the path on your right that climbs up to La Bisquerie.

(8) If the wind is strong, it is advisable to take a break here, surrounded by anemones, before descending a little and tackling the summit of Serre Gros, where the wind is likely to be very strong.

(9) If there is no wind, it is a real pleasure and a reward for hikers to picnic at the summit of Serre Gros and admire the magnificent landscapes. Descend a little and find a path almost at the edge of the cliff, which is quite steep in places, leading down through the forest to the Col du Pertuis.

(10) At the yellow "Col du Pertuis" sign, ignore theGRP® de Dieulefit, retrace your steps for about ten metres and take a small path on the left. This path first passes through the forest; ignore the path on the right that goes up to La Bisquerie and continue to the large crossroads of the track you took on the way up.

(6) Take a stony path on the left, which becomes an easier track towards the end, and ignore the small paths on the left and right: a GPS device would be useful for this part of the route.

(11) Negotiate the hairpin bend to the left and continue straight on to the car park at the start (S/E).

A beautiful hike with two slightly steep climbs after passing La Tournelle. To follow the route, the GPS track may be useful in two places.

There are markers up to the ferret hole, then you have to follow the GPS tracks carefully.
Otherwise, the path is easily passable. We came across herds of wild horses and the views are really nice.

A magnificent hike done as a reconnaissance on Friday and as a warm-up hike with a group on Saturday. The group found the climbs quite tough but the scenery superb, a very beautiful environment. The GPS proved very useful because only the climb to Trou du Furet is marked; for the rest, it is easy to get lost. The only negative point was that the descent between 6 and 11 was a nightmare for everyone (rocks).
The app displayed several access restrictions, but on the ground we only saw a chain between 10 and 6 with a sign prohibiting access to cars and mopeds.

A pleasant hike, with detailed information.
I did it on a windy day, and it was difficult to stand on the peaks. But in summer, it was refreshing.
The last descent is really covered with stones. You're glad to get there.
Thanks to the creator for this superb route.

I would like to thank the author for a superb hike. A real favourite. No problems with the route. I really liked the 3 peaks, but, honestly, this one will remain my favourite. I recommend it 100%. We had a picnic in front of a beautiful panorama. Sublime... Definitely worth doing again. Thank you, thank you. An easy hike, the last part is a bit steep, but if you go at your own pace and put in a bit of effort, you'll be rewarded... The descent on the way back is easy.

A very beautiful hike, with beech woods and clearings, superb views, and the famous ferret hole! You need to follow the GPS track in some places.
We had to turn back at 8 because of heavy rain and strong winds.
But it was worth it.

A very pleasant hike offering superb views. Due to a hunt and an injured wild boar in the area between the summit of Serre Gros and the Pertuis pass, on the advice of the hunters present, we had to change our planned route to avoid this section, cutting across the ridge and descending on its western side to rejoin the "normal" path further down, leading back to point 6, and continue on without any problems.
Thank you to the author for this wonderful suggestion.

The description is imprecise from the village onwards, even though it would be easy to list the street names without omitting any. Point (2) mentions a three-way junction, but there is only one path that continues on from the tarmac road. Further on, it mentions a clearing that you have to cross, but I don't know where this is. I didn't see any "beautiful arrow".
Point (3) mentions that once you reach the plateau, you have to turn left: ???

On the plateau, you are often on grassland, and the paths start but don't lead anywhere. It's complicated unless you walk along the cliff.

I used my GPS for the return journey, otherwise I only use the description and therefore no GPS track.

Very beautiful hike. At Trou du Furet, be sure to retrace your steps back to the plateau to rejoin the route. Thank you for this trail.

Hello,
A very beautiful hike, I love this place. I've done it twice, once in the spring and yesterday. The plateau is superb with the ferret hole, the horses roaming free, and the magnificent ribbon beech tree. The forest passages and the climb to Serre Gros are very pleasant, and the picnic at point 9 is well worth the effort of reaching the highest point of the hike.
It's true that there are a few nettles (dry in summer) but not in spring around point 10.
The only downside is the descent, which I always find unpleasant and long. I think next time I'll try a different route for the return journey.
The village is superb. I really enjoyed doing this hike again to show it to others. Thank you very much for this route.

A very beautiful hike. I would add to this by recommending the municipal campsite in Poet Laval and a comment from a forester: stunted downy oaks at the start, then Scots pine, then beautiful, large downy oaks and very large beech trees or dense thickets on the ridge. The boxwoods are sculpted by horses. They seem to be recovering after attacks by moths.
Be careful at point 10, as the path to take is in the nettles!

A very interesting hike with the surprise of the Trou du Furet (Ferret Hole) and an encounter with a herd of horses on the Serre Gros plateau. Beautiful beech trees line the path on the plateau, where you will find meadows blooming with pulsatilla anemones. A visit to the village of Poët-Laval on the way back from the hike rounds off the day nicely.
