Côte Blanche

The absence of houses gives this hike a wild feel. This route, which takes us to an altitude of 1,000 metres, offers beautiful views of the Trois Becs, the Saou Forest, the Ambel Plateau, the Rhône Valley and the Monts Ardéchois.

Description of the walk

On the D70, take the D70B departmental road towards the Blache neighbourhood. Pass the recycling bins and park on the left-hand side of the gravel path, which is the starting point for the hike.

For the entire hike, follow the yellow and green markings.

(S) Follow the marked path to the south-west, towards Les Vingt-Cinq.

(1) After about 800 metres, leave the first path on your left and, 100 metres further on, ignore the second path, also on your left. Continue for about 50 metres and take the path on the left that descends into the valley. Follow it for about 900 metres to reach Les Vingt-Cinq.

(2) At the signpost for Les Vingt-Cinq, turn right and then immediately right again. Climb back up towards Perrache on the path parallel to the one you have just taken. After about 500m, leave the path on your right and keep heading north. After 200m, ignore the path on the left and stay on the most marked path for about 1.7km.

(3) At the crossroads, take the path opposite. Follow it to the summit (1076m). Once on the plateau, keep to the yellow and green markings and follow a fence southwards.

Enter the forest and stay on the main path, keeping south to reach Perrache.

(4) At the Perrache signpost, turn left towards Lozeron.

(5) After about 400m, at the signpost at an altitude of 802m, leave the path on the right and continue straight ahead towards Les Vingt-Cinq.

(2) At the Les Vingt-Cinq signpost, to return, follow the same route you took on the way there.

A lovely walk.
8 April: perfect, as I was all alone in the world amidst beautiful countryside coming to life in spring.
A stunning view.

This route is certainly interesting, but you sometimes feel like you're disturbing the few local residents: blocked paths, "dangerous dogs" signs, etc.

The climb is steep, but the reward is a beautiful plateau of dry grass with some views. We only encountered one family. In my opinion, a GPS is essential for a peaceful hike

The departure point is at a place called Les Blaches.
It is easy to reach via a wide stony path.
The climb up to the Côte Blanche is long but gradual, and not particularly difficult for experienced walkers.
Be careful to follow the sometimes "discreet" markings, as the final stretch of the path is very narrow and overgrown. The arrival at the Côte Blanche is a real reward for the view it offers.

I couldn't get past number 3 because there are so many turnoffs that I couldn't find the right one. I followed the valley, which was a beautiful walk, but I was disappointed. Don't do this hike during hunting season; there was a hunt going on. I only navigate with a paper map and rarely get lost

We left Plan-de-Baix, taking a section of the GR trail and passing by the Ferme de la Sauzy. This adds 4 km (2 there + 2 back). You do walk a bit on the road, but it's fine (6 hours and 10 minutes with breaks). Point 3 wasn't a problem, but we lost the trail a little after that and before the ridge. We had some trouble finding the path on the ridge.
There are beautiful views of the Vellan plateau, the Vercors and the Trois Becs, and you can even see Valence once you're on the ridge.

hike done in clear weather with beautiful sunshine, so the views were superb: the Vellan cross, the Three Peaks, views of the Vercors, etc.
Nice climb to reach the plateau. And there we couldn't find the path even though we followed the fence, probably because of logging... No more signposts either. After crossing meadows and undergrowth, we managed to find it again... 2 km more and a hundred metres of elevation gain! Luckily, the weather was very nice.

Hello, can anyone tell me if you come across a Patou on this route? I did it last year at the same time and there weren't any, but now I'm not so sure. Thanks

Beautiful hike with stunning views of the Vercors. Be careful when walking along the fence heading south, keeping it on your right as you follow the path that enters the forest towards Parrache.

We did this with a group of 11 people in beautiful weather. We started from the chapel at the entrance to Plan de Baix, which is a 19 km route.
The climb after point 3 is quite steep, but once you reach the top, you forget all about it because the view is magnificent.
A very beautiful hike that I would definitely do again. In fact, I found the distance a little short, but there's no point in trying to make it longer, as it allowed us to visit Plan de Baix.
Thanks to whoever created this route.

An additional 1.7 km detour suggested in the comments to reach the highest point in the area is magnificent. I recommend it and it would be good to include it in the hike! Magnificent view!
Be careful of the markings, which led us astray at a fork in the path. The GPS route allowed us to find our way back.

Hello,

An interesting route starting from Plan de Baix. No significant difficulties apart from hunting for large game in the woods of the Côte Blanche (but even that didn't bother us), offset by the autumn colours. Very pretty views of the Vélan.
