Description of the walk

Park in the car park at the Village de Prelles.

(S/E) Opposite the car park, before the bridge on the right, take the narrow lane that runs along the left bank of the Gros Riou stream. Pass in front of a house; the lane becomes a footpath. You’ll come out onto a small clearing.

(1) Turn left onto the red-and-white-marked track (which forms part of the GR®653d or the Way of St James).
Stay on this track for about one kilometre before joining the D4 or Route des Traverses.

(2) Continue along this road for 200 metres, where a path begins on the right (signposted). Take this path and follow the markings. Climb gently through the woods and, after a few switchbacks, reach a large meadow just before the hamlet of Bouchier.

(3) Turn left onto a well-marked path leading to the Chapel of Saint-Hippolyte (a return trip to this chapel is well worth it).

(4) Return to the meadow at the previous crossroads.

(3) Turn left again, heading towards Bouchier, and rejoin the GR®.

(5) At the entrance to Bouchier, a signpost indicates the various directions.
Turn right towards Belle Combe, a wide track running due north to La Blétonnée and the hamlets of Le Sapet and Ratière; this track forms part of the GR®50, the Tour du Dauphiné.
You’ll reach La Blétonnée about 3 km further on, where there are several chalets to the right of the track. Stay on the track and, after the second chalet, in the bend to the left, look for a path on the right.

(6) Turn onto this path and head down into the woodland known as the Paroir.

(7) At the first junction, turn left and continue down the winding path. You’ll come to a large cairn on your left; take the path on the left, which leads onto a track. Head left and cross the Torrent du Gros Riou via the footbridge.

(8) Continue down the slope, reach the houses at the top of Prelles and return to the small clearing you passed at the start.

(1) Return to the car park via the same route as on the way there (S/E).

Notes

There’s no water along the route; you’ll need to head into Bouchier to find some.
Take plenty with you, as it gets hot in these woods in summer.
Saint-Hippolyte Chapel: a remarkable view over the Durance valley and Briançon.
GR®653d: this is the Way of St James. The ‘d’ stands for Domitian; indeed, this route is the Via Domitiana, which enabled (and still enables) pilgrims to link two iconic cities: Rome in Italy and Santiago de Compostela in Spain. From Montgenèvre to Rome, this route is also known as ‘Les Clefs de Rome’.
It is worth noting that the GR®653a has just been signposted (the FFRP guidebook is now available): the ‘a’ stands for Aurelian. This is therefore the Aurelian Way, which also leads to Arles but via the south...

Worth a visit

Briançon, the Vauban town, with its forts.
Montdauphin and its ramparts, also designed by M. de Vauban.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

At La Blétonnée, heading towards Prelles, the path doesn’t exist – or no longer does – whether you’re at the first or second chalet. There are two options: either turn back or carry on to Le Sapet so you can head down to Prelles.
It’s a bit disappointing....

The directions aren’t clear enough; it should say: “Cross the road, turn into the cul-de-sac and walk right past the right-hand corner of the pink house; you’ll feel as though you’re in their garden.”
At Bouchier, the sign reads 1508m, not 1523m; it points towards COMBE BRUNE, not Belle Combe

At La Blétonnée, it should say “stay on the track and just after the second chalet…”

Finally, we didn’t see a cairn on our left

The walk after the hamlet of Les Bouchiers was a bit of a slog along the stony path, which, of course, wasn’t in the sun.
I had trouble finding the path down through the forest because the names of the chalets (La Blétonnée and Le Sapet) weren’t there. So I turned back before going any further, and after looking carefully, I finally found it…!
And I found my car again.

As the road to Prelles was closed, we set off from Les Vigneaux towards La Croix de la Salcette. It was a long climb, somewhat exposed in places: steep slopes, loose scree and very narrow paths. Once we reached the plateau, our troubles weren’t over yet. Just past a Black Cross, there’s a tricky section where you’ll need to use your hands (it’s best not to be afraid of heights).
From La Croix de la Salcette onwards, it’s plain sailing. To find the descent path, be sure to keep left and not head towards the valley on the right, so as to pass between the ‘jaws’ of Montbrison. Join the track and turn right towards La Bétonnée and the village of Bouchier (which is very pretty). One last effort to climb a little further up to reach a balcony-like path and make your way back to Les Vigneaux.
All in all, a long and gruelling hike, but one that’s well worth the effort and the slight pangs of regret you might feel at the start.

I went on this walk yesterday, Saturday 6 February.
It’s a moderately difficult hike, very pleasant and with a gradual climb.
To reach the Hippolyte Chapel, don’t make the same mistake I did by climbing up on the left; instead, take the barely visible path that goes round the headland on the right (don’t hesitate to walk right to the edge of the meadow).
The path was partly covered in snow (not very deep but definitely there), particularly on the Bouchié–La Blétonnée section.
In fact, at this far end (N44 51.563 E6 33.841), because of the snow, it took me a while to find the path back.
There is a chalet there (on the right as you go up). You need to head down towards this chalet (which is surrounded by ruins), go round it from below, and the path will become visible if you know how to follow animal tracks.

A walk I went on in early February; there was a bit of snow on the path, but it was a pleasant, gentle walk and the route as a whole offered a chance to discover the Durance valley from a different angle.
