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 theGR®653dor the Way of St James).
Stay on this track for about one kilometre before joining the D4 or Route des Traverses.
(2) Follow 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, winding your way up in a series of switchbacks, until you reach a large meadow just before the village 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 sign shows the various directions.
Turn right towards Belle Combe; this is the wide track which, heading due north, leads to La Blétonnée and the hamlets of Le Sapet and Ratière. This track forms part of theGR®50Tour du Dauphiné.
You’ll reach La Blétonnée about 3 km further on, where there are several chalets to the right of the track.
(6) Here, you have two options:
- at the first chalet, take a barely visible but wide track; stay on this track heading north to rejoin the south-east-bound path,
- stay on the track and, after the second chalet, take the path mentioned above at a right-hand bend.
Then head down into the woods known as the Paroir.
(7) At the first junction, turn left and continue down the winding path. When you reach a large cairn on your left, take the left-hand path, which leads onto a track; turn left and cross the Torrent du Gros Riou via the footbridge.
(8) Continue the descent until you reach the houses at the top of Prelles, then return to the small clearing you passed this morning.
(1) Return to the car park (S/E) via the same route you took on the way there.
