Pas de Jubéo via the Riou Gorges

The Riou gorges and their numerous pools offer a remarkable natural spectacle and a pleasant way to cool off. And as you approach the Jubéo pass, you might think you're on the road to the explosive film "The Wages of Fear".

Description of the walk

Parking is available near the town hall on the D94. Markings: Yellow (PR®) and partly yellow and red for theGR® de pays Tour du Buëch.

(S/E) Take the road towards the Chapelle Saint-Jaume and reach the hamlet of Saint-Genis after a wide right-hand bend at a three-way junction.

(1) Take the right-hand road down towards the cemetery (see Practical Information section). After leaving the hamlet, continue to thefirst hairpin bend on the right.

(2) Continue straight ahead along a path that leads to a meadow after a wide right-hand bend.

(3) Turn left onto a short, steep climb and rejoin theGR® de Pays trail.

(4) Turn right, stay level until you reach the stream and come to an intersection near a stone bridge over the Riou (start of the circular route).

(5) Leave the small bridge on your right, which is the return route, and follow the right bank of the stream through the increasingly narrow gorges.

(6) The path crosses the Riou for the first time via a stone bridge that allows you to cross to the other side.

(7) After passing through a small tunnel, the path continues along the left bank, then turns right, leaving the Riou for the Ravin de Saume Longe. Climb away from the stream to reach a spur with a magnificent view. Climb a few metres to reach a crossroads.

(8) Take the path on the left (signpost) and you will reach the Riou stream again (pools).

(9) Cross the Riou a second time via the footbridge and follow the right bank again, overlooking the torrent. The path joins a track in the forest. Follow it north to the Jubéo forest house and then the picnic area (fountain/signpost).

(10) Take the track on the right towards Pas de Jubéo, which heads south. At a hairpin bend to the left, continue straight ahead and, on leaving the forest, you will arrive at Pas de Jubéo.

(11) Enjoy the view. From there, you will walk more than 5 km on DFCI tracks. After the bend, it heads east and quickly reaches a track intersection.

(12) Turn right, then right again at the next fork. After a sharp right-hand bend, pass a DFCI water tank on your left, leaving the forest road just before you reach the Saint-Lagier spring.

(13) Continue straight ahead at the same altitude; the track makes numerous turns in a north-easterly direction until it reaches a more pronounced left-hand bend.

(14) Enjoy a beautiful view as you cross a spur (short detour to the right), then reach an intersection with a path marked by a post. You can shorten the circular route by descending to the right towards point (8).

(15) Stay on the track for another 300 metres or so and, after a right turn at Ravin de Saume Longe, you will reach a clear left turn.

(16) Leave the track via an old path on the right (DFCI water tank below). Begin the descent, first via an old track that joins an old path further on.

(17) Follow it to the right, descending in hairpin bends (traces of old stone walls). Return to the Riou torrent and follow it on the left bank to the small stone bridge (end of the circular route).

(5) Turn left in the opposite direction to the outward journey to return to the Saint-Genis car park (S/E).

We took a slight detour to return to the starting point.
But it didn't matter, it was beautiful.

Hello
For your information, the path through the marl has been repaired (at the start of Rue de la Combe).
I couldn't believe it. It avoids the big climb at the start and the steep descent on the way back!

A beautiful hike, without any particular difficulty, offering lovely views around the Jubéo Pass.
The path is well marked – red and yellow, then yellow.
At point 15, we preferred to head for the gorges (point 8) to enjoy different views and lighting on the gorges.

Hello, we started the walk at point 10, a nice car park, and had lunch at the Riou lake.
An easy and very pleasant walk.

A lovely circular route starting from St Genis, very well marked trail, the Riou Gorges are magnificent.
One slight downside: between points 10 and 16, there is a long stretch along a forest track.
