The summit of the Gorges de la Bourne via the Pas des Rages

Starting from Basse-Valette, the Pas des Rages provides access to the top of the cliffs of the Bourne Gorges. The path then runs along the cliff, offering magnificent views of the gorges and allowing you to discover the Balme Noire cave. In addition to the walk, access to the starting point is via the Bourne Gorges road, one of the most beautiful in the Vercors.

Description of the walk

Set off from the Basse-Valette stopover lodge on the D531. You can park along the access road to the Haute Bourne hydroelectric power station, or a little further on past the lodge in a small car park along the D531.

(S/E) Take the track that passes in front of the lodge and then turns right towards the Pas des Rages. This is a section of^{the GRP®®} Tour des 4 Montagnes, marked in yellow and red.
The route winds its way up to the Pas des Rages: make sure you follow the markings carefully as the path crosses several forest tracks.

(1) At the Pas des Rages, the path joins a wider track which continues to the right. A little further on, you’ll reach a junction with several forest tracks.

(2) Take the^second track on the left (see note in the ‘Practical information’ section). Stay on this track, which is still part of the^GRP®®, until it becomes tarmac.

(3) Just before the tarmac begins, you’ll notice a small path veering off to the right: do not take it now, as this will be the route back. For the time being, continue along the^GRP®® until you reach a hairpin bend to the left: this is the Pas de la Ferrière.

(4) Ignore the first path on the right immediately after the hairpin bend, and take the second one which branches off a few metres further on. It is marked with a blue sign. The path continues through the woodland before reaching the edge of the cliff. The blue markings are clearly visible at the start but become less frequent further on. Continue along the cliff edge.

(5) Gradually veer northwards, moving away from the cliff. Carry on straight ahead, ignoring a few tracks branching off on either side. On leaving the forest, you’ll reach the road leading to Méaudret.

(6) Turn left towards the hamlet of Haut Méaudret. The road becomes a track after the hamlet; carry on straight ahead (ignoring a first track branching off to the left and then another to the right) until you return to the Pas de la Ferrière.

(4) Follow the track back to the crossroads you passed on the way there (which, in this direction, is a few metres beyond the end of the tarmac).

(3) Take the small, rather poorly marked path that descends to the left. The path itself is not signposted, but its start is marked with a cross, corresponding to the^GRP®® markings that follow the main track. After a fairly steep descent, you’ll reach a junction with a wider path.

(7) Turn left to reach the Balme Noire cave in a few minutes.

(8) At the cave, turn back to return to the previous junction.

(7) Continue straight on. You’ll come across some rather irregular blue markings. The path soon becomes a forest track, which joins the outbound route at the junction of the forest tracks.

(2) Turn left to retrace the outward route in the opposite direction and descend the Pas des Rages until you reach the car park (S/E).

Notes

On this route, the base maps are sometimes lacking in detail.
(2): there are two additional tracks that do not appear on the maps.
(3) and (4): the paths to take at this point do not appear on the IGN map, but they are clearly shown on the OpenStreetMap.
(6): Neither map shows a path here, but this is indeed where you end up when following the track.

Where the path runs alongside the cliff, it always maintains a safe distance from the edge. There are no difficult or vertiginous sections. However, the drop-off is not far away, so you must remain cautious if you approach the edge to enjoy the view.

At the start of the route, there is a farm with several Patou sheepdogs. They are sometimes in a pen right next to the path, separated by a small fence that isn’t particularly reassuring. But despite their aggressive appearance, they are well-trained and will leave you alone if you stay on the path. Be careful: if you value your fingers, leave them alone too.

Note: this route is based (with a slight variation) on a walk published on the Grenoble Montagne website.

Worth a visit

The climb up the Pas des Rages is lovely and takes you past the waterfall on the Rages stream.
There are lovely views of the gorges along the cliff-side path.
The Balme Noire cave: if there’s enough light, you can venture inside for about a hundred metres. After that, the passage narrows and is reserved for cavers.
The Bourne Gorges road (D531 from Villard-de-Lans to Pont-en-Royans) is one of the most beautiful in the Vercors.

A lovely walk with not much elevation gain, but with a steep climb up to the ‘Pas des Rages’ and to reach the cave – for which it’s worth having a good torch so you can venture a little further in, right up to the area accessible only by caving. We disturbed a few bats and saw some stalactites and stalagmites... And on these sweltering days, eating in the coolness of the cave entrance was a real treat!
We did the route in the opposite direction to the one indicated, which meant we could cover the few hundred metres on the open road (and therefore in the sun!) on the way down, so we didn’t get roasted!
The rest of the route was mostly through the forest, with lovely views over the Bourne Gorges, along good paths that weren’t very busy that day... We felt a world away from the crowds at Chamechaude or Lac du Crozet – it was lovely!

A challenging and technical hike in a varied environment. Unfortunately, we did most of the route in fog, which meant we couldn't see the gorges!
We'll have to do it again on a sunny day!

A beautiful hike with lovely views from the top of the cliffs.
The highlight of the show is a visit to a rather impressive cave, but be careful as the descent to get there is a little steep.
Otherwise, there are no real difficulties apart from the start of the hike, up to the Pas des Rages, where you climb the steepest part.
I used the app to follow the route, so I had no problems.

Overall, the route is good, but there are not enough signs indicating where to turn, and some sections (point 7) are difficult and require proper equipment (shoes, walking sticks).
Beautiful view, but for someone like me who is afraid of heights, it's quite difficult, although for others without this fear, it's easy.

Beautiful route above the Bourne Gorges. After visiting the Baume Noire cave, it is best to take the first path on the left marked with blue lines, which descends to the Valchevriere bridge, and hitchhike back to your car at the power station

A magnificent hike! There is a large car park at the hydroelectric power station, which is very convenient. The start isn't obvious; we couldn't find the beginning of the GRP trail, but we were able to identify it on the way back down. After crossing the Rages stream, the forest track turns left and climbs parallel to the stream (although it remains distant and below). The forest track then turns right. At this turn, continue for a few metres and you will find the path on the right, hidden by vegetation. The rest is easy to find. Alternatively, you can stay on the forest track, which joins this path further on. The descent between point 3 (on the way back) and point 7 is very steep. Good shoes and walking sticks are recommended.
Most of the route is sheltered by trees, which is very pleasant at this time of year.
In any case, many thanks for this hike!!!

Beautiful views from the top of the cliff (markers 3 and 4 on the map): /!\ caution with children /!\

Much of the route is shaded, making it ideal when the sun is beating down. I set off from the new car park at the Haute Bourne hydroelectric power station (the owner of the lodge told me it had just been built).
My GPS calculated 12.9 km, and I walked for 4 hours and 15 minutes (not counting breaks).
The start is quite tough (steep, winding climb).
Landmark 6, Haut Méaudret hamlet: I lost the trail here and cut through some undergrowth, but it wasn't very practical. I'm not sure what advice to give to stay on the trail (perhaps keep your eyes peeled)

A beautiful hike completed in four hours one afternoon in beautiful weather, with a clearly marked route. The return path through the forest is well marked with regular blue dots, contrary to what is written in the hike description (the markings have certainly been reinforced since it was written).
I didn't meet a single person on the 11 km route.
Magnificent views at the top of the gorges.

A very beautiful route. The panoramic views above the cliffs are simply spectacular.
The start (and therefore also the finish) is tough.
We did it the day after a night of rain and even started the hike in the rain, but that didn't make the trails any more dangerous.
The route is very reliable and allows you to make the right decisions. The description is accurate, with perhaps one small caveat just before point 6. There is no indication that you need to leave the path to climb a small trail before crossing a meadow (otherwise you have to walk a few hundred extra metres and pass through the hamlet of Meaudret).
The descent at point 3 is extremely steep but worth it, as the Balme Noire cave is spectacular.
Thank you for this wonderful suggestion.

Superb hike, particularly along the cliff edge above the Bourne Gorges, with magnificent views of the gorges and also of the Vercors peaks above Villard de Lans and Corrençon, still covered in snow at the beginning of April 2021. The trail is fairly well marked overall, but sometimes narrow and exposed on ledges along the cliff edge, so not suitable for children or people prone to vertigo. Quite busy for a hike in the Vercors.

A very pleasant walk when the weather isn't good enough to head for the peaks. The Pas des Rages pass, the walk along the cliff edge and the visit to the cave add great variety to this well-designed route.
The walls of the Balme Noire cave reveal a multitude of shiny little golden lines towards the back. Can anyone tell me what they are? Bacteria?

A superb hike with magnificent views of the eastern Vercors mountain range.
Obviously, this hike is not recommended in foggy weather: it is better to be able to see where you are putting your feet on the (superb) section where you walk along the cliff.
The descent between points 3 and 7 is difficult. It is very steep with loose gravel underfoot. It might be better to do the circular route between points 2 and 7, to see the cave, in the other direction. So, go from 7 to 3 uphill.
Of course, it goes without saying that you need to be very careful if you take children to the section above the cliff.

A superb walk with magnificent views. The only problem is that despite the GPX tracks, we lost the trail several times. This forced us to scramble over very slippery scree slopes.
The climb is shaded, so it can be done during the hottest hours of the day.
The section along the edge of the gorge is simply superb.

Hello
I did this route yesterday...you really need to study the car park carefully, it's very important. It's a very busy road, with motorbikes and cars, and lots of bends, so you have to make quick decisions. I recommend the electric factory, even if it says "no parking", there are no other options... and there are lots of parking spaces. The owners of the lodge made an exception and allowed us to park there, but we only had one car.
We didn't do the return trip from 7 to 2, as locals told us that the path was really not easy. On the other hand, the rest of the route is very beautiful, despite a few thrills at the edge of the cliff.
We didn't really see where to turn towards Méaudret, so we continued and followed the road...to return without any problems to Pas des Rages. It's a beautiful hike, but not recommended for people who are prone to vertigo.
