Plan de Baix, Gorges de la Gervanne, Cascade de la Druise, Croix du Vellan

This is a very beautiful hike, but should only be undertaken in very good weather. The first part follows the course of the Gervanne river, crossing numerous fords and wading through water, until you reach the magnificent Druise waterfall. The second part leads, via theGR®9, to the plateau and the Croix de Vellan overlooking the small village of Plan de Baix, where a 360° view allows you to admire some of the peaks of the Vercors and Baronnies.

Description of the walk

(S/E) From the compulsory car park at Plan de Baix, go back up to the junction with the D70C, turn right twice, and follow theGR®9marked R and B, a small road descending through the hamlet of Chabas and to the church. Cross the RD70 and continue straight ahead until you reach a crossroads, one of the paths leading to the church.

(1) Leave theGR®, turn 90° onto a small road markedGRP®, giving way to a path on the right that winds down to the bottom of the Gervanne valley. Stay on this well-marked path, ignoring the various other paths that branch off.

(2) Reach the Bâtie mast and continue towards Les Deux-Eaux on the right. Pass in front of a ruin and continue along the path leading to the Gervanne riverbed.
Please note: the IGN map does not show the entire length of this path, which nevertheless descends to the Deux Eaux mast and the Gervanne river.

(3) At the Deux-Eaux mast, the markings almost disappear, but it is easy to follow the river. Turn left and walk up the right bank of the Gervanne. Very quickly, you will have to cross several successive fords to get from one bank to the other to reach the Cascade de la Druise waterfall.

(4) Shortly before the waterfall, you will reach a fork in the path near a ruin. Stay on the left-hand path, following the stream to make a round trip to the waterfall.

(5) Then retrace your steps to the junction near the ruins.
Go up to the left until you reach the road, which you follow to the left towards Moulin de la Pipe.
At the next two junctions, continue straight ahead on the RD578A to reach the Moulin de la Pipe inn.

(6) Cross the bridge over the Gervanne and then follow the RD578 to the right. You will reach the Baume Noire mast.

(7) Take the path climbing to the left, towards Ruines du Chaffal and Le Grand Crot.

(8) At the next junction, Grand Crot mast: follow the path uphill to the left, towards Le Chaffal, La Côte and Plan de Baix. Stay on this marked path until you reach a forest track.

(9) Côte signpost. Turn left towards Vellan and Plan de Baix. Follow this ridge trail, markedGR®9, heading south-southwest, ignoring the various other paths and trails until you reach a tarmac road. Follow it for a few metres until you see a hairpin bend.

(10) Reach the path leading to and from the Croix du Vellan on the left.

(11) Return to the road and continue left until you reach the hairpin bend, where you take a paved slanting street down to the left towards Plan de Baix.

(12) After passing between two cliffs, you will reach a fork in the path, Mât du Dessous du Vellan (offering two options for returning to Plan de Baix). Follow the path on the left, passing below the cliffs, then further on, between houses.

(13) Join the road, follow it to the right, pass the hamlet of Vialaret, then a little further down, the hamlet of Les Perriers. Continue straight ahead until you reach the D70, then take the road opposite leading to the car park (S/E).

Notes

This is more of a summer hike, best undertaken on a sunny day in very good weather: depending on the water level, some fords can be crossed easily, but others require you to take off your shoes to cross through the water.
What is a very pleasant and enjoyable hike could quickly turn into a nightmare in adverse weather conditions.
To save time: if possible, bring a second pair of shoes that can go in the water (an old pair of trainers or water sandals), put them on near the stream and keep them on until you reach the waterfall.

From (3) to (4) on this section, there are livestock farms, so you must be particularly careful not to leave any rubbish behind and to close any gates you find.

We did not complete the route because the number of people slowed down our progress. We cut the hike short at the Moulin de la Pipe bridge.

Beautiful route. When descending towards Gervanne, be sure to leave the GRP at number 2 and take the path on the left. The GRP sign is a little further on. Disappointing return: several kilometres of track, even though the view at the Veillan cross is magnificent.

Hello,

bring two pairs of shoes if you can, as there are numerous fords (30 cm of water) in the beautiful, wild Gervanne River. After rain, the route may be impassable, so check the water level before setting off. The Druise waterfall is magnificent, but in hot weather the climb to point 8, although in the shade, is very long, so bring plenty of water.

A very beautiful hike that we have done twice (impossible to do if the flow of the Gervanne is too high. Example: Hike possible with a flow of 0.6 m3/s, water height 30-40 cm and weak current, impossible on 19/05/24 with a flow of 2m3/s) Visit this website to check the flow rate : https://hydro.eaufrance.fr, then click on the blue dot on the map for the Gervanne at Beaufort/Gervanne.

Wonderful hike with lots of points of interest. The view from the Vellan cross is breathtaking... Waterfalls, swimming in the opalescent pools of the Gervanne river. Best done in spring for the flowers and the scent of broom...

the route was completed during the rainy season, so there was a significant amount of water in the Druise. It is unfortunate that there were no signs indicating that the crossing was impossible, as there is no footbridge

A hike that crosses varied landscapes, very pleasant in the first part (up to point 8), less so in the second (forest track).
You need to pay close attention to the route, particularly during the descent towards La Gervanne at point 2, so as not to miss the path that turns sharply to the right. Similarly, the path that climbs up through the forest at point 6 is not very visible: it is on the other side of the road, opposite the "Mât de Beaume Noire" hiking sign. At this point, you can make a return trip by continuing along the road for about 100 metres to see the La Pissoire waterfall. The GPS track is very useful.
Be careful in May when crossing La Gervanne (around 16 times) following the rains that have greatly increased the flow of the river: the riverbed is wide and the current is very strong, so walking sticks are necessary to avoid falling; special footwear is required, including to reach the foot of the waterfall, which is magnificent.
It is possible to admire the waterfall from above when climbing the path by leaving it on the left about halfway along, at a large right-hand bend (marked by a cairn): the path and access to the waterfall are not secure (avoid with children or people who are prone to vertigo).
In short, this is a very beautiful walk, but not suitable for children after a period of rain.
With the view from the top of the waterfall and a visit to La Pissoire, this is a 21 km hike with a little over 900 metres of elevation gain.

A very pleasant route, very shady, and the fords are very refreshing and fun.
A beautiful hike.

Hello
A very beautiful and original hike, with all these passages through the Gervanne. Even though the water was cold, it was a wonderful experience.
The waterfall is also worth seeing! Please read the signs carefully and do not walk in the water to preserve this beautiful site.
The next climb is steep and very long, a good warm-up.
A very beautiful hike.
Done in a group of about fifteen people

Hello, it's a beautiful hike, but it's true that there are no markings along the Gervanne. It's a shame because there are lots of little paths. If I do it again, I'll start from La Baume Noire so we can do the climb in the cool of the morning

A wonderful discovery, welcome at the end of summer.
Due to time constraints, only points 1 to 8 were covered (one car at the start, one car at the Col de Bacchus). Approximately 11km, 720m elevation gain and 450m elevation loss.
Still a lot of water (up to knee height in places) in the Gervanne for this time of year (but not hindering progress along the route). The Gorges section remains cool, shaded and uncrowded (however, there are a lot of people around the waterfall).
Thanks to the author!

A very pleasant and enjoyable hike in its first part, up to the Druise waterfalls.
Follow the advice to bring a pair of shoes for crossing the fords; we counted up to 16 to cross (sometimes with water up to our knees). In between, the terrain is flat, which saves time
