Around the Combe d'Orvaz

Hello,

I’m sorry to hear that you had to cut the walk short and hitch a lift back.
It’s best to do the walk in the direction indicated for two reasons:
- the route is clearer in the direction indicated,
- the path between points (2) and (3) runs along fairly steep slopes, and I would advise against tackling it in the downhill direction.

My last visit to this area was on 13/09/2025, and it is possible that forestry work has since taken place in the Combe de la Semine area, which has disrupted some access routes (to be checked).

Kind regards

A lovely walk.
Based on the directions, we decided to do the route in the opposite direction. We never managed to find the path leading back down to the hamlet of Orvaz. After walking a further 6 km, we reached a road and ended up hitchhiking. It’s possible that the spruce trees bearing the markings had been felled due to bark beetle infestation. In any case, the markings disappear abruptly in a section where it’s difficult to turn back.
It’s advisable to download detailed maps in advance (there’s no mobile signal at the bottom of the cirque) or to take an IGN map with you.

Hello,

That's it, I've done the left bank (last April) from the top, having parked at the mini car park where the path leading down to Combe Bandit leaves the D48a. I was able to get to the foot of the big waterfall. It's quite possible for a good hiker, and I found it even easier than the part of the path between the gorges and the Combe Bandit.
The Combe Bandit is always well marked in blue and there are plenty of fallen trees to go over and under or around. After making the round trip to the large Saut à l'Âne waterfall and also the lower waterfall, I continued along and down the gorges on the path but didn't go all the way to the bottom. So I still have to discover the lower part of the left bank.
But my aim was to get to the foot of the Grand Saut à l'Âne, and that's done: in the direction of the topo, in the long, steep straight that follows the end of the flat part that runs alongside the gorges, about halfway down, there's a small flat spot (rare in this area) on the left of the path. Head in this direction, and after a steady but safe descent of twenty metres or so, and after crossing some fallen trees, you come to a wider level where there are some large boulders, one of which is flat.
To get to the big waterfall, you have to cross these boulders and more or less find a path after them, then continue across keeping about the same altitude with the river quite far away, after 100m you cross a ridge (this is the level of the lower waterfall), then continue across for at least 200m and little by little, between the trees and a few rocks, the river comes closer as does the waterfall where you reach it without difficulty. The least obvious part is about 100m before the waterfall where the slope to be crossed with the river a little further away is a little steeper with a rock in the way, but nothing too serious, I went along the bottom of the rock. The fallen trees and small fir trees to cross at the end are sometimes more problematic.
It's quite easy to climb up and admire the waterfall on the cliff to the right (by looking at it).
On the way back, after crossing the slightly steep crossing section, you can easily get closer to the river by passing to the left of a large boulder, and you arrive at the top of the lower Saut à l'Âne waterfall (which is not on the maps).
You can also go to the foot of the waterfall (which I did, but with at least 60m more ascent) from the level where there are several boulders. A small river with lots of rocks flows down from the boulders to near the waterfall, but it's easier to go through the wood to the left. It's a little steep but easier to reach the waterfall just below the one you can see, and all that's left is to walk along the river, which you can see for a few metres, until you reach the waterfall. To really get to the foot of the waterfall, you have to negotiate a small, usually wet, step, which requires some care.

I've added photos of the fairly technical part of the gorges at Combe Bandit (between points 2 and 3).
There are occasional crossings of a couloir plunging into the not very visible gorges, including one (with beautiful cliffs on the right) where the leaves completely covered the tiny path. The steep slope ends in a not very reassuring gorge corridor on the left (photo attached).
Otherwise, the long, steep, straight slope separating the ridge above the gorges from the Saut à l'Âne rise is also partly difficult: fallen trees and a steep corridor that is a little slippery but not exposed.
There is also a key passage, the chimney that allows you to cross the sheer drop above the Grotte at point 3: with the leaves and the damp, you need to be careful because at the top, you overlook the sheer drop.
I spotted the path leading down to the upper Saut à l'Âne, but didn't go there. It is in fact below the young trees, which are a bit of a hindrance to getting into the real Combe Bandit meadow, where the wide path appears (or ends), crosses it and goes up to the D48a road. If the river crossing at Saut à l'Âne (above) poses a problem, this carriage road to P1032 above the Sémine waterfall (point 7) is longer but quieter.

Enjoy the hike.

Hello,

Thank you for your detailed review.
I think I have identified the locations you mention:
- i had the opportunity to walk the route between marker P1154 and the point (5) once, and it is indeed not very obvious
- i went down to the bottom of the Grande Cascade waterfall, but I couldn't find the path leading to the top that would allow me to walk back up the river as you did
- regarding access between the bottom of the upper Saut à l'Âne and its top (point (4)): some time ago, I spotted a not very obvious passage on the left bank (to be checked to see if it is still passable). I did it from the top and the access was more visible in that direction.
- for the return to Orvaz, the direction is not necessarily obvious after the spring, and it is important not to miss the orange markings, which are very helpful (see also my other track)

Best regards

Here I am again. This time, I went back, starting with the Roches d'Orvaz first, so in the opposite direction, hoping to then cross the Semine and finally discover this left bank trail (between points 2 and 4). But in the end, I only did a variation of the circular that I'll describe in detail, although I did make a little more progress towards these secret gorges and waterfalls.

So first, in this direction, the climb to the Roches d'Orvaz has two little pitfalls:
- the start of the hamlet of Orvaz: the meadow you enter has no path, so you wonder if you're in the right place. You have to head towards Les Roches and then you'll see a path branching off to the left, making a hairpin bend to pass an orientation table (photo I added).
- Passage at point 12: there is no (or no longer) sign to leave the wide path that crosses the combe and take the steep final path. Only a yellow mark on a small rock on the ground and a few pebbles. I noticed this at P1004 and turned back.
Then, along the pleasant rocks, although a decree asks you not to get too close to them, and indeed large crevasses are widening.
Then came the plateau forest with wide paths that were not always easy to follow, but generally to the right.
As for me, I wanted to cut across and discover the path that starts at P1154 in the part overlooking the gorges. There is indeed a cairn and the path leads steeply towards Orvaz, arriving at a viewpoint at the top of the rocks/cliffs overlooking the gorges. From here, the path leading to the Saut à l'Âne starts discreetly but is not obvious, and is narrow for a small ledge that requires caution.
Otherwise, the path towards Orvaz is more marked, which is why it remains on the detailed IGN map, whereas the one I am going to take is no longer there. So, once you have crossed the ledge, this is the part where the path is least obvious, but you must continue to cross under the upper rocks. Crossing a couloir requires caution (walking stick recommended), then you cross a small scree slope, then a small slab. After that, it is more marked and easier, and you eventually arrive at point 5, but the tree cuttings are a bit of a hindrance and have made the path connecting to the large flat area disappear.
Then descend to Saut de l'Âne (upper). Always go into the lower woods (SE then turn right SW, sometimes old yellow markings) to overlook the gorges from a ledge. On the left, the path is blocked by a fallen tree (go around it) to reach point 4, the top of the upper waterfall. But once again, the flow is not huge but sufficient to make it impossible to cross the Semine safely, both towards the waterfall and upstream towards a small meadow.
I then set off in search of the Grande Cascade, still on the right bank. I retrace my steps. Shortly after the fallen tree, you can see the top of the Grande Cascade. I continue along the cliff face and after less than 100 metres, it levels out and we can descend (photo) to the lower part, where there is a more or less visible path. This time I head left, heading back east, this time along the bottom of the rocky cliff face. A path across the cliff face is slightly visible. The large waterfall on the right is getting closer, but with a steep slope ending in a large cliff. When you reach the waterfall, the slope becomes difficult to cross. It is best to head towards the waterfall, which is quite close on the slope. It is steep, but with a walking stick it is manageable. You are now above the first cliff, but it is difficult to see the large waterfall, even when you are very close.
However, upstream, you can see the upper Saut à l'Âne in the distance. A large fallen tree upstream can be crossed using its roots, then after crossing other smaller trees, I was able to cross the Semine to easily reach the rocks at the foot of the upper waterfall (photos). But on the left bank, at first glance, there is no feasible climb to reach a path.
After flying my drone around to admire the large waterfall, I decided to return to point 5 given the time rather than go back down to inspect the right bank again (particularly the access at the bottom of the Grande Cascade). So I climbed back up the same path to P1154, with its slight difficulties at the end, to descend to Orvaz.
This last trail is fairly easy, with a few trees to climb over during the long traverse. You pass above the mini cirque of the Résurgence (which you can climb to the top of if you're careful), then cross a scree slope/couloir, before finally coming across several large trees where the path disappears. In fact, you are not far from the source on the map. So you have to head more towards the slope, which has become much gentler, and you can see reddish marks on the trees, which is the right landmark. You will finally follow the hollow of a rather dry mini river, heading straight towards Orvaz. You will arrive at a meadow with a well/spring, and a wide path branches off to the left, which will take you to the Orvaz wash house.

That's it, the next stage is the bottom of the Grande Cascade, still exploring the left bank. I've found that winter is much better for visibility and off-trail hiking for the waterfalls on this hike.

It's not easy to follow the route, but in the end you'll find your way! I can confirm that if you stay on the same bank from A to Z, you won't be able to reach the bottom, but you can access a few additional waterfalls, although the access points are exposed (be careful!).
Other than that, it's a beautiful hike, with a fairly steep incline but nothing impossible

Hello,

Well, while exploring online (via canyoning), I just realised that the highest waterfall in the Sémine is located above the one I found below (which I called the 'Saut à l'Âne inférieur' waterfall in my description). This means that there is another waterfall that is not on the Géoportail map.
In fact, this high waterfall, which is nearly 30 metres high according to canyoning experts (which you found yourself above, starting from point 3), would be almost at the location of the 'Saut à l'Âne' on the map (very slightly upstream according to the altitudes given) with a large cirque. And it is "my" waterfall, about 15 metres high, which I discovered off the trail and which is not on the map. It is a little further downstream from the 'main Saut à l'Âne', so to speak.
I have posted photos of the 'lower' and 'upper' Saut à l'Âne waterfalls. All that remains is to explore to find the 'main' Saut à l'Âne, probably via the left bank, or perhaps by following the first drop I crossed during my descent, which would take me above the lower Saut à l'Âne.

As for the waterfall downstream, the fourth from point 1, your explanation confirms that it is not easy to access. I have posted a photo of the narrow corridor that probably leads to this waterfall. It was from this point (the start of the corridor) that I was able to access the north slope, joining the path below Montelet despite the fallen trees.

I will probably return there in the coming weeks or months to hopefully see this 30-metre waterfall up close.

Hello,

Thank you for this detailed description and these beautiful photos. The waterfalls are stunning after the recent rains!

The area is not at all easy to navigate and you have to be very careful, especially if it is slippery (as you have seen). The slopes are steep and rockfalls can be a risk.
Like you, from the point (1), I had the opportunity to climb up the stream on the right-hand side on a path that is quite exposed to the void and where you have to be precise. From memory (my last visits were not recent), the large boulder to climb rings a bell: I remember it being one of the difficulties. I don't know if it's the same one you're referring to. I then continued on to reach a mini gorge between two large boulders where it's not possible to continue without getting wet (so it was almost a dead end).
From the Saut à l'Âne (point (3)), I didn't know the access you mentioned via the right bank. For my part, from the top of the waterfall on the left bank, I took a small, discreet path that required caution (especially on the descent) on a short section. Once at the bottom, I had "pushed on with the exploration" downwards (without difficulty) until I reached the overhang of another waterfall of considerable height, where access seemed very difficult to me. I didn't go any further.

Best regards

Hello,
I wanted to see these gorges with their many waterfalls, and after the good rains of the last few months, I set off from Orvaz on this long Ascension weekend
It started well because the first springs before point 1 already gave me two unmarked waterfalls: the one before P762, which flows over the path via a mini footbridge, and then the Résurgence, which I recommend getting close to because after an easy 30 metres, you can see the mini cirque with several waterfalls flowing out of it.
Then, when I reached point 1, the end of the markings, a yellow mark on the tree clearly indicated a U-turn, followed by a cross further on. What a shame. In fact, another fallen tree was blocking the path along the right bank of the river, and this path was now narrow and overhanging the river. Nothing to see anymore. The Sémine was quite full and I couldn't see the dotted path opposite or where to join it.
My goal being the waterfalls, I continue, carefully climbing over the tree, continuing on the right bank despite the slightly wet ground, which is sometimes slippery but not dangerous. After two passable trees, we saw the first waterfall on the map. The narrow path continued to cross a few steep metres, even a drop, above the river, up to the upper level of the waterfall. From there, we could see the second small waterfall (about 3 metres high) with its pool.
We continue across, but the height above the river increases, and as we see the third waterfall, a delicate crossing requires caution as the 'path' crosses a mini corridor (1 metre wide) plunging steeply into the river. Before the waterfall, you cross a steep, leafy gully to reach a rock just to the left of the nearby waterfall. For me, this is where I failed. The 'path' goes through here, but it is at least 2 metres high with unstable ground sloping steeply down to the foot of the waterfall. The rock has a step, but it is quite high and mossy. The real problem is that there is nothing solid or easy to hold on to with your hands.
I then tried to climb up the steep valley (fortunately with a good walking stick) to try to cross this rocky ridge, but it wasn't easy to get down the other side without a rope. I perhaps regret not having descended it, even if it was narrow at the point where I couldn't get across.
I therefore attempted to climb back up the valley, hoping to find a passage to reach the upper path that runs along the gorges below Montelet, but despite this journey, with impressive cliffs on the right and a long rocky ridge on the left (I attempted a steep ledge but the rest was still uncertain among the rocks), with stones that once started rolling down didn't stop, and no path in sight. Only two chamois came down the slope at full speed, causing several rocks to fall, which I avoided. I returned to the top of the Resurgence, which I could barely see, and was able to descend the slopes and ridge on its left, which were steep but less so and well wooded, phew.
A little disappointed, I returned two days later, starting from point 6: a small cairn on the wide forest path indicating the place to descend to the Sémine waterfall. The marked path is a little steep, but descends fairly easily to the river and then the waterfall.
Then, we take the wide path again and I confirm that, due to the felling of trees, the start of the path leading north to Montelet has disappeared. Instead, there is a rather steep path that climbs up to the last 't' of Montelet on the map in the direction of Montelet.
I spotted two cairns located before a forest car park, which are indeed at the location of the dotted line descending on the map. Descend to the left via a barely visible path, on a flat area of young trees, then turn right to approach the steep slopes of the gorges. You can still see a few yellow marks on the trees, but a tree blocks the way. You can get around it on the left and join the fairly easy path that descends upstream of the river and takes you to the top of the upper Saut à l'Âne. It's a large waterfall, but it's difficult to see the bottom of the gorges. You can also see the path opposite leading to Combe Bandit, but it's not easy to cross without getting your feet wet. A fallen tree upstream of the waterfall is also an obstacle.
Then I returned to the flat area to follow the steep slopes, still on the right bank, in order to find access to the lower Saut à l'Âne. After about 100m overlooking the cliffs on the left, you can find an accessible slope heading west, leaving a cliff on your left. After descending a moderate slope, you come to another ledge which, if you look carefully (still in the downstream direction of the river), has an easy ledge (trail) to descend into mossy boulders (good landmark). The slope here, although steep, is manageable, and there is sometimes a trail. As you descend, the ledges on the right again lead you upstream towards the river. The last 5 metres gave me pause for thought: there was no path upstream (towards the waterfall) and a slab to cross with a tree in the way to try to follow the river. This second solution was the right one despite the tree. We were able to walk along the right bank of the river, despite having to step over some rocks in the water, and after 30 metres we came to a cave on the left. We then walked along the walls between leaves and fallen trees, finally going around a tree to find ourselves at the foot of the lower Saut à l'Âne waterfall.
Back at the foot of the climb, leaving the river, I noticed that this was the start of a narrow gorge where you could see the beginning of a waterfall at the bottom, probably the last one to see, the one in the middle.
However, after walking along the cliffs, still on the right bank, for at least 200 metres, there is no obvious way to get down. Given the steepness and the time, I contented myself with taking out my drone, which was difficult to get out between the trees, to see this last waterfall, which has about three drops as it emerges from the narrow gorge.
End of the journey, a good climb that I had spotted.
Perhaps a tricky descent downstream from the last waterfall was feasible, but it was really very steep and I was starting to see the cliffs I had walked along two days earlier. But the waterfalls were flowing well and were very beautiful. Not a soul in sight on Ascension weekend!
So I didn't tackle the left bank of the gorges, maybe another time.

Good luck to everyone for this beautiful place, which might deserve a little development, as it's rare to find so many waterfalls along such a long stretch.

Hello.
Hike completed on Sunday, 23 May 2021.
The three of us set off from point 6 and finished at the two waterfalls.
The difficulty is clearly stated, so no complaints on that front; hikers set off knowing what to expect...
Thank you for this superb route, but it is indeed very difficult in zones 1 and 2. We had a lot of trouble because the trail is difficult to find. Fortunately, we had GPS guidance (which doesn't do everything!), but it is very complicated to reach the top of the rocky ridge; a lot of effort was required at this point.
This hike is demanding in places and requires you to stay on the trail in sections 1 and 2. To reach the "saut à l'âne" (donkey jump), you tend to follow the yellow markings, when you should actually keep to the left and follow the blue markings. We also made this mistake and had to turn back to find the right path.
The route in this direction on the rocky ridge around the cirque is superb and impressive (great height).
A good hike, but one that is still aimed at experienced walkers looking for thrills in the critical zone 1-2 with a complex ascent and tangles to overcome (especially after very wet weather)...
It's true that in the opposite direction, the paths to the two waterfalls, "Semine" and "Saut à l'Âne", are less easy to find, even though they are signposted at the start of the forest path. I film waterfalls in the Ain region, and sometimes you have to find the access points yourself...
Thank you for this adrenaline-filled journey!

Hello piccolopripri,

I also did the route from Roches d'Orvaz to Roche Fauconnière, passing through Combe d'Evuaz, either by road or by paths running almost parallel to it.

However, I haven't had the opportunity to do the route from Combe Bandit to La Grive, so I can't be of much help. From memory, I can say that the Combe Bandit section wasn't the most difficult.

I wish you a pleasant hike in advance.

Hello, I did the Roches d'Orvaz-Roche Fauconnière route a long time ago. Do you know if the path that starts just before Combe Bandit when coming from Orvaz and goes up towards La Grive (marked on the IGN map) is still passable?
Thank you for the information about the difficulties encountered in March-April. Not very encouraging!

Machine-translated

Hello,

I completed the route today in order to revalidate it as described. A few difficulties were noted:
- the watercourses had a good flow, making some fords difficult to cross,
- and many trees had fallen due to bad weather.
No significant forestry work was observed that could hinder progress.

In view of these facts, I currently recommend only making a return trip to Les Roches d'Orvaz (or even La Combe d'Evuaz) by taking the route in reverse to the description.

Machine-translated

For my part, additions have been made to the description (in particular, raising awareness of the preference for hiking in the direction indicated).

Taking a step back, it seems a shame that access to the Saut de l'Âne has not been promoted for some time (there is only a signpost (which is a bit old) pointing towards the Combe d'Evuaz farm).
In addition, I recommend reading a short article in the Journal du Progrès newspaper (read here).

NB: I also suggest an alternative, slightly easier route (avoiding the Saut de l'Âne); read it here.

Machine-translated

Hello Xavier,

I am very sorry that this hike was such a "nightmare" for you.

I can confirm that the route in the opposite direction is much less straightforward, particularly the access to the Saut de l'Ane, due to forestry work (still evident last autumn).

I wish your friend a very speedy recovery.
