Description of the walk

Start at the first bend on the right from Aulus-les-Bains towards the Col de Latrape via the D8f.

(S/E) Take the track marked with a sign for Cascade d'Ars. The path climbs gently under the forest canopy.

(1) Continue straight ahead, leaving the path that climbs towards the Fouillet waterfall on your right.

Red and white markings for theGR®10

(2) Follow theGR® 10 coming from the left. The track then becomes a well-marked, easy path.

(3) Cross the Ars river on the Pont d'Artigous bridge. The path climbs through the forest with a few hairpin bends and the view opens up onto the Cascade d'Ars waterfall. It is possible to reach the foot of the widest part of the waterfall by leaving the GR® path.
The well-marked trail climbs steeply with a few switchbacks.

(4) At the waterfall viewpoint, the trail levels out and descends to a flat area where the Ars River meanders.

(5) Continue a few metres to the next intersection.

Yellow markings

(6) Leave theGR® 10 and follow a small path marked in yellow to the left. Go up the right bank of the Ars river, passing above the Étang de Cabadas.

(7) Continue following the sometimes discreet markings.

(8) At La Pitrade, cross the Ars river on a metal footbridge located a few metres from the Étang de las Touetos spillway. The trail is still marked in yellow and continues south-west.

(9) Cross a small stream a few metres downstream from the Hille de l'Étang. The trail crosses a few rocky outcrops before approaching the pond. Pass under a rocky outcrop by walking on the boulders in the pond.

No markings

(10) At the intersection towards the Orri du Turon d'Ars, take the path on the left towards the Ars river, which you cross via a footbridge, and pass close to a hut.
The path initially runs along the right bank of the Ars river before crossing it again to reach the left bank. Arrive at the Étang de la Hille de la Lauze.

(11) Return via the same route to the bend in the road at Col de Latrape (S/E).

Very beautiful hike. Please note: the path consists largely of rocks and may not be suitable for people who are not used to hiking. I would recommend wearing high walking boots for older people. The young teenagers we met had no problems.

Very beautiful hike. Relatively easy to reach the waterfall, with a few challenging climbs. Magnificent scenery and dreamlike vegetation once you reach the top of the waterfall. Busy until you reach the waterfall, then quieter.

Demanding as indicated. Very busy at the start towards the waterfall, then less and less so. The last section, from the yellow markings onwards, is extremely wild, with a path that is rarely used and requires a bit of searching through the vegetation, but the markings are there.
Completed in August, no problems with the river.
A very good discovery.
It's a round trip, the ratio is about 1000D+/7.5 km: it's a climb.

A magnificent hike. However, it is far from easy, even at the beginning up to the waterfall, as indicated on the information sheet.
We encountered quite a few people who were struggling.

A beautiful hike, but a little difficult to get to the pond at Hille de la Lauze.
At the pond hill crossing, we had to choose between getting our shoes wet or taking them off. We took them off on the way there (the water is FREEZING in April ^^), and got them wet on the way back!
Shortly before reaching the last pond, a footbridge is no longer in place, making it difficult to move forward and cross the stream, which flows strongly at this point. We jumped, but I don't recommend it.
We returned via this hike: https://www.visorando.com/randonnee-casc... This makes for a 18 km circular loop with 1,100 m of elevation gain, completed in 8 hours (including breaks).
The weather was a bit grey with sunny spells that revealed some wonderful colours.
We saw eight people up to the waterfall, then no one else except ibex.
A beautiful hike!

After the Ars waterfall, it's a hiker's dream... but shhh, don't say it too loudly! Hike done on 30 October in almost warm weather with rhododendrons in bloom!!! If you're feeling brave (it's a long hike), this route is for you, all the way to the Orris du Turon d'Ars, well marked in yellow.

Not too crowded, three or four groups of people at the foot of the Ars waterfall, but bear in mind, it was a weekday in May!

We did this hike up to point 6, the top of the waterfall (time constraints forced us to turn back), and it is quite passable. Up to the foot of the waterfall, there is no snow and lots of water. You even cross small streams, but it's not difficult.
On the way up, however, there was still some icy snow, which was very slippery, and the rocks were also slippery, so you have to be careful. Some sections are like ice rinks, but the path is perfectly passable. And the view from the top is well worth the effort.
We will return to finish the last third!

A magnificent hike, never done in winter before. Few people, therefore. The world of Narnia without the lion (and without bears, they hibernate...). Magical! No problems until the viewpoint: the snow made the climb a little longer, but the path remained perfectly passable and the markers were clearly visible. However, there was a little ice on the last few metres before the viewpoint overlooking the waterfall, so I didn't dare attempt the last section (waterfall-footbridge) without crampons. I did the same hike again on 30 December with crampons, and this time I needed snowshoes for the last third of the viewpoint-footbridge section: damn!

Very nice outing. Lots of people up to the waterfall, which is magnificent. Much fewer people further on towards the lakes. Very good path up to the waterfall, steeper after that but well signposted.

Nice walk, information OK. Starting from the trail at the Aulus exit at the "Col d'Agnes" sign is much more pleasant (stone walls, rivers, old barns, etc.) than starting from the car park on the indicated pass road.
