Cirque de Cagateille and Étang de la Hillette

This hike, which presents no difficulty until you reach the foot of the Cirque de Cagateille, will make you sweat to reach the Étang de la Hillette.
But it's well worth the effort to discover this little Pyrenean fjord!

Description of the walk

Park in the car park at the end of the D38 road from Ustou.

(S/E) Take the path, which is the GRT59, on the left, then after a right-hand bend, climb gently along the ledge in the forest. Reach the first landmark on the climb, the footbridge at an altitude of 1158m.

(1) Continue straight ahead and you will soon reach the right bank of the Ruisseau des Cors stream. Reach the stream at the footbridge at an altitude of 1161m.

(2) Cross it to discover the Cirque de Cagateille.
Continue left towards the forest. Follow the left bank of the Turguilla stream.
It is when you enter the forest that things start to get serious. The slope becomes steeper and there are a series of hairpin bends. After a few steps, you will reach an intersection.

(3) Continue to the right into the forest, still on the GR®. When you leave the forest, the slope is very steep and your destination is still invisible. Reach the foot of a rocky outcrop. Handrails help you cross it without too much difficulty. You will come to an intersection before the Étang de la Hillette.

(4) Descend on the right down a passage a few metres high using the handrail, leaving theGR® trail on the left (put away your walking sticks if you have them, as they are of no use on this section).
Then follow the path on the left above the Hillette stream to reach the pond's spillway.
Continue along the left side of the pond.

(5) Pass the hut and continue along the grassy tracks to go around the pond, passing over some slightly slippery rock faces (be careful, it can be slippery).
Then cross the peninsula and the small arm of the pond via a ford to reach a marked trail above.
Turn right to return to the ascent path, climb back up the tricky passage you descended on the way down, then
descend the passage you climbed on the way up.

(4) Return via the same route as on the way up to reach the car park (S/E).

Difficult route starting from the Cirque de Cagateille
The last descent before the impressive Hillette lake
On the descent out of the forest, we came across three izards taking a break (a rare sight), which are usually rather shy. A wonderful memory.

It took us 5½ hours in total. The climb up through the forest is tough but doable if you're fit. Once you come out of the woods, things get tricky: it was very windy and there was still quite a lot of snow. This made the ladders and ropes quite dangerous. The lake is still almost completely frozen over.
It's a very beautiful hike, but the guidebook doesn't lie: make sure you're in really good shape before venturing out!

a magnificent hike reserved for experienced hikers, particularly in the section after the cirque, with lots of scree, steep slopes and areas equipped with chains to facilitate the somewhat perilous passage

A very pleasant and beautiful hike.
We saw some beautiful ibex.
A slight reservation about the arrival at the lake, which is quite technical, so be careful if you have children or dogs that are not used to climbing

The circuit can become very difficult after rain.
The steps under the clear wires need to be reinforced, otherwise they are useless.
On the other hand, the ibexes added a special attraction to this hike.
Given the slight drop in water level, the large peninsula can be used to cross Lake Hillette.

Easy hike to the Cirque de Cagateille, but then difficult, only suitable for experienced and athletic hikers. You must be careful to follow the trail. There are some tricky sections to navigate and the estimated time is underestimated. Beautiful setting at the lake, but you have to work for it.

Trip completed yesterday, Friday 28 April. Great hike with very varied terrain and scenery. The climb up to the cirque is very easy. Then it gets more difficult: it climbs steeply through the forest, and there are some slightly technical sections, as previous hikers have mentioned. The highlight is the famous "delicate passage" 5 minutes from the finish. I completed the climb in just under 3 hours, taking the time to take photos of the landscape and the first flowers.
The lake is very beautiful, especially if you walk around it, or at least part of it.
The icing on the cake: we encountered two ibexes!
The descent is a little technical, but it's a really nice hike!

An interesting route, unfortunately with strong winds as soon as you leave the forest.
Lovely views as soon as you leave the forest.

Occasional hikers, move along!
We are two forty-somethings, admittedly not particularly athletic, but in good health.
We completed this circular in 11 hours instead of the advertised 6 hours!
The route is indeed very difficult: there are almost no flat sections, not even gentle slopes, but slippery slabs, rock scree... and to top it all off, several sections with snow!
We followed in the footsteps of previous hikers, but even so it was dangerous, with several slips and falls, fortunately without serious consequences.
We didn't meet anyone between the Alet dam and the car park except for... a wildlife photographer who was watching for bears!
Fortunately, we didn't encounter any...
In short, this is a hike for experienced and cautious hikers!

A very green hike: the Cirque de Cagateille with its flowering meadows, torrent and groves, followed by the climb to the Hillette lake through a magnificent mossy forest. The hike ends in the summer pastures, paved with large granite boulders worn smooth by erosion. The tricky descent to the lake may be problematic for those who suffer from vertigo. For others, it's no problem, and the chain fixed to the rock face makes things easier. This is the only part of the hike that can be described as "very difficult".
Minor problems encountered:
- the path is poorly defined in the forest. As a result, when following the cairns, you tend to go straight ahead and climb quite steeply
- in the mountain pastures, the granite can be slippery or, at the very least, less grippy than one might hope
- i wanted to go around La Hillette in an anti-clockwise direction, and even with the GPS track, I could never find a way through (in fact, the GPX track makes us walk on water. For those who have faith, perhaps!...)
Pressed for time, I didn't push on to Lake Alet. It was a good decision, as the clouds descended below 2,000 metres just after I turned back.
I'll come back to do the full circular later.

The arrival in the Cirque de Cagateille with its numerous waterfalls is as beautiful as ever. The climb through the forest is steep, and the path is difficult to see in places, so follow the markings and cairns carefully. Once out of the forest, you'll walk over stone slabs and enjoy beautiful views (of the valley and peaks). There is a steep section just before you reach the lake, but chains are provided to help you. This is a beautiful hike that you'll want to do again, with a circular route via the Alate pond.

Magnificent hike, very steep climb to the Hilette lake.
You can make a circular loop by continuing on to the Alete lake (following the path from La Hilette) and then descending directly back to the car park. This adds an extra three hours from the Hilette lake, but it's a superb circular loop and avoids the descent, which is as steep as the climb. The path is quite popular for camping.
