L'Étang Bleu

This high-altitude hike gives you an exact view of the high mountains of the Ariège and their perched ponds. This small pond in a peaceful setting has an immediate charm.
Moderator's warning as of 22/03/2021: Caution! in snowy conditions, very tricky passage; see reviews

Description of the walk

From Tarascon take the D618 to Surba in the direction of Col de Port, then to Rabat-les-Trois-Seigneurs on the D223. Pass La Freyte and follow the road to the car park.

(S/E) From the Pla du Ressec at 1022m, take the track for about a kilometre to reach a ford.

(1) You need to cross the Courbière stream on the left by the cemented ford (or by the wooden footbridge slightly higher up), don't be confused by the routes on the right that take you from this point, this will be the way back. To the east, on this forest road, you gradually enter a beautiful fir forest. After 400 metres, turn right onto a logging track.

(2) Leave the road and turn right onto this track, which runs west-south-west and becomes a footpath after a 10-minute walk. After two short hairpin bends, you enter the Bois du Debès du Ressec. The path runs alongside the Barataus stream.
From the orri (30m up on the jasse, 1273m), the path becomes steeper and winds its way through a beech forest. Later, as you follow the series of switchbacks, you will see the Rocher de l'Aigle on your left. Soon you ford the Barataus (1670m), and finally arrive at the Jasse de l'Étang Bleu (1h50) where you will find numerous ruins of shepherds' huts.
The climb continues due west to Étang Bleu.

(3) From l'Étang Bleu, the path climbs to the right over the small knoll overlooking the Rives and Tirou ponds at 1804m, where an aerial view awaits you. Take the Chemin du Cirque d'Embans and follow the ridge line (1822m) above Étang Long. After a few twists and turns to the west and fording the Embans torrent, the path descends steeply for around 300m (this is a particularly steep area, so take care with children).
You will then arrive at the Cirque d'Embans (see note below).

(4) The descent continues into the Bois du Cirier, through a beech forest. A series of small switchbacks will take you to the footbridge over the Courbière.

(5) Leaving the Cabane d'Embanels (1022m), turn right across the meadow to reach the forest road at the ford.

(1) Continue straight ahead on the road to reach the car park (S/E).

Notes

Note Cirque d'Embans: this is an ancient glacier of historic importance, as in the last century the people of the Ariège used to carry blocks of ice down on their backs to sell in the valley, and even as far away as Toulouse.

We did the route anti-clockwise, as recommended in a previous review. The climb from the Embanels hut is quite tough, but it's better to climb it than descend it, especially if it has rained recently!

Hike completed on a beautiful day, sunny, no wind, around 30°C.
The route was dry and not very slippery.
We did it in the opposite direction, following previous advice. And I think it's better that way.
There are no major difficulties in dry weather with good shoes, nor are there any dangerous or technical sections
However, there is a steep climb to get out of the small cirque, so you need to be in good physical condition.
Relatively few people at the blue lake, 15 at most, with a few swimmers.

Given the effort and time required for this hike, there are much more beautiful and wild mountain lakes in the Ariège. Such as the Garbet lake and the Blue Lake (the other blue lake) in a wilder and more mineral environment, where you will encounter fewer people.

Superb hike, everything is beautiful!
The work is finished, so you can now do the whole circuit. There are still a few tree trunks and dead branches, but it's clean.
I followed the advice and did the circuit in reverse. Of course, it's very steep, but it must be even more difficult going downhill. Good equipment recommended. It's still difficult, but not dangerous at this time of year.
Don't forget to turn around, it's beautiful on both sides and, contrary to what you might think from looking at the map, there are some very beautiful views in the wooded area between 2 and 3. The Cirque d'Embans is magnificent.
The circuit seems well known (so I noted "very busy"), but today it was very quiet. The rhododendrons were at the end of their flowering season.
Thanks to the Tourist Office.

Superb hike with varied landscapes, I recommend it!
We did a round trip via the cirque because there was forestry work on the other side (which, if I read the sign correctly, should be finished by mid-June).
Having done it both ways, I think it's much easier to climb up to the blue lake via the cirque, as the rocky, steep section at the top is a bit tricky on the way down! I therefore recommend doing the hike in the opposite direction to that suggested by Visorando (but make sure you wear good shoes).
Be careful to take the right path in this case: when you reach point 5, take the footbridge on the left to cross the river Otherwise, you'll find yourself climbing, climbing, climbing on a path that looks perfectly maintained... only to have to turn back once you reach the top, because the pond is on the other side of the valley (haha)!
In short, it's a great hike, so don't hesitate to give it a go!

We had to do the round trip via the cirque because the other side was closed for forestry work (indicated on the signs at the start of the loop).

The ascent via the cirque is steep but well signposted and fairly regular. The descent (via the same side) is a little tricky, but not dangerous, but you need to take your time.

A wonderful tour to do, with beautiful autumn colours and sunshine!
No snow in early November. Very little traffic (only two pairs of hikers).
Start at the cirque before the Etang Bleu (don't choose the "easiest" route as the slope is steep with lots of stones on the way down).
For the forest section, follow the tracks carefully - you can't stray off the path if you're careful.
I was on my own for this hike, so I didn't have any walking sticks, but I did wear suitable shoes.
A nice lunch break in front of the blue pond, an incredible panorama! (Make sure you bring a good woollen jacket, as it was a bit windy and starting to get chilly).
A loop with breaks completed in 5? hours at a moderate pace. Don't forget to set off early, as it gets dark earlier at this time of year
I recommend it!

We hiked in early autumn - no snow and changing weather with sunshine and passing clouds.
With 2 children (6 years old who walks quite well) and 4 years old (carried all the way in a hiking baby carrier). Above all, you have to do it in the opposite direction to the one indicated on the spot (and therefore not follow the "easier route", which seems illogical) and therefore start by the Cirque before the Etang - otherwise, the descent is too steep and dangerous, whereas in the upward direction, it's largely doable (if there's NO SNOW) if you take your time.
We had ba^tons and real hiking boots.
It was a wonderful hike, though, with the autumn colours and light. Only a few hikers we passed. AT THE TOP!

Magnificent tour to be done in dry weather only. I pushed on to the Col de la Couillaute, where the view is magnificent but there was already quite a bit of snow so I had to be careful. The descent into the Embans cirque is quite challenging and in places perilous, with loose stones and water running everywhere. Don't forget good boots!

This hike is best done outside the summer season, as it is very busy. There are plenty of watering holes, a very pleasant way to cool off.
A very decent climb from the start to the pond, but what a reward!
No chance of regretting it. There are several lakes to discover and you can continue on to the Pic des 3 Seigneurs (from 1800m to 2100m) ❤️
The Embans cirque is magnificent, but you'll need good hiking boots as the descent is steep and, above all, loose.

Very nice walk, very well signposted, but be careful on the wet, rocky descent - you need to be well shod.

A very nice walk! It's done in the direction indicated and is easy to follow. The climb is a little steep (almost 800 m) but not difficult and well worth it when you reach the pond. It was sunny and warm, so it was great to have a dip before the return journey. However, being a beginner, we found the descent to the cirque a little tricky. The views are magnificent though! At the end, we were attacked by a horde of giant mosquitoes, so beware.

It was a superb hike and a slightly apprehensive way of getting my (rusty) legs back in shape, but in the end it gave me a new lease of life so that I could set off again as soon as possible to tackle these beloved mountains! We really enjoyed doing the ascent in the direction indicated in the description, as it was steady, rolling and, above all, cool and shady on a fairly hot July day. Magic light in the beech forest! We saw the orri well camouflaged with moss. Not too many people at the pond, picnic and a swim (cool water but very affordable). Lots of flowers. Still delighted with the direction of the loop on the descent, where you always have to be very careful anyway. The tricky section is best negotiated with at least one stick (and hiking boots, of course!). And the view of the Embans cirque all the way down to the forest is a feast for the eyes. The markings are quite adequate and we came across an agent who was in the process of repainting and adding to them (especially between the Etang Bleu and the Etang Long, from where there are lots of little tracks outside the loop).

A very pretty and interesting circuit, but you need to be well shod as the climb through the undergrowth is tough, 800m of ascent. At the top there's a magnificent lake and the descent is rocky and technical, so you'll need poles.
