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.

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.

What a brilliant circular loop!

The scenery is magnificent in September; there were about fifteen people at the lake, and you come across walkers roughly every 15 to 20 minutes at this time of year.

Try not to set off too late, as the car park fills up quickly. At 9 am there were still spaces left, but by 3 pm it was like ‘the underground at rush hour’; it has to be said that the weather was particularly pleasant, which attracted lots of families for a picnic down by the river.

The ascent is fairly steady, despite a short section that’s a bit steeper over about 300 metres of elevation gain. The descent is actually quite steep in places. Towards the end, you walk almost 3 km on a slight incline. Best avoided in wet weather. There’s about 50 metres of descent on dirt that quickly turns to mud.
The advantage of this route is that you’re in the shade for the climb, whilst a good part of the descent is in the sun. The people I passed on their way up were very exposed to the sun.

A lovely walk – thanks for the information and the route map!
We did the walk in the direction indicated, which is the ‘easiest’ route (as shown on the first sign).
We set off early, so there were only two or three cars in the car park and we didn’t come across anyone until we reached the pond.
On the way back, however, there were quite a few people heading up.
The track wasn’t exactly on the path (recorded using a Garmin watch), but we had no trouble finding our way (yellow markings). It took us 5 hours 40 minutes from setting off to getting back to the car, taking our time and spending over half an hour at the pond to eat and enjoy the scenery...
Indeed, on the way back, the car park was full and quite a few families had come to spend the day a little further up, along the stream.
There was also a van selling drinks.

This walk was done in the opposite direction, but it can just as easily be done in the ‘normal’ direction, which I’d rate as ‘moderate’ in terms of difficulty
The path is very easy to follow, and you can enjoy the beauty of the surroundings and the blueberries for those who like them.
The pond is a lovely spot for a picnic.
On our return, the car park was full; there was a ‘La Fringale’ food van where you could grab a bite to eat or have a drink.
I’d recommend it.

An absolutely BRILLIANT hike! The scenery is stunning and varied! We did the route in reverse to avoid the steepest descent, and it was perfect! At this time of year, there’s no snow on the trail, but there are some beautiful glaciers that make the landscape truly magnificent! It was absolutely brilliant!

First of all, thank you for the description and the GPS track. I did the hike in May in lovely weather. I thought the scenery and the views were superb.
I took the route in the opposite direction, as suggested by other hikers, and I think that’s the best option as it avoids a very steep and slippery descent through the woods.
The only difficulty was finding the path at point 4 (exiting the forest and entering the cirque). I only saw one yellow marker and then nothing else, and I couldn’t make out a path. I looked for a way through by following the direction I needed to go, and it was a bit of a struggle.
In any case, I thoroughly enjoyed myself....

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!
