Lac des Bouillouses, Estany de la Pradella, Estany Negre

A very beautiful snowshoe hike at an altitude of 2,000 metres.
It can certainly be done in summer. The only issue is the mandatory lower car park. The shuttle buses operating during this period can stop at this car park.
The recorded and suggested winter route does not correspond exactly to the summer route shown on the various base maps.

Description of the walk

Head to the Pla dels Avellans car park. This car park is accessible in winter once the snow has been cleared from the restricted road.

(S) Head north-west along the snow-covered road. After 250 m, take the path on the right into the woods and climb north-west. You’ll soon rejoin the road at a left-hand bend, but continue climbing through the woods, still heading north-west. Rejoin the snow-covered road and follow it now (as to the right is the mountain and to the left is the descent towards the river and the penstock). Follow this snow-covered road, cutting across all the bends by following the telephone poles.

(1) At around 1,890 m, it becomes impossible to cut across; you must then simply follow this snow-covered road. Look down over the torrent and, to the left in the distance, the penstock descending from Les Bouillouses. Reach a large left-hand bend at around 1,990 m (at this bend, a sign on the right indicates the direction of L’Estany d’Aude). Continue along the road heading south-west. You will reach a large bend to the right. The road then turns north-west.

(2) At the next left-hand bend, leave this road and head up to the right into the forest. This path overlooks and runs alongside the road.

(3) After 500 m, you arrive above the chalets and accommodation at Les Bouillouses. Climb up to the dam and cross it. You are now at an altitude of 2,000 m. You can take a well-deserved rest with a snack whilst enjoying this stunning view.

(4) At the end of the dam, head left, due south, with the Roc de La Calma chairlift in your sights.

(5) After 1,600 m, take a wide curve to climb above the Estany de La Pradella. Descend towards the lake by turning right and arrive at a shelter.

(6) Yellow markings are present. Take care to go round the lake on the right, keeping well clear of the frozen and snow-covered banks. Continue eastwards for 400 m from the shelter and leave the red and whiteGR®®10markings.

(7) Head left, continuing to follow the edge of the lake.

(8) Reach Estany Negre and go round this pond on the right, staying as close as possible to the forest. At the end of the pond, climb a small rise and descend into a steep gully for 30 m. Follow the stream on the right bank for about 150 m

(9) Cross it (heading due north). Then continue eastwards. Use the few yellow markings on the trees for guidance. From the point where you cross the stream, the path descends steeply through the valleys.

(10) When you reach the torrent (La Têt: which is actually a river), turn right, following a fence that runs alongside La Têt. Cross the Ruisseau de la Pradeille, which flows from Estany Negre, and continue following this fence. Keep following La Têt until you reach a mountain pasture (La Muntanya) at the foot of a chairlift.

(11) Take the bridge on the left which crosses the Têt and leads you back to the Pla dels Avellans car park.

Notes

At Les Bouillouses there is usually a hut and the sleeping quarters of the former CAF refuge. A water source is available near this refuge.
This is a winter hike; you will therefore need warm clothing, a windbreaker, spare socks, gloves, sunglasses, sun cream and a hat.
You’ll also need: a map, a compass, a route map for this hike, a flask of hot drink and a snack.
Please note that not all mobile phone networks have coverage in this area.

Worth a visit

Mont-Louis is a fortified town well worth a visit. There is the solar oven, the Citadel and the Train Jaune.
Font-Romeu is also nearby.
But please note that in winter, not everything is necessarily open.

A superb snowshoe hike that alternates between covered and open sections. No particular difficulties except at point 2 when leaving the road and at point 5 when climbing above Estany de La Pradella, where the snow cover prevented us from finding the trail. After a few adventurous detours, everything fell into place thanks to the app and GPS.

Thank you for sharing this, we had a great time.

A very pleasant hike in good weather.
There was a slight difficulty when trying to go around Lake Negre, where we had to climb up into the forest and descend into a very steep valley. There were no signposts at this point, so the GPS app came in very handy.

Great hike, very easy to follow, frozen lakes and snow-capped peaks are magnificent. Quite a few hikers, so I think it's a very popular hike in summer. No difficulty.

too many people are not keeping their dogs on a leash in a grazing area and are completely ignoring the regulations of the Bouillouses classified site...

Clearly the most beautiful snowshoe hike in the area.
The lakes are superb and, if the frost allows, you can go right to the centre of the small lakes (Estany de la Pradella and Estany Negre). Finding yourself alone in the middle of the lake with only the sound of the wind, no one else for miles around and these absolutely sublime landscapes is an experience not to be missed!
It's quite a physical hike with winds of 100 km/h on that day!
No matter, the feast for the eyes always wins out.

Great for summer.
I would like to point out a difficulty at point (8) "l'Estany Negre". I couldn't easily get around the lake on the right. There is no passage (landslide?) between the lake and the small rocky barrier unless you climb. I went around by passing to the right of the barrier, but there wasn't really a path, and it was difficult going... and even dangerous in one place. I was able to get back to point 9 after struggling a bit. I've included a photo of my route.
So, be careful.

a beautiful hike. To start, simply cross the dam, which offers a lovely photo spot with a mirror effect on the lake and the mountains in the background. The route is fairly easy and quite busy. Discovering the different lakes along the way is enjoyable and adds to the hike. The rocky mountain landscape is magnificent. To get to the start, at certain times and on weekends, you have to take a shuttle bus (for a fee) because the access road is closed by a barrier. This beautiful walk is a victim of its own success, so to avoid chaos in the car park, this shuttle service has been set up.

the snow-covered path and the landscape were beautiful, not very busy, and we didn't complete the entire loop. The walk is easily accessible.

A beautiful hike, the short loop of the 9 lakes starting from Lac des Bouillouses, taking 3 hours. No difficulties except shortly after the start where you have to climb some rocks, but it's not long. After that, it's an easy, safe trail with beautiful lakes surrounded by magnificent peaks, including the highest in the Eastern Pyrenees, Carlit (2,921 m). The trail is well marked with yellow signs and information boards. It was quite busy, even though it was September.
