Lake Bouillouses, Estany de la Pradella, Estany Negre

This is a beautiful snowshoe hike at an altitude of 2,000 metres.
It can also be done in summer. The only problem is the mandatory parking area, which is lower down. The shuttle buses operating during this period may stop at this car park.

Description of the walk

Head to the Pla dels Avellans car park. This car park is accessible in winter after the road has been cleared of snow.

(S) Head north-west along the snow-covered road. After 250 m, turn right into the woods and climb north-west. You will soon rejoin the road in a left-hand bend, but continue climbing through the woods, still heading north-west. You will rejoin the snow-covered road, which you now follow (as there is a mountain on your right and a descent towards the river and a penstock on your left). Follow this snow-covered road and cut across all the bends, following the telephone poles.

(1) At around 1,890 m, it becomes impossible to cut across; simply follow this snow-covered road. You will be overlooking the torrent and, in the distance on the left, the penstock descending from Les Bouillouses. You will come to a large bend to the left at around 1,990 m (in this bend, a sign on the right indicates the direction of the Estany d'Aude). Continue along the south-west road. You will come to a large bend to the right. The road resumes its north-west direction.

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

(3) After 500 m, you will 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. Take a well-deserved rest with a snack in front of this beautiful landscape.

(4) At the end of the dam, turn left, heading south with the Roc de La Calma chairlift in sight.

(5) After 1,600 metres, take a wide curve to climb above the Estany de La Pradella.

Descend towards this lake, turning right, and you will arrive at a shelter.

(6). There are yellow markings at the shelter. Take care to go around the lake on the right, staying away from the frozen and snow-covered banks. Continue east for 400 m from the shelter and leave the red and whiteGR®10trail.

(7) Turn left, continuing to follow the edge of the pond.

(8) Arrive at the Estany Negre and go around this pond on the right, staying as close to the forest as possible.

(9) At the end of the pond, climb a small step and descend into a steep valley for 30 m. Follow the stream on the right bank for about 150 m and cross it (due north).
After crossing the stream, continue eastwards. Use the few yellow markings on the trees to help you. From the stream crossing, the path descends steeply into gullies.

(10) When you reach the torrent (La Têt, which is actually a river), turn right and follow a fence that runs alongside the Têt. Cross a stream (which comes from Estany Negre) and continue following this fence. Continue following the Têt until you reach a mountain pasture (La Muntanya) at the foot of a chairlift.

(11) Take the bridge on the left over the Têt, which will take you back to the Pla dels Avellans car park.

Notes

At Les Bouillouses, there is usually a hut and the sleeping area of the former CAF refuge. There is a water source near the refuge.
This is a winter hike, so you will need warm clothing, a windbreaker, spare socks, gloves, sunglasses, sunscreen and a hat.
In addition, you will need a map, compass, route map, thermos flask with hot drink and a snack.
A smartphone with the route saved on it may also be useful.
Please note that not all mobile phone operators have coverage in this area.

Worth a visit

Mont-Louis is a fortified town that is open to visitors. There is a solar oven, a citadel and the Yellow Train.
Font-Romeu is also nearby.
However, please note that not everything is open in winter.

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.

Magnificent landscapes! As for the shuttle bus, it is only mandatory between 7 a.m. and 7 p.m. You can also reach Les Bouillouses from Pla de Barrès via a lovely 10 km hike.
