Lac de Trécolpas and return via the Refuge de la Cougourde

This is a fine route with the beautiful Lac de Trécolpas at the foot of the Pas des Ladres.

Please note that following storm Alex, the start of the hike on the right bank is no longer possible and must therefore be made on the left bank.

Description of the walk

Take the Vallée de la Vésubie to Saint-Martin-Vésubie, then head towards Le Boréon and finally La Vacherie du Boréon. Park in the car park.

(S/E) At marker 419, take the left bank track up the torrent, then a second track on the left to cross over a wooden footbridge to marker 380, further east than shown on the map (0h15). Go up to the right, following the yellow markings, and the path leads to the beautiful Cascades de Peïrastrèche (0h30).

(1) Continue to marker 423 (0h15) just above the Peïrastrèche bridge.

This passage is no longer possible since storm Alex. At the end of the track just after the start, turn right and follow the GR®52 to the Pont de Peïrastrèche.

(2) Continue up the right bank to marker 424 (0h20).
Leave the left-hand path and continue on the GR®52as far as marker 425 (0h05).

(3) Leave the path on the left that leads to the Refuge de la Cougourde. Cross the torrent and climb a steeper slope to reach marker 427 (0h45) at the foot of Lac de Trécolpas.

(4) Turn right to discover the magnificent Lac de Trécolpas with its island (0h10).

(5) Take a break to look around. To get to the refuge, return to marker 427.

(4) Take the path to the right that passes through a large scree marked with cairns. This continues up the mountainside, crosses a magnificent torrent and arrives at the Refuge de la Cougourde, marker 426 (0h40).

(6) A return trip to Lac des Peatlands is possible by turning right (of no interest).
At marker 426, as you come from the refuge, turn left and climb a fairly steep slope to reach a large stone scree and the small lake where there was not much water left (0h30).

(7) The return journey takes the same route, with the chance of seeing a few chamois.

From the refuge, the descent begins with a steep climb back to the crossroads taken at the start at marker 425 (0h25) and the GR®52.

(3) Follow the path in the opposite direction, passing waymarker 424 (0h05) and continuing along the GR®52as far as the Pont de Peïrastrèche, waymarker 423 (0h10).

(2) Cross the torrent and after a few hairpin bends, arrive at Chalet Vidron, marker 422 (0h15), well hidden behind a small pond in this thick forest.

(8) Continue through the forest to reach marker 421 (0h15), take the path through the forest and then turn left onto a track leading down to the Vacherie du Boréon and the car park, marker 419 (0h15) (S/E).

Beautiful autumn hike. Well-maintained trail with lots of lovely steps. The car park is accessible despite the roadworks. Saw some chamois on the way up, at the partially frozen lake, which is normal for this season, a mother chamois and her young, towards the bottom of the lake. All the other hikers stayed near the lake, in the sun, so we enjoyed watching them, then a stoat in its winter coat put on a show for us. The lake remained almost completely in the shade and the wind was icy.
We returned via the refuge, where a magnificent male chamois was resting 15 metres from the chalet, completely unafraid, and we passed within 10 metres of him. We didn't go any higher, as the days are short at this time of year.
The route was quite busy for the season.

This is a pleasant hike with no technical difficulties. The path between B427 and B426 can be tricky in wet weather. Many of the roots can be slippery, and as the path is on a slope, it can be dangerous. The detour via Lac des Sagnes is not essential at this time of year as there is not much water in the lake.

I was very pleasantly surprised. The trail is very easy, quite physical, but be careful at this time of year with snow and ice, so remember to wrap up warm. It's windy at the top.
Be sure to return before nightfall, as sunset is around 5:00–5:30 p.m.
We didn't see any ibex.
Enjoy every moment and every ray of sunshine.

A very beautiful hike, accessible to everyone. No difficulty.
A beautiful day, the lake is perfect for a picnic break.
Unfortunately, we didn't see any ibex, but there were cows instead.
The return trip via the Cougourde refuge is easy, but watch out for the scree slope, which can be hard on your ankles.
The only downside is that it gets quite busy.
I would come back to camp here.

A very beautiful hike with my 8-year-old son, with lots of ibexes to everyone's delight. Simple and accessible, we weren't alone 😁 but once we arrived at the Cougourde refuge, I read that the Lac des Sagnes wasn't particularly interesting, especially as it was dry.
The little one was hot and full of hope to see things.... We weren't lied to, there was no water 😅 but the short climb of about twenty minutes to the lake meant we were alone, which was very pleasant. And even though the lake we had hoped to see wasn't there, we did see some chamois and, best of all, we were at the top of La Cougourde, which is well worth the detour.

Easy hike to follow with the description and signposts on site. The landscapes are magnificent, and there are many ibexes. Hike done on 15 August, a popular route but still fine compared to some hikes in the Alps and Pyrenees.

Hike as described, to the lake and then the refuge.
Great encounter with the ibexes: the lords of the rocks. ⛰️🐐🥰
I couldn't get to the Lac des Sagnes, I couldn't see the route.🙃

Walk made on 02/05/2025
Nobody, a few chamois in the névés above the lake
Still a lot of snow: we arrived early in the morning; the névé below the lake is very hard snow, so we need to be well shod (Vibram soles, no trainers!).
We wanted to climb to the Pas des Ladres but we didn't bring crampons...
We did the traverse to the Cougourde refuge (closed): lots of chamois and ibex.
A very nice tour to do "out of season"; it's "packed" in summer...

This was a very nice walk on a bank holiday in November, so it was very busy and especially popular with the general public. When we arrived at the lake, we were amazed by the beauty of the site, but unfortunately it was marred by the behaviour of some people who clearly didn't want to enjoy the peace and beauty of nature.

As for the route, we had no trouble following it (note that part of the path is closed at the start). We did it in 4 hours.

A very nice walk, on a very well-maintained path.
We went straight up to Lac de Trécolpas with my daughter, without passing through the refuge.
There were a few hikers at the lake, but not too many.
We had our first encounter with chamois just before turning off towards the lake (marker 425), close enough to take some great photos.
The last part is a bit steep, but frankly it's worth it (another encounter with chamois at the start of the last section up to the lake - about 100m before marker 427).
Arriving at the lake, what can I say... it's magnificent.
My daughter spotted 2 chamois again, which we were able to approach from the water's edge at the far end of the lake, right at the foot of the large scree, near the ford that leads to the small island.
We decided to have a snack and a siesta on the island before setting off again.

Just before leaving the plateau, we spotted two more chamois, not too far from us on a large boulder at the start of the path back down.

On the way back, we passed quite a few people coming back down and had the pleasure of walking halfway back with a lone hiker with whom we had a good chat. A very friendly gentleman.

It was a wonderful day, with some very beautiful images in our minds and in the camera.

To be repeated ...

hike made as a couple on 6 august 2024
Very nice walk, well signposted and well informed. The climb up to the lake was easy, but we were glad to get to the lake and enjoy a good break. The lake was magnificent, and there were still very few people, which was good, and we were able to get close to the chamois, which were not very shy. We set off again in the direction of the Cougourde refuge, and already we were passing a lot of hikers on their way to the lake. We continued on our way, crossing a number of rocky areas and fording several streams on the way to the refuge. Lots of hikers joined us for a picnic and blueberry tarts on the terrace. We had no trouble getting close to the chamois, which seem to have taken up residence near the chalet. The descent was a little tricky at the start, but as on the way up, nature is marvellous and the water in the torrents is clear and plentiful.
