Bessons Lakes

The Bessons Lakes are among the most beautiful and airy in Boréon. The striking glacial relief, with the passage of barriers defending this cirque, is truly awe-inspiring.

Description of the walk

Cross the village of Saint-Martin-Vésubie and take the D89 towards Boréon. After the lake, continue right on the D189 and park in the lower car park of La Vacherie du Boréon.

(S/E) Head towards Chalet Vidron, pass between the Vacherie buildings and reach the upper car park. Continue through the forest (towards Pont de Peïrastreiche, Chalet Vidron) along a clearly visible path. Go around a pond on the right towards Chalet Vidron (hidden in the woods) and cross the wooden bridge at Peïrastrèche.

(1) Walk a few metres and, at the fork, continue uphill following the stream. Cross three wooden footbridges.

(2) Take the small path that starts on the left and climbs into the forest (if you arrive at the junction marked "Refuge de la Cougourde 0h30", "Lac de Trécolpas 0h45", "Pas des Ladres 1h45" a few metres before crossing the stream, you have gone too far and should retrace your steps).
The climb is quite steep until you reach the Vallon de Sangué, where you will see the Cime de Baissette.
The trail then follows the stream at a leisurely pace through beautiful surroundings.

(3) At the end of this valley, take the path that climbs up to the right and follows the small stream on the far right, then pass between the rock piles to reach the Vallon des Lacs Bessons.
From there, cross the stream and climb quite steeply up the scree, following the cairns to the first lake. The second lake, connected to the first by a small waterfall, appears just behind. Go around to the right, reach the highest point to discover a third small lake and look out over the three lakes.

(4) To descend and return to Lac des Sagnes, the path is almost invisible at the start but it is fairly easy to find in clear weather.
Follow a small valley between the rocks that goes around point 2558 on the left (a rocky peak about a hundred metres away with a cairn on top). The valley then becomes more pronounced, the route is well marked by cairns and there is a beautiful view of Lac de Trécolpas. Continue downhill, passing to the right of a small lake, then arrive at a steeper slope. The trail follows a small scree slope well marked by cairns to Lac des Sagnes.

(5) Before the lake overflows, turn right and follow the stream downhill until you come to a pretty little waterfall. Continue to the Refuge de la Cougourde, then take the path on the left for about 50 metres.

(6) Turn right at the descent (towards Vacheries du Boréon) and join theGR®52.

(7) Continue on the right, rejoining the path you took to climb up to the lakes.

(2) Take the same route back to the car park (S/E).

Notes

You can also start from the second car park at Le Boréon, located above La Vacherie, if there is space available.
In foggy weather, I recommend returning from the lakes via the same route, as the return via Lac des Sagnes is tricky for the first 200 metres or so (the path is not marked).

A sublime hike.
The path is not easy to find for much of the hike, with no markings other than cairns. Steep climb well before the ruined hut and steep descent via the Cougourde refuge to the refuge. Ibex and chamois.
Done in autumn, magnificent scenery with beautiful colours.
One of the most beautiful hikes in the Mercantour and, above all, without over-tourism, so it's peaceful, which sometimes allows you to come face to face with animals and get very close to them. 💜💜💜

A superb hike, but you first have to find the first fork in the path, which is just after the Sangué valley, easily recognisable after Storm Alex, which left very impressive traces of erosion. Then the climb is straightforward, apart from its length, and you're happy to arrive at the lakes. The descent is dotted with cairns arranged in a somewhat anarchic fashion, and the Visorando app was a great help. The general idea is to keep to the left. Then there are no problems until you reach the Cougourde refuge.

A beautiful hike, but demanding and physically challenging in terms of distance, duration and elevation gain.
A lovely area, Le Boréon is always a pleasant starting point.
first hesitation: finding the trail that climbs up to Les Bessons. When you reach the sign just before the bridge over the stream, you've gone too far and need to retrace your steps.
The climb to the lakes is difficult: first through the forest, then along the stream, and finally, to finish you off if you have any strength left, there is a pile of rocks to climb over.
The arrival at the lakes is great, with several secluded spots to have lunch. There was a chamois hanging around. Reading the other comments, this is the place to find them! This one came quite close, but it was shy (even though it is obviously used to human presence, as the place is frequented in summer).
I got lost when leaving the lakes and was never able to reach Lac des Peatlands, even though I saw it several times when leaving Les Bessons. The descent was very difficult.
When I arrived at the refuge, there was nothing special to report, and the trail to follow next presented no problems.
I was very happy to find my vehicle, I couldn't take any more.
I won't be doing it again, it's really difficult.

A very beautiful hike but difficult to follow. Fortunately, the app makes it much easier for us, because otherwise there are no marked trails and only a few cairns.
The descent is quite difficult on the scree slopes.

Hike done in the opposite direction, passing first by the Cougourde refuge; very challenging circuit
Magnificent hike, we only came across one other hiker but saw lots of ibex and chamois around the lakes and on the way down. 🤩
Among the most beautiful lakes in the Mercantour

Hello, I did this hike on a Tuesday and only saw one other hiker after stage 2, which takes you off a fairly well-travelled trail. From there on, I was alone with the chamois. From stage 2 to the lake, it's quite a climb. The start is in the shade, but the forest quickly gives way to rocky terrain. After stage 3, you have to rely on cairns to stay on track at times. You can stop at the lake for lunch. I was alone with two chamois for company, which was great! The descent to the refuge has a few sections where you have to watch your step. But it's nothing insurmountable, and I didn't have any walking sticks. Even if the start may seem a bit crowded, from stage 2 to 6 you're really on your own with superb scenery. I recommend it.

Magnificent landscapes! They are well deserved because the climb, like the descent, is quite steep.
But why are there so many cairns at the summit, above the lakes? They serve more to confuse us than anything else. Especially since there are no markings, only the cairns can help us, especially if visibility is poor.
Thank you in advance to my fellow hikers for not piling up rocks anywhere!

A magnificent hike that passes by several small lakes and waterfalls, with very few other hikers.
We had trouble finding the path from the Cougourde refuge. We followed the waterfall and then started climbing.
The climb was really hard and steep, but once at the top, the view was amazing!
The return trip was along the stream, which was really refreshing and pleasant.
We were lucky enough to spot some marmots

A magnificent hike, which we finished by descending via the lakes of Sagne and Trécolpas.
There were lots of flowers, a few chamois and very few people.

Superb hike!
We did the route in the opposite direction because we first went to Trecolpas Lake and then headed for the Cougourde refuge. The rest of the hike is quite difficult! The climb is very steep and rugged, and we had fog, which made it difficult to see the peaks.
Despite everything, once we got to the top, we really appreciated the scenery. Superb!
The descent in the other direction seems slightly less difficult but just as long and steep, and we saw lots of chamois and ibex.
I would recommend this hike to people who are in good physical condition and have some experience!
Have a good trip!

The trail starts at La Vacherie du Boréon and climbs gently until it reaches the forest, where it begins its ascent towards the two valleys. The trail is rarely used, if at all (we only encountered one group of three people during our climb to the Bessons lakes), but it is well maintained and marked with cairns if you ever lose your way.
Once you've climbed the pass with a little effort (it's quite steep, but doable), the first of the Bessons lakes comes into view. It's superb! A lunch break is a must after three hours of walking (we took our time) to recharge your batteries and continue the short climb to overlook the three lakes. The view is incredible.

The descent to the peatland lake is rather tricky, so pay close attention to the cairns that show you the direction at first, before finding the small path that will lead you there more easily.
A quick detour to the refuge to watch the chamois enjoying themselves gives us a chance to catch our breath.

We didn't head straight back down to La Vacherie, but took a detour via Lac de Trécolpas, which is not to be missed. It's not far from the refuge and is fairly easy to reach (even after 13 km on your feet, I promise). The trail downhill after enjoying the (superb) Lac de Trécolpas takes you back to La Vacherie without having to go back to the refuge.

A beautiful loop, to be done again and again and shared with others!

Having completed this circuit in both directions, I can confirm that it is easier to climb up to the COUGOURDE refuge and then head towards Lake SAGNES and, just before reaching it, turn left and follow the cairns up to PC 2516m
It is well marked, safer going up than down, especially if the rocks are a little wet.
The return via the SANGUE valley is a bit long but not difficult.
