Laquet du Riou Grande above Bénaquès

A lovely little, little-known lake, nestled at the foot of Montaigu.
The .gpx track is essential after the Cabane de Bénaquès, or alternatively, you’ll need good map-reading skills and a sense of direction.
If there is fog or you have difficulty finding your way from the Laquet (5), return to the Cabane de Bénaquès (4) and retrace your steps along the outward route back to (S/E).

Description of the walk

From Bagnères-de-Bigorre, take the D935 towards ‘La Mongie’ – ‘Payolle’. After the village of Beaudéan, at a wide left-hand bend, leave the D935 and turn right onto the D29 without crossing the Adour de Lesponne. After 10 km, the road ends; park in the Chiroulet car park.
(S/E) From the car park, walk back down the D29 for 600 metres and turn left onto a track heading due north-north-east.

(1) After 250 m, a chain blocks access to motor vehicles. Go over it and continue climbing.

(2) After 800 m, turn left heading due west, now following a cairn-marked path that climbs steeply through the forest and cuts across the track in places. Follow the cairns carefully. Leave the forest after crossing a small stream, before emerging onto a large mountain pasture. Head due north towards the “Cabanes de la Lit”.

(3) A stunning view of the mountain range – a great spot for a break.
Above the restored huts, take the small path heading north-west as it climbs up through the mountain pasture. The path turns due west to cross the Riou Grande. Continue along the path heading south-west, which leads to the Cabane de Bénaquès.

(4) If in doubt or unsure, you can head straight to (6).
The Ruisseau de Bénaquès flows at the foot of the cosy hut. Another lovely viewpoint over the Chiroulet and Ourrec valleys.
Look for a narrow track on the left bank that heads due north and climbs steeply. After about thirty metres, the track becomes a path that continues to climb steeply due north. Once you’re overlooking the stream, the path levels out and very quickly leads to the tiny, pretty little lake at the foot of the Montaigu. A lunch break at this little-known spot is a real treat.

(5) Please note: in the event of fog or if you are unsure of the direction, turn back and return via the same route you took on the way there to (S/E).
Carry on a little further and join a path slightly higher up that takes you back along the same route. Join the path you took on the way up, turn right and head back down to the Cabane de Bénaquès.

(4) If in doubt or unsure, you can head back the way you came directly to (S/E).
Head south-southeast, staying on the mountainside for 50 metres. You’ll soon come across a path that crosses the stream (which is sometimes dry). Now descend gently, due south, towards the forest (200 metres from the hut). Keep a close eye on the cairns along the path, which turns into a stony track. Continue for about 1 km.

(6) Follow the track which branches off to the left, heading due north-east, and winds round a few bends before heading due south again. After crossing the Ruisseau de Bénaquès, the track turns right and descends steeply. You’ll reach a junction where several tracks meet.

(7) Take the track that bends sharply to the left. It leads to the little chapel of Le Chiroulet. Then turn left onto another track: the car is 200 metres away, a little further down (S/E).

Notes

You’ll need some basic orienteering skills from the Cabane de Bénaquès (4) to continue the hike.
Please note: the track is often damaged by forestry machinery between waypoints (WP) (6) and (WP) (E).

Spring to the left of the Cabanes de La Lit.
The huts are in use and should be treated with respect: there’s a long history behind them.
The Bénaquès hut is comfortable and should be treated with respect.
If rain is forecast, it is strongly advised not to descend via the tracks from the Bénaquès hut. Indeed, if timber felling is taking place, the final section may be muddy between points (6) and (S/E).
In poor weather conditions => a return trip to the Bénaquès hut is the wiser option.
We are in mid-mountain terrain, so you’ll need a windproof jacket, walking poles, a packed lunch and 2 litres of water.
A 1:25,000 map, route description and either the GPX file or the PDF are required.

The return from point 5 to point 4 requires careful attention as there is no marked route, particularly over the final few metres of the circular loop from 5 to 4

Hike requiring minimal navigation skills, little-used route, no clearly marked trail which can become obscured by vegetation after the Bénaquès hut.

Circuit done in good weather. After a climb through the woods, a magnificent discovery of the Cabanes de la Lit. The path becomes narrower as it continues towards the Bénasquès hut. From there, the start of the path to the lake is not visible. Follow the description to find the path, which becomes well marked a little higher up, or use the GPS track to reach the Riou lake, which is almost dry at this time of year. Magnificent view of numerous peaks. On the way back, pass the Bénasquès hut again and continue for about twenty metres to find the return trail, which leads to a very long forest track that you follow to the car park. The steep track is almost dry and the tree cuttings have been cleared.

Hike done as a pair
The landscapes and views are very beautiful.
We particularly liked Courtaou de la Lit and its huts, which were built stone by stone over 30 years by Georges Buisan to recreate the hamlet as it existed in the 19th century.
However, we were disappointed with the Riou Grande lake, which, due to eutrophication, is no longer really a lake because of the proliferation of vegetation.
On the way back, from the Bénaquès hut, we were unable to find the indicated route, so we returned by the same path we had taken on the way there.

I completely agree with the previous comments; we had some difficulty finding the path to the small loop above the lake, which led to a somewhat challenging descent down the cliffs. It was partly our fault because we didn't follow the GPX track closely enough. Coming down after Benaques, there was a nice little path on the hillside, but unfortunately it wasn't the one on the GPX track, so we had to cut through the woods to get back to it. It seems that the GPX track is off the trail at that point. But the walk was nice, we enjoyed it. The Courtaou de Lit huts are superb. At this time of year, there is no livestock and little vegetation. It took us much longer than 4 hours and 40 minutes!

A very beautiful route that is also not very busy. The Chiroulet car park was completely full. There were five of us and we only met one other person and a group of six! And even then, they didn't climb up to the lake. Be careful on the way back, though: at the lake, we couldn't find the path that takes you on a short loop to the Bénaquès hut. And when you leave the hut, you have to head east straight away rather than following the path that goes due south, in order to reach the forest.
However, for most of the route, although the path is not marked, there are cairns that are judiciously placed.

Hello,
I would like to know if the hike is signposted? Would you recommend it for children? (9-16 years old)
Thank you.
