Roc Blanc via the Étang de Laurenti

This climb in the sunny Pyrenees is a real classic, which means it can get quite busy in good weather. However, the magnificent Étang de Laurenti and the 360° view from the summit of Roc Blanc are well worth the effort required during the hike.

Description of the walk

The start is from the car park near the Refuge Forestier du Laurenti, on the forest road in very poor condition that we took from the hamlet of Le Pla on the D16.

(S/E) Head south towards the bend in the forest road and turn left into the forest onto theGRP® du Tour du Pays du Donezan. Follow the yellow and red markings for most of the hike.
The path climbs steeply southwards, then heads south-west and levels out at the Cabane de Counc meadow.

(1) Continue climbing until you reach a small ledge that blocks the basin where the Étang de Laurenti is located.

(2) Take the time to linger on the banks, sheltered by pine trees, while keeping an eye on the Roc Blanc, which dominates the valley floor on the right.
Walk along the right side of the lake and continue on theGRP®, which is almost flat at first, then climbs to follow the base of the Roc Blanc. The pretty Ruisseau de Laurenti flows below on the left.

(3) At a small pond, turn right at a 90° angle and continue to follow theGRP®, which then heads north-west and climbs quite steeply to the Col de Laurenti. This is the most challenging part and a break at the pass is welcome.

(4) Leave theGRP®, which descends, and continue towards the Porteille de Barbouillère. Turn right onto a very steep climb heading northeast, where cairns mark the path. The route is obvious.

(5) At the ridge, which offers an impressive view of the north face of Roc Blanc, turn right and quickly reach the peak.

(6). We are at an altitude of 2,542 metres and the view is breathtaking. The return journey is via the same route, from which you can enjoy a long, uninterrupted view of the Étang de Laurenti, which you passed on the way up.
After the lake, follow the same route back to the car park at the Laurenti forest refuge (S/E).

Notes

The forest road you have to take to get to the start is in very poor condition. Be careful with vehicles with very low ground clearance.

There are no water sources on the route. It is therefore necessary to take adequate supplies, especially in summer, as the route is in the sun after the pond.

Good hiking boots that support the ankles are essential. Hiking poles will also be very useful, especially on the descent after the Col de Laurenti on the way back.

Worth a visit

The Pic de la Camisette is fairly easy to reach from the Col de Laurenti. Allow an extra two hours for the return trip.

The Étang de Quérigut, easily accessible from the forest road.

Stunning 360° panoramic view at the summit! Lovely walk.
Just to clarify: I covered a distance of 12.5 km with an elevation gain of 1,015 m.

A very beautiful hike with a magnificent view as a reward for the steep climb.
We took the noisy forest track (which starts near Mijanès) to get to the refuge car park more easily by car.

A superb hike for couples!
A good climb from the lake to the summit!
We took the forest track from Le Pla. It's a bit rough at the start, but honestly, even with a standard car like a Clio (we had a Dacia Sandero Stepway),
If you drive carefully, the track is fine.

A popular route up to the Laurenti pond, then it gets much less crowded. The forest road is in very poor condition. It's a shame it isn't maintained a little better... but everything has a price...We climbed up to the small pond, which was dry, but we didn't have enough time to climb the 300 metres to reach the Roc Blanc. A pretty, very pleasant spot, worth revisiting if access improves one day.

The access road to the Laurenti refuge, whether via Le Pla or La Restanque, is practically impassable. Watch out for punctures and drive very carefully.
Hikers should not be allowed to use such forest roads. Tourists do not drive 4x4s!
Apart from that, the hike to the Laurenti pond is magnificent, especially in autumn.
This is a very popular route.

Access to the start of the hike (refuge) by car is impossible due to signs at the start of the forest road: the path seems to have become impassable (unless you have a 4x4?). We gave up.

There were many people around Lake Laurentin. There were about ten of us at the summit. The end of the climb to the pass is steep.

A little difficult to find your way between the Col du Laurenti and the Porteille de Barbouillère.
Very interesting walk (lake + summit), shame it's a bit far to get to when you live in Toulouse (3 hours' drive!).
There were lots of people on the trails with us, especially between the car park and the Col du Laurenti.

Nothing to say about the hike itself: it's one of the most beautiful in the Pyrenees, especially when there aren't many people around.

Regarding access: the forest road from Pla is in poor condition, but it is still passable even with a low-clearance car, as long as you drive carefully. Allow 30 to 45 minutes to drive it safely.
Do not take the forest track that leaves from Mijanès (despite the signs encouraging you to do so). It takes an hour to drive along it and is a real ordeal. It has been damaged in many places, probably also by forestry work, and "patched up" with large, rough crushed stone (not gravel at all). We still wonder how we avoided getting a flat tyre. There are also lots of broken blackcurrant bushes, which are great for parallel parking. The Woodstock-style gathering (at least a hundred vehicles) that was taking place there during our trip didn't help matters.

Very beautiful hike.
We parked at the forest house.
Very few people at the lake, a few patches of snow.
The white-tailed woodpecker lives up to its name.

Hike only to the lake, in recovery mode. On the two occasions I was able to go, with snow at the end of the season (April) and at the beginning (December), it was possible to do the route without snowshoes, but after the lake it's a different story. next time, I'll climb to the peak! In any case, this part of the route is a pleasant walk through the forest with magnificent light and colour effects. The impressive cirque at the foot of the white rock, a frozen lake and fun footbridges. We parked the car before the chalet, which added about 40 minutes to the walk, but that wasn't too bad.

A very popular route, but still as beautiful as ever.
The forest road from Pla is bumpy and not very wide.
We recommend taking the forest track that leaves from Mijanès, which is wider and was in better condition when we passed through.
