The Dent d'Orlu

The Dent d'Orlu or Pic de Brasseil is known to climbers for its south-east and south faces, the latter offering a vertical wall of over 1,000 metres. However, its north face, although very steep, is accessible for hiking, as described here. It offers an interesting viewpoint over the Ariège mountains as a whole due to its central position.

Description of the walk

Park your car at the roundabout at Jasse de Cabane Longue, known locally as the Poêle à Frire.

(S/E) Altitude 1,512 m. The trail, which is very well marked (in yellow), heads east and crosses a stream. It climbs rapidly through a beautiful forest of beech and birch trees. Head generally south-east.

(1) Altitude 1,815 m. The trail emerges from the forest onto the Sarrat de la Llau, where the view opens up on both sides. The direction turns more sharply southward. You can clearly see the north face of the Dent, where, to the right of a large slab, you can make out the trail that leads to the summit.

(2) Altitude 1,960 m. You reach the small Col de Brasseil, where a sign indicates the direction of the Col de l'Egue to the south-east and the Dent to the south-south-west. It is impossible to go wrong: the north face of the Dent is straight ahead. All that remains is to climb!
There are no more markings, but the route is obvious. The slope is very steep, surrounded by rhododendrons and blueberries. You will sometimes need to use your hands to pull yourself up onto the large rocks, which form uneven but generally very stable steps. Be careful of a few wet, slippery sections. Just before the summit, bear left onto a rocky, stony slope.
You will reach the marker (2,222 m) at the summit of the Dent d'Orlu.

(3) Be careful on the descent from the Dent. You may need to use your climbing technique to get down. Return via the same route to the car park (S/E).

Notes

Access by car:
Coming from Ax-les-Thermes towards the Col de Pailhères (D25), after Ascou, follow the Lac de Goulours. At the eastern end of the lake, turn right at a sequoia tree at a place called "La Forge" (stopover lodge), cross the Lauze stream (keep left) over a bridge and continue on the track that runs along the other side of the lake towards the south-west, then make a large loop to the left and climb eastwards then south-east to an altitude of 1,500 metres at a roundabout known as "la poêle à frire" (Jasse de la Cabane Longue), where you can leave your car.

There is no water on this route.
Mobile phone reception is sporadic and random.
Excellent trail becoming very steep, difficult and uncomfortable on the last part of the ascent (painful on the descent).
The overall level is "Moderate", but the summit section (which is unwise to attempt in wet weather) is more "Difficult".
Information provided for the summer period. Avoid this route when there is snow.

Worth a visit

The Orlu Reserve.
The Col de Pailhères, which is often featured in the Tour de France.

Being a lone wolf, I had to do the Dent d'Orlu, and thanks to this superbly designed website, which I am grateful exists, clean, clear and with plenty of information provided

It's a very enjoyable walk that I would definitely recommend. It's technical but entirely doable in good weather. However, avoid it in rainy weather or the day after rain, as it will be slippery and dangerous.
As for how to interpret the walk, I would say it's up to each individual, as we all have different perceptions of difficulty.

In any case, as long as it is signposted, it is very reassuring.

I'm really grateful to the website and its administrator for keeping it alive

A beautiful walk with magnificent views of the hills!
The walk is divided into three parts: forest, meadow and mountain pass. There is a significant elevation gain throughout almost the entire walk. In the meadow section, you will find blueberries, which are delicious and will help you recharge your batteries!

Be careful, however, as the route is difficult in wet weather. Access by car is impossible due to mud and slippery stones. The last part (from the Ascou sign) is difficult, with a significant elevation gain. The last kilometre should be avoided with young children.

A beautiful hike with a steep climb at the end where you need to use your hands and be careful.
It's a shame that when we reached the summit, we were greeted by flying ants, which spoiled the pleasure of staying up there a little.

A very beautiful hike. The first part is through the woods, arriving at a slight incline towards the Dent d'Orlu climb, where the serious part begins. After this warm-up, you get the main course with a good climb, but afterwards you are rewarded with a superb view from the top. I highly recommend it.

A beautiful hike. As is often the case in Ariège, the climb is immediate and steep. The last few metres must be covered with the help of your hands and sometimes by scrambling down. The track leading to the poêle à frire is quite long and quite rough. Low-clearance vehicles should avoid this route.

The route was completed in beautiful weather. There was a steady slope from the start. The climb up to the summit bastion requires using your hands to get across the slabs, but it's not very difficult. The route is very well marked. I made a video with the names of the peaks, which describes the atmosphere of the hike and shows our route and the slab passages.

Forest track to reach the car park in poor condition but passable if you drive slowly. Very well signposted hike with a steep climb over a short distance! You need to use your hands in several places, but it's not too difficult on the way up or down. However, when we reached the top, we were surprised by a large number of flying ants! So we came down faster than planned, but it was still enjoyable!

A very beautiful hike with children aged 9 and 12. It took us 2½ hours to climb at a leisurely pace, especially the last part, which was quite challenging (as was the descent). Superb views from the summit, where several climbing routes converge.

A fairly challenging hike, with no time to warm up as the elevation rises very quickly, especially in the final ascent; but the view from the top is spectacular.

Nice route, the track to the start is easy to follow and you get there safely if you take care.
The climb through the woods is fairly steep, but then there's a lovely route with 360-degree views all the way to the pass.
Before you leave the first wood, there is water where you can wash your hands and cool off on the way down.
The climb up to the Dent d'Orlu is well marked. For the last 50 metres of the climb, you need to use your hands, but it's not too difficult.

A superb hike rewarded with breathtaking views at the top!
The last part is a real climb (it took us an hour) and the last few metres can be challenging as you have to use your hands (and even your bottom to get back down!).
Please note: the forest track is quite long (30-45 minutes because you have to drive very slowly) and is in very poor condition, to the point that I can't imagine a low-clearance car attempting it (or a car whose owner is very particular about branch marks on the doors )

Completed in October 2021, no particular difficulties with the route, well marked. Already a few patches of ice that are easy to avoid but require caution as the trail is very steep towards the end. The access track to "la poêle à frire" is not in very good condition but is still passable with a standard vehicle, just take it slowly.
