Circular route to the summit of the Coume de Bourg and the Pic de Céciré

A lovely, little-used circular route starting from the village of Castillon-de-Larboust. A slightly steep climb through a pretty valley, followed by a ridge walk offering magnificent views across all the mountain ranges of the Central Pyrenees. The paths are not signposted and are sometimes barely marked, but it is easy to find your way by sight with a basic sense of direction. A short section on the descent from the summit of the Coume de Bourg may be tricky for those prone to vertigo.

Description of the walk

Enter the village of Castillon-de-Larboust, accessible from Bagnères-de-Luchon via the D618, then take the small road that winds down below the Church of Saint-Pierre, cross the river (Neste d’Oô) and continue up the opposite slope. After thethird major hairpin bend from the bridge, carry on for 500 metres and turn right onto a road that quickly turns into a track easily passable by car. Carry on along this track, past the barns at Labach, until you reach a hairpin bend beneath a hydroelectric installation (a tiny dam with a small building). Park along the track at the hairpin bend (alt. 1,450 m).

(S/E) Take the faintly marked path which climbs up the valley facing due south, keeping the stream on your left. Make your way along, trying to follow the path clearly; if not, proceed by sight, keeping to the right-hand side of the valley until you reach the Cabane de Barguères, which will be visible on the right

(1) Continue, heading first to the right, then quickly due south until, after a rocky outcrop, you reach a sort of jasse or grassy plateau (1,982 m).

(2) From there, follow the path, keeping an eye out for a rocky outcrop on the right which you’ll need to go round to the left. The ascent takes place up a fairly steep grassy gully, heading south-east. Then head for the clearly visible ridge on the right and join it.

(3) Continue along the ridge, heading left (south-west). The path is better marked and leads quickly – with a slightly steep but unchallenging final stretch – to the summit of the Coume de Bourg (2,367 m).

(4) From the summit, continue along the ridge path heading due east. The path is marked, and you may occasionally need to use your hands, but there are no particular difficulties, except for those prone to vertigo. Reach the junction with the path coming from theGR®10.

(5) Continue along the ridge towards the Pic de Céciré, which is clearly visible and can be reached fairly quickly.

(6) From the Pic de Céciré (2,403 m), follow the ridge as it heads northwards, taking care not to get too close to the rocky barrier on your right. The path is poorly marked. Continue along the western slope of the ridge until you reach a pass (alt. 1,820 m).

(7) Descend into the valley, staying above the forest below, then turn right, following a contour line trodden by animals. Reach a ridge line.

(8) The track below is clearly visible: join it.

(9) Take the track, heading down to the left, to reach the starting point of the walk in a few minutes (S/E).

Notes

Standard hiking kit, good walking boots. It is possible to stay overnight at the Barguères mountain hut.
This hike should be undertaken in good visibility and dry weather. Not recommended for those prone to vertigo. A challenging hike due to the steep slopes and significant elevation gain. A basic sense of direction is required.

This route passes through a protected area, which may be subject to special regulations:

Worth a visit

Magnificent views along the entire ridge between waypoints (3) and (7).

A very beautiful hike, but one for experienced walkers. From the ridge, you have views towards the 3,000-metre peaks to the south, the GR 10 beneath your feet, and the ski resorts of Peyragudes to the right and Superbagnères to the left.
From the start to the Barquères hut, head due south, as the trail marks on the ground are faint. But you’re sure to find the hut (one mattress, I think).
From the hut to the rocky outcrop, there’s no problem – the path (starting to the right of the hut) is relatively well marked.
After the rocky outcrop, head right to find a path; about halfway along this path you’ll lose your way – the route on the map differs slightly from the author’s (which is more direct) – but in any case, your GPS will put you back on the right track; reaching the ridge is straightforward.
The rest of the hike presents no navigation problems.
Between points 4 and 5 there are a few small rocks which you can avoid by staying on the earthen path; however, between points 6 and 7 I crossed two short stony sections, but without any difficulty. On this final stretch, the path is mainly earth and pebbles, then further down the path disappears (from time to time) beneath the vegetation.
I drank 1.5 litres of water (having had a drink before setting off); there is a spring (which I didn’t try) marked ‘Source de Savent’ before you start the climb up to the cliff. A sunny morning, but stormy weather in the late evening (be careful).
However, unlike the author, I completed this route in 8 hours (including a few stops and photos).
A very beautiful route for experienced walkers and a lovely valley.

Hello Jbaudry,

It’s true that the route along the ridge is quite a risky one, especially with two children. Having done it on my own, I found it quite challenging. There are two factors to bear in mind: the fairly steep climb and the Céciré peak, with its technical sections and signage that isn’t immediately obvious. But I agree – this hike is best suited to experienced and well-equipped walkers. If you’re doing it in hot weather, make sure you take plenty of water – at least 3 litres per person. I found myself running out of water just as I reached the summit of the Coume de Bourg – it looked like I was in for a real scare, but it all turned out fine in the end.

An extremely quiet walk; as a result, the paths are barely visible and difficult to follow. The only highlight is reaching the summit of the Coume de Bourg and then the Pic de Céciré. The return journey along the ridge path was a real ordeal. We (two adults and two children aged 9 and 11, who have been hiking for several years) took eight hours to complete the circular hike; I wouldn’t recommend this hike unless you’re a very experienced hiker.

Hike completed on 14 July 2023, clear skies, bright sunshine. Very little shade. The climb isn’t easy – it’s worth noting. Once you reach point 6, a little further on, there’s a rocky section on the descent that isn’t necessarily straightforward to navigate and is somewhat technical. Without walking poles, it seems difficult to me. Remember to take more water than usual; you often tend to drink more during steep climbs. I ran out of water just as I reached the summit of La Goume, having arrived lower down when it was completely flat. I only came across one other person on the way up. A lovely hike despite that scare; the 360-degree panorama from the summit of La Goume is magnificent. Between point 7 and point 8, the setting sun is also absolutely stunning. Thank you for the very precise GPS route.
