The Soum d'Andorre and the Soum de Conques via the ridges

A very pretty circular reserved for very good walkers who are not afraid of heights. The hike is classified as difficult because of the passage over a ridge, but there are no particular dangers anda good sense of direction is essential. (¹)
Part of the return route is quite steep, after the Col de Las Escures.
This hike should only be attempted in the absence of snow and rain.
The GPX track is essential for this route.

Description of the walk

Access: From Lourdes, head towards Cauterets and Gavarnie on the D821 dual carriageway. Take the second exit at the end of the straight road towards Argelès-Gazost D921B. Pass the first village of Vilados and turn right at the next crossroads towards Ouzous and Salles D102. When you reach the village of Salles, continue left at the church, still on the D102. After 150 m, turn right onto a very narrow road between the houses. A yellow sign indicates Col d'Andorre 6 km. Continue along this small road, ignoring the adjacent roads and paths. After about 4.5 km, at altitude 936, the road becomes a moderately passable track. Take care with low cars. Pass altitude 1031 m, and 300 m after, you will arrive at a clearing on the left with an information sign. On the right is an area with a fence and a large drinking trough. Park here.

Red and whiteGR® 101 markings.

(S/E) Car park with wooden table. A yellow sign indicates the direction of Col d'Andorre. Follow this sign heading due west, following the track for 300 m.

(1) Fork in the road. Turn right, heading due north, and climb up a track suitable for vehicles. Please note: there are no signs. Follow the red and white markings forthe GR®101. After a few metres, go through a fence. Close the gate behind you and continue climbing up the track. The track turns north-east.

(2) Fork: at the bend to the left of the track, turn right and continue climbing due east.GR® 101.
Leave the track on your left. A sign points to the Col d'Andorre. Another track then heads north-east, climbing upwards. It continues to climb, heading east. Pass the altitude 1190. Continue climbing.

(3) Fork in the road. The correct track ends. Head due east along a path that is flat at the start.GR®101. Leave the grassy track on your left. The path then climbs up into the mountain pasture. Continue for 400 m.

End of the markings.

(4) Slight fork at the entrance to the forest. Leave the red and white markedGR®101path which leads to a stream.
- Climb left, heading due north on the grassy spur. I have placed a few cairns to help you (October 2016).
- Just follow the cairns, staying on this spur, which is safe. The path is marked on the ground (animal trail). At around 1,430 m, go around the highest point on the right, following a path marked on the ground.
On your right, below, is the Cabane d'Andorre (marked but not named on the IGN map). The path heads north towards the Col d'Andorre.

(5) Just above the Col d'Andorre (altitude 1443), head due west, following a small animal trail that climbs up this new rocky and grassy spur. Follow these narrow paths, which are well marked on the ground. You will arrive above the forest.
Caution: you will be on the ridge path itself. Take extra care. Stay on this narrow path at all times. It is right on the ridge.

(6) Soum d'Andorre (1684 m). Beautiful 360° panorama. Continue to follow these narrow paths, which are clearly marked on the ground. Continue along this narrow ridge path, which climbs and descends, heading due west. You will arrive at a small, unnamed peak, altitude 1737 m. Descend a little, still following this narrow ridge path. Then climb back up into an open area, heading for what looks like a pass. The path heads slightly north-west for 30 m.

(7) Soum de Conques (1759 m). Beautiful 360° panorama. You will now need to follow the animal trails in this large summer pasture. Head southwest, leaving the few steep paths that descend steeply on your left. Then continue towards the Col de Las Escures (not named on the IGN map) where you will find a scrap metal enclosure and a more or less dry lake.

(8) At the pass, below the altitude 1654, head left towards the east, following the paths and tracks that descend steeply towards the forest. I have placed a few cairns (October 2016). Head south-east, aiming for a clear area with a wide track below.
Please note that the IGN map is not accurate in this area. Some tracks are not marked on the map. My route follows existing tracks throughout. I did not cut through the forest. You must follow this route.

(9) Join the track. I have placed a large cairn. Head left, due east on this track for about 200m. The forest is growing back in a haphazard manner. It is possible to cut some of the bends in the track by descending steeply via other open tracks. I have also placed a few cairns (October 2016). At around 1,250 m, you will find a steep track that has been opened up and allows you to descend by cutting across the track in several places. Continue descending due south.

(10) Open area with several tracks. Head left, due east, following a track. Join the morning track. Head right. The car park is visible on the left. Cross a fence. Close the gate behind you.

(1) Turn left and head towards the car park (S/E).

A beautiful hike that I enjoyed.
I didn't leave the trail at point 4 and continued on the GR, which I left a little further on when I reached the meadow leading to the pass (yellow markings). At point 5, I had great difficulty finding the path leading to the summit of Andorra... the vegetation had grown thick and after several attempts, I found a way through by going around to the right and entering the forest.
There is a cairn, but you have to find it, and the passage through the forest is a matter of guesswork...
Once you've got past this obstacle, you're treated to the magic of the ridge line. OK, so it was raining, but the sight of vultures, kites, crows and passerines in flight, and encounters with ibex and roe deer quickly made me forget the bad weather. Access to the small summit between Soum d'Andorre and Soum de Conques was also obstructed, and I had to descend into the forest to reach it (a tricky spot due to the steep slope).
The rest of the hike is as described.
700 difficult metres over 9 km... but it is essential to take this into account and proceed with caution.

I will return, when the sun is shining.
Time taken, including stops: 5 hours 30 minutes.

Hike done with two people. On the climb up to Soum d'Andorre, we missed the fork to the right and found ourselves on very exposed terrain. We turned back and, after finding the fork, the route was well marked all the way to Soum d'Andorre. After that, there were no more markings, but it was a classic ridge route. There was no difficulty in reaching Soum de Conques and then the pass that follows.
However, the big challenge for us was the descent down very steep slopes with very tall grass, no path, no cairns (except for a few at the very end) and only a brief description. Coming after an already demanding route, this descent really put us to the test.

A magnificent hike for those who enjoy beautiful landscapes and solitude. A very good sense of direction, a reliable map and GPS are essential. The description is very good and the route is perfectly reliable, with one small detail: around the 1296 m contour line, you have to search a little for the fork that allows you to descend to the next track.
As someone has already pointed out, there is no point looking for the cairns that the author placed in 2016: they have probably been destroyed by the elements or animals.
Thank you, lemarcheur65, for this guide!

A very beautiful hike with magnificent views of the Pau-Tarbes plain and the Pyrenean peaks from Pic du Midi de Bigorre to Gabizos. Well done to the author of this route. The climb to Soum d'Andorre and the crossing over the impressive ridge, which is safe if you stay on the north side, is a real treat. The few cairns (which we rebuilt a little) helped us a lot during the climb to Soum d'Andorre. The descent from the ridge, on the other hand, is a little difficult, or perhaps we didn't find the right path, but the perfect visibility and the route on the map took us directly to the entrance of the forest. JUST MAGNIFICENT.

Partially completed on 30/05/2021. The route was quiet that day: very foggy weather meant we had to give up on walking along the ridge (no visibility near Soum d'Andorre), returning via the same route we had taken up. What we did see suggests that this route is worth coming back to.
The first part of the guidebook (up to the Col d'Andorre) seemed a little (just a little!) imprecise to us.

This hike is magnificent!
You just need to be comfortable with heights because there are some slightly dizzying sections.
However, we got lost three times because we had to follow "well-marked trails" that weren't marked at all... There were few cairns despite the description saying there would be (were they removed? Did we miss them?). There was one section that we only found because some people who were clearly familiar with the area passed by and pointed us in the right direction... (the climb to the ridges). We even got lost on the way down (looking for the entrance to the forest where a large cairn should be waiting for us), even though it seemed straightforward... There are lots of paths on the mountainside, all fairly inconspicuous, so it's impossible to know which one is the right one... It's a shame. Perhaps we're not used to it and should probably have used the GPS earlier.

But it's worth going to the top, it's splendid!

When you reach the peaks of the Andorra Pass, the cairns are not always visible. And on the descent, I had a bit of trouble finding my way, I got a little lost but in the end I found the path again.

Very beautiful view. No problem going up, but the way down is harder to find.
