The Col de Joux

The Col de Joux is the only crossing point between the Ariège and Orgeix valleys. This mid-mountain route starts in open terrain and then enters the Ax-les-Thermes communal forest. The ridge passages offer beautiful views of the surrounding peaks, the most iconic of which is undoubtedly the Dent d'Orlu, whose south face is clearly visible. Herds of cows and horses complete the picture.

Description of the walk

Coming from Ax-les-Thermes on the N20, just after crossing the bridge over the Ruisseau du Nabre, turn left - take care as the road is very busy - into a small street following the sign for "Église romane" (Romanesque church). Cross the metal bridge over the Nabre and then turn immediately right. Pass the church in Mérens, driving carefully as the road is very narrow in places. Continue to the car park just below the church in Vives, a magnificent Romanesque building of which, unfortunately, only the bell tower remains intact.

(S/E) Return to the small road you came up on.

White and red GR® markings + directional signs

Turn right to go around the church, then turn right again at the corner of the boundary wall. Cross the road and go straight up, first taking a tarmac road and then a wide stony path that cuts across two bends. Join the road one last time at a bridge on the right and a wash house on the left.

(1) Do not cross the bridge, but take the small tarmac road (Rue de Saint-Touret) almost opposite. This quickly gives way to a wide path that climbs fairly steeply and steadily along the Ruisseau de Saint-Touret.

(2) At a weir (crossroads with directional signs), take a sharp left turn following the signs for "Col de Joux - Orgeix - Orlu". Keep heading north-west, pass under a fallen tree across the path (situation in September 2019) and reach a metal gate.

Go through it and make a sharp right turn. Continue climbing to pass the moving ruins of Saint-Touret and then the barns of Coual.

(3) Shortly after a spring that you can hear murmuring on your right, ignore the track that levels out on the left and continue climbing straight ahead to reach the Llata-Larguis forest road at the edge of the forest (direction signs).

(4) Turn right to follow this track, which further on makes a sharp left turn and then reaches a pretty clearing just before another sharp turn. Ignore the track on the left.

(5) At the bend, leave the track you have been following and take the wide grassy path opposite, which leads into a magnificent spruce forest. Cross the electric fence that bars the entrance to a large open space (Sarrat de Larguès) and continue along the ridge with a beautiful view of the Orgeix valley and the Pic des Estagnols on your right.

Then climb up to Cap du Camp (IGN route incorrect here) and descend to Col de Joux, a large grassy clearing with a shepherd's shelter above. Head for the signpost.

Yellow PR® markings + directional signs

(6) Leave the GR® and head left (west) into the meadow, following the sign for "Petches - Ax-les-Thermes". The buildings of the Bonascre - Les Trois Domaines ski resort are in sight. At the break in the slope, look for the wooden post with the yellow signpost, followed by several others that indicate the path to the forest entrance. You will soon reach a fork (directional signs).

(7) Turn left, following the signs for "Ax par Courtal-Juan". After a section that can be very muddy after heavy rain, the path widens and descends gently to the small Courtal-Jouan forest refuge, where there is a picnic table. Continue downhill to the forest road.

(8) Turn right and continue to a large multiple crossroads (signpost on the left).

(9) Leave the uphill track on your right and the one you have just followed opposite. Take the path that starts on the left, following the sign for "Couillet de Bergon - Mérens".

At Couillet de Bergon, the junction shown on the IGN map no longer exists on the ground. Continue along the path and keep going down the gentle slope.

(10) Be careful at this junction, which is not shown on the map and is not marked on the ground (I have placed a cairn). Turn right onto a narrow path that begins a very steep descent into the Bois de la Soulanette. After several hairpin bends, the path levels out before leading to a grassy track (direction sign).

Continue straight ahead on this track, which becomes partially paved before reaching the Croix de Larguis, a small iron cross located on a rocky promontory offering a beautiful view of Mérens-les-Vals and the upper Ariège valley.

(11) Do not continue along what has now become a small tarmac road, but turn left onto a narrow, barely visible path that starts at the foot of a signpost. This path, which is quite cluttered and stony, follows the contour line almost exactly until it joins the road at the Romanesque church of Vives, where you will find the car park where you started (S/E).

Notes

This hike is classified as moderate, but you will need to make a constant and sustained effort between (1) and (4) as the slope is steep and offers little respite.
Similarly, caution is required after (10). The path is narrow and very steep. The drop in altitude is sudden. Walking poles will be very useful to relieve pressure on the joints.

High-top hiking boots are recommended.

There is a spring on the right-hand side of the path after the Coual barns and shortly before (3). It is difficult to access and the water has not been tested for potability.

The route crosses several gates and electric fences, which must be carefully closed after passing through.

There were no cattle on the circuit on the day this hike was completed, but this is an area where they are present. Follow the usual rules in such cases, i.e. avoid sudden movements and proceed by going around them.

After reading the reviews, I was expecting a more satisfying hike. Admittedly, the Romanesque chapel is beautiful and the view from Sarrat de Larguès and Cap de Camp is worth stopping for. Otherwise, the climb is tough and there is no shade. The Col de Joux after the previous stop is disappointing – although it must be nicer when the yellow gentians are in bloom. As for the descent, which is shady and offers almost no views of the landscape, its only merit is that it takes you back to the car park.
It is difficult to find your way from the pass, even if you are heading for Bonascre. At 10, the path is visible but difficult to follow and hidden under dead leaves.

Very beautiful hike, 70% of which is partly shaded, which is nice when it's very hot. However, be careful at point 6, as the yellow wooden signpost is small and difficult to see. Then after point 7, the slope is quite slippery and should not be attempted in wet weather. Otherwise, a very beautiful hike.

Very beautiful hike. No problems with the trail. If you don't have the trail, be careful at Col de Joux because the perpendicular path is very poorly marked. Thank you to whoever posted this hike

A pleasant hike with lovely views on the way up, before the Col de Joux, and on the way down into the valley.
We encountered a curious cow at the Col de Joux who wanted to share our picnic, and saw a magnificent chamois in the forest.
The only slightly tricky part is just after the Col de Joux, where you really need to set off at right angles to the signpost.

The first part to the Col de Joux is very pleasant with beautiful views. At point 6, the yellow post is just a short stake. The return through the forest is a bit monotonous. Otherwise, it's a beautiful hike.

A very accessible and well-shaded circuit, alternating between flat sections and steep hills, completed by three generations, including a highly motivated 8-year-old child.

A lovely walk with beautiful scenery, just as promised!
Finding the car park is actually easy: just follow the signs for "Eglise romane" (Romanesque church) to the car park at the foot of the beautiful ruined church
At point 10, the yellow markings indicating that you need to turn have been deliberately erased (March 2022)
Fortunately, we had the instructions and the GPS route!
Lunch break at the Col de Joux hut with a magnificent view

A very beautiful hike offering unobstructed views of the surrounding valleys. The return route is poorly marked, so be careful not to take a wrong turn when you reach the pass (direct descent, no markings). After that, the markings are not always reliable, so bring a GPS with you or return by the same route.

I gave the route a medium rating for reliability because we couldn't find marker 7 (although I did find the yellow marker), which added more than an hour to our hike. This was the first time I had done this route as a loop; I usually retrace my steps.
Next time, I'll descend a little further below the refuge in the direction of the AX BONASCRE station, as I must have missed another marker.
Otherwise, it's always a pleasant hike in summer or winter, and the refuge is always welcoming for a good snack. I forgot to mention the only downside: the felling of fir trees by foresters , which spoils such a beautiful site...

We did this circuit in reverse to enjoy a climb through the shaded forest.
We finished it with a visit to the sulphurous springs.

There was snow from the start. No tracks from point 4 of the description.
A magnificent hike with beautiful views. The outward journey is much more enjoyable than the return.
Total time: 5 hours and 15 minutes, including photo breaks and a picnic.

A very beautiful hike that can be completed at a leisurely pace (with a nice picnic break) in less time than indicated. The climb is steep at the start but steady. The trail is very pretty and dotted with a few Mérens horses. The ridge at the edge of the forest (after point 5) was slightly snow-covered but perfectly passable without snowshoes and, above all, offered magnificent views of the surrounding snow-capped peaks, almost 360 degrees, before reaching the Col de Joux. There are a few slightly steep sections in the forest on the way down. Be careful not to take the wrong path when leaving the Col de Joux and follow the yellow markings on the wooden posts towards the west.
You can visit the sulphurous water springs at Mérens (about 15 minutes from the car park at the start), but they are very busy.
