Description of the walk

(S/E) From the Pla de las Peyres car park, follow the sign for the Refuge du Ruhle, heading due south. Continue along this path and stay on it.

(1) At the first junction, follow the sign for “Étangs de Fontargente” to the right and ignore the sign for the Refuge du Ruhle from here on. Follow the stream on your right until you reach a metal footbridge.

(2) Cross the footbridge, then continue straight ahead (slightly to the right), ignoring the path on the left. Continue through the heather along this single path, which then turns 90° to the left.

(3) Start the climb. The Refuge du Ruhle is now visible high up on the left. Continue along this path and you will first reach the largest of the three ponds.

(4) To return to the car park, continue along the same path, which veers to the right and takes you past the second and then the third pond.

(5) Go round the third pond on the right and start the descent. There are several sections of scree and hairpin bends, posing no particular risk, but do remain vigilant. Continue along this single path, which takes you back onto flat ground, to a wooden footbridge that had completely collapsed on the day of our visit but still allows you to cross the stream without getting wet (it remains to be seen whether it will be repaired or left to rot).

(6) Turn right and follow the stream on your right to the car park. Cross one final footbridge and you will arrive at the Pla de las Peyres car park (S/E).

Notes

Access: From Foix, take the N20 towards Tarascon, Ussat-Les Bains. Before Les Cabannes, turn right towards Aston. After Aston, follow signs for the Refuge du Rulhe. Pass the Riète dam, then the dam and the Étang de Laparan. Continue along a road in poor condition but still passable in a standard car if driven slowly (or very slowly in places) to the Pla de Las Peyres car park (end of the road). For our part, we parked just after the Laparan dam, as the road is in very poor condition in some places. We then walked the last few kilometres to reach the start of the hike.
20 km between Aston and the start of the hike.

Signposting is very clear: signs and yellow markings. No or very little mobile phone coverage on this circular route.

The actual duration is around 4 hours.

You can alter this route by going via the Refuge du Ruhle (magnificent and what an atmosphere!) or via the GRT from the Etang de Laparan.

Worth a visit

Once you've reached the ponds, you can head due south to climb the Col de Fontargente, which also marks the border with Andorra.

A very beautiful site and a lovely walk, though you do need to be very careful when crossing the numerous scree slopes on the way back.
The footbridge on the return route no longer exists, though this wasn’t a problem for crossing the stream, as the flow isn’t at its peak following this scorching summer...
The yellow markings could do with a refresh, but the path is fairly obvious.
Ultimately, the tricky bit of this walk is the access road from Aston: it takes an hour to cover 20 km, with some very tricky junctions and a car park that’s packed by 10.00 am (there must have been quite a few people at the Rhule refuge on the night of 19 September).

A lovely walk. Access is via a road suitable for cars, although there are a few ruts. Please note that the car park is small. The superb scenery makes the steep climb well worth it.

When I turned back at point 5, my Samsung Galaxy Watch Ultra 2025 recorded a round trip of 16 km, whilst Visorando estimated the route at just 12 km.
This walk was truly magical – I loved it, even though I didn’t make it all the way to the end so that I’d still have some battery left for a longer hike tomorrow.
Thank you for sharing this.

Hello, this walk is really interesting, but the estimated time seems a bit tight to me, as it took us about 4 hours instead of the 3 hours 35 minutes mentioned (though it’s true that at 74, we don’t climb as quickly).
Although the road leading to the car park is long, it is narrow and in fairly good condition, apart from a few potholes here and there.

Hike completed on 23 May 2026; the aim was to do the full 20km loop, but there was too much snow to continue.
We climbed up to the ponds via the return route (doing the circular route in reverse); the outward journey was at night, making it very difficult to see the path, but on the way back it was clearly visible so no major issues. The path is not particularly difficult (except at night), with quite a few passable snowfields and sections through scree to avoid some of the snowfields. If you don’t want to walk through the snow, I recommend doing the out-and-back route (so not the circular route) and in the direction shown on the map.
It took us 2 hours 30 minutes to climb at night and 1 hour 15 minutes to descend.
Enjoy the hike.

A lovely walk in mild weather. Well signposted and ideal for getting back into walking.

A superb hike, the start is quite steep but the reward is at the end of the climb: lakes and magnificent landscapes.
The descent is fairly easy and much gentler. At the end, a herd of wild horses was waiting for us.
The path is well marked and the app provides accurate tracking.
The car park is a bit small, so it's best to arrive early, especially as the upper part of the car park is accessed via an unpaved road which, when we visited, was riddled with large potholes, making it impossible to access without a 4x4.

Very pleasant hike, but steep throughout the first part.
The lakes are very beautiful.
Parking area too small

A beautiful route to enjoy with the family. There are a few rocky sections where you need to be careful when going up and down.
It's a popular spot, and the car park at the start was too small on the day we went, which meant we had to park further down the access road, like many others.

Lots of people in the large motorhome car park who don't know how to park properly. Very beautiful hike with magnificent views throughout the walk. About two hours of climbing on a fairly steep slope. Very beautiful landscape with magnificent ponds. The return trip (doing the loop) was less interesting and rather challenging on the scree, which required watching where you put your feet. It was tiring at the end, but the weather was great!
