Description of the walk

On leaving Arrens-Marsous, follow the Lac d'Estaing road for 200 m. Park in the car park on the right.

Yellow and Red markings – GRP® Tour du Val d'Azun

(S/E) Follow the road for 100 m and take the footbridge on the left over the Gave d’Azun. Follow the track heading due east for about 100 m (arboretum sign). At the left-hand bend in this track, follow a path that climbs steeply (to the right) through the north-eastern forest for about 300 m. This path offers a chance to see a variety of tree species.

(1) Under the high-voltage power line, turn sharply right heading due south-west. After 200 m, the path reaches the D603.

(2) Cross it carefully and continue straight ahead along the path, heading south-east, then south-east. This path then climbs steeply, winding through the old mountain pastures. It then heads due south, passing close to a small stream overgrown with grass. After passing the stream, the path turns left, heading due north-east, and continues to climb. After a few bends, it reaches a ridge and turns sharply right, heading due south. Continue due south for about 300 m.

(3) Cross the low stone wall. Take a pretty path lined with low walls which descends to the left, heading due east. After about 300 m, you’ll reach a fork.

(4) Take the path that climbs slightly to the right, heading due south-east. It soon turns due south. Follow this south-easterly path up to an altitude of around 1,487 m. The path runs more or less along the hillside, staying within the cirque. It then turns due east and reaches a ruined hut.

(5) Turn sharply south and follow the path downwards. It turns eastwards to reach a gate.

(6) Go through it and descend via the south-easterly path, which turns west. Soon the path turns south-southeast, crossing the Ruisseau des Boussus several times. Continue the descent along a wide track, cross the Pont de Miaous over the Gave d'Estaing and join the D103.

Red and white markings – GR®10

(7) Follow the road carefully for about 500 m, keeping to the left on the hard shoulder. Turn left and cross another bridge (marked ‘private property’).

(8) Immediately after this bridge, turn right. Do not go through the gate on your right, but follow the path along the Gave. Very soon, this path runs alongside a campsite. At the campsite entrance, take the road on the right and cross the Gave again.

(9) Do not follow the road. There is a wide path running alongside it. Follow this path for about 500 m. When you reach a road, turn left and follow this road to a new bridge over the Gave.

(10) Cross the Gave and the D103 road with care. Take the path opposite the bridge. This path climbs and turns right, heading due north. After 250 m, the path turns left. Go round the church and follow the edge of the cemetery. When you reach a road, turn left and follow this road heading south-west for about 500 m.

(11) A path branches off to the right, heading due north. After 60 m, turn left and follow a stony path (due west) which crosses the D603 road, and follow it for 300 m. You will need to leave the road at a right-hand bend.

(12) Follow the stony track heading left, north-west. This track joins the road. Follow this road for 100 m, then leave it at a right-hand bend to climb into the woods and overlook the road. After 600 m, this track joins the road (start of the route to Pic De Pan).

(13) Follow the D603 road carefully for about 1 km. Leave it at a left-hand bend to cut across the hairpin bends of this road and rejoin it at another left-hand bend.

(14) Two options:
- Follow the D603 again for 600 m, turn sharply right at the arboretum and turn left until you reach the original junction.
- Head down to the right and join the path through the arboretum, then continue straight on to the original junction.

(1) Return to the fork from the outward journey. Head back down opposite towards the track, the footbridge and the car park (S/E).

Notes

Remember to bring water, rainwear or a windbreaker if necessary. Drinking water is available at the campsite.
This route is rugged and requires good walking (hiking) boots.
There are sections of road. A quick reminder: if there are one or two of you, keep to the left-hand side of the road facing oncoming traffic. If in a group, it is advisable to walk in the same direction as the traffic, following one behind the other in single file. In any case, the main rule is to stay on the hard shoulder and stop when two vehicles pass each other.
If the ground is muddy, on the return journey do not go down into the arboretum. It is better to follow the road and return to the morning’s starting point.
=> Following a comment from a user on 21 May 2026: I would like to point out that from (S/E) to (7) it is the GRP® Tour du Val d'Azun, and from (7) to (S/E) it is the GR®10. Subject to subsequent changes to the route of these marked trails.

Worth a visit

In Arrens-Marsous there is accommodation, a variety of activities, places to eat, and shops selling local produce.
There are plenty of photo opportunities along the route.
It is the sort of route that gives you an appreciation of the titanic work carried out by our ancestors. They had to provide for their own food needs in these rugged areas of the Pyrenean mountains.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

Hello Le Marcheur 65,
Given your 40 years’ experience at the FFR, including trail marking, you are well aware that the marking and therefore the route of the GR (Grande Randonnée) and GRP (Grande Randonnée de Pays) trails, managed by the FFR, is fairly stable. Indeed, several comments mention that the markings have helped them. So let’s not pretend that the signposting doesn’t exist. Any changes to the route and signposting of GRP and GR trails occur in the event of temporary or permanent disruptions (numerous fallen trees, landslides, boundary disputes). So it’s fair to say that the signposting on the GR and GRP trails is more up to date than any written description. As for the signposting and route of the GRP between Arrens-Marsous and Estaing, it was altered when the track leading from the livestock enclosure at the Col de la Courbe was opened in 2019 (Point 5 on your map). We had noticed that walkers were no longer using the route via the barn (Points 6 and 7) and were taking the new farm track. Without wishing to argue, I note that the VisoRando description has not been updated since 2019. This speaks volumes about the trust one can place in the GR and GRP routes.

Hello ours65
When you were asked to give your opinion, it said:
=> Visorando focuses on guiding hikers using a route description and an IGN map extract rather than relying on signposting, over which it has no control. When answering this questionnaire, please therefore concentrate your comments on the quality of the description and the route, without mentioning the signposting.

As for your comments on the FFRandonnée, I have read and understood them. For my part, I have led and accompanied hikers for 40 years using my federation map. I have marked out trails, cleared paths and maintained huts, etc. So...

It would have been clearer and more honest to specify that, from Arrens to the village of Estaing, the route described follows the Val d'Azun GRP (Grande Randonnée de Pays), marked in "yellow and red", and that from the point where the Gave is crossed (Point 8) onwards, it follows the GR10 (Grande Randonnée), marked in "white and red". Normally, even without a route description, you can find your way by following the markings. The markings are maintained by volunteers from the FFR (Fédération Française de Randonnée), which is responsible for marking GR and GRP trails in France. I maintained the markings between Arrens and Estaing for several years. It is worth noting that the FFR also publishes guidebooks describing GR, GRP and PR (Promenade et Randonnées) trails. Moreover, these PR trails are very often developed by local councils or inter-municipal bodies with the help of the FFR.
Thank you to Visorando for ensuring that proposed contributions make a point of noting, where applicable, that the descriptions specify whether the route is a GR or a GRP, thereby recognising the work of the FFR and the volunteers who maintain the signposting.

I can confirm that the climb is steep from the start, but the descent along the path (road!) is really not pleasant. Apart from this downside, the landscapes are varied and there are lots of water sources. It was great for my dog, who was able to swim in the river during our lunch break and cool off when needed. I did this hike on a cloudless, very hot day. Three-quarters of it is in the shade and very well marked, which is perfect! Apart from sheep and horses, I didn't meet anyone...

Hello,
I have just completed this route, with several new features.
Firstly, I am using "My Trail" software on my mobile phone. According to this software, the hike is 16.3 km long with a cumulative elevation gain of 1,036 m. That's a bit of a change.
Secondly, the agricultural community is modifying the GR de Pays trail. The track that descends to the Gave d'Estaing and the D104 is being widened by bulldozers and excavators. This has resulted in the loss of the bucolic charm of this descent. For the moment, the track is a steep motorway for tracked vehicles. Watch your thighs!
Otherwise, it's a great walk with a lively start, to say the least. The variety of landscapes is most enjoyable. And if you have to walk a bit, it's more than compensated for by the pleasant passages.
Thank you for this ride

A very beautiful, fairly challenging hike between points 3 and 5. Work is currently underway between 8 and 9. A very wide track (for 4x4 access) is being built, which made the descent very tough on my thighs! (I'm approaching 75...). In fact, the widening of the path with a steep gradient makes the descent quite difficult.
A day that I will treasure among my fond memories

superb hike, with panoramic views of our beautiful Pyrenees, varied terrain including fairly steep paths, paths through the undergrowth, open paths exposed to the sun, very few roads, paths running alongside streams and the mountain river. However, I should point out that there are a lot of ticks and horseflies between numbers 3 and 8.
we completed it in about 6 hours and 15 minutes, with a little difficulty finding the markers around kilometres 9 and 10.
we really enjoyed the panoramic views and the sea of clouds around AUCUN and MARSSOUS.
a few passages along the streams are a great way to cool off!
Thank you for this route.

Great hike! Very easy access, beautiful route, good mix of flat sections and sections with steeper gradients. Recommended for the first day of a multi-day route. A great way to warm up.

we begin with a fairly steep climb from Arrens-Marsous.
The weather is a bit cloudy, but the mountain reveals itself from time to time and we take some beautiful photos. The Pic d'Arrens and its cloud scarf.
The church in Estaing. Well-maintained huts with water running underneath them, probably for storing cheese.
We climb back up to the Col des Bordères along a stream that rushes down from rock to rock.
Return via the arboretum and a little further down to the car park.
A real treat.
