Sporty loop around the Aigoual

For experienced hikers, here is a 40 km loop starting from Valleraugue and reaching Aigoual via the famous 4,000 steps. It descends to Lac du Bonheur near Camprieu, then climbs back up to Espérou and ends along the ridges facing Mont Aigoual, which you will have discovered a few hours earlier.

This hike is not technically difficult but is very long with some steep sections and requires good stamina.

Description of the walk

Park in the hikers' car park in the village of Valleraugue.

(S/E) Cross the village heading north, quickly join and follow the Sentier des Quatre Mille Marches trail, marked in yellow. Stay on this trail for a long time to reach the Mont Aigoual weather station.

(1) Continue opposite downhill on the D118, which is also theGR®60and the Equestrian Route. You will reach a crossroads at the first bend.

(2) Turn left onto the trail towards the Prat Peyrot ski resort and follow it until you reach it.

(3) Cross the road and take the path that continues opposite, which is theGR®6shared with theGR®6A. Pass a path on the right, then another on the left, continuing westwards. You will reach the Col de la Caumette.

(4) Continue left on theGR®6. Stay on this trail to exit the forest and reach a grassy ridge that descends to Camprieu. Reach a house at a place called La Croix de Fer.

(5) Take the hairpin bend to the left to return towards Lac du Bonheur. After two bends, go around a group of houses on the right at a place called l'Aubespi.

(6) Take the path on the left towards the lake, joining it at theGR®62crossroads.

(7) Take the road on the left along the lake, follow the Ruisseau du Bonheur to reach the Baraque Vieille crossroads.

(8) Leave the track leading to the ruins of the Abbaye du Bonheur on your left and follow the path on the right to the Col de la Serreyrède, where you will find the Maison de l'Aigoual and a fountain where you can refill your water bottles.

(9) Cross the road heading south towards a house, then climb straight up to reach the Col de l'Espérou.

(10) Turn left to quickly reach the village of Espérou.

(11) At the Espérou roundabout, cross opposite towards the Hôtel du Parc, staying on the road that climbs between the houses (D548A). You will reach the forest shortly before the junction with the D548.

(12) Leave the road and take the path on the right that runs alongside the forest. This path is marked by severalGR® trails(7, 60, 66 and 71). Continue until you reach a junction where these GR® trails separate.

(13) Turn left to stay onGR® 7 and 60. Continue along the almost flat path to reach the Col de Montals.

(14) Leave theGR®7here and continue straight ahead on theGR®60towards the Col de la Lusette. Leave the track that leads to this pass on your left and stay on theGR® to join the D329.

(15) Take it on the right for about 300 metres and join the Drovers' Road crossroads.

(16) Turn right here to rejoin the D329 further ahead.

(17) Leave theGR®60here and turn left onto theGR®62C. Descend, staying on the ridge until you reach the crossroads serving a sheepfold.

(18) Turn left into the forest and take the path that descends to Valleraugue. You will then come to a fork where both paths lead to the village.

(19) Take the right-hand path, which is a little steep but more direct. Follow this path downhill and you will arrive directly at the hikers' car park in Valleraugue (S/E).

A very pleasant hike in autumn. Nature is decked out in its most beautiful colours.
After the legendary 4,000 steps, we arrive at Mont Aigoual station, which is quiet early in the morning. We head towards Camprieu and its lake of happiness, walking at a gentle pace with no major elevation changes.
And finally, a fairly technical descent, 1,000 metres over 5 kilometres... be careful with your joints. Better safe than sorry.
A quick hello to Mr Patou, master of the premises and protector of his sheep friends. With the right attitude, everything went well.

We had planned this hike over two days, but for our planned dates, there was no accommodation available in Camprieu or L'Espérou as they were closed for the season. So we decided to go ahead with it, but taking the Prat Perot - Camprieu route and returning via the Col de la Serreyrede, which meant we went directly from Aigoual to L'Esperou. In the end, it was a 28 km hike with 1,565 metres of elevation gain. Luckily, the weather was magnificent all day. The next day would have been difficult because rain was forecast. A magnificent hike, a little long at 10 hours in total, including lunch at the observatory and coffee at L'Esperou. Difficult, especially the last part, the descent on unstable rocks. Magnificent views of the Hérault valley.
We didn't meet anyone except tourists on the Aigoual. There were five of us, the youngest being 64.

A very good two-day route with an overnight stay at Lac du Bonheur (please note that camping around the lake is strictly prohibited in summer).
The route is very easy to follow with signposts from the FFRandonnée.
However, you need to be in good shape for the first day, which has an elevation gain of 1,250 metres, so it's not for everyone! But apart from that, it's a fantastic route!
We did it in early November and it was still very doable, but you need to be equipped for the cold at night, which lasts from 6 p.m. to 8 a.m.

Two-day trek completed in early October 2024. At the time of writing, the water source at Aigoual was dry (tap in a turret to the left of the steps marked "4001" when you arrive at the observatory). You can ask the Valleraugue tourist office if the restaurant is open at Mont Aigoual (it was open on that Saturday).
Those at Lac du Bonheur and the regional house were fine.
PLEASE NOTE: the lake is empty because the small dam is under construction.
on the first day, the climb is really beautiful, with stunning scenery. Shortly after the observatory, the forest path is less attractive, but it quickly becomes beautiful again on the small trails.
I pushed on to the regional house and pitched my tent behind the abandoned house opposite. You can hear the cars, but after 9 p.m. there is very little traffic. I met three very nice female trekkers who had booked a lodge in L'Espérou. They were right to do so because, unfortunately, on the second day, contrary to the forecast, it rained all night and all morning. I did the route anyway, but between the fog and the rain, it was quite an epic journey with quite a few minor falls that I felt coming on despite my very good shoes and firm support from my walking sticks.
Obviously, it's really not recommended to do this loop if the ground is wet.
Still, it was a beautiful trek, with patous in the fog and a fried country sausage when we arrived at midday in Valleraugue (farmers' market). A nice bonus instead of ending up eating a freeze-dried meal in the car!

Two-day circuit with bivouac around Lake Bonheur.

Watch out for sheep after Lake Bonheur. The GR trail passes through the middle of a farm and the shepherd lets his dogs get very close to hikers.

The first part has a very steep climb. The rest is easy going.

A very beautiful hike

A beautiful two-day hike
Camped near the Abbaye du Bonheur
Frequented on the 4,000 steps trail, but we didn't meet anyone else after Mont Aigoual
This hike is classified as very difficult, probably because of its length, but over two days it's very good, and no doubt also because of the beautiful descent to Valraugue

Hello,

I completed the loop this weekend in warm weather (29°C in Valleraugue). We set off at 12.30pm and arrived at Lac du Bonheur around 7.30pm to set up camp. It's a very pleasant area. The lake is currently empty (you can hear the pump), but once you move away, it's really quiet. Thanks for the comments and information about the toilet and water facilities.
The next day, we left at 9:30 a.m. and arrived around 6 p.m. in Valleraugue.
The last part (between point 18 and A) is quite difficult, especially with weight on your back and the 38 km you've already covered...
I also agree with the previous comments, it's a very beautiful loop with stunning scenery.

Hello,
Even if you do it in one day, this loop is best done over two days. Three days is probably a bit too much unless you leave late on the first day.
At this time of year, don't hesitate to set off early to climb the 4,000 steps in the cool morning air.
You'll need to save your legs for the last few kilometres of steep descent to Valleraugue.
Several previous hikers have camped by the lake. You can ask for confirmation at the town hall in Camprieu St Sauveur (Tel. 04 67 82 60 26 - Email: saint-sauveur-camprieu@orange.fr).
Enjoy your hike.

Hello,

Is the hike feasible in 3 days or can it easily be done in 2?
Is camping at Lac du Bonheur permitted?

Thank you very much

Superb hike on 27 and 28 May 2022 (two beautiful sunny days) with a bivouac at Lac du Bonheur. The climb up the 4,000 steps is magnificent but a little long, especially when you're carrying a heavy load (which I was... ), but not too steep. Between this climb and the final descent, it's pure bliss, with magnificent landscapes alternating between unobstructed views and wide, shaded paths. It's very easy to camp at Lac du Bonheur in a designated area on the other side of the lake.
There are toilets and water points in Valleraugue, at the observatory and at Lac du Bonheur (near the dam). There are also running water points (for those with a filter bottle) along the way.
It is mainly the descent to Valleraugue that makes this hike "very difficult". From the André Chamson monument to Valleraugue, there is about 6 km of rocky and sometimes difficult descent that really hurts your thighs and knees...
Apart from the 4,000 steps, I hardly met anyone.
Thanks to Klodeko for this hike and for the perfect GPX track.

We completed the loop over two days, spending the night at L'auberge du bonheur in Camprieu.
day 1: 20 km - 1,315 metres of elevation gain.
day 2: 25 km and 1,150 m elevation gain (more than expected in the description...)
A very pleasant route with varied landscapes. The ridge sections are superb. The 4,000-step climb is very busy, but once we got past that we were alone!
We recommend it!

Hike completed on 30/01

The route is really nice, the climb is long and a bit steep, but there are no major difficulties other than the elevation gain and the length. However, the ridges must be truly magnificent, and we weren't able to fully appreciate them because we started in the dark.
We decided to add a little loop to see the Bramabiau abyss (closed at this time of year). Total distance: 46.5 km, starting at 6 a.m. and finishing at 6 p.m., including meal breaks.

The sunrise 1 km from the summit was just perfect

Be careful with strong mistral winds, it's cold at the top of the Aigoual.

Thanks for the loop

The loop was completed under strong sunshine, which made it extremely difficult. Two poorly marked sections, but we quickly found our way. The descent is very tough. The lake is dangerous for swimming as algae clings to you when you swim. It is best to do this in spring. Thank you for the GPX track, which is very accurate.
