Between forests and ditches, in the footsteps of P.P. Riquet

On the watershed between the Aude and Tarn rivers, we follow in the footsteps of P.P. Riquet once again, discovering other water resources that enabled this self-taught engineer to demonstrate to the experts sent by Colbert the merits of his project to supply his Canal des Deux Mers. However, the forest remains present on this easy route, and Arfons, with its slate roofs, is a picturesque little village in the Haut-Languedoc Regional Nature Park.

Description of the walk

Park along the D4 in the hamlet of Lampy Vieux, respecting the service lanes.

GR® 7 markings (white and red)

(S/E) Take theGR® 7 to the left of the D4 (towards Saissac) on a path closed to traffic (barrier). Follow the Rigole de la Montagne to the Bassin du Lampy Neuf, created to meet additional water needs during the construction of the Canal de la Robine.

(1) Turn right to cross the retaining dyke and follow the contours of the basin northwards. Cross the Lampiot and reach a fork in the path

No more markings

(2) Leave theGR® 7 by turning left when it branches off to the south-east towards a place called Lampiot.

Cross the Lampy via a ford. Ignore two branches to the left before following the Aude-Tarn border for a few metres. At the fork, turn right.

(4) You will come to another intersection (elevation 660). Keep to the right and cross the Bengue de Martel towards the north, following the right bank of the Lampy. Join a track (elevation 681)

GR® 7 markings (white and red)

(5) Turn left and follow theGR® 7, which runs alongside the track before rejoining it below Terme de Roquecave. Leave it at a right-angle bend to stay on the GR®. Turn north-west and arrive at a new crossroads.

(6) Go straight north and then, after Cantemaraud, descend to the left via the direct path towards the Galaube road. Cross it to continue down the Sarotte slope and come out onto the D12 at Pont de Larroque.

(7) Cross the Sor and head towards the village of Arfons via the Lampy road, leaving the Fontaine des Canons path on your right (cross).

No markings

(8) At Place du Plo du Barbier, leave the GR® 7, which branches off to the right, and stay on the D12 towards Sorèze. Continue to Place du Poids Public. Turn left onto Chemin de Phalippou. At the end of the tarmac road, after crossing the Aiguebelle stream, follow it for a short while on a path that then turns westwards and climbs uphill. Ignore a fork to the left and you will come out onto the small Bastouls road.

(9) Turn left and descend this carriage road to the Planque Haute hunters' hut. (Photo)

(10) Stay on this good track, which slopes gently down through the Sarremégé Forest. Once out in the open, continue down the winding dirt track until you reach the signposted Lac des Cammazes trail at a place called La Forge.

Yellow rectangle markings

(11) Turn left, cross the Sor via a concrete bridge, then follow the widening of the stream via the dam on the opposite side and turn left at the three-way junction to climb up to the Conquet spillway.

GR® 7 markings (white and red)

(12) Then stroll along the Rigole, following the GR® 7 eastwards. After crossing the small Col de l'Alquier via a deep trench, clearly dug by hand to level the Rigole, you will come out onto the suspended plain of Le Conquet, where the aptly named Rieutort stream meanders.

(13) Here you will find a second spillway used to empty the channel when maintenance is required. Then follow the western edge of this wide basin at the edge of the steeper slopes of the valley downstream, then follow the northern slope of a hillock that borders this plain to the south. After a right-angle turn, head due south, crossing another pass via a trench that is even longer and more steep-sided than the first. Now head due east, following the twists and turns of the valleys carved into the mountain by streams. Cross two more ridges that stand out from the massif via two small passes, one through a short, shallow trench and the last at level ground. Join the D4.

(14) Walk a few metres to the right on the road to return to the starting point (S/E)

Notes

(10) Hunters' hut for a possible stop (picnic) (photo)

Warning: this route has been modified due to the crossing of private property, despite verbal permission to pass! From now on, follow theGR® 7 from the hamlet of Lampy Vieux (anti-clockwise)

Worth a visit

(S/E) Here, Vauban, in order to improve Riquet's system, had a first dam built, which preceded the current structure located a little higher up on the same river by a century.
Before setting off, note (on the right-hand side of the road towards Arfons) the current Lampy Vieux aqueduct, which crosses the stream of the same name.
(12) The Conquet spillway was a key element in the Canal du Midi's water supply system in its early days. It was the location chosen by Riquet as the outlet for his Rigole de la Montagne in the Sor basin. Six years after Riquet's death, Vauban extended this canal between Le Conquet and Les Cammazes, where he had the famous arch bearing his name built.
Stop briefly near the guard house to discover these features on the Rigole, the spillway and the weir.

Nearby (by car):
Head to the village of Les Cammazes to discover the Vauban arch.

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.

There are significant differences between the written description and the GPS track, which require the ability to read a map and interpret the landscape.
In addition, part of the path was damaged by forestry machinery, but fortunately the ground was frozen
Beautiful frosty forest!

Hike through a frost-covered forest at minus two degrees, very beautiful
Downside: lots of wide tracks, few narrow single tracks, but also little tarmac.

A very nice hike, very accessible and easy (no climbs)
In the forest along Lake Lampy: it's very pleasant with beautiful trees
but there are lots of paths and there are hardly any signposts
so we took another path, which was just as well because we stopped for lunch with a beautiful view of the lake!
After the village of Arfons... a long, open track, a bit tedious, to get back to the GR along the Rigole, which is well shaded and very pleasant because it was a sunny day and 30°C
😉!

A beautiful hike through forests with a variety of tree species and water features such as fording streams, overlooking Lake Lampy, discovering the works of P.P. Riquer to master this element, which here can flow very peacefully and suddenly in dazzling waterfalls. The March showers, alternating between snow, rain, hail and sunshine, added to the excitement of this beautiful hike.

An easy hike between the canal and the forests of the Montagne Noire. In autumn, the yellow and orange colours of the trees are magnified by their reflection in the waters of Pierre Paul Riquet's canal. We admired the many varieties of trees in the forests: beech, conifer, chestnut, oak, birch... and enjoyed a wonderful mushroom hunt as a bonus.
The two lakes, Lampy and Cammazes, are well worth a visit.
Best enjoyed on a sunny day.

This walk follows routes from other walks we already knew, but combining them in this way is nice,
especially the end along the canal.
We had already gathered enough chestnuts to make ten jars of chestnut cream. What a shame!
Well done for the idea!

Hello, everyone. Here is a superb hike, in the dappled shade of half-century-old Douglas firs and century-old beeches. The section along the stream is magnificent (GR 7). At the end of the hike, we extended it by taking the section of the GR7 below Arfons. Magnificent
Thank you, Visorando. petitbob.

We chose this hike because of the scorching temperatures in May and because it seemed to be mostly in the shade: we weren't disappointed and were actually quite glad we had planned to wear long sleeves to start with! Between the altitude, the light breeze, the proximity to water (stream, lake...) and the route mainly through forest, it was perfect! this hike is really very pleasant, never monotonous, the undergrowth is varied with many different species of trees, the path is easy with little elevation gain and with a picnic break, the 17 km are "devoured" without any real difficulty. Be careful not to lose sight of the map, as you will come across many other paths and you need to stay alert to avoid having to turn back!
We enjoyed admiring all the flowers along the route and the expanses of broom in full bloom. We even saw a wild boar fall into the ditch while trying to run away too quickly and swim back up a few dozen metres before managing to get out!

Hike taken during a windy week with a cool Cers wind, so I didn't meet anyone, under an ash-coloured sky dotted with white. Perfect for magnifying the contrast of these spring greens, beech, Douglas fir, oak, chestnut and fern trees illuminated by the warm yellows of flowering broom. And the smell of that broom...
A very pleasant walk under the canopy of the forests we crossed, with a snack at the Planque Haute refuge, which remains open to hikers on non-hunting days (Wednesdays, Saturdays, Sundays and public holidays).
We could have enjoyed it as it wasn't hot, with chairs and tables available, but despite the notice at the entrance, no one had left any matches to light a fire in the fireplace. Keep that in mind.
Four hours and twenty minutes of leisurely walking, a beautiful walk that we extended by 2.5 km by passing through the north of the Lampy basin.
Thank you for this suggestion.

An easy hike. You can also start from Arfons, which allows you to enjoy the beautiful setting of Lake Lampy for a picnic. There are many conifers below Arfons, which is a bit of a shame as the ONF (French National Forestry Office) mainly reforests with this species. There is a lovely shaded section along the stream on the GR7 to Lampy Vieux. There is a beautiful beech forest above Lampy on the way up to Arfons.

Hike with a group of 11 people, starting at the Lampy basin in the rain for the first hour. After Lampiot, we followed a forest trail that led us to the GR, which had been badly damaged by recent rains. The rest of the hike presented no further difficulties. We had lunch at the refuge halfway through the hike. The main interest for the group was discovering the mountain channel after visiting the "reservoir" at St Ferreol the day before. We also saw the various spillways.

A very pleasant and enjoyable hike, even on a grey and damp day.
No significant elevation gain, so very accessible.
Can be done in summer in hot weather, but that wasn't the case for us!
One small downside, which isn't really a downside... the bucolic lyricism of the descriptions made us lose track, but luckily we had an IGN map of the area... but as we had a good laugh reciting the text, we'll forgive them!
