The Gailhousty spillway

This two- to three-hour walk takes you to the Gailhousty site, where you can discover a number of structures of great architectural quality. Their function is linked to the danger of flooding from the River Aude, which has always been a threat. This part of the Canal de Jonction was built in the river's floodplain. The floods of 1999 prompted decision-makers to build the dykes that are part of the scenery along this route.

Description of the walk

Access: reach Cuxac-d'Aude from Narbonne. After the bridge over the river, turn left into Rue du Château d'eau towards the car park and take the street on the left that leads to it.

(S/E) At the end of the car park, find a path to climb up onto the dyke.

(1) Take the path that descends on the other side. Walk westwards, between the Aude and the embankment. Approach the road to Sallèles d'Aude.

(2) Continue as close as possible to the Aude, under the dyke supporting the cycle path.

(3) Avoid the D118 by entering the Bois de la Bourgade, where a fitness trail has been created. Follow the curve of the river and approach the Bize-Minervois railway line, which is used solely for transporting goods for local businesses.
Avoid the cycle path on the right and follow the railway embankment.

(4) Pass under the Eiffel-type bridge and turn right to reach the Gailhousty site on the Canal de Jonction, which connects the Canal du Midi to the Aude.

(5) Take the time to visit the surrounding area (double lock, spillway, dry dock) (see the chapter: practical information) before setting off again under the dyke on the left bank of the canal towards Sallèles d'Aude. Walk along the vineyards for 400 m before reaching a crossing.

(6) Turn right and go under the railway line. Continue along the path between the vineyards, approaching the Canal d'Atterrissement de l'Étang de Capestang. At the corner of a plot, continue between the vineyard and the ditch until you reach the road, which crosses it via a bridge.

(7) At the end of the bridge, turn left onto the path running parallel to the canal for 800 metres until you reach an imposing ruin.

(8) Turn right onto Chemin de la Bourgade and join the access road to the Epadh, "le Château de la Bourgade". Leave the retirement home on your right and head towards the Sainte-Catherine dyke, which was built after the 1999 floods to protect the village. Walk along the dyke to the D118, then cross it carefully to reach the embankment of another protective structure on the banks of the Aude.

(9) Climb the embankment to reach the cycle path that has been built there. Away from the traffic, turn left to reach a crossroads you passed on the way out.

(2) Continue along the cycle path and return to the initial fork.

(1) Find the path back to the car park (S/E).

Notes

Gailhousty site: picnic tables in the Bois de la Nation. You can explore the confluence of the canal and the Aude river and discover Sallèles d'Aude via the old road from Sallèles to Narbonne, which is a change from the long, straight and languid line along the canal.

Worth a visit

The Gailhousty site is located at the downstream outlet of the Canal de Jonction on the River Aude. The Canal de Jonction, which came into service in 1787, connects the Canal du Midi and the Canal de la Robine de Narbonne. Consisting of a lock, a spillway, a bridge and a dry dock, Gailhousty is one of the canal's most iconic sites. (source)
The spillway
The spillway is impressive in size, with fifteen sluice gates used to capture the floodwaters of the Aude diverted by the Gailhousty curve. At the rear of the building, at the foot of five arched openings, there is an 8 km long silting canal called "La saignée" leading to the Capestang Lake. Originally, it was planned that these waters, laden with fertile silt, would be directed there to fill it up and promote crop growth. Begun in 1776, work on this unique architectural ensemble on the Canal du Midi was halted during the Revolution.

To visit near Sallèles: Amphoralis, museum of Gallo-Roman potters (site)

Apart from the history of the Cuxac dykes and the Canal du Midi, this route is of little interest to hikers.
The return journey in particular is long and tedious.

The first part along the river is pleasant until you reach the spillway, which is worth seeing. After that, we went to the left of the dyke instead of the right, which meant we ended up in the village before turning back to find the right route. The return journey is less pleasant. Thank you anyway for the hike.

In spring, a beautiful walk among the flowers. The site of Gailhousty is very interesting.
Problem: between 2 and 4, we didn't really understand the route. You can't enter the Bourgade woods because the paths are invisible under the tall grass, the fitness trail is non-existent, and you can't walk along the railway embankment because the track crosses the Aude river at this point. In short, we are obliged to always take the path in the hollow under the cycle path, which seems to us to be the easiest and most logical option.

It is a very easy hike of over 9 km with nothing to see except the spillway, which is magnificent. It is ideal for getting back into walking.

Boring hike!!! It's a shame because the waterfall is magnificent, but that's not enough.
