Description of the route

From Gruissan, we drive to the Mandirac lock to avoid the D32, which connects Gruissan to Narbonne and is very busy. Parking is available next to the lock.

(S/E) From the Mandirac lock, we take the path along the Robine canal.

(1) We pass the Petit Tournebelle estate (lodge). The strip of land narrows between the Campignol and Bages lakes, but it is further on, towards the Ayrolle lake, that the passage is narrowest. We share this space with the railway line.

(2) We pass the Ardillon roadmender's house (in ruins). A bend in the road brings us within sight of Île Sainte-Lucie. We continue to the beginning of the island, opposite the buildings that are now used as a ship restoration yard.

(3) We now walk along the island and a final bend brings us within sight of the lock keeper's house and the Sainte-Lucie lock.

(4) We leave the path leading to the beach on our left (that will be for later), continue south-west, pass a water point and reach the Sainte-Lucie Lock.

(5) We turn right and go through the lock gates to visit the island (nature reserve). We turn left to begin our visit to the Sainte-Lucie Island nature reserve, opting for the short route (3 km).

(6) At the old Jules salt marshes, we turn right and return to the lock.

(5) We turn left and find the path that leads to the beach.

(4) We turn right and head to the water's edge for a swim at Plage de la Vieille Nouvelle.

(7) From the beach, we rejoin the path to retrace our steps back to the car park (S/E).

Notes

Please note that depending on weather conditions, it can get very hot on the trail (little shade), so remember to bring water and sun protection.
The wind can also make the walk more difficult: the tramontane wind blowing from the north can slow you down on the way back as you will have it against you.
- Water point at the edge of the canal, just within sight of the Sainte-Lucie lock keeper's house.
- Toilets and water point at the Sainte-Lucie lock keeper's house.

Note: Short route: 3 km, long route: 7 km

Beautiful views of the region's typical landscapes (Montagne Noire, ponds, canal, etc.). It took me over four hours to walk to point 4 and back; I think the total duration of this hike exceeds five hours for an average walker.

Very nice route. Quiet and peaceful, especially when there is no wind. Very nice view of the ponds. Be careful of mosquitoes at this time of year, though.

A very pleasant route, with no difficulties. You walk alongside the La Robine canal the whole way, with some shaded sections but also quite a few sunny stretches. In the height of summer, it can get quite hot.
Once you reach the sea, you can go for a swim.
We're right opposite the Port La Nouvelle facilities, but you can move away a little.
St Lucie Island is worth a visit, with its pine tree-lined paths. Nice.
It's a fairly busy route.

Super interesting, long but easy. Remember to use mosquito repellent—we eat as many as they bite us.

Done by mountain bike. The Isle Ste Lucie nature reserve is worth a visit. At the beginning of March, it's a bit difficult to cross the sand without sinking in to get to the beach. Very quiet place.

A lovely, very easy and pleasant walk
It is probably busier at the weekend
If you're coming from Perpignan, it's better to leave from Port la Nouvelle as the car journey is much shorter.

A very beautiful hike in this still unspoilt area. We set off from Les Ayguades (48.5 km).
The slight drawback of starting from this point is the section of country road between Gruissan village and the Mandirac lock.
As mentioned in the hike description, beware of the west wind, which can make the return trip more difficult.

A lovely walk with no elevation gain, but best done on a day with little wind...
We didn't do the 7 but pushed on to Port la Nouvelle.
You can extend the route by starting from Gruissan.
There is a very useful water tap at the Ste Lucie lock.
