The start and finish of this walk are at Frontignan railway station
(S/E) On leaving the station, head south towards the bascule bridge.
(1) Cross the Canal du Rhône à Sète via this bridge, turn left and walk alongside the canal. Pass under the railway line. Leave Avenue du8e Régiment d’Infanterie on your right and, about twenty metres further on, you’ll come to the start of a footpath.
(2) Follow this footpath, which is shared with cyclists, to the Rond-Point des Étangs, just before another canal. Go round the roundabout on the left.
(3) Cross over the canal and head towards the banks of the Étang des Mouettes, following the various sections of this cycle/footpath.
(4) Stay on the path between the Étang des Mouettes (on the right) and the Étang d’Ingril (on the left). Head towards the harbour master’s office and the small harbour at Frontignan.
(5) Still on the cycle and footpath, continue to the end of the Étang d’Ingril. Use the small footbridge to cross over to the Mediterranean Sea side, onto Plage des Aresquiers
(6) Turn left towards the bridge crossing the Rhône–Sète Canal. About 400 m after the bridge, cross the D114 with care and head for the entrance to a car park.
Yellow signposting
(7) At the end of the car park, take the path named ‘Les Aresquiers’ on the OSM map. Follow the yellow markings and, at a crossroads, take the path on the right, heading north-west into the forest. Join a side track.
(8) Turn left and continue south-westwards, heading towards the pond. Follow the most obvious path and head back north-west, with marshes on your left and vineyards on your right. You’ll come to a crossroads.
(9) Turn left, heading due west along a raised, well-maintained path, and arrive at the edge of a pond in the former salt marshes.
(10) Walk along the edge of the basin until you reach another crossroads.
(11) Turn slightly left and walk naturally along the marsh until you reach the edge of a track suitable for vehicles.
Unmarked
(12) Leave the yellow-marked marsh path on your right. Continue straight on towards the track that runs alongside the canal and curves in a 90° arc. Carry on to the bridge under the D612.
(13) Pass under the D612, follow the railway line via the Chemin des Pielles and then the Chemin des Cheminots, and continue to a bridge under the railway line at the corner of Rue du Bassin.
(14) Turn right onto Rue du Bassin, go under the railway line and, finally, turn left onto Boulevard de la République to return to Frontignan station (S/E).
The first part of the cycle path is interesting because it runs alongside the pond. But it also runs alongside the road... The part in the forest is more interesting.
