The Canal du Rhône à Sète (French pronunciation: [kanal dy ʁon a sɛt]; lit.

[2] It connects with the Canal du Midi through the Étang de Thau.

There is, however, no access to the Rhône at Beaucaire as the lock has been closed since the Vallebregues barrage was built.

In recent years major work has been undertaken to upgrade the canal so it can now be used by 1200t convoys instead of the previous 350t barges.

Most notable are a stretch of canal bypassing the town of Aigues-Mortes with its railway swing bridge and a direct canal link to the port of Sète eliminating the passage of lifting and swing bridges in Frontignan and Sète.
