Walled cities like Aigues Mortes, the fishing port of Sete, the modern resorts of Cap d'Agde and the Mediterranean coast, the lake of Thau with its oyster farms make this an absolutely spectacular and memorable trip. 

One week out and back cruise : 

Saint Gilles to the Etang de Thau and back. This is one of our very favourite cruises and the weather should be excellent throughout the season. There are very few locks and cruising is really laid back here with time for swimming and fishing. The Camargue, Aigues Mortes, Sete, Marseillan, the Etang de Thau, these are all treasures not to be missed.
146 km, no locks, 27 hours round trip cruising time
H2O recommended first time trip

One week, one way : 

Saint Gilles - Port Cassafières or vice-versa.
109 km, 2 locks, 20 hr one-way cruising time
