Pointe des Onglous in Marseillan in the Hérault department constitutes the unique site where the Canal du Midi ends and leads to the pond of Thau. At the end of this point is a small structure, the Onglous lighthouse, which marks the exit from the canal. There extends the port of Onglous as well as a base of the Glénans sailing school. The area also houses a hiking trail that allows reaching the end of Pointe des Onglous.
