Beach area of Marseillan, here mainly surfers and walkers mingle, sharing the area with cyclists. Lovely view of the Étang de Thau.

A small lighthouse, a jetty, and blue as far as the eye can see. The Pointe des Onglous, where the Canal du Midi flows into the Thau lagoon, is an ode to contemplation. The pond reveals itself in 360°, as does its oyster farming vocation, with the azure sky and the silhouette of Mont Saint-Clair in the background. A picture that also features the town and port of Marseillan, the wild expanses of the Maldormir district, the tip of the lido, and old salt pans.

Nice spot, especially for stopping to eat as there are benches with a view (and even picnic tables for the more demanding): perfect!

An incredible number of (artificial) mussel beds...there must be millions of mussels.

Excellent view of the pond opposite Sète. The 60-kilometer cycle loop around the basin allows you to explore the largest pond in Occitanie up close.

No access in all directions. Lake partially visible here and there. A few nice paths and trails in the area, but nothing else. Not really recommended.

Magnificent track that makes the junction between Meze - Balaruc le Vieux, the view of the ponds is superb. Attention towards balaruc many walkers the Weekend on the shared track. I advise you to go to the end of the track in Meze to admire the view and have a coffee while wandering on the port
