The Étang de Thau is the largest lagoon in Occitania and a species-rich inland sea, separated from the Mediterranean by a narrow sandbank. The waters are the center of South French oyster farming, whose hanging mussel beds shape the landscape. As a nautical hub, the lagoon also connects the famous Canal du Midi with the Canal du Rhône à Sète. Along the shore, charming towns line up, such as the fishing town of Sète, the vermouth town of Marseillan, and the oyster towns of Bouzigues and Mèze, which can be perfectly explored via the 53-kilometer-long cycling route around the basin.

The Phare des Onglous marks the eastern end of the Canal du Midi, where its waters join the Étang de Thau after a 240 km journey from Toulouse. Red and white, it has guided boats entering or leaving the canal for over a century. An emblematic place where river heritage and maritime horizons meet.

A remarkable geological site, worthy of the legend of the fairies! The rock that constitutes it is sandstone with a carbonate cement, but it is not limestone. Differential erosion, which wears away the less resistant parts of the rock more quickly, has gradually sculpted its surface and formed natural basins (rounded hollows in which water can accumulate). According to legend, on full moon nights, after the rain, the fairies come to wash their laundry in these small basins carved into the sandstone, before spreading it out on the rocks. In Occitan, the place is called "L’espandidou das Fadas".

The dinosaur egg-laying sites, the red lands, the white rocks, and the Fairy's Waslijn are among the most remarkable geological sites in the municipality. The Fairy's Waslijn is worth the detour as it is an original formation of limestone rocks, deposited at the beginning of the Tertiary era, during the foldings of the Pyrenean-Provençal chain, on a continental plain episodically crossed by rivers.

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.

Painted red and white, the Onglous lighthouse stands at the end of the jetty. Intended to guide boats at night and in foggy weather, it is an architectural marker that adorns the entrance to the Canal du Midi. It was only built around 1850. In the 18th century, a small pyramid of white stones marked the presence of the jetty.
