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

It is difficult to imagine that between Agde and Marseillan lies one of the largest protected wetland areas on the coast. The Bagnas nature reserve, the former delta of the Hérault, long exploited for salt and then for viticulture, is today a space entirely dedicated to fauna and flora. Between lagoons, salt marshes and reed beds, this changing landscape hosts hundreds of migratory bird species each year.

A remarkable geological site, worthy of the fairy legend! It is actually a sandstone (clastic rock) with a carbonate cement and not a limestone. Differential erosion has shaped this landscape into natural basins.

The dinosaur egg-laying sites, the red lands, the white rocks, and the Étendoir des fées are among the most remarkable geological sites in the municipality. The Étendoir des fées is worth the detour as it is an original formation of limestone rocks, deposited at the beginning of the Tertiary era, during the folding 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.

It is located in the commune of Agde in the Hérault department in the Occitanie region.
