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.

Here, the landscape tells the story of the sea, the river, and human history. Formerly a space for salt pans and then cultivation, the Bagnas became a nature reserve in 1983. Between ponds, reeds, and salt marshes, this vast wetland between Agde and Marseillan is today one of the major refuges for migratory birds on the Mediterranean coast.

It is difficult to imagine that waterways cross here like at a crossroads. Built in 1676 by engineer Pierre-Paul Riquet, the round lock of Agde is unique on the Canal du Midi: its circular shape and its three gates allow boats to choose between three different directions. Depending on their course, they head back towards Béziers, towards Agde, or towards the Étang de Thau. An ingenious river junction at the entrance to the town.

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.

It is nicknamed the "Bridge of Three Eyes". Three openings designed within the logic of the Canal du Midi: navigation, water drainage, and continuity of local circulation. A work from Pierre-Paul Riquet's project, to be discovered in the landscape between Vias and Agde.

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.
