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.

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.

The Bagnas lock is the last single-chamber lock on the Canal du Midi before Sète, at the end of the canal. Built around 1676, it is located 235.2 km from Toulouse at an altitude of 2 m, between the Étang de Thau to the east and the Hérault river then the Prades lock to the west. It is located in the commune of Agde in the Hérault department in the Occitanie region.
