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.

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.

Sublime little fishing port! Intimate, little known, you will be in the heart of nature. Let yourself be invaded by the atmosphere of the place between the Mediterranean Sea, the Aude river and the Vendres wetland classified Natura 2000.

The single lock of Portiragnes opens onto the Agde reach downstream. It is a typical area of the landscapes of the Languedoc coastal strip. Indeed, from this lock, the surface of the canal is at an altitude of only 1 meter above sea level. It runs alongside wetlands of former salt ponds (la grande Maïre), where we find rich fauna and flora (bulls, horses, waders, amphibians, reeds...) and some pine groves. These places are conducive to the establishment of numerous campsites.

The Cassafières port, established in the 1980s in a basin right next to the campsites, allows you to rent a boat to navigate the canal and visit the Languedoc coastal plain.

The round lock of Agde is the most original on the canal. Built in 1675-1676. It was put into operation in 1678 when the canal from Béziers to the Étang de Thau was opened to navigation. A particular situation, an original response: it was decided to build a round lock with three gates. The first opens towards the city of Sète and the Étang de Thau via a short passage on the Hérault; the second opens onto the canal coming from Béziers; the third opens onto the small canal which allows small boats to reach the city of Agde and its maritime port and then Grau d'Agde. The round lock was commissioned in 1678 when navigation opened between the Étang de Thau and Béziers. It originally measured 30 meters in diameter with a depth of 5.20 meters in the center. Thanks to this round lock and the low canal, small maritime boats can come onto the canal!

It is the « Pont Saint-Joseph », but for a long time everyone has called it « The Three Eyes Bridge ». It sounds more poetic. The Three Eyes Bridge is a very pleasant structure: a main arch to let boats pass, and two smaller ones, one of which lets water through, and the other the towpath. It must not have been easy in the time of bargemen (towing by horses) because it was necessary to detach, then reattach when the obstacle had been passed. Here it is obvious, but it is the case for almost all the bridges on the Canal du Midi. It must be said that most of the time, the boat continued on its momentum and was reattached on the other side. Another peculiarity of this place is that there are two spillways on either side of the bridge.
