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.

One of my favorite cycle paths in the area. It's just fun to whizz along the canal with a mountain bike. The path goes up and down in parts and has some potholes. It's also quite dusty in the summer. If that doesn't bother you, you're in the right place 😁

This small village has assets to showcase. Do not hesitate to linger to visit its church, its old collegiate chapel converted into a media library, its well or its presbytery.

⚓ Écluse du Bagnas – one of the last locks on the Canal du Midi The Écluse du Bagnas is located near Agde at the eastern end of the Canal du Midi. It was built around 1676 and is therefore one of the historic locks from the canal's early days. 📍 Canal kilometer: approx. 235.3 km from Toulouse ⚙️ Type: single lock with one chamber 🌊 Altitude: only about 2 meters above sea level 🚤 Distance to Les Onglous / Étang de Thau: only just under 5 km Historically, the lock chambers here were about 30 meters long and 6 meters wide at the gates. The eastern section of the Canal du Midi was later modernized for larger ships; today, the usable lock dimensions in this area are around 40.6 × 5.85 meters. Its location is particularly interesting: the Bagnas lock is situated in the middle of a wetland and separates different water areas here. Behind it, you are practically on the final straight of the Canal du Midi – via Les Onglous, the canal flows into the Étang de Thau, and from there, there is the connection towards Sète and the Mediterranean Sea. 🌊🇫🇷 After more than 235 kilometers of canal route, you have almost reached the Mediterranean Sea here – a small but historically interesting structure at the end of the Canal du Midi. 🚲👌🏼 Greetings Marcus ✌🏼

Built around 1676, the Bagnas lock is a simple lock on the Canal du Midi, located between Agde and the Étang de Thau. It is one of the last structures on the canal before its outlet at Les Onglous, where the canal joins the lagoon. In the immediate vicinity of Bagnas, a vast coastal wetland, the lock is also associated with a spillway intended to drain excess water.

Pézenas is not just about Molière, even though the playwright stayed there several times between 1650 and 1656 under the protection of the prince de Conti. The city was for a long time one of the most influential in Languedoc: the States of Languedoc met there regularly, and Louis XIII, Richelieu, or the prince de Conti stayed there. While strolling through the narrow streets, keep your eyes open: many doors still retain their original knockers and ironwork, testaments to the skill of Pézenas artisans. A tradition that is perpetuated today by the Musée de la Porte et de la Ferronnerie, unique in France. Finally, one last curiosity: the famous Maison de Molière should not be misleading. Despite its name, there is nothing to confirm that the playwright lived there. Local tradition rather holds that he liked to settle in the barber Gély's shop, where he observed the inhabitants and their foibles, a source of inspiration that is said to have fueled several of his future characters.
