The best traffic-free bike rides around Marseillan

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 remarkable structure composed of mobile aqueducts allows boats navigating the Canal du Midi to cross the small river Libron. Created in 1855 by Urbain Maguès, an engineer also responsible for the bridge-canal of Béziers.

⚓ 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 ✌🏼

The Canal du Midi, built in the 17th century under the direction of Pierre-Paul Riquet, connects the Garonne river network to the Mediterranean. A little further on, it joins the Hérault river, near Agde, then continues to the Étang de Thau via the Canal des Onglous. This waterway, a UNESCO World Heritage site, bears witness to the ambitious project conceived in the 17th century to link the Atlantic to the Mediterranean.

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.

After the Bagnas lock, this dirt path follows the Canal du Midi through the landscapes of the Bagnas wetland area. Particularly pleasant to cycle on a gravel bike, it offers an immersion in this coastal environment where reed beds, lagoons, and open spaces alternate.
