The best hikes from bus stations in Occitania

The Grande Maïre educational trail allows you to enjoy this vast wetland. You will see flamingos and other wading birds, which come to take advantage of the richness of the soil to feed.

La Rivierette is a small lagoon connected to Grande Maïre by a network of canals. This wetland is home to a rich fauna of numerous birds and aquatic species.

The name “Estagnol” evokes a small pond (a name that echoes the many wetlands that characterize this part of the Hérault coast). Unfortunately, the pond is not visible from the greenway and remains hidden by vegetation. Passing here by bike, you cycle alongside one of the most famous hydraulic structures in France: the Canal du Midi, designed by Pierre-Paul Riquet in the 17th century to connect the Atlantic to the Mediterranean. In Portiragnes, the canal reaches a very low coastal plain, close to ancient ponds and wetlands. A little anecdote about the area: this geography posed a real challenge for the canal builders. In this low-lying plain, during heavy rains or floods, water could quickly accumulate. It was therefore necessary to allow excess water to cross or bypass the canal without damaging it. The engineers thus developed various hydraulic structures, notably weirs, which allow excess water to be discharged into the neighboring natural areas.

🌿 L’Estagnol near Portiragnes A small, somewhat hidden wetland and pond area near Portiragnes, which could easily be overlooked on a tour through the area. 🌿🚲 The name „Estagnol“ comes from Occitan and denotes a small pond or body of water – and that is exactly what you find here: densely overgrown banks, reeds, and a calm water surface in the middle of the Mediterranean landscape. Especially by bike, L’Estagnol is a nice little detour when you are traveling between Portiragnes, the vineyards, and the Canal du Midi. Not a spectacular destination, but rather one of those quiet places that make up the charm of the area. 😊👌🏼 Greetings Marcus ✌🏼

With an average depth of only 55 cm, the Étang de Gruissan is more of a lagoon than a true "lake". Its brackish waters depend on exchanges between the sea, canals, and watershed, while winds can significantly alter its functioning. It is part of the six lagoons of the Narbonne complex, protected notably for the richness of their wetlands and their importance for birds. A few kilometers away, the remains of Île Saint-Martin recall another era: between the 2nd century BC and Roman antiquity, these lagoons were part of Narbonne's vast port system.

From this narrow strip of land, the Gruissan lagoon landscape reads almost like a succession of parallel bands: the wetlands and secondary ponds to the south, the path on which we are, the Sainte-Marie canal, then the Gruissan pond to the north. The Sainte-Marie canal bears witness to the old hydraulic development of this coastal plain. Integrated into a network of canals intended to manage its waters, it notably contributed to the draining of the old salt pond. Today, it contributes to the freshwater supply of the Gruissan pond and thus participates in the salinity variations of the lagoon.

This viewpoint offers an unobstructed view of the Barberousse Tower, perched on its limestone promontory on the edge of the Gruissan pond. The current tower, built between 1245 and 1247 by the Archbishop of Narbonne, Guillaume de Broa, is the main remnant of the medieval castle that monitored maritime access to the Narbonne sector.

At the Portiragnes lock, you enter a section almost at sea level, where the canal crosses former salt marshes and wind-swept wetlands. Built at the end of the 17th century, this single lock is notable not only for its shape but also for the landscape it heralds: that of the Aude and Hérault coastline.
