The canal du Midi

Until the end of this year 2023, works are to be expected on the towpath and/or the bridleway of the Canal du Midi between Carcassonne and Seuil de Naurouze.
Detour are proposed, accompanied by road signs.
A follow-up will be set up as the work progresses to inform users of the reopening of the sectors. Please be careful if you encounter construction equipment.

The Canal du Midi is a canal that stretches for 240 km across the South of France (the “Midi”). It connects Toulouse and the Garonne river to the Etang de Thau, a lagoon on the Mediterranean. Together with the Garonne canal, which is 193 km long, it forms the Canal des Deux Mers which connects the Atlantic Ocean to the Mediterranean Sea.
The Canal du Midi crosses the department of Aude from west to east, flowing through Castelnaudry, Carcassonne and Narbonne.

The canal is fed via a highly sophisticated hydraulic system which includes some of the very first inventions and structures ever used in the field of water management. Of all the locks, bridges, aqueducts and overflow systems, certain features have remained unchanged since their construction.

The canal’s towpath is a popular place to enjoy activities in the great outdoors.

Did you know?

Initially baptised the “Canal Royal de Languedoc”, the canal was renamed by the revolutionaries in 1789 when it became the “Canal du Midi” (meaning “Canal of the South”).

A little history

Creating a waterway link between the Atlantic Ocean and the Mediterranean Sea was for a long time nothing more than a distant dream, until Pierre-Paul Riquet turned the dream into reality.

In the 17th century, after many an engineer had failed to find a solution, he, a salt-tax collector with a passion for science, found a way to connect the two seas.
The waterways that gushed down the Montagne Noire were to be harnessed and carried via channels known as “Rigoles” to join the canal at the Seuil de Naurouze watershed.

The Canal du Midi revolutionised waterborne transportation and the overall flow of traffic in the South of France of the Ancien Régime. Under a royal edict of October 1666, Jean-Baptiste Colbert gave permission for the construction work to start. The canal was built between 1666 and 1681, under the reign of Louis XIV.

Nowadays, the Canal du Midi is one of the oldest canals in Europe to still be in operation.

The Canal de la Robine, which is a side branch of the Canal du Midi, crosses Narbonne and reaches the Mediterranean at Port-la-Nouvelle.

Along the towpath

If you have itchy feet, take to the towpath to explore the banks of the Canal du Midi by bike. Unless you prefer walking, jogging, or just playing French bowls…

These banks are also included in some long-distance hiking and cycling itineraries, notably the Canal des Deux Mers à Vélo (Canal of the Two Seas by Bike), for a gentle adventure travelling between the Atlantic Ocean and the Mediterranean Sea.

A unique experience discovering the visited regions, from the cereal plains and sunflower fields of Lauragais to the vineyards of Minervois, across the Parc Naturel Régional de la Narbonnaise en Méditerranée. Along the way, approved Accueil Vélo services and facilities provide everything you’ll need during your trip.

Return to authenticity and discover nature. But above all, savour each moment.
