The Canal du Midi, a masterpiece listed at UNESCO

The Canal du Midi is among the oldest canals in Europe still in operation. Listed as a UNESCO World Heritage site since 1996, it was dug between 1666 and 1681 under the impetus of Pierre-Paul Riquet, an engineer from Béziers. The structure connects the Garonne to the Mediterranean and allowed, at the time, to transport wheat and goods without having to go around Spain by boat.

With a length of 240 km, it crosses 63 locks and several canal bridges, including the famous structure that passes over the Orb at Béziers. Its banks, once planted with more than 42,000 plane trees, guarantee precious shade for walkers. The canal now lives to the rhythm of river tourism and welcomes thousands of boaters from all over Europe each year.

What to do along the Canal du Midi?

The Canal du Midi lends itself to all desires, from sporty to contemplative. The greenway that runs along its banks makes it an ideal playground for families, cyclists and nature lovers. Here are the main activities to practice along the canal:

Cycling on the greenway takes you flat for nearly 240 km, with the constant shade of plane trees.
A barge cruise can be booked for a day or a week, departing from Toulouse, Castelnaudary or Béziers.
Hiking follows the towpath and crosses wine-growing villages and beautiful old locks.
As for swimming, you can enjoy the nearby water sports facilities such as Cavayère lake near Carcassonne.
Wine enthusiasts taste AOC Minervois, Cabardès or Picpoul de Pinet on the hillsides south of the canal.

Claire’s tip: for a first trip with young children, I recommend combining two days of cycling between Carcassonne and Trèbes, perfectly flat, with a relaxing afternoon at the campsite pool. You avoid fatigue, and the children keep an excellent memory of their discovery of the canal.

The unmissable stages, from Toulouse to Sète

From Toulouse to Sète, the canal crosses three departments and alternates between pink city, Cathar country and Mediterranean vineyards. Here are the main stages to integrate into your itinerary:

Toulouse marks the official start of the canal and offers boat rentals from the Saint-Sauveur port, in the city center.
Castelnaudary, world capital of cassoulet, houses the Grand Basin, one of the largest expanses of water on the canal.
Carcassonne, listed at UNESCO, combines medieval city and the highest point of the canal at the Naurouze threshold.
At Béziers, the 9 locks of Fonseranes overcome 21.5 meters of elevation and are one of the main attractions.
Agde stands out with its round lock, unique in France, which has three exits for boats.
Sète and the Thau pond close the journey, between fishing villages, oyster farms and Mediterranean beaches.

Where to stay to discover the Canal du Midi with family?

The Canal du Midi crosses Languedoc, a region ideal for combining culture and bathing! Several campsites with water park in Hérault, in Aude and Haute-Garonne are located near the canal. You will find establishments just steps from Béziers, Agde, Carcassonne or the Mediterranean coast.

In the heart of Languedoc, you can easily reach the main stages of the canal.
