The Canal du Midi is a 240 km UNESCO World Heritage waterway built in the 17th century connecting Toulouse to the Mediterranean Sea at Sète. Lined with thousands of plane trees, it offers one of France's most scenic cycling routes and is popular for barge holidays. Key sections pass through Carcassonne, Béziers (with its famous nine-lock staircase), and the wine country of Hérault.
The Canal du Midi is a 240 km masterpiece of 17th-century engineering, threading through the Occitanie landscape of southern France from the Port de l'Embouchure in Toulouse to the Mediterranean at Sète. Conceived by Pierre-Paul Riquet and completed in 1681, it was the longest canal in Europe at the time of construction and remains a UNESCO World Heritage Site, celebrated for its integration of function and beauty. The canal's defining visual character comes from the double avenue of plane trees planted along much of its length — now a living heritage under threat from plane-tree canker disease, with replanting programs underway. The route passes through an extraordinary range of landscapes: the suburban parks of Toulouse, the wine country of the Minervois and Languedoc, the fortified city of Carcassonne reflected in the still water, and the commercial port of Béziers where the famous nine-lock staircase of Fonserannes lifts boats 21.5 metres. Cycling the towpath is the most popular way to experience the canal without a boat: the 340 km ViaRhôna/Canal du Midi cycling route is mostly flat and shaded, with key rental hubs in Toulouse, Carcassonne, and Béziers. Barge holidays — renting a self-drive houseboat for a week — remain the classic way to experience the canal at its unhurried best; bookings for peak summer are typically required six to twelve months ahead. Sections near Capestang and Poilhes, away from the tourist hotspots, offer a tranquil canal experience with few other boats.

The towpath is largely flat and paved in key sections near major towns, making it accessible for wheelchair users and adapted bikes in those areas. Remote sections can be unpaved gravel. Barge operators can advise on vessel accessibility for mobility-impaired guests.
