The Canal du Midi, a 17th-century hydraulic engineering masterpiece and UNESCO World Heritage site, offers one of the most pleasant family cycling routes in the south of France: a flat towpath shaded by a century-old avenue of plane trees, punctuated by historic locks and typical villages.
A shaded route between locks and villages
Starting in Carcassonne, whose fortified medieval city alone is worth the detour, the towpath follows the canal east toward Trèbes, offering near-continuous shade thanks to the plane trees planted when the canal was built — a real asset for riding with kids even in peak summer heat.
The route continues toward Marseillette, crossing several historic locks whose mechanism, largely unchanged since the 17th century, often fascinates kids. Allow around 30 km round trip for this stretch, with the option to easily shorten it by stopping at Trèbes.
How to approach the ride as a family
The near-total lack of elevation gain (20 m total) and the generally smooth surface of the towpath make this route accessible from a very young age, in a trailer or child seat for toddlers, and independently from around 6-7 years old for older kids. The continuous shade from the plane trees allows comfortable riding even in the middle of a summer day, unlike many fully exposed routes in this warm region.
The locks, regularly spaced along the route, make good rest stops for watching pleasure boats pass through — an activity that generally delights kids.
When to go
The ideal window runs from April to October. Spring and early autumn bring lighter crowds on the towpath, while summer, despite sometimes intense heat in the Aude, remains rideable thanks to the canal’s generous shade.
Good to know
Carcassonne, a major tourist city well served by transport (TGV station, airport), has a wide choice of accommodation and several bike rental shops used to families, making it a convenient starting point for exploring the Canal du Midi over half a day or more.
