Le Canal des 2 Mers à vélo brings together estuary scenery, historic towns and two great waterways on a journey across southern France. The route’s own guide describes an itinerary from Royan to Sète, with choices along the Gironde and an alternative Mediterranean finish at Port-la-Nouvelle.
From Royan along the Gironde
The Atlantic end begins in Royan, where the first stage follows the seafront near Grande Conche before continuing through Meschers-sur-Gironde and Talmont-sur-Gironde. Talmont’s position above the estuary makes it a memorable stop before the route carries on towards the port of Mortagne-sur-Gironde.
This opening stretch mixes cycle paths with small roads and tracks, and its terrain is more demanding than the long canal sections farther east. France Vélo Tourisme advises particular care around Port des Monards and at the crossing near Chez Gautron. Beyond Mortagne, the itinerary continues towards Blaye and its citadel.
The canals towards Toulouse
At Blaye, riders have two ways towards Bordeaux: cross the estuary by ferry to Lamarque or follow the right bank through Bourg. From Bordeaux the route uses the Roger Lapébie cycleway towards Créon, passing former railway stations along an old railway line.
The Canal de Garonne gives the middle of the journey its waterside character. Highlights include the canal bridge at Agen and the approach to Toulouse, where the Canal de Garonne meets the Canal de Brienne and the Canal du Midi at Ponts-Jumeaux. The route continues along the Canal du Midi towards Castelnaudary and Carcassonne.
Choosing a Mediterranean finish
At Le Somail the itinerary offers a choice. One branch continues towards Capestang, Béziers and Sète; the other heads towards Narbonne and Port-la-Nouvelle. On the Sète branch, the route guide highlights the Malpas tunnel, the Fonseranes locks and the Orb canal bridge near Béziers.
Farther east, the canal reaches the Étang de Thau at the Onglous lighthouse. The final approach to Sète includes the Lido greenway beside the sea. The alternative via Narbonne uses the Canal de Jonction and the Canal de la Robine, with a shared-road section through Cuxac-d’Aude.
Planning the ride
The route can be ridden in either direction. Choose stages according to the places you want to visit and consult the current stage descriptions before travelling: the Canal du Midi section is not fully developed as a cycle route.
The route’s equipment guide recommends a well-equipped hybrid or mountain bike for the complete itinerary. It warns that sections from Port-Lauragais towards Sète can be uneven or affected by roots, and that a trailer can be difficult there. Heavy rain can bring sudden flooding along the canals, while summer heat is another consideration.
